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.
