Spotlight

  • Automation in Manufacturing


    We constantly evaluate our manufacturing process and try to optimize the cycle time, while maintaining the top notch quality of our retention knob. Automation in manufacturing process has been a game changer in our industry and we are able to make things faster and more accurate. By integrating the Marposs Unimarr measurement head into the retention knob's grinding process, we are able to monitor key dimensions on EACH retention knob, and the productivity of a CNC grinder is maximized with the robotic arm to automatically load and unload retention knob stock into the CNC grinder. We are passionately chasing speed and accuracy, and that is how we can maintain our competitive edge.

  • Concentricity


    Concentricity is inspected with a Mahr Millimess 1003 Dial Comparator which has a 1 micron (um) graduation and 0.5 micron (um) repeatability to ensure each batch production of the retention knob is true to the spindle center line.

  • Optical Measurement


    A critical dimension on every retention knob is the height of the loading contact point and the height of un-loading contact point. When these two dimensions are not within tolerance, there could lead to improper engagement with main spindle and even cause severe damage to the retention knob's rigidity. These two dimensions are inspected on an optical tool presetter that is made in Italy by a world-renowned manufacturer and measurements are monitored in micron (um).

 

  • Made from alloy steel 5155 with heat treat to RC 56-58
  • Each retention knob is individually magnetic particle tested to ensure free of crack
  • High quality black oxide finish to ensure long enduring tool life
  • Fully ground on all critical surface including a pilot under the flange of retention knob for full contact between tool holder's taper end and retention knob
