“Anti-Pull” Device Blocks Cutter Pullout

TIR of 0.0001-in. lets manufacturers to preset tool heights No specially modified endmills required

A new “anti-pull” system that locks a collet and cutter to a toolholder body eliminates cutter slippage during demanding metal removal, so that the only possible failure mode is that of the cutting tool.  The new secuRgrip device was introduced at IMTS 2012 by Rego-Fix as a new feature of its powRgrip product series.

The full powRgrip series includes holders, collets and a mini-press. The secuRgrip works by using the powRgrip’s considerable gripping strength in conjunction with a patented locking system and threaded cap.

With the increased cutting tool security that secuRgrip establishes, manufacturers (especially in the aerospace sector, according to the developer) can have greater confidence when machining expensive castings or materials. Rego-Fix indicated it developed the secuRgrip system in response to customer demand for a fail-safe system.

The secuRgrip system has a TIR of 0.0001-in. that allows manufacturers to preset tool heights. Rego-Fix customers can modify their existing powRgrip holders for use with the system. 

David McHenry, senior product engineer, indicated that even with the highest clamping forces in the industry there are still applications that require additional safety measures.

Unlike other systems, secuRgrip does not require the purchase of specially modified endmills: rather, it makes use of standard carbide or HSS endmill designs. Standard ground notches found on most Weldon-type endmills will accept the locking key insert of the secuRgrip system for fast and easy assembling.

The secuRgrip system assembles quickly by placing the small, profiled locking key insert into the flat of an industry-standard Weldon-type endmill. Then, the endmill is screwed into a collet with the same thread pattern. Next, the collet assembly is securely and accurately pressed together using the powRgrip mini-press before a small retaining cap is added to the outside of the holder to secure the collet to the holder.

The secuRgrip system is applicable for use with Rego-Fix PG 25 or PG 32 holders in all tapers, including CAT, BT, TC, HSK, CAPTO and dual-contact Rego Plus.
