According to the principle of cutting, the cutting material of the engraving machine depends on the rotational speed (ie, cutting speed) of the cutting edge of the cutting tool. The higher the linear speed, the greater the cutting force and the better the cutting effect. But everything is dialectical, the tool itself is a metal material, it will wear in the cutting and the material to be worn to cause wear, and often the higher the line speed, the faster the wear, which is the most basic cause of wear . So, what happened to the situation where the engraving machine tool wears out? Can be resolved from the following aspects:
1. The installation of the tool should ensure that the tool holder is clean and free from foreign matter, ensuring the installation accuracy of the tool;
2. When selecting a tool, use a tool with good rigidity (large diameter or shank diameter) as much as possible;
3, when the tool is installed, the hanging length should be as short as possible;
4. When the tool starts to be used, it should be first run at a low speed, and the speed is generally controlled at 50% of the normal speed;
5. When rough machining, crush milling should be adopted as much as possible;
6, in the process of processing, in the event of increased vibration, should be suspended in a timely manner to reduce the speed, speed;
7, the use of cutting fluid, adequate cooling, lubrication, can not be filled or closed midway;
8, promptly clear the cutting area of ​​the chip.
Experiments show that the cutting line speed is the main cause of tool wear, and controlling the cutting line speed will improve the degree of tool wear. Specifically, for a certain machining material, the engraving machine uses a carbide tool, and the cutting wear of the tool is limited within a range of “a certain linear speedâ€. When this range is exceeded, the tool wear is quite large! That is to say, for all kinds of processed materials, there is a linear velocity critical parameter of tool wear quality change—upper limit value of tool linear velocity. Through appropriate control during processing, the cutting speed of the tool does not exceed the upper limit. Value, tool wear speed is low, which is one of the ways to reduce tool wear more effectively.
