  • Specification
  • CONFIGURATION

1.This cylindrical grinder has the characteristics of high precision, strong rigidity and high efficiency, and is suitable for grinding cylindrical and conical workpieces.

2.The workpiece, the external grinding wheel, the oil pump and the cooling pump are driven by independent motors.

3.The longitudinal movement of the worktable of the machine tool can be driven by hydraulic stepless speed change or handwheel transmission.

4.The horizontal feed of the grinding wheel carriage can be hydraulically carried out micro-automatic periodic feed and rapid forward and retreat, and the handwheel can also be used to achieve two kinds of feed.
