EH Geometry
The stable cutting edge enables feed rates in the range of f = 0.25-0.4 mm/rev, during grooving and parting-off, which results in reduced machining time across multiple operations. Reliable chip evacuation and control is ensured by a special chip formation. High feed rates require a stable machine when grooving and parting-off, as well as secure clamping of the workpiece. Starting from a feed rate of 0.3 mm/rev (0.012"/rev), HORN recommends reducing the infeed for the first 3—4 mm (0.118"- 0.157") during grooving and parting-off.
