Double Column Vertical CNC Grinding Machine

The MKL (double column) 654 double vertical CNC grinding machine is composed of three axial directions, in which the X axis is the transverse feed system, and the Z1 (grinding) and Z2 (grinding) axis are grinding wheels

Product Details

Main application of machine tool

1.The Double column vertical CNC grinding machine is composed of three axial directions, in which the X axis is the transverse feed system, and the Z1 (grinding) and Z2 (grinding) axis are grinding wheels。

2.The main functions of this machine tool: the machine tool can grind the inner hole, inner cone hole, step hole, inner end face, outer cylinder and outer end face of the work piece. The grinding cycle is completed automatically (including automatic feed, automatic dressing grinding wheel, automatic compensation, automatic rough grinding, fine grinding, automatic tool withdrawal).
