Cut Technologies

CHD 251 & 351 - The complete machining of carbide-tipped circular saw blade tooth geometries in a single setting - to the very highest standard.

Flexibility, speed, precision - CNC controlled, the new CHD series of grinding machines.

CHD 351

The CHD 351 machine version is designed to accomodate saw blade diameters up to 1300mm

The generously dimensioned sliding doors can be opened wide, allowing easy access to the machine interior. Because the work area open overhead, saw blades can easily be loaded by means of a crane or other hoisting equipment.

All other technical features of the machine correspond to those of the CHD 251 machine.

The CHD series grinding machines are equipped with an in-process diagnostic system which performs a continuous check on all machine functions. Any faults occuring are indicated in plain text on the LCD colour screen and can be remedied directly by operating personal.
