CNC TURNING

The main purpose of soft machining in JB is the manufacture of bearing rings, hous-ings, hub shafts, cardan shafts, as well as the processing of cast housings for bearingunits.
Incoming material for turning: bars, tubes, forgings, castings, rings
Machines used for turning are six-spindle lathes for large series and CNC machinesfor processing rings of larger dimensions and small series.
Technological possibilities of soft machining of rings for bearings in JB:

  • multispindle machines: diameters up to 100 mm
  • CNC machines: diameters up to 500 mm.

 

The basic document which defines methods and norms for measuring predefined pa-rameters of processing is the Process Control Plan. It contains:

  • dimensional control (inner diameter/outer diameter/ width of rings, angles, race-ways, depressions, radius)
  • shape deviations (ovality, profile deviation, parallelism, conicity,raceway deviations, clearance)
  • visual inspection
  • methods and instruments for measuring
  • frequency of measurements
