A Revolving Centre, also known as a Live Centre, is a lathe tool used to support the free end of a rotating workpiece during machining. Unlike a dead centre, it has internal bearings that allow it to rotate with the workpiece, reducing friction and preventing heat buildup.

Types of Revolving Centres

• Standard Revolving Centre – General-purpose centre for most turning applications
• Heavy-Duty Revolving Centre – Designed for high-load and high-speed operations
• Interchangeable Tip Revolving Centre – Features replaceable tips for different workpiece types
• Extended Nose Revolving Centre – Provides extra reach for deep machining operations
• High-Precision Revolving Centre – Used in CNC and precision turning applications

Size Range

• Available in Morse Taper (MT1 to MT6) and other standard tapers
• Various load capacities for different machining needs

Features

• Hardened and precision-ground body for durability and accuracy
• High-quality bearings for smooth rotation and minimal runout
• Reduces workpiece deflection and vibration for better surface finish
• Available with different nose designs (standard, extended, or interchangeable tips)

Applications

• Used in lathe machines for turning, grinding, and facing operations
• Ideal for CNC and manual machining in metalworking industries
• Supports long and slender workpieces to prevent bending and chatter

Revolving Centres provide excellent support and stability in machining, improving accuracy, surface finish, and tool life.
