Description

Technical Field

[0001] This utility model relates to the field of wire saws, and in particular to a wire saw for cutting fan blades. Background Technology

[0002] With the rapid development of the wind power industry, a large number of early-installed wind turbine blades are reaching the end of their service life. These discarded fan blades (i.e., wind turbine blades) are large and complex in structure, resulting in extremely high overall transportation costs. In the past, they were often disposed of on-site or in landfills, causing serious resource waste and environmental pollution. To reduce transportation costs and achieve resource utilization, the current common practice is to cut the discarded blades into smaller segments on-site before transportation. However, traditional cutting equipment, especially the widely used single-wire saw, has significant drawbacks in this application scenario: a single-wire saw can only make one kerf at a time. To obtain a piece of sheet material of a certain thickness, it is necessary to first make the first kerf, then precisely move the worktable (or the saw itself) by the thickness of the sheet material, and then make a second cut.

[0003] Existing technology CN202110503398.0 discloses a single-wire double-blade wire saw cutting mechanism, including a cutting wire and two sets of guide wheel assemblies. The cutting wire is arranged in a ring within the grooves of the two sets of guide wheel assemblies, and the two sets of guide wheel assemblies are rotated in opposite directions and closer to each other to bend the cutting wire into two rows of two-fold lines. The bends are guided by steering wheel assemblies to tension the portion of the cutting wire located between the two sets of rotated guide wheel assemblies, forming two rows of cutting segments. Although this solution can achieve double-blade cutting with only a single cutting wire, it still has the following problems:

[0004] 1. The spacing between the two rows of cutting sections is preset and fixed by the rotation angle of the guide wheel assembly and the position of the steering wheel. Once the equipment is assembled, its cutting spacing cannot be dynamically adjusted according to the actual thickness of the material to be cut (such as the plate thickness required for different blade parts). This results in the equipment being only suitable for a single or very limited range of cutting tasks, with poor versatility.

[0005] 2. The fan blade cutting process generates a lot of heat, requiring an efficient cooling system. Existing cooling methods are often set up independently of the cutting area, making coolant recovery difficult. In particular, when large workpieces are cut through the cutting process, the efficiency of collecting and recycling coolant in the lower area is not high, which increases cooling costs and environmental pressure. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a wire saw for cutting fan blades, which can achieve efficient synchronous double-blade cutting, flexibly adapt to different cutting spacing requirements, and has the ability to efficiently recycle and reuse coolant. This is of great significance for the economical and environmentally friendly recycling and disposal of waste fan blades.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A wire saw for cutting fan blades is provided, comprising: a lifting frame, a cutting frame, a cooling device, a mounting base, and a cutting wire; the lifting frame is mounted on the mounting base, and the cutting frame includes a main cutting frame and a secondary cutting frame, which are symmetrically arranged on both sides of the lifting frame and can move up and down along the lifting frame;

[0009] The cutting line is arranged horizontally in a ring around the main cutting frame and the slave cutting frame. Drive rollers for transporting workpieces are spaced apart on the mounting base between the main and slave cutting frames. The cooling device includes a storage tank, a circulating pump, and an outlet pipe. The storage tank is mounted on the mounting base and located directly below the cutting line, with its upper surface flush with the upper surface of the drive rollers. The outlet pipe is positioned on the cutting frame and the lifting frame corresponding to the cutting line. The two ends of the circulating pump are connected to the storage tank and the outlet pipe, respectively.

[0010] It should be noted that the mounting base serves as the basic support, and the lifting frame is fixed to the mounting base by bolts or welding to form the main support structure of the equipment. This ensures that the lifting frame remains stable during the cutting process and avoids deviations in cutting accuracy due to vibration. The main and slave cutting frames cooperate with the guide rails of the lifting frame through sliders, and are driven to rise and fall synchronously by a lifting device (such as a stepper motor driving a lead screw), achieving precise adjustment of the vertical position of the cutting line to meet the cutting needs of fan blades of different thicknesses. In the cooling device, the liquid storage tank is located directly below the cutting line and its upper end is flush with the transmission roller, facilitating the flow and recovery of coolant by gravity. The circulation pump pressurizes the coolant in the storage tank and sprays it to the vicinity of the cutting line through the outlet pipe to cool it down, forming a closed loop. The multi-directional outlet pipes ensure cooling of the entire cutting line area, preventing wire annealing or workpiece deformation caused by high temperatures, while also flushing away debris. The coolant recovery rate is high, reducing consumption and pollution.

[0011] Preferably, the liquid storage tank includes a receiving box, a water storage tank, and a balancing pipe. The receiving box is located on a support base directly below the cutting line. The water storage tanks are symmetrically arranged on both sides of the receiving box and are connected to the receiving box through connecting pipes. The water storage tanks are connected to each other through balancing pipes, which are connected to the lower outer side of the water storage tanks.

[0012] It should be noted that the receiving tank is located directly below the cutting line, directly collecting the coolant and debris dripping during the cutting process. The two water tanks on both sides are connected to the receiving tank via connecting pipes. When the liquid level in the receiving tank rises, the coolant flows through the connecting pipes into the symmetrically arranged water tanks, thus expanding the storage capacity. The balance pipe at the lower outer end of the water tanks ensures that the liquid level in the two water tanks is consistent, preventing the equipment's center of gravity from shifting due to uneven liquid storage on one side. Compared to traditional single liquid tanks, this design effectively increases the liquid storage capacity. The balance pipe avoids the risk of the equipment tilting due to liquid imbalance. At the same time, the interconnected structure enables efficient recycling of the coolant, reducing the frequency of coolant replenishment and waste, and lowering the cooling cost and equipment maintenance difficulty of the cutting operation.

[0013] Preferably, the receiving box is provided with a conveying roller flush with the drive roller, the conveying rollers are spaced apart in the receiving box directly below the cutting line along the workpiece transport direction, and a workpiece support platform is provided between adjacent conveying rollers, the workpiece support platform is provided with drainage holes evenly distributed.

[0014] It should be noted that the technical advantages are as follows: the flush design of the conveyor rollers and drive rollers ensures that the workpiece passes smoothly through the cutting area, avoiding swaying due to support interruption; the spaced conveyor rollers and the support platform with drainage holes maintain the stability of workpiece conveying and achieve efficient coolant recovery and debris filtration; compared with a structure without conveyor roller support, this design can reduce workpiece deformation during cutting and improve cutting accuracy; the drainage hole design prevents coolant accumulation from affecting workpiece support, while reducing the risk of equipment failure caused by debris accumulation, reducing maintenance frequency, and improving equipment operating efficiency.

[0015] Preferably, the cutting line is arranged in a ring horizontally within the grooves of the driving and driven wheel sets at the lower ends of the main and secondary cutting frames. The driving and driven wheel sets are each composed of multiple transmission wheels of different diameters arranged side by side in the vertical direction, and the center lines of the transmission wheels in the same wheel set coincide, and the transmission wheels on the same horizontal plane have the same diameter.

[0016] It should be noted that the driving wheel set is driven to rotate by the power unit, and drives the cutting wire to form a circular horizontal motion through the wire groove. The driven wheel set supports the cutting wire and maintains its tension. The transmission wheels of different diameters are arranged vertically, so that the cutting wire can travel around the transmission wheels of different diameters in the same wheel set. The vertically arranged transmission wheels of different diameters form a multi-layer wire groove structure, which keeps the cutting wire under stable tension in the circular motion. The transmission wheels on the same horizontal plane have the same diameter to ensure that the height of the cutting wire on both sides is consistent, thereby changing the horizontal cutting distance of the cutting wire by using the diameter difference.

[0017] Preferably, it also includes a tensioning wheel, which is set on the cutting frame corresponding to the cutting line and can tension the cutting line. The tensioning wheel can also switch the corresponding cutting line on the corresponding transmission wheel, and adjust the spacing between the cutting lines on both sides by changing the combination of transmission wheel diameters.

[0018] It should be noted that the mechanical structure applies tension to the cutting wire, ensuring it remains taut during circular motion. Simultaneously, the cutting wire can be switched between different diameter drive wheels in the driving and driven wheel sets. Utilizing the circumference difference between these diameter wheels, the horizontal position of the cutting wires on both sides of the main and driven cutting frames is adjusted, thereby changing the spacing between the cutting wires. In short, the tensioning wheel maintains the cutting wire tension in real time, preventing cutting vibration or decreased accuracy due to slack. Furthermore, by switching the combination of drive wheel diameters, the cutting spacing is dynamically adjusted, adapting to the cutting needs of workpieces of varying thicknesses without disassembling the equipment. This completely solves the defect of fixed cutting spacing in existing technologies, giving the equipment flexible adaptability to various working conditions. The cutting spacing can be quickly adjusted to meet the thickness requirements of different parts of the fan blades. At the same time, the tensioning function extends the service life of the cutting wire, reduces equipment failures caused by insufficient tension, and improves the efficiency and economy of waste blade recycling and cutting.

[0019] Preferably, the lifting frame includes a gantry frame and a lifting device. The lifting devices are symmetrically installed in the receiving slots of the two side columns of the gantry frame. The main cutting frame and the secondary cutting frame are both set on the gantry frame through the lifting devices and are lifted synchronously through the lifting devices.

[0020] It should be noted that the rigid structure of the gantry frame provides stable support for the cutting machine frame, and the symmetrically arranged lifting devices ensure that the main and slave cutting frames move synchronously and accurately adjust the vertical position of the cutting line. Compared with the asymmetrical lifting structure, this design eliminates the risk of cutting deviation caused by asynchronous lifting of the two cutting frames. It can adapt to the cutting needs of fan blades of different thicknesses and improve the equipment's versatility for workpiece specifications. At the same time, the combination of the gantry frame and the lifting device enhances the overall structural stability of the equipment, reduces vibration during the cutting process, and ensures cutting accuracy.

[0021] Preferably, the upper end of the gantry frame is provided with a support beam, and multiple coolant outlet pipes are spaced apart along the length of the support beam, with the outlet of the outlet pipes vertically downward and aligned with the cutting line.

[0022] It should be noted that the support beam serves as the mounting carrier for the outlet pipes and is connected to the output end of the circulation pump via a pipeline. The circulation pump pressurizes the coolant in the storage tank and delivers it to the outlet pipes, which spray it from the vertically downward outlets onto the cutting area of ​​the cutting line. Multiple outlet pipes are distributed along the length of the beam, covering the entire working length of the cutting line. The vertically downward spray angle ensures that the coolant directly acts on the area where the cutting heat is concentrated, achieving precise cooling.

[0023] Preferably, the lifting device includes a stepper motor, a synchronous transmission mechanism, a lifting nut seat, and a lifting screw; the lifting screw is vertically arranged in the receiving groove, its upper end is fixed to the top of the column by a bearing seat, and its lower end is supported at the bottom of the column by a deep groove ball bearing; the stepper motor is installed on the top crossbeam of the portal frame, and its output shaft drives the lifting screws on both sides to rotate synchronously through the synchronous transmission mechanism; the lifting nut seat is threadedly connected to the lifting screw and is arranged in the receiving groove, the main cutting frame and the slave cutting frame are fixed on the corresponding lifting nut seat, and the main cutting frame and the slave cutting frame are driven to move synchronously up and down along the lifting screw axis by the up and down movement of the lifting nut seat.

[0024] It should be noted that the lifting screw is vertically installed in the receiving groove of the portal frame column. The upper end is fixed to the top of the column by a bearing seat, and the lower end is supported by a deep groove ball bearing to reduce rotational friction. The stepper motor is installed on the top crossbeam of the portal frame. Its output shaft drives the lifting screws on both sides to rotate synchronously through a synchronous transmission mechanism (such as a connecting shaft or gear set). The lifting nut seat, which is threaded to the screw, moves up and down along the screw axis in the receiving groove, thereby driving the main cutting frame and the slave cutting frame, which are fixed on the nut seat, to rise and fall synchronously. The design solves the problem of asynchrony on both sides that is easy to occur in traditional lifting structures. It can control the lifting error of the cutting frame to within 0.1mm, which is suitable for precise cutting of fan blades of different thicknesses. At the same time, the modular lifting device facilitates maintenance and replacement, and the self-locking characteristic of the threaded drive can prevent the cutting frame from sliding down due to gravity during the cutting process, improving the safety and reliability of the equipment operation.

[0025] Preferably, a guide rail is provided at the bottom of the receiving groove along the axial direction of the column, the guide rail is symmetrically arranged on both sides of the lifting screw, and a guide block is correspondingly provided on the lifting nut seat.

[0026] It should be noted that the guide rail is fixed to the bottom of the receiving groove and extends along the column axis. The guide block on the lifting nut seat is embedded in the guide rail groove. When the lifting nut seat moves up and down under the drive of the lifting screw, the guide block slides along the guide rail, restricting the lateral displacement of the nut seat and allowing it to move only along the column axis. This guide structure eliminates the lateral sway during the operation of the lifting device, controls the lifting error of the cutting frame to a very small range, ensures the accuracy of the vertical position of the cutting line, reduces the wear of mechanical parts caused by off-center load, extends the service life of the equipment, and provides stable mechanical support for the high-precision cutting of the fan blades.

[0027] The beneficial effects of this utility model are:

[0028] This utility model provides a wire saw for cutting fan blades. Through the coordinated design of the lifting frame, cutting frame, and cooling device, it achieves efficient synchronous double-blade cutting. The cutting line can be switched between different diameter transmission wheels by a tensioning dial, dynamically adjusting the spacing between the two cutting lines to flexibly adapt to the cutting needs of workpieces of different thicknesses. The cooling device has a liquid storage tank flush with the transmission roller and adopts a receiving box, water storage tank, and balance pipe structure. With the help of a circulating pump and multi-directional liquid outlet pipes, it achieves efficient recovery and recycling of coolant, reducing consumption and pollution. The transmission roller works in conjunction with the conveying roller in the receiving box and the workpiece support platform with drainage holes to ensure stable workpiece transport and cutting, improve cutting accuracy, and reduce maintenance frequency. The gantry frame works in conjunction with the lifting device, guide rail and guide block structure to ensure synchronous lifting of the cutting frame and equipment stability, reduce vibration, and ensure cutting accuracy. It effectively solves the problems of low cutting efficiency, non-adjustable spacing, and difficulty in cooling recovery of traditional equipment, and is of great significance for the economical and environmentally friendly treatment of waste fan blades.

[0039] Example 1

[0041] The cutting line 5 is arranged horizontally in a ring around the main cutting frame 21 and the slave cutting frame 22. The mounting base 4 between the main cutting frame 21 and the slave cutting frame 22 is provided with transmission rollers 6 for transporting workpieces at intervals. The cooling device 3 includes a liquid storage tank 31, a circulation pump 32 and a liquid outlet pipe 33. The liquid storage tank 31 is set on the mounting base 4 and located directly below the cutting line 5. The upper end face of the liquid storage tank 31 is flush with the upper end face of the transmission rollers 6. The liquid outlet pipe 33 is set on the cutting frame 2 and the lifting frame 1 corresponding to the cutting line 5. The two ends of the circulation pump 32 are connected to the liquid storage tank 31 and the liquid outlet pipe 33, respectively.

[0042] The liquid storage tank 31 includes a receiving box 311, a water storage tank 312, and a balance pipe 313. The receiving box 311 is located on a support base directly below the cutting line 5. The water storage tanks 312 are symmetrically arranged on both sides of the receiving box 311 and are connected to the receiving box 311 through connecting pipes. The water storage tanks 312 are connected to each other through the balance pipe 313, which is connected to the lower outer side of the water storage tank 312.

[0043] The receiving box 311 is provided with a conveying roller 314 that is flush with the transmission roller 6. The conveying rollers 314 are spaced apart in the receiving box 311 directly below the cutting line 5 along the workpiece transport direction, and a workpiece support platform 315 is provided between adjacent conveying rollers 314. Drainage holes are evenly distributed on the workpiece support platform 315.

[0044] The cutting line 5 is arranged in a ring horizontally within the grooves of the driving wheel set 211 and the driven wheel set 221 at the lower end of the main cutting frame 21 and the driven wheel set 221. The driving wheel set 211 and the driven wheel set 221 are each composed of multiple transmission wheels of different diameters arranged in parallel along the vertical direction, and the center lines of the transmission wheels in the same wheel set coincide, and the transmission wheels on the same horizontal plane have the same diameter.

[0045] It also includes a tensioning wheel 7, which is set on the cutting frame 2 corresponding to the cutting line 5 and can tension the cutting line 5. The tensioning wheel 7 can also move the corresponding cutting line 5 to switch on the corresponding transmission wheel, and adjust the spacing between the two cutting lines 5 by changing the combination of the diameters of the transmission wheels.

[0046] The lifting frame 1 includes a gantry frame 11 and a lifting device 12. The lifting device 12 is symmetrically installed in the receiving slots 111 of the two side columns of the gantry frame 11. The main cutting frame 21 and the secondary cutting frame 22 are both set on the gantry frame 11 through the lifting device 12 and are lifted and lowered synchronously through the lifting device 12.

[0047] The upper end of the portal frame 11 is provided with a support beam 112, and a plurality of coolant outlet pipes 33 are provided at intervals along the length direction on the support beam 112, and the outlet of the outlet pipes 33 is vertically downward aligned with the cutting line 5.

[0048] The lifting device 12 includes a stepper motor 121, a synchronous transmission mechanism 122, a lifting nut seat 123, and a lifting screw 124. The lifting screw 124 is vertically arranged in the receiving groove 111, with its upper end fixed to the top of the column by a bearing seat and its lower end supported at the bottom of the column by a deep groove ball bearing. The stepper motor 121 is mounted on the top crossbeam of the portal frame 11, and its output shaft drives the lifting screws 124 on both sides to rotate synchronously through the synchronous transmission mechanism 122. The lifting nut seat 123 is threadedly connected to the lifting screw 124 and is arranged in the receiving groove 111. The main cutting frame 21 and the secondary cutting frame 22 are fixed on the corresponding lifting nut seats 123, and the main cutting frame 21 and the secondary cutting frame 22 are driven to move synchronously up and down along the lifting screw axis by the up and down movement of the lifting nut seats 123.

[0049] The bottom of the receiving groove 111 is provided with a guide rail 13 along the column axis. The guide rail 13 is symmetrically arranged on both sides of the lifting screw 124. The lifting nut seat 123 is provided with a corresponding guide block 14.

[0050] The working principle and usage method of a wire saw for cutting fan blades in this embodiment are as follows:

[0051] This embodiment provides a wire saw for cutting fan blades. A mounting base 4 serves as the basic support structure. A portal frame 11, shaped like a "gate," is fixed to the base by bolts or welding. The two side columns have internal receiving grooves 111, within which lifting screws 124 are vertically installed. The upper end of the screw is fixed to the top of the column via a bearing seat, and the lower end is supported at the bottom of the column by a deep groove ball bearing, forming a rotating support structure. A stepper motor 121 is mounted on the top beam of the portal frame 11. Its output shaft drives the lifting screws 124 on both sides to rotate synchronously via a synchronous transmission mechanism 122 composed of a synchronous belt or gear set. A guide block 14 is fixed on a lifting nut seat 123 threadedly connected to the screw. This guide block 14 is embedded in a guide rail 13 groove symmetrically arranged along the column axis at the bottom of the receiving groove 111. When the screw rotates, the nut seat moves up and down along the guide rail 13 axis, causing the main cutting frame 21 and the secondary cutting frame 22 fixed thereon to rise and fall synchronously. The master and slave cutting frames 22 are symmetrically arranged frame structures, with a drive wheel set 211 and a slave wheel set 221 respectively installed at their lower ends. Each set consists of multiple transmission wheels of different diameters arranged in parallel along the vertical direction. The center lines of the transmission wheels in the same wheel set coincide, and the transmission wheels on the same horizontal plane have the same diameter. The cutting line 5 is horizontally wound in a ring in the groove of the wheel sets on both sides. The drive wheel set 211 is driven to rotate by a power motor, which drives the cutting line 5 to form a horizontal ring motion. A tensioning wheel 7 is set on the cutting frame 2 corresponding to the cutting line 5. This wheel can switch the cutting line 5 on different diameter transmission wheels through a lever or hydraulic mechanism, and change the horizontal distance between the two cutting lines 5 by using the diameter difference. Drive rollers 6 are spaced apart on the mounting base 4 between the master and slave cutting frames 22. The rollers are driven to rotate by a motor. The receiving box 311 is located directly below the cutting line 5. Conveyor rollers 314 are spaced apart inside the box at the same level as the drive rollers 6. A workpiece support platform 315 with drainage holes is provided between adjacent conveyor rollers 314. When the workpiece is conveyed to the cutting area by the drive rollers 6, the conveyor rollers 314 and the support platform 315 jointly support the workpiece. In the cooling device 3, the two sides of the receiving box 311 are connected to symmetrically arranged water storage tanks 312 through connecting pipes. The lower outer side of the water storage tanks 312 is connected by a balance pipe 313. One end of the circulating pump 32 is connected to the liquid storage tank 31 (composed of the receiving box 311 and the water storage tank 312), and the other end is connected to the outlet pipe 33 on the crossbeam 112 of the cutting machine frame 2, the lifting frame 1 and the gantry frame 11 through a pipe. The outlet pipes 33 on the crossbeam are arranged at intervals along the length direction, and the outlet is vertically downward aligned with the cutting line 5. The circulating pump 32 pressurizes the coolant in the liquid storage tank 31 and sprays it to the cutting area through the outlet pipe 33 to cool it down. The coolant carries the debris into the receiving box 311 and is diverted to the water storage tank 312 through the connecting pipe. The balance pipe 313 maintains the liquid level on both sides to be consistent, forming a cooling cycle.

[0052] During use, the mounting base 4 is fixed to a flat ground with anchor bolts, and the portal frame 11 is fixed to the mounting base 4 by bolts or welding, ensuring that the columns on both sides of the portal frame 11 are perpendicular to the ground; check the installation status of the lifting screw 124 in the column receiving groove 111: the upper end of the screw is fixed to the top of the column by a bearing seat, and the lower end is supported at the bottom of the column by a deep groove ball bearing, ensuring that the screw can rotate flexibly; the guide rail 13 at the bottom of the receiving groove 111 is symmetrically installed along the column axis and cooperates with the guide block 14 on the lifting nut seat 123 to ensure that there is no lateral offset when the nut seat moves; then adjust the vertical position of the cutting line 5: according to the thickness of the blade to be cut, start the stepper motor 121 on the top crossbeam of the portal frame 11, and the electric... The machine output shaft drives the lifting screws 124 on both sides to rotate synchronously via a synchronous transmission mechanism 122 composed of a synchronous belt or gear set. The lifting nut seat 123, which is threaded to the screw, moves up and down along the column axis under the guidance of the guide block 14 and the guide rail 13, driving the main cutting frame 21 and the driven cutting frame 22, which are fixed to the nut seat, to rise and fall synchronously, so that the cutting line 5 is adjusted to a suitable height. Then, the cutting spacing is adjusted: observe the required plate thickness of the part of the blade to be cut, operate the tensioning wheel 7 (lever type or hydraulic drive) on the cutting frame 2, and switch the cutting line 5 between the drive wheel set 211 and the driven wheel set 221 with different diameter transmission wheels. Since the transmission wheels on the same horizontal plane have the same diameter, by selecting the same diameter... The transmission wheel assembly carries the cutting line 5, and the horizontal spacing between the two cutting lines 5 is changed by the diameter difference to complete the spacing setting and equipment modulation; then the fan blades are placed horizontally on the transmission rollers 6 between the main cutting frame 21 and the cutting frame 22, with the front end of the blades extending to the conveying rollers 314 in the receiving box 311; the surfaces of the transmission rollers 6 and the conveying rollers 314 are made of anti-slip rubber material and are driven by a motor to rotate synchronously to ensure smooth blade conveying; the workpiece support platform 315 between adjacent conveying rollers 314 is fixed to the receiving box 311 by bolts, and the drainage holes on the platform allow the coolant to drip smoothly; the circulation pump 32 is turned on, and the coolant (such as water-based cutting fluid) in the storage tank 31 is transported to the cutting machine through the pipeline. The liquid outlet pipe 33 on the support beam 112 is supported by the frame 2, the lifting frame 1, and the gantry frame 11. At the same time, the drive wheel assembly 211 is driven by a power motor (such as a servo motor) to rotate at high speed, driving the annular cutting line 5 to make horizontal circular motion. The lifting device 12 drives the main cutting frame 21 to move downward from the cutting frame 22 to start cutting. After cutting, the power motor and the circulating pump 32 are turned off, and the cut leaf fragments are removed from the transmission roller 6. The drain valve at the bottom of the receiving box 311 is opened to clean the settled debris. The coolant level in the water tank 312 is checked. If it is lower than the warning line, it is added through the replenishment port. If necessary, the coolant is replaced. Finally, the equipment surface is wiped to ensure that there is no oil or debris residue and the equipment is kept clean.
