Spindle Connection, KM4X100

---

Kennametal has introduced robust Spindle Connection, KM4X100™, which provides three times greater bending moment resistance for improved milling, turning, and holemaking. This spindle connection helps deliver maximum machine tool power for maximum metal removal in titanium and hard alloys. The spindle connection is the “handshake” – the interface between the machine tool’s spindle and toolholder. As such, this vital component has to provide the torque and bending load capacity compatible with the machine-tool’s operating specifications. But when machining high-strength materials like titanium and other alloys, cutting forces generate bending moments that will exceed the interface’s limits prior to reaching the machine tool’s torque threshold. By combining high clamping force and optimised interference levels, Kennametal’s new KM4X100™ provides a robust connection, extremely high stiffness, and bending load capacity for greatly improved performance in machining high-strength alloys and other materials. By using three-surface contact for improved stability and optimised clamping force distribution and interference fit, KM4X100™’s engineering results in three times the bending moment resistant capacity compared to other tool systems.
Benefits, in a nutshell are:

• Increase speeds and feeds in difficult machining applications, thus gaining the full productivity potential from the machine tool
• Smaller connection can provide the same or better cutting performance of a larger connection
• Can be applied on multi-tasking, turning, machining centres and transfer machines in manual, semiautomatic, or fully automatic mode
