Characteristics

The UBH 100 CNC universal grinding machine is the heaviest machine produced by TOS Hostivař. Thanks to the concept with a grinding headstock moving in the X and Z axis, allows the workpiece to be clamped between points 8,000 mm long and weighing up to 9,000 kg.

It has a turning diameter of the workpiece clamped between the working headstock and the tailstock up to 1,000 mm. The modular concept of the machine allows any length configuration of the machine together with a large variability of optional accessories. Development of a UBH 100 CNC center CNC grinder in cooperation with CTU and RCMT.

Temperature sensors for monitoring the thermal stability of the machine.
The concept of separate front and rear bed.
Advanced grinding spindle diagnostics using temperature and vibration sensor.
Sealing of the grinding spindle with a labyrinth seal and sealing air.
Rolling bearing of the grinding spindle in precision spindle bearings with permanent grease filling.
Modular concept of grinding headstock.
