BG/ZA/VSS: Grinding of machine knives with additional stroke
This specially adapted machine geometry allows the grinding of machine knives.
BG/ZA/VSS: Grinding of machine knives with additional stroke
This specially adapted machine geometry allows the grinding of machine knives. Thanks to the combination of a stone axis (Z-axis) to compensate for stone wear and an additional feed axis (W-axis) for grinding the workpiece, great flexibility is achieved in conjunction with high rigidity. A combination with an additional vertical axis (V-axis) and a rotation axis (C-axis) is possible.
In addition to the technical data listed in BG, the machine has the following technical specifications:
- Sanding length 300-640 mm (option: 1,000 mm)
- Mounting flange for grinding wheels Ø 200-710 mm (or segments)
- Spindle drive 22-37 kW
- Spindle with backlash-free preloaded precision bearing, designed for peripheral speeds of up to 50 m/s
- CNC grinding machine with four CNC axes:
X-axis = main feed axis, grinding tables driven by linear motor
A-axis = tilting axis/cutting edge angle
C-axis = horizontal rotation axis (option)
V-axis = vertical axis (option) - W axis = feed axis grinding wheel to compensate for grinding wheel wear
- Z-axis = linear pressure axis against grinding wheel
- Digital axis drives on preloaded ball screw or precision reduction gear A-axis, digital axis drive linear motor for X-axis
