Product Details
Machine tool main characteristics:
Through feed grinding--Through-grinding processing of various cylindrical parts, ring parts and long bars.
Plunge feed grinding manually --For the cutting and grinding of cones and various shaped rotating parts. (CG-40B)
Plunge feed grinding sime-automatically or automatically --For the cutting and grinding of cones with a cone less than 1:20 and various shaped rotating parts. (CG-50A)
Grinding bed:
The normalized heat treatment and natural aging treatment of high-quality castings are used to stabilize the internal structure, ensure strong wear resistance and small deformation during use.
Grinding and regulating device:
