Tos UB 32,40, 50 cylindrical grinding machine

the features and specifications of the TOS Hostivar universal cylindrical grinders, including the UB 32, 40, and 50 ranges. These machines can handle workpieces with diameters of 320 to 500 mm and a maximum length of 3,000 mm, and can perform internal grinding. The machines can be controlled manually or work in a fully automatic grinding cycle. They can clamp workpieces between centers, on one side using a chuck or a magnetic plate. The bed of the machine is made of high-quality gray cast iron and is heat-treated to ensure dimensional stability, strength, and vibration damping. The wheel-head box is also made of high-quality gray cast iron, and the grinding spindle is mounted in radial hydrodynamic flexible slide bearings and axial slide bearings, and is surrounded by an oil film in three places. The lubrication of the grinding spindle bearings is circulating, using a separate tank. The lubrication system is fitted with electric indication of lubrication oil flow, which shuts down the grinding wheel drive motor if there is insufficient flow.
