Ravna brusilka BSG 2550 PLC

Bernardo BSG 2550 PLC

Reduced slip-stick phenomenon thanks to X and Y axis guides with plastic coating
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 headstock
Separate hydraulic unit with heat exchanger prevents vibrations and overheating
High stability due to ribbing and dimensionally stable walls
Digital control of automatic vertical feed with servo motor
Hydraulic system ensures smooth table movement even under heavy loads
Rapid approach to the workpiece height, automatic retraction once the work program is completed
Adjustable longitudinal and vertical feed of the table thanks to end stops
PLC models equipped with SIEMENS PLC controllers with touch screen
