The grinding aim is to transform all the particles making up a formula to a similar particle size, consuming as low energy as possible.The similar particle size favors thereafter obtaining homogeneous and stable mixtures.The grinding fineness promotes pellet cohesion and the electrical efficiency of the pellet mill.
3d grinding temperature field can be simulated by the finite difference method.When the finite difference method is used to calculate the temperature field, the boundary conditions need to be considered.Unfortunately, the difference equations for internal nodes and boundary nodes are not the same.For cuboid computing domains, there are twenty-six types of boundary nodes.
During grinding, the resin bond may be pushed back, which renders more uniform depth of cut among the cutting edges.Meanwhile, more cutting edges are expected to interact with the silicon surface in the successive grinding processes.Therefore, the spaces among the cutting edges are much smaller than with the 400 wheel.

Grinding temperature is an important parameter in affecting the quality of grinding.The higher grinding temperature would cause thermal damage to workpiece.But in the actual grinding processing, it is difficult to measure the grinding temperature in real time.This paper presents the finite difference method to calculate the grinding temperature.
When designing grinding and honing processes, the entire process chain is always considered.In contrast to geometrically defined cutting edges, the specific cutting energy in grinding and honing is several times higher due to the high share of friction.Such specific cutting properties usually require cooling lubrication in grinding.
