    UNCRATING AND CLEAN-UP 1. Finish removing the wooden crate from around the lathe 2. Check all the accessories of the machine tool according to the packing list. 3. Unbolt the lathe from the shipping crate bottom. 4. Choose a location for the lathe that is dry, has good lighting and has enough room to be able to service the lathe on all four sides.

  • Page 8: General Description

    GENERAL DESCRIPTION Lathe Bed (Fig. 03) The lathe bed is made of high-grade iron. By combining high cheeks with strong cross ribs, a bed of low vibration and rigidity is produced. It integrates the headstock and drive unit, for attaching the carriage and leadscrew. The two precision-ground V - sideways, re-enforced by heat hardening and grinding, are the accurate guide for the carriage and tailstock.
  • Page 9 Apron (Fig. 07) The apron is mounted on the bed. It houses the half nut with an engaging lever for activating the automatic feed. The half nut gibs can be adjusted from the outside. A rack, mounted on the bed, and a pinion operated by handwheel on the carriage allow for quick travel of the apron.

  • Page 10: Controls

    CONTROLS 1. Change-over Switch (A, Fig. 11) After the machine is switched on, turn the switch to “F” position for counter-clockwise spindle rotation (forward). Turn the switch to “R” position for clockwise spindle rotation (reverse). “0” position is OFF and the spindle remains idle.
  • Page 11 9. Carriage Lock Turn hex socket cap screw (A, Fig.14) clockwise and tighten to lock. Turn counter-clockwise and loosen to unlock. Caution: carriage lock screw must be unlocked before engaging automatic feeds or damage to lathe may occur. 10. Longitudinal Traverse (B, Fig. 15) Rotate hand wheel clockwise to move the apron assembly toward the tailstock (right).

  • Page 12: Operation

    OPERATION Replacement of Chuck The head spindle holding fixture is cylindrical. Loosen three set screws and nuts (A, Fig.17, only two are shown) on the lathe chuck flange to remove the chuck. Position the new chuck and fix it using the same set screws and nuts.
  • Page 13 Manual Turning Apron travel, cross travel, and top slide handwheel can be operated for longitudinal or cross feeding. (Fig.21) Longitudinal Turning with Auto-Feed 1. Set the selector knob (A, Fig.22) to select the feed direction and feed speed. 2. Use the table (B, Fig.22) on the lathe for selecting the feed speed or the thread pitch.
  • Page 14 THREADING AND FEEDING TABLE FOR METRIC LATHE...
  • Page 15 Straight Turning (Fig. 25) In the straight turning operation, the tool feeds parallel to the axis of rotation of the workpiece. The feed can be either manual by turning the handwheel on the lathe saddle or the top slide, or by activating the automatic feed. The crossfeed for the depth of cut is achieved using the cross slide.
  • Page 16 Taper Turning by Setting the Top Slide By angling the top slide, tapers may be turned manually with the top slide. (Fig. 29) Rotate the top slide to the required angle. A graduated scale permits accurate adjustment of the top slide. The crossfeed is performed with the cross slide.

  • Page 17: Lathe Accessories

    LATHE ACCESSORIES Three Jaw Universal Lathe Chuck Using this universal chuck, round, triangular, square, hexagonal octagonal, and twelve-cornered stock may be clamped. (Fig.31) Note: new lathes have very tight fitting jaws. This is necessary to ensure accurate clamping and long service life.
  • Page 18 Steady Rest The steady rest serves as a support for shafts on the free tailstock end. For many operations the tailstock can not be used as it obstructs the turning tool or drilling tool, and therefore, must be removed from the machine. The steady rest, which function as an end support, ensures chatter-free operation.

  • Page 19: Adjustment

    ADJUSTMENT After a period time, wear in some of the moving components may need to be adjust Main Spindle Bearings The main spindle bearings are adjusted at the factory. If end play becomes evident after considerable use, the bearings may be adjusted. Loosen two hex socket cap screws (A, Fig.38) in the slotted nut (B, Fig.38) on the back of the spindle.

  • Page 20: Lubrication

    LUBRICATION CAUTION! Lathe must be serviced at all lubrication points and all reservoirs filled to operating level before the lathe is placed into service! Failure to comply may cause serious damage! NOTES: WfAHOMG Lubricate all slideways lightly before every use. Lubricate the change gears and the leadscrew slightly with a lithium-based grease.
  • Page 21 oil port (A, 6. Leadscrew Lubricate the oil port (A. FIG.46) with 20W machine oil once daily. 7. Tailstock Lubricate two oil ports (B. Fig.46) with 20W machine oil once daily.
