Schunk Prismo3 toolholder suits automated grinding
The latest generation of Schunk Prismo toolholders has been developed to provide greater efficiency during production tool grinding. This is because the Prismo3 clamps every shank diameter between 3 and 20 mm automatically without using collet chucks or intermediate sleeves at a run-out and repeat accuracy of less than 0.005 mm, says Schunk.
The tool shank is centered automatically in the toolholder during the clamping operation, while an optimised interfering contour ensures better interference between the grinding wheel and the toolholder, even in demanding operations, says the company. Compared with conventional, multi-range grinding toolholders, the set-up time with the Prismo 3 is said to be reduced by up to 70%. Moreover, users don't have to invest in intermediate sleeves and collet chucks.
Since the X-axis is independent from the tool diameter and does not change, every type of chuck jaw can remain in the same axial position, which allows unmanned machining.
