The course of the grinding process is very important in the machining process. The general requirements for abrasive tools are relatively high, so we should pay more attention to the factors that affect the grinding quality in the process of surface treatment.
Here are the main factors:
1, Grain size and hardness of the grinding wheel, properties of abrasives, the material of work piece
2, The linear speed of the grinding wheel, the linear speed of the workpiece, the feed speed of grinding wheels
3, The properties and supply of coolant for machine tools
4, The shape precision of grinding wheels. Generally, the diamond pen, diamond wheels or ordinary abrasive tools are used to dress the grinding wheel. During the dressing process, the shape of thread formed on the surface of the grinding wheel will be copied to the workpiece, so the shape precision of grinding wheel affects the surface of work piece directly.
5, In the process of grinding, the surface quality of the work piece is also affected by many other factors, such as the surface finish, roundness, cylindricity, grinding burn, grinding crack, residual stress and so on.
