Flat bevel grinding machine for the machining of mechanical knives

BG/ZA/VSS/NT2-CNC: Grinding of mechanical blades

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-CNC the machine is classified by the technical specifications as follows:

  • grinding length 300–640 mm (18.8"–25.2")
  • spindle drive 22–37 kW
  • reception flange for grinding wheel Ø: 200–710 mm (7.78"–27.95"), resp. segments
  • precision mounted grinding spindle, designed for circumferential speed of up to 50 m/s (164 ft/s)
  • digital windows control
  • workpiece-related programming software
  • TeamViewer for diagnosis/remote control of CNC and SPS functions
  • 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-Achse = rotation axis horizontal (option)
    • V-Achse = 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
