REGO-FIX Tool Corp.will showcase the benefits of its powRgrip toolholding collet system at WESTEC 2017. The company says that visitors can see how the system generates clamping forces equally as strong, if not stronger, than shrink-fit holders.

The powRgrip system is a collet-holding system that consists of three main components—holder, collet and press fit assembly mounting unit—that work together to generate what Rego-Fix describes as superior clamping force, high-vibration dampening and extreme precision. Unlike other clamping systems for which heat or hydraulics are used to expand the material, the powRgrip uses the mechanical properties of the holder material to generate gripping force with tool run-out below 0.0001". Interchangeable collets are available from 0.125-1.000". They are available in metric sizes as well, and they hold both carbide and high speed steel tools.

The powRgrip system takes less than 10 seconds to press in a tool or to remove a tool from the holder. Because the system does not rely on heat, machinists can use the tools immediately after a tool change. Cycle testing of the system exceeded 20,000 insertions and removals. The powRgrip product line offers several ancillary technologies and accessories. Large powRgrip PG 32 collets are especially well suited for machining components that are made from Inconel and titanium. The large powRgrip PG 32 collets are also well suited for Rego-Fix secuRgrip technology, which combines powRgrip’s gripping strength with a patented locking key system. Rego-Fix says this gives machinists an added degree of confidence for applications like heavy-duty material removal and the machining of expensive castings or complex parts.

Xtended Length Toolholders also enable operators to tackle machining applications that require longer reach or present clearance challenges. Likewise, computer, communication and consumer electronics manufacturers can tackle the specific demands of small complex parts and molds with the slim-nose PG6 toolholders. These toolholders enable machinists to access difficult-to-reach features when drilling or milling.
