Problem solvers
If metal cutting tools exceed certain length/diameter ratios, unde-sirable vibrations may be generated in the tool, depending on the material and the cutting edge fitted. If extensions with damping properties are used, these sorts of problems can often be re-solved. The KOMET GROUP® offers a range of damping ele-ments in conjunction with a modular KOMET ABS® attachment point – a plus point from KOMET®.
Tool vibrations restrict the product quality that can be achieved with machining, or do not allow certain operations to be carried out at all. The new damping elements from KOMET® that are being presented at EMO 2009 are tailored to the requirements of precision boring and will be available in two designs. The KOMET ABS® 25 – 32 model sizes consist of a shank that can be clamped in a ThermoGrip® shrink chuck or hydraulic expansion chuck. In the larger heavy-metal designs (KOMET ABS® 40 to 63), the new damping elements are also equipped with an KOMET ABS® attachment point on the spindle side. These damping elements are used in place of simple tool exten-sions and ensure stable tool ratios up to a length/diameter ratio of 8xD for aluminium, cast iron and steel materials. The damping elements are optimised for the whole range of precision drilling systems from the KOMET GROUP®. When used for longer holes, they increase drilling quality, tool life and ultimately process reliability.
