Surface grinding machine BSG 2550 PLC

Bernardo BSG 2550 PLC

Reduced slip-stick effect thanks to plastic-coated x and y-axis guides.
The longitudinal table guide is flat, while the transverse guide is triangular.
Radial and axial forces are evenly distributed on special backlash-free bearings in the grinding spindle head.
A separate hydraulic unit with heat exchanger prevents vibration and overheating.
High stability thanks to ribbing and dimensioned wall thicknesses.
Digital control of automatic vertical feed with servomotor.
The hydraulic system ensures smooth table movement, even under heavy load.
Rapid approach to workpiece height, automatic lifting after completion of the work cycle.
Adjustable longitudinal and vertical table feed via end stops.
PLC models are equipped with SIEMENS PLC controllers and touchscreens.
