Straightening-and-Cutting Machines

WSC

The straightening process can be followed by various second operation: deburring, chamfering, flattening, drilling…

The rotary straightener is set by means of an electrical command, which directly controls the positioning of straightening fingers. Thus, the setup is very quick and does not require any particular training.

Straightening setting parameters are saved in the program and will be instantaneously applied to any subsequent production processes.

The specific cutting system, patented by Buch, is extremely fast, and may be executed burr-free.

While the standard cutting angle is 90o, other values can also be achieved upon request, possibly with different cutting angles at the front and at the back.
