MAIN FEATURES:
1.Table can be tilted for conical grinding operations and scale allows adjustment to desired position
2.Spindle stock can be swivelled 180 degree for inside grinding operations
3.Main spindle is mounted hydro-dynamically – oil film prevents contact between spindle and bearing
4.Longitudinal table guide and grinding spindle stock cross guide feature V- and flat guiding each
5.Strong reinforcements and generously designed walls make the machine base resistant to temperature fluctuations and deformations
6.Oil film between spindle and bearing reduces the vibrations to a minimum to achieve top results and high accuracy
7.Stepless feed adjustment with selective programmable stop at end of each table movement
8.Precisely adjusted spindle head and solid grinding spindle stock to achieve top processing results at various grinding operations
9.Precisely polished and manually finished guideways in x- and y-axis
10.Hydraulic or manual resetting of grinding spindle stock
11.Longitudinal movement of table is either manually by handwheel or automatically by hydraulic feed
12.Grinding spindle features bearings on both sides and adjustable sliding flat grids
