Series BG/NT2-CNC

Flat bevel grinding machine for complex geometries

BG/NT2-CNC: Surface grinding of complex geometries

The machine BG/NT2-CNC is the most often employed flat bevel grinding machine of the Berger Gruppe. It machines a surface grinding at workpieces with complex geometries.

The grinding machine is equipped with four contour giving axes and one tool axis.

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

  • spindle drive 6.5–45 kW
  • grinding length 300–640 mm
  • precision mounted grinding spindle, designed for circumferential speed of up to 50 m/s
  • reception flange for grinding wheel: 80–710 mm ∅
  • grinding table with four axes:

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

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