The TRIBOS-RM polygonal spindle in the HSK-E DIN 69893-5 version represents an advanced solution for high-speed cutting (HSC) operations in micro-machining, designed to operate at speeds up to 85,000 rpm and beyond. Its extremely robust construction and symmetrical rotation design ensure rigidity and uniform motion, essential conditions for metal cutting processes where precision and reliability are critical. The run-out accuracy of less than 0.003 mm at 2.5 times the tool diameter minimizes vibrations and deflection, enabling high-quality surface finishes even on small components or complex geometries.

The TRIBOS-RM spindle features an HSK-E interface compliant with DIN 69893-5, providing compatibility with high-quality h6 tool shanks. Its high balancing grade, G2.5 at 25,000 rpm or Umax < 1 gmm, allows operation at high speeds without compromising cutting stability or tool life. Tool holder replacement can be automated, facilitating integration into highly dynamic machining centers and reducing machine downtime. Coolant supply is not provided via threaded transmission tubes, while the absence of an axial adjustment screw keeps the tool position stable, simplifying maintenance and reducing the risk of setup errors.

TRIBOS-RM is particularly suitable for applications in aerospace, automotive, watchmaking, and precision component manufacturing, where hard metal alloys must be machined to tight tolerances with excellent surface finishes. The availability of various sizes ensures perfect adaptation even to small machining centers, delivering high performance on compact machines. In summary, TRIBOS-RM combines precision, structural rigidity, optimal balancing, and HSK-E compatibility to provide a reliable and efficient solution for ultra-high-speed micro-machining, with constant focus on part quality and process efficiency.
