Latest milling adaptors include higher metal removal rates

With the upgraded Silent Tools milling adaptors from Sandvik Coromant, production engineers now have an effective way of enhancing productivity, process security and surface finish in vibration-prone, long-overhang operations.

Benefits such as the significant reduction of chatter and vibration make them today’s first choice for any machine shop looking to optimise the performance of its long milling cutter assemblies. 

“Inside the adaptors is a pre-tuned passive damper - a counteracting mass that acts as a shock absorber,” explained Pål A. Sollie, Product and Application Specialist at Sandvik Coromant.

Sollie continued: “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 which, 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.

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