Silent ToolsTM - 2

Reducing vibration in focus Vibration-prone operations pose a constant threat to productive and secure machining, especially when dealing with long overhangs or deep cavities. Reducing process parameters such as depth of cut, speed or feed is one aspect to consider, but it will most likely have a negative impact on productivity. A more productive solution is to use Silent Tools™. Silent Tools is a unique range of long-reach cutting tools and adaptors for turning, milling and boring, designed with a damping system inside the tool body to minimize vibration. For components requiring slender...

Silent ToolsTM benefits • Improved process security Improved surface finish Productivity gains Reduced cost per component Difference in vibration between undamped and damped tool. Inside the tool is a pre-tuned damping system that consists of a heavy mass, supported by rubber spring elements. If vibration arise, the kinetic energy will be absorbed by the damping system. This leads to minimized vibration and greatly improved productivity. Internal turning of mandrel. Maximum reach with Silent Tools elliptical adaptors. CoroTurn® SL with Silent Tools turning adaptor. Shoulder milling with...

Silent ToolsTM for turning Secure and productive turning Silent Tools turning adaptors Internal turning is very sensitive to vibration. It is essential to select the largest possible tool size and to minimize the overhang in order to obtain the best stability and accuracy. Choosing the right turning adaptor has a big impact on production economy. The Silent Tools turning adaptors are ideal for successful turning operations at overhangs reaching from 4 up to 14 times bar diameter, and are available from diameter 16–250 mm (0.630–9.84 inch) as standard solutions. The easily replaceable...

Silent ToolsTM for milling Maximize your milling cutter productivity Working with rotating tools differ from turning, where you have a boring bar in a rigid tool post. Most considerations for successful operations are however the same, such as workpiece set-up and machine stability. Make the most out of your milling operation with Silent Tools. CoroMill® 390 with integrated damping By integrating Silent Tools technology into the extra-long, extremely versatile CoroMill 390 end mills, you can easily stabilize your machining process while maintaining required surface finish and high-quality...

Silent Tools™ arbor milling adaptors The Silent Tools arbor milling adaptors are available for a large number of cutting concepts and for a wide range of applications, including long reach face milling, deep shoulder and side milling, cavity milling, slot milling and profiling. Undersized adaptors with nominal diameter cutters are first choice for greatest productivity in deep cavities, while nominal diameter adaptors are available for maximum stiffness and capacity for oversized diameter cutters. Productivity gains: At least 50% for the shortest adaptor lengths and up to 300% for longer...

Silent ToolsTM for boring Flexible boring at long overhangs Internal boring of large-diameter holes and deep holes is a particularly vibration-prone operation, especially when machining with long overhangs. To avoid vibration-related issues such as bad surface texture, insufficient accuracy and increased insert and machine tool wear, a stable tooling solution is a necessity. Sandvik Coromant offers Silent Tools for rough and finish boring. The tools are designed with a strong dedicated interface between bridge and damped adaptor, and the same adaptors and bridges can be used for both rough...

Customer case CoroBore® XL with damped Silent Tools adaptor boring a landing gear. Performance: Finishing of a chamber The customer produces 200–250 components per year, but had problems obtaining the desired surface finish without encountering vibration. Prior to the finishing operation, two roughing operations were performed which gave a concentricity error of 0.02. By changing to Silent Tools, the customer benefited from time savings of up to 12.3 minutes per machined part. No vibration, a good finishing surface and no conical dimension of the hole were all welcomed results. The radius...
