QF 270 Machine for machining the tooth sides of PCD-tipped circular saw blades by the electrical disk erosion process
This disk erosion machine can be used to machine
- circular saw blades,
- cutting tools and
- special-purpose tools.
- The machine features the VOLLMER PMC system with multiprocessor control
- CNC-controlled axes
- 1x for hook angle adjustment (A-axis)
- 1x for erosion disk infeed (X1-axis)
- 1x for erosion disk infeed (X2-axis)
- 1x for erosion path (Z-axis)
- 2x for the tooth feed (V- and W-axis)
- 1x for tangential angle adjustment (Y-axis)
- 1x for saw loading carriage (R-axis)
