GrindMaster SERIES
Description
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, ie : internal diameter, outside diameter, shoulder grinding, taper grinder and end-surface grinding …etc.
Grinding Operation Example:
- 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 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.
