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

Affected by processing materials. The raw material of the product is an important factor that directly affects the hardness of the part. When the user selects the processing material, the hardness of the part is basically determined. If the hardness of the processed material is relatively small, the plasticity will be relatively large. Before parts are processed, engineering and technical personnel of both parties are generally required to conduct docking and communication.

Influence from the shape of the tool. To realize the conversion of blanks into parts, machining tools are indispensable. The rake angle, cutting edge fillet and the wear of the tool blade face will have a great impact on the hardened layer of the part surface; the hardness and hardness of the part surface The depth will also increase as the rake angle of the tool decreases, and the wear on the cutting edge and the back surface increases. The influence of the cutting amount, the change of the feed amount and the cutting speed will also affect the hardness of the part in the process of machining. When the economic speed of the tool increases, the surface hardness also increases. If the cutting speed of the tool increases, the contact time between the tool and the workpiece surrounding the part will be shortened, the probability of plastic deformation will also decrease, and the hard layer and hardness will also decrease.
