Product Details


Machine Tool Main Characteristics:

  • Through feed grinding--Through-grinding processing of various cylindrical parts, ring parts and long bars.

  • Plunge feed grinding--For the cutting and grinding of cones with a cone less than 1:20 and various shaped rotating parts.


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 spindle bearing of the grinding wheel is a four-piece tiltable ball head supporting bearing bush with high precision.

  • The spindle structure of the grinding wheel adopts double support, and the bearing pad adopts four tiltable ball heads to support the bearing pad, which has large bearing capacity and high precision.

  • The regulating wheel adopts AC frequency conversion stepless speed regulation,not only can stepless speed regulation, but also has anti-backward drag function.


Feeding device:

  • The feeding structure adopts a servo motor to drive a high-precision planetary gear reducer, and drives the roller screw through a coupling to achieve feeding.


Dressing device:

  • The grinding wheel dresser is driven by a servo motor roller screw, which can dress any step without the need for copying template. The guide wheel dresser adopts a motor-driven roller screw reciprocating, stepless speed regulation, the low-speed movement of the dresser is good, and the automatic dressing process can be completed.


Electric control device:

  • The operation adopts touch display frequency man-machine dialogue, with automatic cutting grinding program, and the feed amount, speed, time and step difference are adjustable.

  • The electrical system adopts the Japanese Mitsubishi system (optional Siemens).
