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:

  • The machine tool adopts the fixed wheel frame and the movable layout of the guide wheel frame.

  • The grinding wheel has a cantilever structure, and the spindle of the grinding wheel adopts multi-piece long-axis bearing dynamic pressure oil film bearings.

  • The regulating wheel is a cantilever structure, and the guide wheel spindle adopts an integral 1:30 cone sliding bearing.


Feeding device:

  • The feed rail of the regulating wheel frame adopts a dovetail needle roller guide, and the feed uses a differential screw.


Dressing device:

  • The reciprocating of the sand and guide wheel dresser adopts hydraulic transmission and stepless speed regulation.


Electric control device:

  • Regulating wheel adopts AC frequency conversion stepless speed regulation.
