Toolholder Uses Low Heat Processes

The powRgrip collet system uses a toolholder and collet to provide clamping forces equal to or greater than shrink-fit-style holders.  According to the company, the system is designed with ease of operation and functionality in mind. Less than 10 seconds are required to press in a tool or remove it from the holder.

The powRgrip collet system uses a toolholder and collet to provide clamping forces equal to or greater than shrink-fit-style holders. According to the company, the system is designed with ease of operation and functionality in mind. Less than 10 seconds are required to press in a tool or remove it from the holder. The system allows tools to be handled safely and immediately after a tool change because it does not use processes that rely on high levels of heat, says the company.

Unlike other clamping systems where heat or hydraulics are used to expand the material, this system uses the mechanical properties of the holder material to generate gripping force with a runout of less than 0.0001".

Also available is the Zero-Z short toolholder, which has a short projection that allows for more Z-axis stroke and greater workpiece size. The toolholder’s design features a flush collet nut to eliminate tool overhang.

The company’s collet system (DIN 6499) is suited for boring, milling, reaming, tapping and grinding. It is available in two levels of precision: standard and ultra-precision. Both precision levels, ranging from the ER 8 series to the ER 50 series, are available in standard and metric sizes. This selection of ER collets can accurately clamp tool shanks ranging from 0.2 mm to 34.0 mm.
