Self-centring power chucks

Self-centring power chucks for machine tools or machining centers

Self-centering chucks are clamping and locking tools used on conventional lathes, horizontal and vertical lathes, CNC lathes, machining centers, milling machines and rotary tables. They are employed for drilling, turning and grooving operations, ensuring a secure and stable grip even on large and heavy workpieces. Self-centering chucks for lathes guarantee reliability, durability and precision—essential characteristics for high-quality rotary machining. They are ideal for machining round parts made from various materials and are designed to operate continuously even under intensive conditions.

Available in 2-, 3-, 4- and 6-jaw versions, self-centering chucks adapt to all production needs, from gripping irregular or delicate components to machining standard parts with high repeatability. Automatic models excel in providing fully machine-controlled jaw opening and closing via hydraulic or pneumatic cylinders. This system enhances efficiency, safety and operational speed. Manual models, on the other hand, offer a robust, straightforward and reliable solution, well suited for traditional machining or toolmaking. The chuck body, typically made of steel, is engineered for maximum durability, optimal accessibility and low inertia. An outer flange for coolant ejection helps maintain ideal operational conditions during machining.

Beyond high-end machine tool models, there are self-centering chucks compatible with specific equipment such as HOLZSTAR woodworking machines, OPTIMUM lathes and LTF-branded machinery. These solutions broaden the range of applications and enable self-centering chuck technology to be extended into cross-industry areas, consistently ensuring high precision and operational reliability.

Self-centering chucks produced by RÖHM are utilized in numerous industrial and craft sectors. Industry and craftsmanship have relied for over a century on advanced, robust, and long-lasting tools. The automotive industry requires secure clamping solutions for every component, using hydraulic, pneumatic or electric clamping systems.
