Advantages for you:

More rigid construction (monobloc design) improves tooth accuracy
Measurement of complete tooth geometries ensures higher cutting edge precision
Greater flexiblilty thanks to two-axis co-ordinate feed
Prepared for automatic hollow face and chip breaker machining as standard
Improved performance thanks to higher machining speed
All functions CNC controlled
All-in-one machining for service and production applications in unmanned multi-shift operation, using robotic loading system handling saw blades up to 840 mm in diameter
For machining all tooth geometries of saw blades for either wood or metal cutting
The external dimensions of the CHD 270 sharpening machine are comparable with the existing CHD 251
