For volume bar-fed parts manufacturing, producers are continually seeking solutions that offer more efficient material usage to control their overall costs and support increased bar feed capacity. Ensuring process security through a predictable and consistent tool life is also important to ensure reproducible parts quality, particularly for parting off.
Sandvik Coromant's CoroCut QD is a range of tooling solutions covering parting and SL blades, adaptors, shank and Swiss tools and a new generation of inserts for parting off. It has been developed from the Q-Cut and CoroCut ranges.
The tool attachment is achieved via a user-friendly clamping mechanism. The tool tip seat is tilted 20 degrees and incorporates a back stop to withstand high cutting forces. For insert widths 0.078 in (2 mm) and wider, the insert interface has a rail to increase stability.
When parting off a component, minimized 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 options for a broad range of material types. The PVD insert coating offers better adhesion, improved edge-line qualities and better ER tolerance.
