Fiber series of grinding wheels processing skills

Fiber series of grinding wheels processing skills:

1. The grinding process is more complicated than other cutting processes. The cutting process of abrasive grains includes sliding, ploughing and cutting. The grinding process of the fiber series of grinding wheels consists of three stages: spark cutting, stable grinding and spark cleaning.

2. The elastic deformation and plastic deformation during grinding are large, and other cutting methods are less likely to directly affect the dimensional accuracy, roughness, grinding heat, appearance quality and grinding efficiency of the machined workpiece. In use, it is necessary to understand the critical condition that the elastic zone is transformed into a plastic zone and the plastic zone is transformed into a cutting zone.

3. Compared with general machining, the tangential force is much larger than the normal force in general machining, while the normalizing force is that the normal force is about 24 times of the tangential force, and the grinding system stiffness is great influence. The grinding force consists of two parts: cutting force and friction. In the case of rough grinding, the cutting force is dominant, and in the case of fine grinding, the friction is dominant.

4. When grinding, ensure the size, roundness and precision of the fiber series of grinding wheels.

5. To improve the roundness of the part, first the blank cannot have excessive roundness and concentricity error.
