• 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 the jaw and scroll gear are partially engaged, clamping force is reduced. • Chuck Speed Rating: Exceeding the maximum rated speed indicated on the chuck, or using excessive spindle speeds with an unbalanced workpiece, can cause the workpiece to be thrown from the chuck causing a severe impact injury or even death. Always use the appropriate spindle speed for the job. • 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 nearby components. Before starting the spindle, make sure the workpiece and the chuck jaws have adequate clearance by rotating the spindle through its entire range of motion by hand. -2 Mfg. Since 3/10 I NS T R UCT IONS Model SB1314 Care & Maintenance Always disconnect machine from power before performing maintenance or serious personal injury may result. ! For optimum performance from your chuck, follow the maintenance schedule below, and never hammer on the chuck, jaws, or a workpiece clamped in the chuck. Never subject the chuck to abrasives, flame, or water. Daily: • Check/correct loose mounting bolts. • Use a vacuum, rag, or brush to clean the chuck after use. Never use air pressure to clean chips away from a chuck. • Wipe the chuck down with a thin coat of way oil to prevent surface rust. • Grease the chuck fitting with one to two pumps of NLGI #2 grease. If the chuck ever becomes stiff to operate, it may have been contaminated with metal chips or abrasives from neglect or poor service practices. The chuck must be dissembled, cleaned, and re- lubricated. To disassemble the chuck for a full cleaning and lubrication service: 1. DISCONNECT LATHE FROM POWER! 2. Mark the chuck and the mounting plate where they mate to ensure that when reassembled both halves line up. Next, unbolt the chuck and separate both halves. 3. Insert and rotate the chuck key counterclockwise until the scroll-gear has released all three jaws from the chuck. 4. Using a 4mm and 6mm hex wrench, a #1 standard screwdriver, and a ratchet with a 7mm socket, start at #1 and disassemble the chuck in the sequence shown in Figure 2. 2 3 6 4 5 1 Figure 2. Chuck sequence of disassembly. 7 Note: Each jaw is marked 1, 2, or 3 to correspond to its marked slot in the chuck 5. Using mineral spirits, clean and dry all components. Inspect all bores, teeth, pins, and mating surfaces for wear, burrs, galling, rust, or cracks. 6. Without changing the dimension of any part, use a wire brush, emery cloth, or dressing stones, to remove all rust, burrs, and any high spots caused by galling. 7. Coat all parts with any automotive NLGI #2 grease, and carefully reassemble the chuck in the reverse order shown in Figure 2. 8. Rotate the chuck key clockwise until you see the tip of the scroll-gear lead thread just begin to enter jaw guide #1. 9. Insert jaw #1 into jaw guide #1, and hold the jaw against the scroll-gear. 10. Rotate the chuck key clockwise one turn to engage the tip of the scroll-gear lead thread into the jaw. Pull the jaw; it should be locked into the jaw guide. 11. Install the other jaws in the same manner, and install a new grease fitting if ball or nipple leak grease. 12. Line up the timing mark on the chuck and the mounting plate, and fasten both halves by tightening and torquing the fasteners as outlined in Step 11 in Installation. -3 Copyright © March, 2010 By South Bend Lathe Co.
