Kennametal announces breakthrough spindle connection

Spindle connection helps deliver maximum machine tool power for maximum metal removal in titanium and hard alloys. The spindle connection is 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.

Kennametal’s robust KM4X100™ spindle connection provides three times greater bending moment resistance for improved milling, turning, and holemaking.

When machining high-strength materials like titanium and other alloys, cutting forces generate bending moments that may exceed the interface’s limits prior to reaching the machine tool’s torque threshold. By combining high clamping force and optimized 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.

To use machines at full capacity
“In most cases, the tool-spindle connection determines how much material can be removed on a given operation,” says Doug Ewald, director, global product management, tooling systems at Kennametal. “This is because this interface must withstand high loads and yet maintain its rigidity. With the ongoing advances in cutting tools and machining centers, a spindle connection like KM4X 100™ that makes the best utilization of available power possible is an important consideration to investigate early in production planning.”

A few assets
By using three-surface contact for improved stability and optimized clamping force distribution and interference fit, KM4X100™’s engineering results in three times the bending moment resistant capacity compared to other tool systems. This means:

  • Shops can leverage KM4X-equipped high-performance machine tools to increase speeds and feeds in difficult machining applications, thus gaining the full productivity potential from the machine tool.
  • Often, a smaller KM4X connection such as a KM4X100™ will provide the same or better cutting performance of a larger connection.
  • KM4X systems can be applied on multi-tasking, turning, machining centers and transfer machines in manual, semiautomatic, or fully automatic mode.
