Series BG/ZA/VSS/NT

BG/ZA/VSS/NT: Grinding of machine blades with additional stroke

The machine geometry is specially designed for grinding machine knives. Due to the combination of wheel axis (Z-axis) for the compensation of the grinding wheel wear and the additional infeed axis (W-axis) for grinding the workpiece an even bigger flexibility combined with high rigidity is realized. Here a combination with an additional vertical axis (V-axis) and a rotation axis (C-axis) is possible.

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 Ø: 200–710 mm, resp. segments
• spindle drive 22–37 kW
• precision mounted grinding spindle, designed for circumferential speed of up to 50 m/s
• grinding table with four:
  • X-axis = main feed axis of the grinding table, powered by a linear motor
  • A-axis = tilt axis/grinding angle
  • C-axis = rotation axis horizontal (option)
  • V-axis = vertical axis (option)
• W-axis = infeed axis grinding wheel for compensation of grinding wheel wear
• Z-axis = linear pressing axis against grinding wheel
• digital drive for the axes, pre-stressed ball bearing spindle or precision reduction gear (A-axis), digital powered X-axis with linear motor
