Shanghai Stefor Technology Co., Ltd

Tool Holder

Premium Alloy Steel Selection: Crafted from high-strength alloy tool steels such as 20CrMnTi or 40Cr with integrated forging processes, ensuring exceptional structural stability and superior core toughness. Ultra-Precision Grinding Technology: Core components are processed using advanced ultra-precision grinding, maintaining a radial runout strictly within 0.003mm – 0.005mm to provide ultimate accuracy for demanding machining tasks. Advanced Heat Treatment & Hardness Balance: Features precision carburizing or induction quenching to achieve a surface hardness of HRC 58-62, delivering maximum wear resistance while maintaining core flexibility for heavy-duty cutting. High-Speed Dynamic Balancing: Supports high-spec dynamic balancing (up to G2.5 / 25,000 RPM), significantly suppressing vibration at high speeds to protect the machine spindle and enhance surface finish. Excellent Rust and Corrosion Resistance: Finished with eco-friendly anti-rust coatings, black oxide, or specialized plating, ensuring long-lasting precision and a professional appearance even in constant contact with cutting fluids. Superior Clamping Torque Design: An optimized internal clamping structure provides high radial torque, preventing tool slippage during heavy-duty or interrupted cutting operations for safer and more stable machining. International Standard Compatibility: Fully compliant with global standards including ISO, BT, SK, HSK, and MT, ensuring 100% precise compatibility with mainstream CNC machining centers and manual lathes worldwide. Efficient Tool Changes and Positioning: A human-centric modular design significantly reduces setup and tool alignment times, boosting overall production line utilization and lowering operational costs. Full Sealing Against Dust and Coolant: Key interfaces are equipped with precision O-rings or labyrinth seal designs to prevent metal chips and coolant from penetrating the internal mechanism, ensuring long-term reliability. Comprehensive Process Coverage: Offers a full range of solutions—from precision tool holders and elastic collets to live centers—catering to diverse industrial applications from rough machining to ultra-fine finishing.
