Lathe Chuck: Precision Workholding Device for Lathes

This page introduces lathe chucks, essential workholding devices for lathes that securely clamp workpieces during machining. Typically made of durable cast iron or steel, they feature jaws (e.g., three-jaw, four-jaw) to grip cylindrical or irregular shapes. Topics include chuck types, clamping mechanisms, applications in turning operations, and key performance factors like concentricity and clamping force.

Advantages of the product

Heavy-Duty Construction

Cast iron or alloy steel bodies (yield strength ≥800MPa) and hardened jaws (58-62HRC) withstand clamping forces up to 200kN. Suitable for rough machining of cast iron and Inconel in heavy equipment manufacturing.

Related products

4 jaw lathe chucks have four independent adjustable jaws and can be used for more complex workpieces like square bars or camshafts. Each jaw can be moved with an individual screw which permits precise alignment (centering accuracy ±0.005mm via dial indicator) for sophisticated geometries. Heavy-duty versions with soft/hard reversible jaws are used in rough machining and finish turning, standard in tool and custom fabrication shops.

Frequently Asked Questions

How do quick-change jaws work?

Interchangeable soft jaws (aluminum/copper) protect delicate surfaces, while hard jaws handle aggressive cutting, reducing tool change time by 40% in mixed-material setups.
