Accurately measure the inside of the back relief bore on the chuck. This dimension is critical and should be ± 0.001''. 4. Face the back plate to true it. Make passes across the face until its entire surface has been cut. 5. Turn a shoulder into the face 1.8'' deep and 0.001" to 0.002'' larger than the back relief bore diameter. Remember that this is a press fit. Chamfer the corner a small amount to prevent any burrs when installing. -1 6. Set the chuck on the back plate, aligning the shoulder with the relief bore. Use a transfer punch to mark the back plate. If a transfer punch is not available, a drill bit of the same size as the mounting holes in the chuck can be used. Lightly tap on the bit, rotate it 90° and tap it again. 7. Remove the chuck from the back plate and center punch the marks. Drill and tap the holes for M10-1.5 threads. 8. Remove the back plate from the lathe, and place it in to a freezer for 30 minutes, and place the chuck in an oven at 100° F. for the same amount of time. 9. Put on insulated leather gloves and place the chuck on the back plate. Line up the mounting holes and thread in the cap screws supplied. 10. Snug the first M10-1.5 cap screw, then alternate the cap screws across the chuck until you reach a final torque of 53.5 ft/lbs. Alternating the tightening process insures the chuck will be pressed on straight. This step should be repeated until the back plate fits snugly against the chuck. If the chuck fits loosely on the back plate, or is crooked on the shoulder, it will be necessary to recut the back plate face and shoulder again. If you are also installing the chuck by threading the M10-1.5 hex bolts into the chuck from the back side of the mounting plate, repeat Step 9 on these bolts, but torque them to 30 ft/lbs. Operation and Safety • Chuck Key Safety: A chuck key left in the chuck can become a dangerous projectile when the spindle is started. Always remove the chuck key after using it. Develop a habit of not taking your hand off of a chuck key unless it is away from the machine. • Disconnect Power: Disconnect the lathe from power before installing and removing the chuck or doing any maintenance or adjustments. Accidental lathe startup can cause severe injury or death. • Secure Clamping: A thrown workpiece may cause severe injury or even death. When swapping the chuck jaw positions, use a torque wrench to re-torque the M8-1.25 jaw mounting cap screws to 29 ft/lbs. When clamping a workpiece, maximum gripping force is attained at full jaw and scroll gear engagement. If jaw and scroll gear are partially engaged, clamping force is reduced. • Speed Rates: Operating the lathe where maximum chuck speed is exceeded, or at too high of a speed for an unbalanced workpiece, can cause the workpiece to be thrown from the chuck. Always use the appropriate feed and speed rates. A thrown workpiece may cause severe injury or even death. • Large Chucks: Large chucks are very heavy and difficult to grasp, which can lead to crushed fingers or hands if mishandled. Get assistance when installing or removing large chucks to reduce this risk. Protect your hands and the precision ground ways by using a chuck cradle or piece of plywood over the ways of the lathe when servicing chucks. • Safe Clearances: Often chuck jaws will protrude past the diameter of the chuck and can contact a coolant nozzle, tooling, tool post, or saddle. Before starting the spindle, make sure the workpiece and the chuck jaws have adequate clearance by rotating it through its entire range of ...
