The components are designed for manual operation and are available in four compact sizes with diameters of 50, 64, 104 and 160 mm. The bodies of the 50 mm and 64 mm chucks are made from steel, while the 104 mm and 160 mm versions are made from aluminium, so they are light and ergonomic to handle. For increased durability, the chuck’s jaws are engineered from hardened steel.
“We have added these precision three-jaw chucks to our range because we know just how important it is to be able to securely hold cylindrical workpieces easily and efficiently,” said Marcus Schneck, CEO of Norelem. “To meet this challenge, the jaws on our components are easily operable, and are opened and closed by simply rotating the clamping ring by hand or using the supplied lever.”
With a concentricity of <0.03 mm, a circular runout of <0.01 mm and a repeat clamping precision of <0.01 mm, the chucks offers excellent performance and accuracy. The hardened jaws are stepped on the internal diameter and can be reversed. To further help engineers, numbers are marked on the top and bottom of each jaw and this number must match the number marked on the matching slot on the chuck body.
