ULTRA PRECISION

ULTRA PRECISION 

METRIC / INCH - ULTRA PRECISION

TECHNICAL FEATURES

  • • Manufactured in spring steel
  • • Grounded both externally and internally;
  • • After this operation there is an additional phase of finishing, which guarantees a grade of roughness lower than Rz 2,5.
  • • Quenched and tempered, HRC 45+2
  • • Concentricity precision: 0.005 guarantee only for the nominal diameter
  • • Clamping range 0.5
