Preset ER Collet Torque Wrenches

​"Variable Processes produce Variable Results" My favorite quote from Dr. Scott Smith of UNC Charlotte. If you want to create a truly lean, repeatable and error free process you must eliminate variability. Single purpose and preset. One product that can benefit from this is the very popular ER collet chuck. An ER spring collet is indeed a spring. If you drop one it will bounce. Like any spring, its properties change with how tight you compress it. If you under-tighten the collet the tool may slip or pull out. If you over-tighten the collet it will twist and distort the shank angle creating runout. Dynamically, the stiffness and damping properties of the tool assembly change with the collet torque, thereby changing the location of stable speed lobes. Yet, you rarely see users torque collet chucks. Recently when searching the internet, I came across this product from a company called the iSWISS CORPORATION. These are preset torque wrenches, one for each ER collet nut type (spanner and hex). They are inexpensive and with nothing to adjust and no socket to change, all variability, all chance for error have been removed. Find them here: https://lnkd.in/dSAVNc2
