What are the factors that affect the tool life
Cutting fluid quality.In addition to cutting fluid in the process of metal processing to improve lubrication, as well as the role of cleaning and rust prevention. The cleaning and chip removal of cutting fluid is often indispensable in metal cutting.
Cutting parameters.The cutting speed, feed rate and cutting depth have great influence on the tool life, and the cutting speed is the most important.
The material of the workpiece being machined.Better thermal conductivity of the workpiece material, by cutting away from the workpiece and by more heat, more conducive to reduce the cutting zone temperature, reduce wear of the tool workpiece; the hardness and strength of the material is high, the cutting force is greater, the greater the power consumption, the cutting temperature is higher, so that the tool wear.
Tool surface coating.Through chemical or physical methods to form a film on the surface of the tool, so that the cutting tool to obtain excellent comprehensive cutting performance, so as to meet the requirements of high-speed machining. The surface hardness and the life of the tool can be greatly improved by using the coating technology without reducing the tool strength.
Tool material.The cutting tool material is the fundamental factor that determines the cutting performance of the tool, and it has a great influence on the machining efficiency, machining quality, machining cost and tool durability. The harder the cutting tool material, the better the wear resistance, the higher the hardness, the lower the impact toughness, the more brittle the material.
