SCREW SLOTTING MACHINES
Double Cutter Slotting Machine with Protective Cover
Slotting machine with double cutter in a protective cover is used for screws and small fasteners, the production of which excludes the technology of forming splines by cold heading.
Metal cutting machine for slotting. Straight-sided splines and involute profile splines on shafts are formed by a milling cutter by rolling. The cutter rotates and simultaneously performs a feed motion (moving along the axis of the workpiece), the workpiece also rotates with a frequency depending on the number of splines formed.
The boring process is highly accurate, stable and occurs at high speeds. The equipment does not make much noise.
After two step boring, chips are removed automatically, which eliminates the formation of burrs on the head of fasteners. Fastener splines of small diameters are usually milled in one pass, large diameters in two passes.
