How to improve the service life of cutting tools
Aluminum work is as large as possible low speed cutting knife cutting slow pouring blood or water or oil.Stainless steel welding parts as much as possible to work more water to observe the cutting tool but also have low speed or tool wear particularly fastDry hard material as far as possible spray low speed do not high speed that is equal to the knife
In general, turning plastic metal materials with large, should take a larger rake angle, cutting in mild steel, the angle value is slightly smaller, but still maintain a certain value, cutting steel, angle of small, and in the cutting of hardened steel hardness is particularly high, hard alloy tool general with negative rake angle or zero rake angle. But in the turning of the copper alloy, the rake angle of the tool is big and easy to gnaw the knife phenomenon. In general, when the car, the front and rear angle to take some larger, rough car, in order to the strength of the tool, the front and rear angles to be small.
In order to extend the service life of the cutting tool, improve the processing efficiency, first of all to adjust the cutting tool life is the minimum depth of cut, followed by feed, the last is to adjust the cutting speed. The main reason is that the main factors that affect the service life of cutting tools are cutting temperature, cutting heat.
Low speed big cutting knife walking so as not to water injection for stripHigh speed small knife such fine work late quickly but also left 50 children with light alloy knife sideThis is the usual work of ferroalloy
