Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic milling cutters, in particular to a micro-textured cutter for ultrasonic milling. Background Art

[0002] A micro-textured cutter is a new type of cutter, which is characterized in that by performing micron-level processing on the cutter surface to form a micro-textured structure and filling some materials in the structure, the cutting performance can be improved and the service life can be extended.

[0003] Ultrasonic milling is a composite machining technology that combines the principles of ultrasonic machining and normal machining. It uses ultrasonic waves to make the cutter vibrate at a vibration frequency of 20 - 50KHz (i.e., 20,000 - 50,000 times per second). The impact acceleration generated by this high-frequency vibration is very large, about 104 - 105 times the gravitational acceleration. When this vibration is combined with the main movement of the machine tool, the cutter will vibrate at a high speed along the cutting direction, so as to first break up the material and then remove it, achieving very efficient material removal.

[0004] However, the existing ultrasonic milling cutters only have a downward cutting edge. When the ultrasonic component drives the ultrasonic milling cutter body to perform up-and-down ultrasonic vibration, there is only a cutting effect when the cutting edge moves downward, resulting in a certain waste of kinetic energy and being not conducive to improving the processing efficiency. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a micro-textured cutter for ultrasonic milling, which solves the problem of kinetic energy waste caused by the traditional ultrasonic milling cutter only having a cutting effect when moving downward.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the utility model provides the following technical solution: A micro-textured cutter for ultrasonic milling, comprising an ultrasonic milling cutter body, a PVD coating, and an alumina coating. One end of the ultrasonic milling cutter body is an alloy milling cutter head. Two first chip removal grooves are provided on the outer cylindrical surface of the alloy milling cutter head. Two secondary chip removal grooves are provided on the outer cylindrical surface of the alloy milling cutter head. A cutting area is formed between the secondary chip removal groove and the first chip removal groove;

[0009] An arc-shaped grinding groove is formed by grinding on the outer surface of the cutting area. An upward cutting edge is formed between the arc-shaped grinding groove and the first chip removal groove, and the upward cutting edge is used for upward cutting during cutting. A downward cutting edge is formed between the arc-shaped grinding groove and the secondary chip removal groove, and the downward cutting edge is used for downward cutting.

[0010] Preferably, two milling cutter inclination angles are ground and formed at one end of the alloy milling cutter head, and an end face grinding edge surface is ground and formed between the two milling cutter inclination angles and the first chip discharge groove.

[0011] Preferably, chip guiding grooves are ground and formed in both of the first chip discharge grooves, and an end face cutting edge is formed between the chip guiding grooves and the end face grinding edge surface, and the end face cutting edge is used for cutting during downward feeding.

[0012] Preferably, a fixing groove for clamping and limiting is formed on the outer surface of one end of the ultrasonic milling cutter body far away from the alloy milling cutter head.

[0013] Preferably, the PVD coating is coated on the whole outer surface of the ultrasonic milling cutter body, and the PVD coating is a physical vapor deposition coating.

[0014] Preferably, an alumina coating is coated on the outer surface of the PVD coating, and the alumina coating is located in the cutting area of the alloy milling cutter head.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present utility model provides a micro-textured tool for ultrasonic milling, which has the following beneficial effects:

[0017] 1. For the micro-textured tool for ultrasonic milling, by arranging the upward cutting edge and the downward cutting edge, when the ultrasonic milling cutter body makes an up-and-down ultrasonic vibration driven by the ultrasonic component while having the normal rotary milling ability of the alloy milling cutter head, the upward cutting edge and the downward cutting edge can make the ultrasonic milling cutter body have a certain cutting force both when going up and when going down, which can greatly improve the cutting efficiency of the alloy milling cutter head and avoid the kinetic energy waste caused by the traditional ultrasonic milling cutter only having a cutting effect when going down.

[0018] 2. For the micro-textured tool for ultrasonic milling, when the ultrasonic component drives the ultrasonic milling cutter body to make an up-and-down ultrasonic vibration and a cutting movement, the downward cutting edge when going up can cut the area cut by the upward cutting edge when going down in the reverse direction, and similarly, the upward cutting edge when going down can also cut the area cut by the downward cutting edge when going up in the reverse direction, which can make the surface of the material after cutting by the alloy milling cutter head have better flatness and smoothness and greatly improve the cutting quality of the alloy milling cutter head.

[0019] 3. For the micro-textured tool for ultrasonic milling, the physical vapor deposition coating arranged can provide a very thin coating with excellent adhesion and wear resistance, which can make the ultrasonic milling cutter body have a strong frictional force when being clamped so that the ultrasonic milling cutter body can be firmly clamped by the chuck, and to a certain extent, avoid the situation of tool slipping.

[0020] 4. The micro-textured tool for ultrasonic milling can provide good anti-adhesion performance through the provided alumina coating, reduce chip adhesion, and is suitable for rough machining and interrupted machining. Moreover, by coating the alumina coating on the outer surface of the first chip removal groove, the alumina coating can be made more difficult to fall off, which increases the durability of the alloy milling cutter head to a certain extent.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-4 , the present invention provides a new technical solution: a micro-textured tool for ultrasonic milling, including an ultrasonic milling cutter body 1, a PVD coating 13, and an alumina coating 14. One end of the ultrasonic milling cutter body 1 is an alloy milling cutter head 2. Two first chip removal grooves 3 are provided on the outer circumferential surface of the alloy milling cutter head 2, and two secondary chip removal grooves 4 are provided on the outer circumferential surface of the alloy milling cutter head 2. A cutting area 5 is formed between the secondary chip removal groove 4 and the first chip removal groove 3;

[0028] The outer surface of the cutting area 5 is ground with an arc-shaped grinding groove 6. An upward cutting edge 7 is formed between the arc-shaped grinding groove 6 and the first chip removal groove 3. The upward cutting edge 7 is used for upward cutting during cutting. A downward cutting edge 8 is formed between the arc-shaped grinding groove 6 and the secondary chip removal groove 4. The downward cutting edge 8 is used for downward cutting.

[0029] Furthermore, by providing the upward cutting edge 7 and the downward cutting edge 8, when the ultrasonic component drives the ultrasonic milling cutter body 1 to perform up-and-down ultrasonic vibration while the alloy milling cutter head 2 has the normal rotary milling ability, the upward cutting edge 7 and the downward cutting edge 8 can enable the ultrasonic milling cutter body 1 to have a certain cutting force both when ascending and descending. This can greatly improve the cutting efficiency of the alloy milling cutter head 2 and avoid the kinetic energy waste caused by the traditional ultrasonic milling cutter only having a cutting effect when descending.

[0030] Furthermore, when the ultrasonic component drives the ultrasonic milling cutter body 1 to perform up-and-down ultrasonic vibration and cutting movement, the downward cutting edge 8 during ascending can perform reverse cutting on the area cut by the upward cutting edge 7 during descending. Similarly, the upward cutting edge 7 during descending can also perform reverse cutting on the area cut by the downward cutting edge 8 during ascending. This can enable the surface of the material after cutting by the alloy milling cutter head 2 to have better flatness and smoothness, and greatly improve the cutting quality of the alloy milling cutter head 2.

[0031] Furthermore, two milling cutter inclination angles 9 are ground at one end of the alloy milling cutter head 2. An end face grinding cutting edge surface 10 is ground between the two milling cutter inclination angles 9 and the first chip removal groove 3.

[0032] Furthermore, chip guiding grooves 11 are ground in both of the two first chip removal grooves 3. An end face cutting edge 15 is formed between the chip guiding grooves 11 and the end face grinding cutting edge surface 10. The end face cutting edge 15 is used for cutting during downward feed.

[0033] Furthermore, a fixing groove 12 for clamping and limiting is provided on the outer surface of the end of the ultrasonic milling cutter body 1 away from the alloy milling cutter head 2.

[0034] Furthermore, a PVD coating 13 is coated on the overall outer surface of the ultrasonic milling cutter body 1. The PVD coating 13 is a physical vapor deposition coating.

[0035] Furthermore, the physical vapor deposition coating can provide a very thin coating with excellent adhesion and wear resistance. This can enable the ultrasonic milling cutter body 1 to have a strong frictional force during clamping so that the ultrasonic milling cutter body 1 can be firmly clamped by the chuck, and to a certain extent, avoid the situation of tool slippage.

[0036] Furthermore, an alumina coating 14 is coated on the outer surface of the PVD coating 13, and the alumina coating 14 is located in the cutting area of the alloy milling cutter head 2.

[0037] Furthermore, the alumina coating can provide good anti-adhesion performance, reduce chip adhesion, and is suitable for rough machining and interrupted machining. By coating the alumina coating 14 on the outer surface of the PVD coating 13, the alumina coating 14 can be made more difficult to fall off, which increases the durability of the alloy milling cutter head 2 to a certain extent.

[0038] Working principle: By providing the upward cutting edge 7 and the downward cutting edge 8, when the ultrasonic component drives the ultrasonic milling cutter body 1 to perform up-and-down ultrasonic vibration while the alloy milling cutter head 2 has the normal rotary milling ability, the upward cutting edge 7 and the downward cutting edge 8 can make the ultrasonic milling cutter body 1 have a certain cutting force both when it moves upward and downward. This can greatly improve the cutting efficiency of the alloy milling cutter head 2 and avoid the kinetic energy waste caused by the traditional ultrasonic milling cutter only having a cutting effect when moving downward.

[0039] Moreover, when the ultrasonic component drives the ultrasonic milling cutter body 1 to perform up-and-down ultrasonic vibration and cutting movement, the downward cutting edge 8 during the upward movement can perform reverse cutting on the area cut by the upward cutting edge 7 during the downward movement. Similarly, the upward cutting edge 7 during the downward movement can also perform reverse cutting on the area cut by the downward cutting edge 8 during the upward movement. This can make the surface of the material after cutting by the alloy milling cutter head 2 have better flatness and smoothness, and greatly improve the cutting quality of the alloy milling cutter head 2.

[0040] The physical vapor deposition coating provided can provide a very thin coating with excellent adhesion and wear resistance. This can make the ultrasonic milling cutter body 1 have a strong frictional force when being clamped, so that the ultrasonic milling cutter body 1 can be firmly clamped by the chuck, and to a certain extent, avoid the situation of tool slippage.

[0041] The alumina coating provided can provide good anti-adhesion performance, reduce chip adhesion, and is suitable for rough machining and interrupted machining. By coating the alumina coating 14 on the outer surface of the PVD coating 13, the alumina coating 14 can be made more difficult to fall off, which increases the durability of the alloy milling cutter head 2 to a certain extent.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
