APPARATUS FOR CONTINUOUSLY MACHINING HELICOIDAL GROOVES IN A CYLINDRICAL OBJECT

摘要

Continuous machining of grooves in a cylindrical dielectric rod is achieved by guiding the rod into a heating machining head incorporating a rotating cutter made from a chemically etched stainless steel sheet and guiding the rod downstream of said head. A chip removing head made of a rotating unit comprising channels in which said chips are aspired by decompression effect of a gas is mechanically coupled with and upstream of the machining head.
