Silent Tools milling adaptors from Sandvik Coromant respond to higher metal removal rate demands

Damped cutting tools Silent Tools milling adaptors from Sandvik Coromant respond to higher metal removal rate demands
The latest Silent Tools milling adaptors from Sandvik Coromant are designed to offer improved damping characteristics and respond to the need for greater metal removal rates and reduced vibration wherever long, slender milling tools are deployed.

Suitable for all ISO material groups, the new Silent Tools milling adaptors can be deployed on tool assemblies with useable lengths from 4xD and are available with Coromant Capto and HSK-A/C as machine-side interfaces.

Explains Pål A. Sollie, product and application specialist at Sandvik Coromant: “Inside the adaptors is a pre-tuned passive damper - a counteracting mass that acts as a shock absorber. The damper improves the dynamic behaviour of the tool assembly to a level where there is room to achieve the best milling tool quality and unbeaten metal removal rates for a variety of milling applications with slender tools, whether it is face milling (even at high feed), deep shoulder and side milling, pocketing, slot milling, profiling, circular ramping or helical interpolation.”

Additional advantages include undersized shanks that, where required, allow side clearance between the adaptor and workpiece. This permits the use of a nominal diameter cutter – rather than an oversized cutter – which is advantageous because a lower mass cutter is more productive than a larger version on a long, slender assembly. Having this flexibility avoids the need to compromise component designs and productivity when the use of slender milling tool assemblies is required.
