Which KM Backend?

KM Mechanism The KM Quick Change clamp is a self-locking system with a mechanical When in the locked position, there is increased interference between contact amplification of 3:1 to 7:1. This system is effective because it locks by having surfaces, resulting in superior rigidity. Because the face and taper contact three contact areas, and the mechanism is sealed with Viton® O-rings to within the unit is simultaneous, this provides accurate radial and axial prevent component contamination. repeatability. Elastic deformation provides greater static and dynamic stiffness.
