Description

Technical Field

[0001] This utility model relates to the field of CNC cutting tool technology, specifically a wear-resistant polydiamond CNC milling cutter. Background Technology

[0002] CNC cutting tools refer to cutting tools used on CNC machine tools. These tools are controlled by computer programs to achieve high-precision and high-efficiency cutting. CNC cutting tools play an important role in modern manufacturing and are widely used in metal processing, plastic molding, and wood processing. CNC milling cutters are cutting tools used for milling on CNC milling machines. They typically have multiple cutting edges and can be used to process workpieces made of different materials such as metal, plastic, and wood. The design and materials of CNC milling cutters enable them to effectively remove material at high speeds, forming the desired shape and surface quality.

[0003] In existing technologies, during the machining of slots using CNC milling cutters, metal chips tend to accumulate on the cutting edge of the cutter. If these chips are not cleaned promptly, friction will occur between the cutter and the chips, increasing friction and causing wear on the cutting edge, thus reducing the wear resistance of the CNC milling cutter. Currently, the common method for cleaning chips is to manually blow them off the tool using external compressed air. However, this method does not allow for cleaning of the tool during the cutting process, and metal chips will still accumulate on the cutting edge of the CNC milling cutter, causing wear. Therefore, a wear-resistant polydiamond CNC milling cutter is proposed to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a wear-resistant polydiamond CNC milling cutter, which has the advantage of good wear resistance. It solves the problem that metal chips still accumulate on the cutting edge of the CNC milling cutter due to the inability to clean the tool during the cutting process, and the friction between the metal chips and the cutting edge causes wear to the CNC milling cutter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant polydiamond CNC milling cutter, comprising a cutter body, the cutter body comprising a cutter sleeve, a cutter shank mounted on the cutter sleeve, and a cutter head disposed on the cutter shank, the cutter head having a cutting edge for cutting operations, and the cutting edge having a wear-resistant mechanism for reducing wear.

[0006] The wear-resistant mechanism includes a cleaning component and a connecting component;

[0007] The cleaning assembly includes a cleaning hole on the cutting edge, a cavity formed on the tool holder, and a liquid flow channel connected to the cavity and located on the tool holder.

[0008] Furthermore, the output end of the liquid flow channel is connected to the cleaning hole.

[0009] Furthermore, the longitudinal cross-sectional shape of the cavity is trapezoidal.

[0010] Furthermore, the tool holder has a through hole for the tool shank to pass through, and the through hole is interference-fitted with the tool shank.

[0011] Furthermore, the connecting assembly includes a sealing connector mounted on the tool holder, a pressure boosting valve for increasing liquid pressure mounted on the sealing connector, and a sealing ring for improving sealing performance.

[0012] Furthermore, the sealing connector is provided with an internal thread, and the sealing connector is connected to an external liquid inlet pipe.

[0013] Furthermore, the sealing ring fits against the inner wall of the sealing connection seat.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This wear-resistant polydiamond CNC end mill incorporates a cavity, a cleaning hole, a liquid flow channel, a pressurizing valve, and a sealing connection seat. During machining, pressurized water or cutting fluid flows through the liquid flow channel to the cleaning hole, where it sprays out to clean the metal chips accumulated on the cutting edge. This timely flushing away of the metal chips prevents friction between the CNC end mill and the metal chips, reducing wear on the cutting edge and thus improving the wear resistance and service life of the CNC end mill. It solves the problem of metal chips accumulating on the cutting edge of the CNC end mill even when the tool cannot be cleaned during cutting, causing wear due to friction between the metal chips and the cutting edge.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-2 The wear-resistant polydiamond CNC milling cutter in this embodiment has the advantage of good wear resistance.

[0024] In this embodiment, a wear-resistant polydiamond CNC milling cutter includes a cutter body 1. The cutter body 1 includes a cutter sleeve 2, a cutter shank 3 mounted on the cutter sleeve 2, and a cutter head 4 disposed on the cutter shank 3. The cutter head 4 is provided with a polydiamond coating, which can improve the wear resistance and heat resistance of the CNC milling cutter, reduce friction, and extend the life of the CNC milling cutter. A cutting edge 5 for cutting is formed on the cutter head 4, and a wear-resistant mechanism 6 for reducing wear is provided on the cutting edge 5.

[0025] The wear-resistant mechanism 6 includes a cleaning component and a connecting component.

[0026] The cleaning assembly includes a cleaning hole 601 provided on the cutting edge 5, a cavity 602 formed on the tool holder 3, and a liquid flow channel 603 connected to the cavity 602 and located on the tool holder 3.

[0027] It should be noted that the medium in the liquid flow channel 603 can be cutting fluid or water, as long as it can wash away the metal chips accumulated on the cutting edge 5. At the same time, the liquid in the liquid flow channel 603 can also cool down the CNC milling cutter, further reducing the wear of the CNC milling cutter.

[0028] The tool holder 2 has a through hole for the tool shank 3 to pass through. The through hole and the tool shank 3 are interference fit. In the process of using the polydiamond CNC milling cutter, first insert the tool shank 3 into the through hole on the tool holder 2, and then lock the tool holder 2.

[0029] Please see Figure 3-5 In order to reduce the wear of polydiamond CNC milling cutters, the wear-resistant mechanism 6 in this embodiment includes a cleaning component and a connecting component.

[0030] The cleaning assembly includes a cleaning hole 601 provided on the cutting edge 5, a cavity 602 formed on the tool holder 3, and a liquid flow channel 603 connected to the cavity 602 and located on the tool holder 3.

[0031] The output end of the liquid flow channel 603 is connected to the cleaning hole 601.

[0032] The longitudinal cross-sectional shape of cavity 602 is trapezoidal.

[0033] The connecting assembly includes a sealing connector 604 mounted on the tool holder 3, a pressure boosting valve 605 for increasing liquid pressure mounted on the sealing connector 604, and a sealing ring 606 for improving sealing performance provided on the sealing connector 604.

[0034] The pressure boosting valve 605 is a common valve body in the prior art. In this application, it plays a role in pressurizing, increasing the pressure of the liquid flowing through the sealing connection seat 604, thereby enabling the metal chips accumulated on the cutting edge 5 to be quickly flushed away.

[0035] The sealing connector 604 is provided with internal threads and is connected to the external liquid inlet pipe.

[0036] It should be noted that the external inlet pipe is connected to the output end of the delivery pump, and the cutting fluid is then delivered by the delivery pump to the sealing connection seat 604. The internal thread on the sealing connection seat 604 facilitates connection.

[0037] In actual use, the cutting fluid is delivered by the delivery pump to the inlet pipe at its output end, and then reaches the sealing connection seat 604. The cutting fluid then enters the cavity 602, and then reaches the cleaning hole 601 through the liquid flow channel 603. Finally, the cutting fluid is sprayed out from the cleaning hole 601 and sprayed onto the cutting edge 5, washing away the metal debris accumulated on the cutting edge 5.

[0038] The sealing ring 606 fits against the inner wall of the sealing connector 604. In this application, the sealing ring 606 plays the role of improving the sealing performance of the connection between the sealing connector 604 and the inlet pipe.

[0039] The working principle of the above embodiments is as follows:

[0040] When using a polydiamond CNC milling cutter for cutting, in order to prevent metal chips from accumulating on the cutting edge 5, the sealing connector 604 is connected to the inlet pipe of the external pump before cutting. The cutting fluid enters the cavity 602 through the sealing connector 604, and then reaches the cleaning hole 601 through the liquid flow channel 603. Finally, the cutting fluid is sprayed out from the cleaning hole 601 and sprayed onto the cutting edge 5, washing away the metal chips accumulated on the cutting edge 5 and preventing metal chips from accumulating on the cutting edge 5. At the same time, the sprayed cutting fluid can also cool the cutter head 4 and the cutting edge 5, further reducing the wear of the polydiamond CNC milling cutter.
