Scroll Chuck Clamping

This scroll-type chuck has an internal scroll-gear that moves all jaws in unison when adjusted with the chuck key. This chuck will hold cylindrical parts on-center with the axis of spindle rotation and can be rotated at high speeds if the workpiece is properly clamped and balanced.

Never mix jaw types or positions to accommodate an odd-shaped workpiece. The chuck will spin out of balance and

may throw the workpiece! Instead, use an independent jaw chuck or a faceplate.

4-Jaw Chuck

Refer to the Chuck Installation (see Page 33) and Chuck Removal (see Page 34) instructions to install or remove the 4-jaw chuck.

The 4-jaw chuck features independently adjustable hardened steel jaws for holding non- concentric or off-center workpieces. Each jaw can be independently removed from the chuck body and reversed for a wide range of work holding versatility.

Because of the dynamic forces involved in machining a non-concentric or off-center workpiece, always use a low spindle speed to reduce risk of the workpiece coming loose and being thrown from the lathe, which could cause death or serious personal injury.

Mounting Workpiece

1.DISCONNECT LATHE FROM POWER!

2.Place a chuck cradle or plywood on the bedway below the chuck to protect the bedway surfaces.

3.Use the chuck key to open each jaw so the workpiece will lay flat against the chuck face, jaw steps, or into the spindle opening.

4.With help from another person or a holding device, position the workpiece so it is centered in the chuck.
