- Internal and external cylindrical grinding
- Hydrostatic bearing spindle for high surface quality
- Massive machine frame for heavy workpieces
- Swivel headstock for conical grinding of short workpieces
- Integrated Z-axis rapid traverse with manual return
- Comprehensive standard accessories
Detail
- Large, heavy-duty machine bed offers space for workpieces up to 2000 mm in length and 320 mm in diameter
- Wide and precision-ground guides guarantee accuracy along the entire length of the workpiece and allow high workpiece weights
- The table can be swiveled in 2 directions - its movement in the longitudinal direction is carried out manually using a handwheel or automatically using an adjustable hydraulic feed
- The robust feed valve enables very fine feed control of the X-axis and the user can set a dwell time at the end of the longitudinal table movement
- A hydraulic ratchet feed simplifies the exact positioning of the X-axis - limited by an adjustable zero stop
- The hydrostatically mounted grinding spindle enables maximum precision and surface quality with an extraordinary service life and stability
- The powerful grinding spindle motor is designed for continuous operation
- The robust grinding spindle head can be swiveled to the left and right by 30°, the work spindle head by 45°
- Standard internal grinding device
- Integrated Z-axis rapid traverse with manual return
