KM™ Quick Change KM4X™ Features and Benefits KM4X — The Next Generation Spindle Connection System • Heavy-duty, rigid configuration with evenly distributed clamping force. • Simple design enables front-loaded spindle configuration. • Balanced-by-design for high spindle speed capacity. • Capable of performing in a wide range of operations from low speed, high torque to high speed, low torque. KM4X three-surface contact for improved stability and accuracy. Optimized clamping force distribution and interference fit provides higher stiffness. Figure 1 represents the load capacity of HSK, PSC, and KM4X. The shaded areas achieve high-performance machining. Some systems may be able to transmit represent the typical requirements for heavy duty in various machining processes. considerable amount of torque, but the cutting forces also generate bending KM4X is the only system that can deliver the torque and bending required to moments that will exceed the interface’s limits before torque limits are exceeded.
