BERNARDO BSG 4080 TDC surface grinding machine

BERNARDO BSG 4080 TDC surface grinding machine was built in Austria in 2018. Designed for fully professional production applications, the machine machines workpieces placed on a magnetic plate or directly on the work table with the utmost precision and accuracy. The hydraulically driven work table with a large magnetic platen moves on hardened and ground guideways, which have been additionally coated with a special Turcite-B coating to increase abrasion resistance. The hydraulic drive, in the form of a separate hydraulic unit with heat exchanger, prevents vibration and overheating, and also ensures safe table feed even under heavy loads. Radial and axial forces are evenly distributed on special bearings without play in the grinding wheel spindle. The BERNARDO magnetic grinding machine weighs 3400 kg.
