ProductDescription : 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 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. 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 SNCM420 (SAE 4320) with high nickel alloy content with heat treat to RC 56-58 Each retention knob is tested for magnetic particles individually to ensure that it is free from any defeats High quality black oxide finish to ensure long enduring tool life. Fully ground on all critical surfaces 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.
ProductDescription1 : H6 arbor tolerance to improve cutter chattering and overall cutting tool life
ProductDescription2 : T.I.R. 0.0004" measured from NMTB 30 taper to face and arbor
ProductDescription3 : Made from alloy steel harden to 54-60 HRc
ProductDescription4 : Taper ground to AT3 or better accuracy standard for maximum contact with spindle. This tool holder has used Stotz Air/Electronic Gaging for production and finish inspection. Stotz has been chosen by major aircraft companies as the best and most consistent gaging for tool holder shanks
ProductDescription5 : All critical surface are precision ground, Each holder comes with a lab certificate on its taper accuracy and runout measurement
