1. Grinding wheel has been carried out, and one-time feed is adopted in a straight-forward mode, which greatly improves the overall processing efficiency and stability.2. The maximum width of the grinding wheel can reach 300mm, and the grinding of workpieces with 15 steps can be completed by one-time operation.3. Equipped with hydrostatic spindle, it has excellent features such as high precision, high rigidity, high shock resistance, high bearing capacity and long life.4. The headstock and tailstock are driven by dual servo motors, which can avoid the interference problem of traditional driving rings.
