How to choose tool material


The basic requirement of tool material:
In the process of turning, cutting parts is working under the condition of large cutting resistance, high cutting temperatures and intense friction. Cutting performance of cutting parts directly affects the service life of tool. Cutting efficiency also affects processing quality. Therefore, cutting tool material should meet the following requirements:
1 Cutting tool should have a high hardness, hardness of tool material is 1.3-1.5 times higher than the hardness of the workpiece.
2 Cutting tool should have abrasive resistance .
3 Cutting tool should have heat resistance
