Spotlight

  • Automation in Manufacturing

    We constantly evaluate our manufacturing process and trying to optimize the cycle time while maintain 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 dimension 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 this 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. This two dimensions are inspected on an optical tool presetter that is made in Italy by a world-renowned manufacture and measurement 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

 

 

 

  • Precision finished on the bottom of the flange to improve fitting with the bottom nose of the taper on the tool holder

 

 

  • This pull stud is compatible with the following:
  • J&M JM31109C
  • Command RB2M-0002-C
