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).
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.
The tailstocks functions just as the manual tailstock but is pneumatic actuated and the pneumatic tailstock employ a replaceable morse taper.
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.
To align the tailstock on a lathe, follow these steps:
Check the Bed Level: Ensure the lathe bed is level and free of distortion, as this affects alignment.
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.
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.
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.
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.
Lock and Test: After alignment, lock the tailstock in place and perform a test cut to verify accuracy.
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.
