Hard Part Reaming Tools Hard Part Reaming • Reaming in hardened Steel and HSS up to 68 HRC. • Replaces internal grinding with improved geomethry and surface nish. • Time savings of up to 90%. • Straightens holes after hardening. Internal grinding 26 minutes Hard Part Reaming 2 min 20 sec. Case study: By altering the method from internal grinding to Hard Part Reaming, in a complex workpiece with hardness 58-62 HRC, a customer reduced his machining time from 26 minutes to 2 minutes and 20 seconds. The surface nish improved from 0,6 to 0,2 Ra. Roundness was 4µ. All Hard Part Reamers have internal coolant as standard. Standard sizes are delivered preset to +0,008 mm from min. diameter tolerance H7. The standard sizes will produce holes according to the nominal diameter of the reamer and with H7 tolerance. The adjustability of the reamer can be used to increase the tolerance band or for ne-adjustment within a certain tolerance. Intermediate diameters are manufactured and preset to your requirements.
