Tailstocks

The tailstocks uses a manual,pneumatic or hydraulic brake system for utilization with their rotary tables and indexing tables,to ensure the workpiece or fixture remains rigid during the machining process.

Tailstocks is a crucial component of a lathe machine that supports the end of a workpiece while it is being turned. It is typically positioned opposite the headstock (where the spindle is located). The tailstock can be adjusted along the bed of the lathe to accommodate workpieces of different lengths. It provides support for tools like a live center, dead center, or drills, and it helps maintain the alignment and stability of the workpiece during machining operations. YUNWU® offers four types of (manual tailstocks,hydraulic tailstocks,pneumatic tailstocks ,rotary tailstocks).

Manual Tailstock

Manual Tailstock

Manual Tailstock

The manual tailstock uses a Morse taper center to support long workpieces on the rotating worktable during the machining process. By turning the handle at the rear of the device, the center can be easily moved forward and backward.They are essential components that contribute to the precision and efficiency of machining operations, providing reliable support for your workpieces.

Pneumatic Tailstock

The tailstocks functions just as the manual tailstock but is pneumatic actuated and the pneumatic tailstock employ a replaceable morse taper.

  • Pneumatic Actuation: The tailstock is adjusted by compressed air, providing smooth and consistent motion. This can be controlled with a valve or pressure regulator for precise positioning.
  • Replaceable Morse Taper: As with the hydraulic version, the Morse taper in the pneumatic tailstock is replaceable. This means you can swap out the taper when it wears down or needs to be changed for different tooling setups.

    Hydraulic Tailstock

    The tailstocks functions just as the manual tailstock but is hydraulic actuated and the hydraulic tailstock employ a replaceable morse taper.


  • Hydraulic Actuation: Provides more precise and easier adjustment compared to manual tailstocks.
  • Replaceable Morse Taper: Offers flexibility and convenience for maintaining or changing tooling and centers.

  • Rotary Tailstock

    Rotary Tailstock

    The rotary tailstock support, typically positioned on one side of the machine, is designed to work in conjunction with a connection plate and the 4th axis rotary table on the opposite side. This configuration ensures stability and precision during machining processes. The rotary tailstock support can be equipped with either a pneumatic brake or a hydraulic brake, providing enhanced control and holding force, depending on the application requirements.

    How to Align Tailstock on Lathe

    To align the tailstock on a lathe, follow these steps:

    1. Check the Bed Level: Ensure the lathe bed is level and free of distortion, as this affects alignment.

    2. Install a Test Bar: Place a precision test bar (such as a mandrel or a dead center) in the headstock spindle, making sure it's mounted securely.

    3. Align the Tailstock: Move the tailstock along the bed, positioning it so that its center aligns with the headstock. You can check alignment using a dial indicator or a telescoping gauge.

    4. Adjust the Tailstock: If necessary, adjust the tailstock alignment using the adjusting screws or shims to bring the tailstock center in line with the headstock.

    5. Check for Parallelism: Once aligned, use a dial indicator to check if the tailstock is parallel to the headstock. Measure at both the front and rear of the bed to ensure uniform alignment.

    6. Lock and Test: After alignment, lock the tailstock in place and perform a test cut to verify accuracy.

    What is the purpose of the tailstock on a lathe

    The tailstock on a lathe provides support for the workpiece during machining, particularly for longer pieces that may bend or flex. It can hold tools like drills, reamers, or center drills, and it helps align and secure the workpiece for precision operations. The tailstock also allows for axial movement to accommodate different lengths of stock and can be adjusted to ensure proper alignment and support.

    Common types of tailstock centers

    Live Center: A rotating center that allows the workpiece to turn freely. It’s typically used for supporting long or cylindrical workpieces and reducing friction.

    Dead Center: A non-rotating center that doesn’t turn with the workpiece. It's used for precision work, where minimal movement or friction is desired.
