Series BG/ZA/NT

BG/ZA/NT: Economic grinding simple geometries

The CNC-controlled flat bevel grinding machine of the series BG/ZA/NT is designed for economic grinding of workpieces with simple geometries. The grinding machine is equipped with three contour giving axes. It is comparable with the flat bevel grinding machine DG/NT with the exception that the BG/ZA/NT has a horizontal grinding table.

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

• grinding length 300–640 mm
• reception flange for grinding wheel: 80–710 mm ∅
• spindle drive 6.5–45 kW
• precision mounted grinding spindle, designed for circumferential speed of up to 50 m/s
• grinding table with three axes:
  • X-axis = main feed axis of the grinding table, powered by a linear motor
  • Z-axis = infeed axis for grinding wheel
  • A-axis = tilt axis/grinding angle
• digital drive for the axes, preloaded ball bearing spindle, Z-axis or precision reduction gear (A-axis), digital powered X-axis with linear motor
