How to do a good job in wire cutting of silicon steel sheet stators and rotors?
Wire cutting of silicon steel sheets is the optimal solution for customized core samples. Compared with laser cutting and other cutting processes, wire cutting has the following advantages:
1. It can achieve a tolerance dimension of within +/-0.02mm for the entire product, and can avoid the problem of uneven appearance caused by the dimensional difference fluctuations of single sheets in laser cutting.
2. Since there is always coolant for cooling during the wire cutting process, it can minimize the increase in iron loss caused by thermal stress and punching shear stress. Through relevant research and tests, among the four processing technologies of stamping, laser cutting, water jet cutting, and wire cutting, wire cutting has the smallest iron loss value.
3. The surface roughness of wire – cut products is significantly better than that of products cut by laser or stamped.
4. Since wire cutting is an electro – erosion process, there is theoretically almost no possibility of burrs, which is beneficial for improving the lamination factor of the product; and the lamination factor is closely related to the final performance of the motor.
Best utilizes many years of experience in wire cutting of silicon steel sheets and has accumulated years of manufacturing and processing experience. It can provide customers with the optimal solutions in terms of product cost, performance, workability, and delivery time.
