Grindmaster Series

Image of Internal Grinder - Grindmaster Series

Features :

3-Axes Complex CNC Internal Grinder uses Computer-aided Numerical Controller to control the workhead (X axis), ID/OD wheelhead (W axis) and ID wheelhead (Z axis). With one time chucking action, the Grindmaster 45 can perform complex and precision grinding operations, ie : internal diameter, outside diameter, shoulder grinding, taper grinder and end-surface grinding, etc.

Grinding Operation Example :

The closed-loop system design of X-axis ensure high precision requirement for grinding operation. Further more, auto sizing devices can be chosen to reinforce accuracy performance of Grindmaster 45. Evolutional design of the W-axis swiveling function makes Grindmaster 45 meet the flexibility requirements of job shop manufacturing.

Optional Accessories :

  1. Spare Wheel
  2. Spare Wheel Flange
  3. Spare Internal Grinding Spindle
  4. Transformer
  5. CE Mark
