Lathe Chuck

The Model G4015Z Lathe/Mill comes equipped with a 4'' 3-jaw chuck (already installed).

The 3-jaw chuck is a scroll-type chuck, meaning that all three jaws move in unison when adjust- ments are made. Most 4-jaw chucks, on the other hand, feature jaws which are adjusted indepen- dently. A 4-jaw chuck can be used to hold square or rectangular stock.

The 3 jaws, on a 3 Jaw Chuck, open and close using the chuck key provided. Please refer to Figure 6. Rotating the key clockwise closes the jaws.

Grizzly offers 4-jaw chucks. Please note that a 5" adapter plate has been provided for mounting a 4-jaw chuck. Please see Grizzly’s current catalog for ordering information on 4-jaw chucks.

To use this mounting plate:

1.Fasten the plate to the 4-jaw chuck using the screws provided with the chuck.

2.Fasten the plate to the spindle plate using the 3 screws that were removed from the 3- jaw chuck.

DO NOT mount chucks measuring larger than 5" in diameter on this spindle.

Some 4-jaw chucks may not readily mount to the back plate provided. It may be necessary to drill new mounting holes and/or resurface and shoul- der the plate so the chuck may be mounted accu- rately and safely. Should you have questions regarding this, please consult your local technical school, trained expert or other trade resources.
