Designed to improve stability, the CoroCut QD
part-off blade feeds in the Y direction to realign cutting forces and reduce noise levels.
Mamondiong said the beneficiaries are
part-off if the initial list from the Human Rights Victims Claimants Board (HRVCB).
Adding to the existing line of Groove 'N Turn[R] inserts, these
part-off tools are offered with or without 7-degree cut-off lead angles and with right- or left-hand cut-off angles.
New tooling was also implemented for the
part-off operation.
The productivity team suggested a simpler part-off operation, replacing two existing tools with one Sandvik Coromant Grade 4125 insert optimized for brass.
Combined savings in cutting and tool changing time increased productivity for the part-off operation 63%.
Part-off operations on the company's Mori-Seki horizontal lathe routinely cut tube-shaped forgings into shorter lengths for subsequent machining.
To part-off the difficult alloy with conventional grooving tools, Multax machinists turned the rings at just 95 sfpm surface speed and 0.003 ipr feed.
