Depressed Grinding Disc Processing Technology
Depressed grinding disc processing must have strict processing specifications and maintenance procedures. Here are some tips for you.
The grinding process of the depressed grinding disc in stockis more complicated than other cutting processes. The cutting process of the abrasive particles includes sliding, plowing and cutting.
The elastic deformation and plastic deformation of the grinding disc during grinding are large. Other cutting methods are less common and directly affect the dimensional accuracy, roughness, grinding heat, surface quality and grinding efficiency of the machined workpiece. In the course of use, it is necessary to understand the critical condition that the elastic zone is transformed into a plastic zone and the plastic zone is converted into a cutting zone.
Compared with ordinary machining, in the processing of ordinary grinding discs, the tangential force is much larger than the normal force, while the grinding is characterized by the normal force about 24 times the tangential force. The stiffness of the grinding system is greatly affected. The grinding force consists of two parts: cutting force and friction. The rough grinding is mainly based on cutting force, and the fine grinding is mainly based on friction.
Grinding is an energy-consuming processing method that is 20 times larger than other processing methods. Attention must be paid to the effects of grinding heat and temperature rise on the process.
In the finishing process, the size, roundness, and precision of the depressed grinding disc in stock are guaranteed.
