Abstract

1279238 Making cutting tools; coiling wire; brazing MARWIN CUTTING TOOLS Ltd 11 Aug 1969 [17 May 1968] 23468/68 Headings B3A B3E and B3R A helical face piece for a cutting tool and having a length greater than one third of its lead is formed by hot deformation. A ceramic, high speed steel or sintered tungsten carbide blank of rectangular, circular or elliptical cross-section is placed in a feed slot 12 of a former 10. After the blank has been heated by an induction coil 14, it is pushed by a probe 34 along a helical slot 13 of the former 10 to form the blank into a helical shape. As the blank is pushed from the zone of the heater 14 it is quickly cooled by a high conductivityliner 16, after whichit is passed under pressure from a following blank through an insulator 24 and a sleeve 26 packed in asbestos 28 and ceramic 29. The formed helix is removed through a door 32 of a cooling box 30, after which it is shot blasted, brazed on to a cutting tool body and ground to final shape. The helix angle is above 10 degrees and a member with a high angle may be formed in two stages.
