A new line of quick change collet chucks from Rohm Products America enables manufacturers to accomplish collet changes in seconds.
Each collet consists of three segments separated by rubber joints. Holes in the collet align with pins on the pistol-grip changing fixture. Squeezing the trigger on the fixture with one hand compresses the joints and enables the collet to fit quickly and easily into the collet chuck to drastically reduce setup times. When the fixture releases the collet, the collet expands to lock securely into the chuck. Unlike traditional spring grip collets, the quick-change collets provide grip along their entire length and ultra-precision accuracy of 0.0002 in. TIR or better.
Industry standard collets in smooth and serrated bore styles, are available, in versions to accommodate inch sizes from 7/32 in. to 1 5/8” (in 1/16 in. increments) and 1/4 in. to 2 9/16 in. (in 1/16 in. increments). Metric, hex and square sizes are quoted upon request. The Collets are available at Amazon.com.
