Rapid Clamping System<br />
Characteristics<br />
KM Rapid is a compact quick-change clamping system providing outstanding<br />
repeatability while, at the same time, allowing fast manual locking and unlocking.<br />
KM cutting units are locked and unlocked with only a 115º turn of the actuation<br />
cam with no torque wrench required for clamping and unclamping. A stop pin<br />
limits the angle of rotation, and actuation is available from the side only.<br />
The KM Rapid, with internal through-the-tool coolant capabilities, is best used<br />
in stationary applications on turning centers in high-volume production.<br />
KM Rapid permits the external installation of an orientation screw to restrict<br />
the clamping unit to accept the cutting unit in only one orientation.<br />
Rapid Plus Clamping System<br />
Characteristics<br />
The KM Rapid Plus clamping system provides approximately 20% more locating<br />
face force versus the KM Rapid. It is designed for retrofitting in dedicated<br />
applications enabling cutting units to be locked and unlocked with only a 180º<br />
turn of the actuation cam. Actuation is available from the top only.<br />
The Rapid Plus cartridge design allows use in smaller but slightly longer<br />
receivers, such as Multifix and Parat adapters.<br />
Automatic Clamping System • Spring-Pack Activated<br />
Characteristics<br />
Automatic KM clamping systems enable tools to be locked or unlocked with<br />
the push of a button by the machine operator or changed automatically by the<br />
machine tool. These units also allow tools to be changed quickly and provide<br />
a high level of automation at a moderate cost.<br />
Operation<br />
The pull on the lock rod for the automatic KM clamping unit is provided by disc<br />
springs that are an integral part of the clamping unit. Release is accomplished by<br />
pushing on the back of the clamping unit with a hydraulic cylinder mounted on<br />
the turret assembly. Many machine tool builders design and build the turrets for<br />
their machines to be equipped with the KM Automatic Clamping Units.<br />

KM Clamping Systems<br />
KM Rapid offers two main standard styles:<br />
• Flange mount holders, fastening with four socket head cap screws and an<br />
additional orientation pin, can be used on turrets axially or radially.<br />
• VDI shank tool holders, according to DIN 69880, in axial and right-angle styles<br />
for I.D. and O.D. turning applications.<br />
