Product Spotlight

  • Dual Contact

    With simultaneous contact on taper and flange face between the spindle and tool holder, dual contact tooling eliminates the 1/8” gap between the flange face and the spindle nose to increase rigidity, minimize vibration, extend cutting tool tool life, and greatly improve workpiece surface finish at aggressive speed & feed


    By utilizing DONE IN ONE capability from Mazak Integrex machine with a second turning spindle, all processes from raw bar stock material to final machining in just one machine to improve machining accuracy and streamline production output.

  • Mirror Finish

    To achieve AT3 or better taper contact as an industry standard, our taper surface are precision ground on Shigiya CNC grinder from Japan and taper accuracy is inspected in Mahr air gage. We are not satisfied with just meeting the industry standard, the surface roughness on the taper is maintained to mirror finish.

  • Flange and V-groove are precision ground to ensure reliable tool change
  • Spindle Thru coolant capability
  • SHARS Dual Contact tool holder can only be used on machine center with dual contact spindle
