The cutting tool industry has been trying for years to replace solid carbide end mills with indexable end mills. There have been many attempts, few, if any have been successful. One factor is the number of cutting teeth per unit of diameter is higher on solid carbide than with indexable end mills. Smaller diameter tools require higher RPMs. Higher RPMs increase the centrifugal force on the insert.
The attractively priced SCHUNK pull-down jaw SNB promises high accuracy on the workpiece, minimal cleaning effort and a longer service life. Unlike previous chuck jaw systems on the market with active pull-down function, the SCHUNK SNB is built in one piece. This ensures a particularly precise workpiece support, a repeatable zero point independent of the clamping force present, increased stability when machining as well as minimal wear.
With a wide range of lightweight initiatives with chuck jaws, SCHUNK is breathing new life into turning applications. The competence leader for gripping systems and clamping technology is now offering a range of diverse claw and stepped jaw models for raw part clamping from the world’s largest range of standard chuck jaws also optionally as a lightweight version.
In addition to a range of around 50,000 standard tools, Sandvik Coromant serves the manufacturing industry with engineered and Tailor Made tools, using a CAPP (computer-aided process planning) system for quotations and order processing. CAPP can be characterized as a part of a design automation system for managing an entire supply chain from quotation all the way to the delivery of the finished product. Johan Hammarlund, manager for rule-based design and design automation at Sandvik Coromant, tells us more.
Uncontrolled vibration creates multiple problems in metalcutting operations. Varying forces in the cutting process cause vibration and tool chatter that degrade part surface quality, quickly wear or break cutting tools and damage machine tool components. Trends in product design can also incite vibration.
