Spotlight

  • Dynamic Balancing

    Tool holder is balanced to G2.5 20,000 RPM on a HAIMER Tool Dynamic Balancing System from Germany.  Balanced tool holder minimizes the centrifugal forces which minimize the stress on spindle bearing, minimize vibration and maximize the cutting tool's life cycle and greatly improve surface finish. 

  • Pre-Balance Design

    Unique design feature in the extension nose to minimize the off-balance nature of CAT 40 taper specification.  On the side of flange where a half spherical hole is located, a flat is cut into the cylinder nose to compensate the weight of the metal chips lost from forming this spherical hole.  And when the holder is placed into the Haimer balance machine, less holes would need to be drilled in the v groove of the flange to protect the rigidity of the tool holder. Evenly weight distribution will minimize centrifugal force in high speed spinning and thus maximize the holder's ability to hold the cutting tool concentric to spindle rotation.
