3-Axes Complex CNC Internal Grinder

 

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 45can perform complex and precision grinding operations, i.e.: internal diameter, outside diameter, shoulder grinding, taper grinder and end-surface grinding …etc.

Grinding Operation Examples:

 
  • Internal diameter straight grinding operation / Outside diameter straight grinding operation.
  • Internal diameter taper grinding operation / Outside diameter straight grinding operation.
  • Internal diameter straight grinding operation / Outside diameter aper grinding operation.

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