Cutter machining method and grinder for grinding cutter

Abstract

The invention relates to a cutter grinding machine, which comprises a machine station, a grinding barrel, a drive motor and a holding mechanism, wherein the grinding barrel is rotatably arranged on the machine station, and grinding materials can be put in the grinding barrel; the drive motor can drive the grinding barrel to rotate; the holding mechanism is combined to the machine station, arranged above the grinding barrel, and can be used for holding a plurality of cutters and ensuring the cutters are put into the grinding barrel to auto-rotate, thus the surfaces of the cutters can be ground to be smooth, and the grinding quality is more stable.

Description

technical field [0001] The invention relates to cutting tool processing, in particular to a grinding machine for grinding cutting tools. Background technique [0002] see Figure 11 As shown, it is a flow block diagram of a generally known cutting tool processing method. The main method is to first mill a blank to produce a tool with a cutting edge and a chip removal groove, and then harden the milled tool by sputtering to increase the hardness of the tool. [0003] see Figure 12 As shown, the surface of the milled tool 1 has several fine and sharp cuts 10 , which are produced when the milling cutter is milling, and a recess 11 is formed between the sharp cuts 10 . [0004] see Figure 13 As shown, it can be seen that the milled tool 1 is hardened by sputtering, and a hardened layer 12 will be plated on the surface of the tool 1 . The hardened layer 12 is very thin, so it cannot fill the recesses 11 between the sharp cuts 10 , and the surface of the cutting tool 1 will ...

AI Technical Summary

Problems solved by technology

The hardened layer 12 is very thin, so it cannot fill the recesses 11 between the sharp cuts 10, and the surface of the cutting tool 1 will still appear uneven after being hardened.

[0005] The uneven surface of the tool will increase the friction resistance and make the cutting and chip removal less smooth, which will make the tool prone to heat accumulation and collapse, and will affect the cutting effect

Therefore, its service life is short and the cutting efficiency is also poor, and because of the increasingly sophisticated milling and cutting requirements of 3c industrial computers (Computer), communications (Communications) and consumer electronics (Consumer-Electronics r), It is becoming more and more important to solve the unevenness of the tool surface
