Rigid Spindle Connection Increases Metal Removal Rates Machine Too Utilization, Reduces Part Cost

Haimer USA (Vila Park, IL) provides Kennametal’s new and advanced KM4X spindle connection that enables manufacturing companies to maximize their capital investments, achieve higher metal removal rates and machine tool utilization, and reduces cost per part while increasing available capacity.

New high-strength, lightweight titanium alloys, Inconel, and new aluminium alloys present significant machining challenges that make rigid toolholding critical. The spindle connection, the interface between the machine tool’s spindle and toolholder, must provide the torque and bending load capacity compatible with machine-tool specifications.

Cutting forces, particularly in roughing or machining high-strength materials, generate bending moments that will exceed the interface’s limits prior to reaching torque limits.

By combining high clamping force and optimized interference levels, KM4X provides a robust connection, extremely high stiffness, and bending load capacity for greatly improved performance in machining high-strength alloys and other materials. This means extremely high metal removal rates and more completed parts per day.

The KM4X spindle connection makes it possible to utilize the full potential of Haimer toolholders. Outdated dual-faced steep-taper systems limit the potential of modern machine tools. The KM4X spindle connection is the leading interface for the high-torque, high-rpm fine balanced toolholders that Haimer provides to achieve maximum potential of machine tools.
