The PGU 9500 clamping unit is perfectly compatible with the highly precise powRgrip tool clamping system. At the press of a button, it clamps drilling and milling tools ranging in diameter from 0.2 to 25.4 mm in less than 10 seconds. To do so, the operator just has to select the matching clamping adapter, then insert the tool with the toolholder into the clamping unit. Toolholders are available in all standard market spindle interfaces, such as SK, HSK, BT, BT+ and Capto. On the clamping adapter selected, the PGU 9500 clamping unit automatically recognizes the right clamping pressure for the toolholder and the tool.
The particular benefits of the powRgrip clamping system include outstanding vibration damping thanks to two interfacing surfaces, the optimal T.I.R. of the clamped tools of less than 3 µm – which is still intact after more than 20,000 tool changes – as well as the exact 0.01 mm default setting of the tools to be clamped against an adjustable length stop. This contributes to long tool service life. With a very high transferrable torque of much more than 1000 Nm (PG 32), the powRgrip clamps tools made of solid carbide and HSS with cylindrical tool shanks – also Weldon and Whistle Notch toolholders – for an h6 tolerance or also thread taps and thread forms for an h9 tolerance. The clamping system therefore functions purely mechanically without heat. When clamping tools, this ensures the highest process reliability without waiting times. Tools clamped with powRgrip are suitable for challenging HSC and HPC high-speed machining.
A few weeks ago, the PGU 9500 automatic clamping unit was honored with the “Red Dot Award 2015” in the “industrial design” category. Its well-thought-out design and its particularly comfortable handling impressed the jury.
