Tos UB 63,85,90 universal cylindrical grinding machine

This text describes the features and specifications of TOS Hostivař's universal cylindrical grinding machines, specifically the UB 63, 85, and 90 ranges. The company is dedicated to providing high-quality cylindrical grinders for various workpieces with a maximum length of 6,000 mm and diameter ranging from 630 to 900 mm. The machines can perform automatic grinding cycles for various types of grinding, including longitudinal, plunge, convex or concave diameters of a cone surface, and can also accommodate internal grinding. The machines can be controlled manually or automatically and can be modified for using controlled gauges to control multiple machines.

The machine's bed is made of high-quality grey cast iron and designed to ensure the necessary dimensional stability, strength, and vibration damping. The table and wheel-head are moved on manually ground slides, which are lubricated by an automatic lubrication system combining hydrostatic and hydrodynamic lubrication. The wheel-head grinding spindle is rigid and accurate and can be mounted on a sliding or rolling mount. The machine's lubrication system is fitted with electric indication of lubrication oil flow to shut down the grinding wheel drive motor if there is insufficient flow. The headstock is fitted with a cooling system to ensure thermal stability, and the drive of the grinding spindle is ensured by a three-phase asynchronous motor.

In addition to the machines, the company provides all necessary accessories and offers installation, servicing, repair work, reconstruction, and additional equipment for cylindrical grinders. TOS Hostivař grinders are known for their reliability and precision and are constantly innovating to bring more value to their customers.
