Live Center: Rotating Support for Machining Operations

This page provides an overview of live centers, precision tools used in lathes and milling machines to support the free end of long workpieces during machining. Unlike dead centers, live centers rotate with the workpiece, reducing friction and heat. Topics include their design (e.g., Morse taper shank, ball bearing interior), applications in turning/grinding, and benefits like improved accuracy and workpiece stability.

Advantages of the product

Precision Alignment

Ground tips (runout ≤0.002mm) ensure concentricity, critical for components requiring tight dimensional tolerances (e.g., turbine rotors, optical lens shafts). Complies with ISO 2338 standards for center accuracy.

Light duty live centers, as the name suggests, are intended for low-force exercises like small scale lathes. These have aluminum or steel casings and can take on speeds up to 3000rpm with the help of graphite-impregnated bearings. They can manage a maximum workpiece diameter of 50mm, thus perfectly suited for educational and hobbyist labs dealing with machining plastic and brass. The removable tip, with an option of replaceable carbide, offers easy servicing. Tolerance for total indicator runout (TIR) is set to ≤ 0.01mm which makes basic turning operations feasible.

Frequently Asked Questions

Are live centers low maintenance?

Sealed cartridge bearings and labyrinth seals resist coolant/debris, requiring no regular lubrication and extending bearing life to 20,000+ hours in harsh environments.
