Product Description

M7480EVertical Spindle Surface With Rotary Table
The machine tool is a vertical grinder with multiple functions and wide applications, which mainly serves for manufacturing or using cold stamping dies.
The machine tool can undertake an integral grinding for the stamping dies with handles and guide bars. In addition to the grinding of plane surface, concave, convex and shoulder plane, the grinding for internal and external surface, the shape grinding for diffenent size stamping die edges with different requirement to the curvature radius cambered surface can also be done.
The grinding head spindle is equipped with high precision rolling bearings with automatic up and down operation, line guide rails and level travel. The column can be adjusted by three points.
