Description

These scroll chucks feature a spiral ring design in steel, which is a proven suitable clamping system. They can be used in applications in which there are requirements for high clamping force, repeatability, and run-out accuracy. Ideal use is on rotary tables, dividing heads, lathes, etc. With a turn of a key, the jaws can be moved across the whole clamping range. With this ability, work-pieces with different diameters can be used for clamping without the need for shifting or changing jaws. The scroll is drop-forged and hardened. In order to maintain gripping force, the lathe chucks should be lubricated regularly.
