DESCRIPTION
Live centers are tools used to support and stabilize a rotating workpiece during machining on a lathe. Unlike static centers (dead centers), live centers feature bearings that allow them to rotate along with the workpiece, reducing friction and wear.
Design and Construction:
Consist of a tapered tip that fits into the center hole of the workpiece.
Include high-precision bearings for smooth rotation.
The body is often made of high-strength steel or other wear-resistant alloys.
Cone Shapes and Types:
Available with various cone angles (commonly 60°) depending on the application.
Some models feature replaceable tips or specialized profiles for specific machining tasks.
Mounting Types:
Live centers have a shank that fits into the lathe tailstock or turret, typically with a standard taper (e.g., Morse Taper).
Applications:
Support for Large or Long Workpieces:
Used to support shafts, pipes, or parts that require stability during rotation.
Precision Machining:
Prevent vibrations or bending, ensuring accurate machining.
High-Speed Operations:
Ideal for applications requiring high cutting speeds without excessive heat or wear.
Specialized Machining:
Certain live centers are designed for specific tasks, such as supporting pipes or holding tapered surfaces.
