Cutting Units

Cutting and Chamfering Machines

Machines suitable for cutting and chamfering plastic pipes by means of rotating cutters. The machine’s main characteristic is its dust-free cutting operation. Due to a special central clamping device, idle time is kept to a minimum.

 

Cutting Saws

Pneumatically activated radial saws suitable for cutting pipes and profiles made of thermoplastic materials. Easy operation of the saw on start-up of the extrusion line thanks to the possibility of raising the upper double pipe clamps. Clamping jaws according to the pipe diameter or profile shape guarantee an angular cut.

 

Precision Cutting Saws

When high extrusion speed, short cutting lengths and small tolerances are requested, GRAEWE precision cutting saws are the perfect solution. The saw carriage (driven by an A.C. servo drive) moves along with the extruded material, keeping trace and speed synchronously. Very narrow tolerances are therefore guaranteed.

 

Cutter

Pneumatically or hydraulically activated cutting knife for burrfree cutting of pipes or profiles.

 

Servocutter

For chip and burrfree cutting by means of rotating knife.
