TRIBOS polygonal toolholders

From micro to macro

TRIBOS shows its strength in highly precise micromachining right up to large volume cutting. With its patented TRIBOS polygonal clamping technology, SCHUNK offers a toolholding system that stands out due to its versatile and extensive range of applications.
Excellent concentricity properties of < 0.003 mm ensure a longer service life and the best surface qualities. TRIBOS is absolutely maintenance-free, and due to its honeycomb/anchor structure, it dampens vibrations in an ideal way. Intermediate sleeves additionally create versatile clamping ranges.

Our performance promise. Your benefits.

  • From micro to super finish machining, up to heavy-duty and volume metal cutting
  • Concentricity property < 0,003 mm
  • Absolutely maintenance-free

    TRIBOS-S

    TRIBOS-S

    Extremely slim design! Precise in the tightest machining conditions. If workpiece areas are hard to reach and conventional clamping systems have reached their limits, TRIBOS-S polygonal toolholders with their extremely slim design are the best choice.

    The highest permanent run-out and repeat accuracy of ≤ 0.003 mm ensures a more even cutting action, thereby improving the tool service life by four times over.

    TRIBOS-RM

    TRIBOS-RM

    TRIBOS-RM is suitable for powerful HSC machining in micro-cutting up to 85,000 RPM and higher. The excellent run-out accuracy of ≤ 0.003 mm as well as a stability gained from the anchor structure form the basis of the extremely compact toolholder mountings, and in so doing ensures precise and process-reliable metal cutting. The different sizes are perfectly suitable for small, highly dynamic machining centers.

    TRIBOS-Mini

    TRIBOS-Mini

    TRIBOS-Mini is setting standards in micro-cutting. This polygonal clamping system is used in filigree machining operations for housings, molds, electrodes, and engravings in medical technology and electrotechnology, as well as in the watch and clock making industry, or in the precision die construction industry. TRIBOS-Mini can be used to clamp extremely small shanks, starting at Ø 0.3 mm, which means the time-consuming and cost-intensive manufacturing of special tools is no longer needed.
