Technical Information KM4X™ KM4X — The Next Generation Spindle Connection System As a global tooling supplier and a true customer support partner, we recognize the need to offer tooling products for all spindle interfaces and make available solutions to provide the best cutting edges to gain maximum productivity at the spindle system connection. KM4X is the latest version of the KM™ spindle interface targeted at heavy-duty machining operations and is a top choice for machining large, structural tough-to-machine materials like titanium for the aerospace industry. The Latest Innovation in Spindle Interface Technology • KM4X offers the most rigid connection able to withstand extremely high bending due to a combination of high interference and high clamping forces. • KM4X provides 3x more bending capacity than comparable face contact systems. • KM is the only connection that maintains stiffness at elevated rotational speeds and is suitable for a range of applications from low speeds with high torque to very high spindle speeds with low torque. • KM4X maintains a better balance between bending and torsion capabilities. • The ability to retrofit KM4X to an existing machine tool offers the added advantage of increasing throughput. • Heavy-duty, rigid configuration with evenly distributed clamping force. • Simple design enables front-loaded spindle configuration. • Balanced-by-design for high spindle speed capacity. KM4X three-surface contact for improved stability and accuracy. Optimized clamping force distribution and interference fit provides higher stiffness. WWW.WIDIA.COM K7 Technical Information
