Product Details


  • The CNC cylindrical grinder is suitable for batch production of cylindrical parts grinding with high performance to price ratio.

  • The machine tool standard adopts German SIEMENS CNC system, and the executive system is driven by the CNC servo driver and servo motor.

  • Worktable longitudinal travel (Z) and wheelhead cross travel (X) which with the high infeed accuracy are realized by the servo motors driven the ball screw transmission.

  • With the SIEMENS CNC system programming and human-machine interface, simple and easy, and equipped with other CNC systems and configured online automatic measuring instruments for customers' choice.

  • Simple and easy to operate for the grinder, after simple training, it can be operated easily. By setting the parameter of longitudinal grinding or plunge grinding by CNC control panel, an auto-grinding for the different workpiece is realized. 

  • This machine has automatic shifting of the table, which can automatically grind multiple steps of a workpiece. The multi-step can be arbitrarily arranged for longitudinal grinding and cutting into grinding sequence and grinding process parameters.

  • CNC control system with the function of wheel dressing and compensation automatically.

  • Wheelhead spindle is supported by three bushing hydro-dynamic bearing, and high precision hydro dynamic-static bearing is also available for the user.

  • Timing provision of lubrication for machine moving parts according to program designing. Automatic lubrication of all moving parts. Tailstock has two ways:hydraulic and manual.

  • Workhead spindle driven by variable frequency motor and frequency inverter, and programmed through M-code and S-code of CNC system for stepless speed.

  • Wheelhead swivel 180° for changing outside grinding and inside grinding. Optional full-closed guard.
