Description

Technical Field

[0001] This utility model belongs to the field of drilling machinery technology, specifically relating to an automatic drilling device for columnar moxibustion materials. Background Technology

[0002] Moxibustion is a traditional Chinese medicine therapy that uses burning moxa sticks to stimulate the flow of Qi (vital energy) and regulate disordered physiological and biochemical functions in the body, thereby achieving the purpose of preventing and treating diseases. In moxibustion treatment, the moxa stick acts as a combustion carrier, emitting light, heat, and smoke. The shape of the moxa stick is determined by the method of application and the application scenario. Some applications require the use of perforated moxa sticks. For example, in warm needle therapy, the moxa stick is fixed to the acupuncture needle, and the fine holes inside the moxa stick stabilize it on the needle handle, preventing shaking during acupuncture. Additionally, in reverse-flow moxibustion, the axial holes in the moxa stick allow the moxa smoke to flow downwards through the skin, directly acting on acupoints, reducing smoke diffusion and increasing the utilization rate of moxa smoke and heat. Furthermore, when used with moxibustion boxes or warm moxibustion beds, the holes inside the moxa stick are needed to accommodate positioning pins or other structures to limit the position of the moxa material.

[0003] Currently, the moxa sticks used in warm needle therapy typically have a diameter of 5-12 mm, while those used in backflow smoke moxibustion patches are typically 7 mm in diameter. Moxa sticks used with moxibustion boxes or warm moxibustion beds usually have a larger diameter. There are two processing methods for producing moxa sticks with axial holes: one is to press moxa wool into cylinders using high temperature and pressure, forming the outer shape and internal channels of the moxa stick through the cooperation of convex and concave dies; the other is to wrap moxa wool in mulberry paper or cotton paper, roll it into shape, and then cut and punch holes. The pressed moxa sticks undergo high temperature and pressure, which damages some of the volatile oils in the moxa wool and results in high compactness, leading to slower burning. This method is suitable for small-diameter moxa sticks used in oxygen-rich environments. For moxa sticks with a diameter greater than 3.5 cm, pressing easily causes material to scatter, and the compactness cannot be adjusted, which is detrimental to use and moxibustion effects. Therefore, for larger-diameter moxa sticks with holes, the punching method is used.

[0004] Traditional manual drilling methods suffer from low efficiency, misaligned holes, and poor safety. Patent application CN202122174012.4 discloses a moxa stick drilling device for warm acupuncture therapy, featuring a threaded needle hole and a drilling needle with external threads. Drilling is achieved by rotating the drilling needle, which improves safety but remains inefficient. Patent application CN202221495502.2 discloses a moxa stick drilling device including a housing, a pressure plate, and a container for holding moxa sticks. A drilling needle is fixedly mounted on the pressure plate, and the needle punches downwards to create a hole. This method reduces the difficulty and requirements of the drilling operation, but the direct downward punching exerts impact on the outer wrapping paper of the moxa stick, potentially causing it to tear. Furthermore, the loose fibers of moxa wool are prone to deformation of the hole due to material rebound after punching. These problems have spurred the development of moxa stick drilling machines, aiming to improve automated production efficiency through mechanical design. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic drilling device for columnar moxibustion materials. By using a drilling component that moves up and down and a front push plate and a moving baffle that move back and forth, drilling and conveying are realized, thereby improving the automation of columnar moxibustion material processing.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An automatic drilling device for columnar moxibustion materials includes a frame and a drilling assembly for drilling. A lifting assembly is mounted on the frame to move the drilling assembly up and down. The drilling assembly includes a drill bit, and a worktable is vertically positioned below the drill bit. With the direction of the worktable closest to the frame as the front, a push plate is positioned on the front side of the worktable. Moving baffles are symmetrically positioned on the left and right sides of the push plate. The push plate and the two moving baffles together form a drilling station on the worktable, located at the position of the drill bit. Below, two movable baffles limit the left, right, and rear sides of the columnar moxibustion material located at the drilling station; the upper part of the front push plate is connected to an upper baffle that limits the upper side of the columnar moxibustion material, and the upper baffle is provided with a first through hole for the drill bit to pass through; a first cylinder that moves the front push plate back and forth is connected between the front push plate and the frame, and a second cylinder that moves the movable baffle back and forth is connected to the rear side of each of the two movable baffles; a discharge port is provided on the rear side of the drilling station, and the drilled columnar moxibustion material is pushed to the discharge port by the front push plate and falls from the discharge port.

[0008] This invention uses a lifting assembly to move the drilling assembly downwards to drill holes in the columnar moxibustion material located at the drilling station. After drilling, the lifting assembly moves the drilling assembly upwards, causing the top of the columnar moxibustion material to hit the upper baffle and detach from the drill bit, remaining at the drilling station. Subsequently, two second cylinders pull two moving baffles backwards, and the first cylinder pushes the front push plate backwards, allowing the drilled columnar moxibustion material to be delivered to the discharge port and fall from it. Then, the first cylinder pulls the front push plate forward to reset at the drilling station, and one of the second cylinders pushes the moving baffle connected to it forward to the drilling station, sending the columnar moxibustion material to be drilled into the open side of the drilling station (i.e., the columnar moxibustion material is sent into the drilling station from the moving baffle that has not been reset to the drilling station). Then, the second cylinder is controlled to push the moving baffle forward to reset to the drilling station, and then the drilling of the columnar moxibustion material is repeated for the next round.

[0009] The drill bit extends longitudinally, and in order to allow the drill bit to completely pass through the columnar moxibustion material to form a through hole, a groove is provided on the worktable directly below the drill bit so that the bottom of the drill bit can move downward to the groove.

[0010] In order to clean the surface of the drill bit in a timely manner, a blower is provided above the upper baffle. One end of the blower is located above the through hole, and the other end of the blower is connected to a fan for blowing and cleaning the drill bit after drilling and moving upward.

[0011] To address the deformation of the borehole caused by material springback, the surface temperature of the drill bit is set to 200-350°C during drilling to form a carbonized layer on the borehole surface, thereby increasing the stability of the drilled structure.

[0012] A preferred method for heating the drill bit is as follows: a cover plate is provided above the front push plate, the cover plate has a second through hole for the drill bit to pass through, and an electromagnetic induction heater is installed at the cover plate. The electromagnetic induction heater includes a coil arranged around the second through hole for heating the drill bit that moves through the second through hole.

[0013] To better enable the drilling assembly to move up and down, the lifting assembly includes a guide rail located at the rear of the frame. The guide rail extends longitudinally, and a mounting bracket is slidably connected to the guide rail. An actuator is mounted on the frame to drive the mounting bracket to reciprocate linearly along the guide rail.

[0014] To better complete drilling, the drilling assembly includes a housing mounted on the rear side of the mounting frame, a motor mounted on the housing, a transmission mechanism for transmitting torque mounted on the output shaft of the motor, a rotating shaft mounted on the output end of the transmission mechanism, the rotating shaft extending longitudinally and coaxially mounting the drill bit, and the motor driving the drill bit to rotate through the transmission mechanism and the rotating shaft.

[0015] To achieve dual-station drilling, the transmission mechanism includes a first transmission component, a transmission shaft, and a second transmission component connected in sequence. The transmission shaft extends longitudinally, and there are two rotating shafts located on the left and right sides of the transmission shaft, respectively, and the two rotating shafts are arranged symmetrically. The motor output shaft drives the transmission shaft to rotate through the first transmission component, and the transmission shaft drives the two rotating shafts to rotate through the second transmission component.

[0016] In order to allow the cylindrical moxibustion material to be punched to enter the punching station smoothly, the left or right side of the punching station is provided with opposing side baffles, and a channel is formed between the front and rear side baffles to allow the cylindrical moxibustion material to be fed into the punching station.

[0017] To further improve the automation of drilling, a first conveyor for conveying moxibustion materials to be drilled is provided on one side of the workbench with a side baffle, and a second conveyor for conveying already drilled moxibustion materials is provided below the discharge port of the workbench.

[0018] Preferably, the upper baffle is parallel to the workbench surface, and the distance between the upper baffle and the workbench surface is not less than the axial dimension of the columnar moxibustion material; the cross-section of the movable baffle is L-shaped, and the cross-section of the drilling station is rectangular; the cylinder of the first cylinder is mounted on the frame, and the end of the piston rod of the first cylinder is perpendicularly connected to the front push plate; an end plate is installed on the rear side of the workbench surface, the cylinder of the second cylinder is mounted on the end plate, and the end of the piston rod of the second cylinder passes through the end plate and is perpendicularly connected to the rear side of the movable baffle.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The automatic drilling device, through the cooperation of the lifting assembly and the drilling assembly, enables the drill bit to drill downwards and reset upwards, facilitating automated control and replacing traditional manual drilling operations. Simultaneously, the forward and backward movement of the front push plate and the moving baffle allows for the automatic transfer of the drilled columnar moxibustion material, saving manpower. The automatic drilling device can process through holes and clean the drill bit surface promptly, ensuring drilling continuity. By maintaining a certain temperature (200~350℃) on the drill bit, carbonization treatment of the hole surface is achieved simultaneously with drilling, helping to maintain the hole shape and preventing deformation caused by material springback. The drilling station and drill bit size can be adjusted and replaced according to actual requirements, improving applicability. Furthermore, this invention uses automatic mechanical drilling, which facilitates product quality standardization and helps reduce the defect rate. Attached Figure Description

[0030] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model will be further described below in conjunction with specific embodiments and accompanying drawings. However, the embodiments are intended to explain this utility model and should not be construed as limiting this utility model. Where specific technologies or conditions are not specified in the embodiments, they shall be carried out in accordance with the technologies or conditions described in the literature in this field or in accordance with the product manual. Example 1

[0031] An automatic punching device for columnar moxibustion materials, such as Figures 1-5 As shown, the device includes a frame, which includes a base 101. Vertical support plates 102 are arranged on the base 101 in a left-right orientation. A horizontal top plate 104 is fixed to the top of the left and right support plates 102. An mounting plate 103 is fixed to the rear side of the left and right support plates 102. The mounting plate 103 is perpendicular to the support plates 102.

[0032] A lifting assembly is installed on the frame. The lifting assembly includes a guide rail 201 located on the rear side of the frame. The guide rail 201 includes two tracks arranged opposite each other, one on the left and one on the right, respectively, on the left and right sides of the mounting plate 103, and the tracks extend vertically. A mounting frame 202 is slidably connected to the guide rail 201. The front part of the mounting frame 202 passes horizontally through the mounting plate 103 and is located between two support plates 102. The mounting plate 103 has an opening 105 for the mounting frame 202 to move up and down. A third cylinder 203 (or a hydraulic cylinder) is installed on the frame to drive the mounting frame 202 to reciprocate up and down along the guide rail 201. The cylinder of the third cylinder 203 is installed on the top plate 104. The piston rod of the third cylinder 203 extends downward vertically and is connected to the front part of the mounting frame 202. The mounting frame 202 moves up and down under the pushing and pulling action of the third cylinder 203.

[0033] The rear side of the mounting bracket 202 is vertical, and a drilling assembly for drilling is mounted on the rear side of the mounting bracket 202. The drilling assembly can move up and down through a lifting assembly. The drilling assembly includes a housing mounted on the rear side of the mounting bracket 202. The housing includes a first housing 301 and a second housing 302 connected vertically. A motor 303 is mounted on the rear part of the upper surface of the first housing 301. The output shaft of the motor 303 extends vertically downward into the first housing 301 and is connected to a transmission mechanism for transmitting torque. The transmission mechanism includes a first transmission assembly (not shown in the figure, but can be a conventional gear transmission assembly, belt transmission assembly, or chain transmission assembly) disposed within a first housing 301, a second transmission assembly (selected as a gear transmission assembly) disposed within a second housing 302, and a transmission shaft 304 connecting the first transmission assembly and the second transmission assembly; both the first transmission assembly and the second transmission assembly 305 can be constructed using conventional techniques existing in the art, i.e., the first transmission assembly includes a first driving wheel and a first driven wheel meshing with each other, and the second transmission assembly 305 includes a second driving wheel and two second driven wheels meshing with the second driving wheel; the first driving wheel is coaxially mounted on the output shaft of the motor 303. In the first housing 301, the axial centerline of the drive shaft 304 coincides with the axial centerline of the second housing 302. The top of the drive shaft 304 extends upward into the first housing 301. The first driven wheel is coaxially mounted on the top of the drive shaft 304, and the bottom of the drive shaft 304 extends downward into the lower part of the second housing 302. The second driving wheel is coaxially mounted on the lower part of the drive shaft 304. Rotating shafts 306 are mounted symmetrically on the bottom of the second housing 302, with the two rotating shafts 306 arranged symmetrically about the axial centerline of the drive shaft 304. The second driven wheel is coaxially mounted on the upper part of the rotating shaft 306. The drive shaft 304 drives the two rotating shafts 306 to rotate via a second gear transmission assembly 305. The first housing 301 and the second housing 302 are used to install and protect the transmission mechanism and the rotating shafts. The shapes of the first housing 301 and the second housing 302 are not specially designed. A drill bit 307 is coaxially mounted on the bottom of the rotating shaft 306. The motor 303 drives the drill bit 307 to rotate through the first gear transmission assembly, the transmission shaft 304, the second gear transmission assembly 305, and the rotating shaft 306 in sequence. The drill bit 307 can be a twist drill or a spindle drill. Ordinary commercially available drill bits can be used depending on the actual product. The installation and connection of the drill bit 307, the rotating shaft 306, and the transmission shaft 304 are all conventional operations in the prior art and can be easily implemented by those skilled in the art, so they will not be described in detail.

[0034] A horizontal worktable 8 is provided below the drill bit 307, and support legs 9 are provided at the four corners of the bottom surface of the worktable 8 for supporting the worktable 8. A vertical push plate 4 is provided on the front side of the worktable 8, a first movable baffle 5 is provided on the left side of the push plate 4, and a second movable baffle 6 is provided on the right side of the push plate 4; the cross-section of the first movable baffle 5 and the second movable baffle 6 is L-shaped, and the first movable baffle 5 and the second movable baffle 6 are arranged symmetrically from left to right; through the enclosure and limitation of the push plate 4, the first movable baffle 5 and the second movable baffle 6, a drilling station with a rectangular cross-section (double station, the length is twice the width) is formed on the worktable 8, and the drilling station is located below the drill bit 307. The axial centerlines of the two drill bits 307 pass through the center point of each station in the dual-station configuration. The front side plate 4 limits the front of the moxibustion column at the drilling station. The first movable baffle 5 limits the left and rear sides of the moxibustion column at the drilling station. The second movable baffle 6 limits the right and rear sides of the moxibustion column at the drilling station. There may be no gap between the rear ends of the first movable baffle 5 and the second movable baffle 6, or there may be a gap. If there is a gap between the rear ends of the first movable baffle 5 and the second movable baffle 6, this gap should be less than the width of the drilling station. An upper baffle 7 is connected to the upper part of the front push plate 4. The upper baffle 7 is parallel to the worktable surface 8, and the distance between the upper baffle 7 and the worktable surface 8 is not less than the axial dimension of the moxibustion column. The upper baffle 7 has a first through hole 16 for the drill bit 307 to pass through. A pad 17 is embedded and fixed at the drilling station of the workbench 8. The upper surface of the pad 17 is flush with the upper surface of the workbench 8. The pad 17 has a second through hole that corresponds vertically to the first through hole 16, so that a groove 18 is formed on the workbench 8 directly below the drill bit 307. This allows the bottom of the drill bit 307 to move downward to the groove 18, so that the drill bit 307 completely passes through the moxa stick to form a through hole. In order to allow the moxa stick to be drilled to enter the drilling station smoothly, a pair of opposing side baffles 15 are provided on the right side of the drilling station. The two side baffles 15 form a channel to guide the moxa stick to the drilling station.

[0035] A first cylinder 11 is connected between the front push plate 4 and the mounting plate 103 to move the front push plate 4 back and forth. The cylinder barrel of the first cylinder 11 is mounted on the mounting plate 103, and the piston rod end of the first cylinder 11 is perpendicularly connected to the front push plate 4. A vertical end plate 10 is mounted on the rear side of the worktable 8. A second cylinder 12 is connected to the rear side of both the first moving baffle 5 and the second moving baffle 6. The second cylinder 12 is parallel to the first cylinder 11, and the cylinder barrel of the second cylinder 12 is mounted on the end plate 10. The piston rod end of the second cylinder 12 located on the left passes through the end plate 10 and is perpendicularly connected to the rear side of the first moving baffle 5. The piston rod end of the second cylinder 12 located on the right passes through the end plate 10 and is perpendicularly connected to the rear side of the second moving baffle 6. The first moving baffle 5 and the second moving baffle 6 move back and forth through the second cylinder 12. The rear side of the drilling station is provided with a discharge port 14. The front-to-back width of the discharge port 14 is greater than that of the drilling station, and the left-to-right length of the discharge port 14 is also greater than that of the drilling station. After the drilling is completed, the first moving baffle 5 and the second moving baffle 6 move backward to the end plate 10. At the same time, the front push plate 4 pushes the moxibustion column backward, so that the moxibustion column after drilling falls from the discharge port 14.

[0036] To clean the surface of the drill bit 307 in a timely manner, a blower pipe 13 is provided above the upper baffle 7. The blower pipe 13 includes a rigid first pipe section 1301 and a flexible second pipe section 1302. The front end of the first pipe section 1301 is located on the front side of the front push plate 4, and the rear end of the first pipe section 1301 passes through the front push plate 4 horizontally and extends to the top of the first through hole 16. The second pipe section 1302 is connected to the front end of the first pipe section 1301, and the front end of the second pipe section 1302 passes through the mounting plate 103 and is connected to a fan (the fan is located on the front side of the mounting plate 103, not shown in the figure). The fan blows air through the blower pipe 13 to clean the drill bit 307 that has completed drilling and moved upward.

[0037] The working process of the above-mentioned automatic punching device is as follows:

[0038] Before drilling, the mounting bracket 202 connected to the drilling assembly is located on the upper part of the guide rail 201. The first cylinder 11 is not extended, the front push plate 4 is located on the front side of the drilling station, the second cylinder 12 located on the left side is extended, the first moving baffle 5 serves as the left rear side of the drilling station, the second cylinder 12 located on the right side is not extended, and the second moving baffle 6 is located on the right rear side of the discharge port. That is, at this time, the front side of the drilling station is blocked and limited by the front push plate 4, the left side and the left rear side of the drilling station are blocked and limited by the first moving baffle 5, and the right side of the drilling station is open. Then, the moxa sticks to be drilled enter the dual-station drilling position sequentially through the channel formed between the front and rear side baffles 15. The second cylinder 12 on the right extends, and the second moving baffle 6 moves forward to the right rear side of the drilling position, thus limiting the two moxa sticks at the drilling position. Next, the third cylinder 203 extends downward, pushing the mounting bracket 202 downward along the guide rail 201. As the drilling assembly moves downward, the motor 303 drives the drill bit 307 to rotate, that is, the drill bit 307 drills downward and... The drill bit 307 passes through the first through hole 16 and the moxa stick located at the drilling station, and then drills downwards to the groove 18 to drill the moxa stick at the drilling station. Then, the third cylinder 203 resets upwards, pulling the mounting bracket 202 upwards along the guide rail 201. As the drilling assembly moves upwards, the top of the moxa stick hits the upper baffle 7 and falls off the drill bit 307, remaining at the drilling station. The blower cleans the upward-moving drill bit 307 by blowing air through the air pipe 13. After the drilling assembly resets upwards with the lifting assembly, the two second... Cylinder 12 pulls the first moving baffle 5 and the second moving baffle 6 backward, and the first cylinder 11 pushes the front push plate 4 backward (the extension speed of the first cylinder 11 is slightly slower than the reset speed of the second cylinder 12), so that the drilled moxa stick is sent backward to the discharge port 14 and falls from the discharge port 14, completing the drilling of the moxa stick; then, the first cylinder 11 pulls the front push plate 4 forward to move to the drilling position and resets, and the second cylinder 12 on the left pushes the first moving baffle 5 forward to move to the drilling position, and repeats the next round of moxa stick drilling. Example 2

[0039] Based on Example 1, to address the deformation of the borehole caused by material springback, a component for heating the drill bit 307 (i.e., a conventional electrothermal drill bit) is incorporated. This allows the surface temperature of the drill bit 307 to reach 300-350°C (a lower temperature would require a longer carbonization time, while temperatures exceeding 400°C might ignite the ash; therefore, 300-350°C is the most suitable). When the drilling speed of the drill bit 307 is slow, a lower surface temperature can be selected; when the drilling speed is fast, a higher surface temperature can be selected. Through adjustment, the optimal drilling speed and surface temperature of the drill bit 307 can be obtained. By applying heat during the drilling process of the drill bit 307, a carbonized layer forms on the surface of the drilled borehole, increasing the stability of the drilled structure. Example 3

[0040] like Figure 6 As shown, based on Embodiment 2, to further improve the automation of drilling, a first conveyor 22 for conveying moxa sticks to be drilled is provided on the right side of the workbench 8, and a second conveyor 23 for conveying drilled moxa sticks is provided below the discharge port 14 of the workbench 8. The first conveyor 22 conveys from right to left, and the width of the first conveyor 22 is adapted to the width of the moxa stick. The first conveyor 22 corresponds to the channel formed by the front and rear side baffles 15. The second conveyor 23 conveys from front to back, and the width of the second conveyor 23 is adapted to the width of the discharge port 14, and the second conveyor 23 corresponds to the discharge port 14. Side guard plates 24 are provided on the front and rear sides of the first conveyor 22 and the left and right sides of the second conveyor 23 to prevent the moxa sticks from falling. The conveying speed of the first conveyor 22 and the second conveyor 23 should be adjusted, and a slower conveying speed should be used as much as possible to ensure that the moxa sticks are conveyed smoothly.

[0041] When the automatic drilling device is working, the first conveyor 22 transports the moxa sticks to be drilled from right to left to the right side of the workbench 8. Under the conveying thrust of the first conveyor 22, the two moxa sticks are pushed into the drilling station along the side push plate 15. Then the first conveyor 22 stops conveying and drilling is carried out according to the working process of the automatic drilling device described in Embodiment 1. After the drilling is completed, the moxa sticks falling from the discharge port 14 fall into the second conveyor 23. The second conveyor 23 begins to transport a distance slightly larger than the diameter of one moxa stick from front to back. Example 4

[0042] Based on Example 2, the electric heating drill bit is replaced with one that uses electromagnetic induction to heat the drill bit 307, specifically as follows: Figure 7 , 8 As shown, a cover plate 19 is provided above the front push plate 4. The cover plate 19 has a second through hole 20 for the drill bit 307 to pass through. An electromagnetic induction heater (a commercially available product can be used) is provided inside the cover plate 19. The electromagnetic induction heater includes a coil 21 arranged around the second through hole. When the drill bit 307 passes downward through the coil 21, the drill bit 307 is heated.

[0043] In Examples 1-4, the starting and stopping of the third cylinder 203, motor 303, first cylinder 11, second cylinder 12, fan, first conveyor 22 and second conveyor 23 can all be automated using conventional control methods of the prior art. Those skilled in the art can complete this by conventional debugging. This is not the innovation of this utility model, so it will not be described in detail.

[0044] This invention is applicable not only to drilling holes in moxa sticks, but also to drilling holes in other similar cylindrical materials. Since the positional accuracy requirements for drilling holes in cylindrical moxibustion materials are not very high, the applicability requirements can be met by adjusting or replacing some parts of the automatic drilling device. Specifically, this can be achieved in the following ways:

[0045] When the diameter of the cylindrical moxibustion material to be drilled changes, the dimensions of the drilling station and the distance between the two drill bits 307 need to be adjusted so that the drilling station can just accommodate two parallel cylindrical moxibustion materials, and the axial center lines of the two drill bits 307 coincide with the axial center lines of the two cylindrical moxibustion materials. The dimensions of the drilling station can be adjusted by changing the left-right distance between the first moving baffle 5 and the second moving baffle 6, the front-back distance between the first moving baffle 5 and the front push plate 4, and the front-back distance between the second moving baffle 6 and the front push plate 4. The distance between the two drill bits 307 can be adjusted by changing the distance between the two rotating shafts 306 inside the second housing 302. When the required hole diameter changes, drill bits 307 of different diameters can be replaced according to the required hole diameter.

[0046] The automatic drilling device of this utility model, through the cooperation of the lifting component and the drilling component, realizes the downward drilling and upward reset of the drill bit 307. The drill bit 307 is cleaned in time by blowing air, and the drill bit 307 is heated to achieve carbonization treatment on the surface of the hole while drilling, which helps to maintain the shape of the hole.
