Sandvik Coromant introduces CoroCut QD parting-off concept for deep grooves and long overhangs

In designing CoroCut QD, Sandvik Coromant has paid attention to the development of novel and upgraded parting geometries. When parting off a component, minimised cutting forces and efficient material removal are important. An insert should be as narrow as possible and have a geometry that makes the chip narrower than the groove to provide a parting off operation with good chip control and surface finish. Within the CoroCut QD concept are inserts with five parting geometries and one turning geometry as well as options for 'do-it-yourself' grinding and tailor-made options for a broad range of material types. The PVD insert coating offers superior adhesion, improved edge-line qualities and better ER tolerance. Other key aspects are the tool material and a tooling design for greater process stability. The tool attachment is achieved via a smart yet user-friendly clamping mechanism. The tool tip seat is tilted 20º and incorporates a backstop to withstand high cutting forces. For 2 mm insert widths and wider, the insert interface has a rail to increase stability.
