Kennametal Technical Information KM Clamping Systems Rapid Clamping System Characteristics KM Rapid is a compact quick-change clamping system providing outstanding repeatability while, at the same time, allowing fast manual locking and unlocking. KM cutting units are locked and unlocked with only a 115° turn of the actuation cam with no torque wrench required for clamping and unclamping. A stop pin limits the angle of rotation, and actuation is available from the side only. The KM Rapid, with internal through-the-tool coolant capabilities, is best used in stationary applications on turning centers in high-volume production. KM Rapid permits the external installation of an orientation screw to restrict the clamping unit to accept the cutting unit in only one orientation. Rapid Plus Clamping System Characteristics The KM Rapid Plus clamping system provides approximately 20% more locating face force versus the KM Rapid. It is designed for retrofitting in dedicated applications enabling cutting units to be locked and unlocked with only a 180° turn of the actuation cam. Actuation is available from the top only. The Rapid Plus cartridge design allows use in smaller but slightly longer receivers, such as Multifix and Parat adapters. Automatic Clamping System Spring-Pack Activated Characteristics Automatic KM clamping systems enable tools to be locked or unlocked with the push of a button by the machine operator or changed automatically by the machine tool. These units also allow tools to be changed quickly and provide a high level of automation at a moderate cost. Operation The pull on the lock rod for the automatic KM clamping unit is provided by disk springs that are an integral part of the clamping unit. Release is accomplished by pushing on the back of the clamping unit with a hydraulic cylinder mounted on the turret assembly. Many machine tool builders design and build the turrets for their machines to be equipped with the KM Automatic Clamping Units. KM Rapid offers two main standard styles: Flange mount holders, fastening with four socket head cap screws and an additional orientation pin, can be used on turrets axially or radially. VDI shank tool holders, according to DIN 69880, in axial and right-angle styles for I.D. and O.D. turning applications. Kennametal M21 Technical Information
