Bernardo BSG 2550 PLC surface grinding machine
Features Bernardo BSG 2550 PLC surface grinding machine
The solidly built surface grinding machines in the BSG series are equipped with an automatic vertical infeed as standard. All main assemblies such as the column, base and slide are made of high-quality cast iron. Thanks to the extensive range of standard accessories, these models offer an optimum performance package for tool and mould making.
- Low slip-stick effect due to plastic-coated counterguides in x- and y-axis
- Longitudinal table guide V-flat, transverse table guide double-V
- Axially and radially backlash-free preloaded special bearings in the grinding spindle
- Separate hydraulic unit with heat exchanger, avoids vibrations and thermal load
- High stability due to strong ribbing and generously dimensioned walls
- Digitally controlled automatic vertical feed with servo motor
- Sophisticated hydraulic system ensures smooth table reversal even with high table loads
- Rapid feed to the workpiece height, adjustable finishing and burnout strokes, automatic lift-off at the end of the programme
- Adjustable longitudinal and transverse table movement by means of end stops
