Hardinge Inc., renowned globally as the leading producer of spindle tooling solutions, has just unveiled their latest innovation: the 80mm FlexCâ„¢ vulcanized collet system. Designed for maximum efficiency, these collet chucks can be directly mounted onto the machine spindle. The 80mm vulcanized collets are easily inserted and removed using a manual compression wrench, completing the process in under ten seconds. This is a remarkable eight times faster than replacing a collet in a standard collet chuck and an impressive nineteen times quicker than swapping out three jaws on a jaw chuck.
While rapid changeover is certainly one of its standout features, the FlexC collet system also excels in precision. Classified under "special accuracy" collets, it guarantees a tolerance of .0004" (.010mm) TIR for style A (pull-back Dead-length® stationary stop) and .0008" (.020mm) TIR for style DL (push-to-close). Despite offering the same gripping strength as traditional collets, it requires less draw bar force. Furthermore, the collet head boasts a gripping range of ±.020" (.5mm) around its nominal size, allowing for variations in bar stock without needing to switch collets. Without a collet body, the segments remain parallel to the stock, ensuring full bearing contact with the workpiece for enhanced holding power and reduced pushback.
In comparison to 3-jaw chucks, the Hardinge FlexC collet system is lighter, has a lower profile, and transitions between setups much more swiftly. It is fully compatible with other brands on the market, making it a versatile choice. Consider the FlexC collet system for specialized accuracy needs or mount it on a chuck-style lathe or rotary indexer for added flexibility. Available options include round and hex smooth, round and hex serrated, square smooth, emergency, and S-master styles.
Michael Levanduski, Sales Manager at Hardinge Workholding, commented, "Our Hardinge FlexC Collet Systems are perfectly suited for job shops that undergo numerous changeovers daily. Test results confirm that our FlexC 80 quick-change vulcanized collet system offers customers a highly durable, fully sealed, and precise gripping solution. We're thrilled to expand our product line to accommodate machines with 42mm, 65mm, and 80mm specifications."
