Stationary jaw chucks are an essential tool in manufacturing, particularly in drilling and milling environments. Enabling workpieces to be stably secured, Birmingham-based Norelem’s range includes three-jaw and four-jaw stationary chucks made of steel for optimum performance.

Providing stability to the workpiece, parts being machined can be clamped between clamping jaws, while the drill chuck holds the tool in place — a factor which is particularly important for fast-moving machines to ensure precision and safety.

The stationary three-jaw chuck from Norelem enables round, triangular or hexagonal workpieces to be securely clamped when carrying out drilling, milling or grinding tasks. Alternatively, a four-jaw stationary chuck can be used to clamp a variety of other shapes, including four-, eight- and 12-sided workpieces.

The flexible arrangement of the clamping jaws in hard and soft design allows workpieces of different sizes and shapes to be easily clamped from the inside or outside using a hexagonal wrench. To create a synchronous movement of the clamping jaws and ensure consistent clamping force, a slewing ring located in the chuck and the rotational movement of the threaded spindle, creates a moveable base for the jaws to operate. To maintain reliable function and clamping force, regular lubrication of the components is essential via the optimally positioned lubrication system.

Centric clamping
Quick and easy to operate, Norelem jaw chucks have a flat design and a large through-hole for clamping bar material. The base body of the jaw chucks is made of ground steel, as are the clamping jaws which use hardened and ground steel, enabling a repeatability of 0.02mm in centric clamping. Soft jaws can also be screwed onto the base jaws to generate individual clamping contours and diameters.

Stationary three-jaw chucks are available in four different diameters from 220 to 370mm and can achieve a clamping force of up to 44kN. Stationary four-jaw chucks are available in four different sizes with a width of 215 to 380mm, with a clamping force of up to 25kN.

Every success starts with an idea. That is why Norelem supports designers and technicians in mechanical and plant engineering in achieving their goals, with the right solutions for every job available in THE BIG GREEN BOOK – norelem’s unique and easy-to-use product catalogue which has thousands of products immediately available.

Visitors to Subcon 2024, which takes place 5-6 June at the NEC, Birmingham, can see Norelem’s products up close and talk to its dedicated product team (Stand A61).
