The fully automatic grinding SCHUNK chuck PRISMO3 is an accurate all-rounder for automated production grinding and sharpening tools. Per direct voltage, ie without the use of collets or intermediate sleeves, SCHUNK PRISMO3 clamped on the fly continuously every shank diameter between 3 mm and 20 mm. The repeat accuracy is permanently ≤ 0.005 mm, concentricity ≤ 0.01 mm with an unclamping of 45 mm. During the clamping operation of the tool shaft is automatically centered in the chuck. An optimized interference contour ensures that the grinding wheel can flow unimpeded even in demanding operations. Compared to conventional multigrade grinding chucks the set-up time is reduced by up to 75%. In addition, users can save the investment in intermediate sleeves and collets. Since the X-axis independent of the tool diameter always remains the same, ie all jaws persist on the identical axial position, diverse drilling, reaming and milling tools can be processed unmanned also in small numbers around the clock without reprogramming the L1 dimension. Consuming additional programming and the danger of a crash because of an unrecognized axis shift are a thing of the past.

Compact dimensions and robust construction

The construction, the basic sleeve and the robust construction make the food a very high rigidity. His stable jaw guides prevent the swinging of the grinding wheels and prevent wobble almost completely. The jaws are hard-coated and thus particularly robust and durable. Should it be damaged, can completely replace the jaw set. To avoid contamination and to maintain the high precision permanently, the feed is rinsed during the grinding operation with clean oil. Whether Axial clamping cylinder, radial front finished feed or individual machine interface: SCHUNK PRISMO3 is compatible with the grinding of all renowned manufacturers. Compact dimensions of 125 mm x 125 mm can be plenty of space for tools, the grinding process and the loading. The precision grinding feed is now available.
