Using the Four-Jaw Chuck

To install the four-jaw chuck, do these steps:

Refer to the Three-Jaw Direct Mount Scroll Chuck pro- cedures on Page 15 to mount the four-jaw chuck.

To load a workpiece in the four-jaw chuck, do these steps:

1.Using the chuck key, open each jaw so the workpiece will lay flat against the chuck face.

2.Support the workpiece.

3.Lock the tailstock and then turn the tailstock quill so the dead center makes contact or is close to the center point of your workpiece (see Figure 20).

4.Turn each jaw until it just makes contact with the workpiece.

5.In an opposing pattern, tighten each jaw in small increments. After you have adjusted the first jaw, continue tightening the opposing jaw. Check the dead center alignment frequently to make sure you have not wandered off your index point due to applying too much pressure to a single jaw.

6.After the workpiece is held in place, back the tailstock away and rotate the chuck by hand. The center point will move if the workpiece is out of center.

7.Make fine adjustments by slightly loosening one jaw and tightening the opposing jaw until the workpiece is precisely aligned. Use a dial indicator for fine tun- ing adjustments in alignment (see Figure 21).

8.Use a lower RPM when machining heavy eccentric workpieces.

Securely clamp your workpiece and remove the chuck key! Thrown objects from a lathe/mill can cause serious injury or death to the operator and to bystand- ers many feet away.

PINCH HAZARD! Protect your hands and precision ground bedways with plywood when removing lathe/mill chuck! The heavy weight of a fall- ing chuck can cause serious injury.
