M1109 Combo Lathe/Mill

Chuck and Faceplate

Mounting

The three-jaw scroll chuck has hardened steel jaws that self-center the workpiece within 0.002"-0.003". An extra set of jaws is included for machining larger workpieces.

The four-jaw chuck also has hardened steel jaws but are adjusted independently to hold an off-center workpiece. Each jaw can be removed from the chuck body and reversed for special clamping applications.

The cast-iron faceplate has slots for T-bolts that hold clamping fixtures. This face plate and aftermarket clamp- ing hardware will hold non-cylindrical parts such as cast- ings for many types of turning operations.

Both chucks and the faceplate are removed and installed the same way.

To remove and install the chuck or face plate, do these steps:

1.DISCONNECT POWER TO THE LATHE/MILL!

2.Lay a chuck cradle or protective layer of plywood over the bedways to prevent your fingers from being pinched and to protect the precision-ground surfaces (see Figure 15).

3. Use a 14mm wrench and loosen the three hex bolts that secure the chuck to the spindle Figure 16.

4. Support the chuck, and while anticipating the heavy weight of the chuck, remove the three hex bolts and then the chuck.

5. Clean the mating surfaces of the spindle and the new chuck or faceplate with a clean oiled rag.

6. Position the other chuck or faceplate on the spindle flange making sure it is fully seated, and tighten the hex bolts in several alternating sequences.

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.
