Supplier's note

  1. Three Technical Breakthroughs:

    • Hydraulic Clamping: Achieves 20% faster tool changes compared to mechanical chucks, reducing downtime.
    • Multi-Standard Compatibility: Supports BT, CAT, and HSK tapers, eliminating the need for adapter sleeves.
    • Precision Collar Design: Reduces tool runout by 40%, ensuring consistent surface finishes.

  2. Optimal Version Selection:

    • Base Model: Suitable for general milling workshops needing cost-effective performance (e.g., small-scale job shops).
    • Advanced Model: Ideal for medium-to-heavy-duty applications requiring higher RPMs and clamping force (e.g., aerospace component fabrication).
    • Pro Model: Tailored for high-precision industries like medical device manufacturing, where micron-level accuracy and extreme RPM stability are critical.

With hydraulic clamping technology, you can achieve precise tool alignment for complex geometries. The Pro version’s tripled clamping force compared to industry benchmarks ensures secure retention of delicate cutting tools during high-speed operations. Pair this with its stainless steel collar for corrosion resistance in humid machining environments.
