The most commonly used type of rotary center in machining is the Live Center
1) Dead Center:
- Description: A non-rotating center that is typically made of hardened steel.
- Function: It supports the workpiece without rotating, providing stability. Usually used at the tailstock end of a lathe.
2)Live Center:
- Description: A rotating center equipped with bearings that allow it to spin with the workpiece.
- Function: It reduces friction and allows the workpiece to turn more freely, which is beneficial for high-speed operations.
3)Semi-Live Center:
- Description: A hybrid between a dead center and a live center, often featuring limited rotation.
- Function: Offers some benefits of both, providing stability while allowing for limited movement.
4)Morse Taper Center:
- Description: A type of taper used to lock the center into the tailstock or spindle.
- Function: Commonly used for both dead and live centers, depending on the application.
5)Ball Bearing Center:
- Description: A live center specifically designed with ball bearings.
- Function: Enhances rotational performance and reduces wear over time.
These rotary centers are crucial for achieving precision in various machining processes, including turning, milling, and grinding. Each type has its specific applications and advantages depending on the machining requirements.
