Machining refers to the process of changing the overall dimension or performance of the workpiece through a kind of mechanical equipment. According to different machining methods, it can be divided into cutting and pressure machining. What are the factors that affect the machining hardness?

Affected by processing materials. Raw materials of products are important factors that directly affect the hardness of parts. When selecting processing materials, the user basically determines the hardness of the parts. If the hardness of the processed material is relatively small, the plasticity will be relatively large. Before parts processing, engineering and technical personnel of both parties are generally required to conduct docking and communication.

Influence from tool shape. In order to convert blank into part, machining tools are indispensable. The wear of tool rake angle, cutting edge fillet and tool face will have a great impact on the hardened layer of part surface; The hardness and depth of the part surface will also increase with the decrease of the tool rake angle and the wear of the cutting edge and the back.

The influence of cutting amount, feed rate and cutting speed will also affect the hardness of parts in the process of machining. When the economic speed of the tool increases, the surface hardness will also increase. If the cutting speed of the tool increases, the contact time between the tool and the workpiece around the part will be shortened, the probability of plastic deformation will also be reduced, and the hard layer and hardness will also be reduced.
