In addition to the technical data indicated at BG-CNC the machine is classified by the technical specifications as follows:

  • precision mounted grinding spindle, directly powered by a special motor, capacity 6.5 kW
  • grinding length 150 mm
  • frequency converter for continuous adjustment of the spindle speed from 2000 to 6000 Upm, capacity 7.5 kW
  • reception flange for grinding wheel: 80–200 mm ∅
  • grinding table with four axes:

    • X-axis = main feed axis of the grinding table, powered by a linear motor
    • Z-axis = linear pressing axis against grinding wheel
    • A-axis = tilt axis/grinding angle
    • B-axis = axis of rotation

  • W-axis = infeed axis for grinding wheel, continuously adjustable and freely programmable
  • digital drive for the axes, prestressed ball bearing spindle, Z-axis or precision reduction gear (A- and B-axis), linear motor for X-axis
