Easy clamping with 600 UK's Gripfast Combination power chuck

Added to MTDCNC by 600 UK on 30 March 2015

The new Gripfast combination power chuck system from Pratt Burnerd International is an innovative new chuck line that offers quick-change jaws for maximum versatility and minimum downtime. The impressive new chuck can have the three jaws rapidly removed and replaced with an alternate set, with just the turn of one key on the circumference of the chuck.

By offering MTD a demonstration, Pratt Burnerd highlighted how the chuck jaws on the Gripfast system can be interchanged in less than 40 seconds, taking the turning centre from an external gripping to an internal clamping position in an astoundingly fast time. This highlights the potential benefits to manufacturers that are continually turning a wide variety of parts. Taking flexibility a step further, the Gripfast can also work with a mandrel for clamping on internal diameters whilst grip pads are also available for machining on particularly small work pieces.

For precision purposes, the Gripfast also has a 'setrite' feature on the circumference, so the operator can manually adjust the chuck to ensure it runs completely concentric and true. The new Gripfast system also has a counter-balance system integrated in to the chuck to ensure that chuck gripping pressure is always maintained at the highest possible clamping forces.

The new chuck is available in a variety of sizes that range from as small as 160mm for the smallest turning centres and it ranges up to a diameter of 610mm for high powered gripping of large components. The Gripfast line is not restricted to only Colchester or Harrison lathes from 600 UK with adaptor plates available to ensure the unique new line can be applied to any CNC turning centre.
