Description

Jaw boring rings (soft jaw truing rings) are manufactured from high-strength alloy steel with overall quenching treatment, the essential tool for precision machining with soft jaws on hydraulic power chucks.
  1. Integrated annular structure provides excellent rigidity and vibration damping, ensuring stable and accurate boring operation without deformation.
  2. Three adjustable slot design allows flexible positioning, perfectly compatible with 5-15 inch all mainstream 3-jaw hydraulic power chucks on the market.
  3. Eliminates jaw installation errors and ensures ≤0.01mm coaxiality of three jaws after truing, guaranteeing high-precision workpiece clamping.
  4. Comes with high-strength mounting bolts for quick and easy installation, can be reused multiple times for long-term cost savings.
  5. Surface anti-rust treatment ensures long service life even in harsh workshop environments.
  6. Standard dimensions match all common soft jaw specifications, no modification required for use.
