The Universal grinding machine UBB 50 CNC is based on the all-purpose cylindrical grinder UB 50 CNC. It is a cylindrical grinder for workpieces of maximum diameter of 500 mm and maximum length of 3,000 mm, with an additional B-axis.
The B-axis enables the use of up to three grinding wheels making it possible to grind a workpiece completely while clamping it only once, with minimum additional time and maximum precision using internal grinding.
