Sandvik Coromant_CoroCut QD parting-off systemSandvik Coromant claims a new blade for its CoroCut QD parting-off system, when used combination with new process methodology, improves the tool’s stability by realigning the resultant cutting force.

The company says its engineers have developed a solution that takes advantage of capability in modern turning centres and multi-task machines to feed the tool in the Y direction. In the new concept, the top face of the insert is placed parallel to the end of the blade, as if rotating the insert seat 90° anti-clockwise. The new blade cuts its way into the workpiece with its front end, which roughly aligns the resultant vector of cutting forces with the longitudinal axis of the blade.

The new CoroCut QD blades come in widths of 3 and 4mm. Standard length versions (in both 3 and 4mm widths) are offered for parting up to 120mm diameter, as well as an extra-long 4mm wide blade for parting up to 180mm diameter.
