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.

Magnetic Bending Machine

Powered via electric, pneumatic, or hydraulic mechanisms, CNC lathes perform automated clamping/unclamping with power chucks. Electric models (servo-drives) enable precise control over applied forces (resolution: 10N), while pneumatic chucks are best for lightweight parts with quick cycle times (≤2s). They are commonly used in lights-out manufacturing because of their integration with machine control systems for pressure monitoring and reduction of operator involvement which increases productivity by 40%.

Frequently Asked Questions

How does chuck design ensure high-speed stability?

Balanced designs (G2.5 at 6000rpm) and low-mass aluminum bodies reduce vibration at high speeds (up to 10,000rpm), critical for aerospace and electronics components.
