Characteristics
The 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.
- Flexible grinding of medium-heavy to heavy cylinders and shafts
- Heavy machine design with variable grinding wheel location.
- Design with one or two grinding headstocks.
- Control system CNC – Siemens 840 Sinumerik D sL
- Grinding spindles with hydro-dynamic suspension or on roller bearings.
- Partial or full cover of machine with grinding mist exhaustion
- SBS Dynamic balancing system of grinding wheel
- Measuring, cooling and electric systems by world leading manufacturers.
- Flexible adjustment of additional components.
