7 6.0 Installation 1. Finish removing the wooden crate from around the lathe. 2. Unbolt the lathe from the shipping crate bottom. 3. Choose a location for the lathe that is dry, has good lighting, and has enough room to service the lathe on all four sides 4. Place two steel rods or pipes (of sufficient strength) into four holes (A, Fig. 2) of lathe stand. Sling the lathe with properly rated straps. Do not lift by spindle. With adequate lifting equipment, slowly raise the lathe off the shipping crate bottom. Make sure lathe is balanced before moving. 5. To avoid twisting the bed, the lathe's location must be absolutely flat and level. Check for a level condition using a machinist's precision level on the bedways both front to back and side to side. The leveling pads included in the tool box and the leveling screws in the lathe base will help you to reach a level condition. The lathe must be level to be accurate. 6. Clean all rust protected surfaces using a mild commercial solvent, kerosene or diesel fuel. Do not use paint thinner, gasoline, or lacquer thinner, as these can damage painted surfaces. Cover all cleaned surfaces with a light film of Mobil DTE Oil Heavy Medium. 7. Open the end gear door. Clean all components of the end gear assembly and coat all gears with Mobilith AW 1. Close the door. Figure Chuck preparation (three jaw) Read and understand all directions for chuck preparation. Failure to comply may cause serious injury and/or damage to the lathe! Note: Before removing the chuck from the spindle, place a way board across the bedways under the chuck 1. Support the chuck while turning three camlocks 1/4 turn counter-clockwise with the chuck key enclosed in the tool box. 2. Carefully remove the chuck from the spindle and place on an adequate work surface. 3. Inspect the camlock studs. Make sure they have not become cracked or broken during transit. Clean all parts thoroughly with solvent. Also clean the spindle and camlocks. Figure 3 7

11 10.0 General description Lathe bed The lathe bed (A, Fig. 11) is made of high grade cast iron. By combining high cheeks with strong cross ribs, a bed with low vibration and high rigidity is realized. Two precision ground vee slideways, reinforced by heat hardening and grinding, are an accurate guide for the carriage and headstock. The main drive motor is mounted in the stand below headstock. Headstock The headstock (B, Fig. 11) is cast from high grade, low vibration cast iron. It is bolted to the bed by four screws with two adjusting screws for alignment. In the head, the spindle is mounted on two precision taper roller bearings. The hollow spindle has Morse Taper #5 with a 1-1/2" bore. Carriage The carriage (A, Fig. 12) is made from high quality cast iron. The sliding parts are smooth ground. The cross slide is mounted on the carriage and moves on a dove tailed slide which can be adjusted for play by means of the gibs. The compound slide (B, Fig. 12), which is mounted on the cross slide (C, Fig. 12), can be rotated through 360. The top slide and the cross slide travel in a dovetail slide and have adjustable gibs. A four way tool post is fitted on the top slide. Four way tool post The four way toolpost (D, Fig. 12) is mounted on the top slide and allows a maximum of four tools to be mounted simultaneously. Remember to use a minimum of two clamping screws when installing a cutting tool. Apron The apron (E, Fig. 12) is mounted to the carriage. In the apron a half nut is fitted. The half nut gibs can be adjusted from the outside. The half nut is engaged by use of a lever. Quick travel of the apron is accomplished by means of a bed mounted rack and pinion, operated by a hand wheel on the front of the apron. Tailstock The tailstock (A, Fig. 13) slides on a v-way and can be locked at any location by a clamping lever. The tailstock has a heavy duty spindle with a Morse Taper #3. Leadscrew and feed Rrod The leadscrew (B, Fig. 13) and feed rod (C, Fig. 13) are mounted on the front of the machine bed. They are connected to the gearbox at the left for automatic feed and lead, and are supported by bushings on both ends. Both are equipped with brass shear pins. Figure 11 Figure 12 Figure 13 11

12 Gear box The gear box (D, Fig. 13) is made from high quality cast iron and is mounted to the left side of the machine bed. Steady rest The steady rest (E, Fig. 13) serves as a support for shafts on the free tailstock end. The steady rest is mounted on the bedway and secured from below with a bolt, nut and locking plate. The sliding fingers require continuous lubrication at the contact points with the workpiece to prevent premature wear. To set the steady rest: 1. Loosen three hex socket screws. 2. Loosen knurled screw and open sliding fingers until the steady rest can be moved with its fingers around the workpiece. Secure the steady rest in position. 3. Set the fingers snugly to the workpiece and secure by tightening three hex socket cap screws. Fingers should be snug but not overly tight. Lubricate sliding points with Mobil DTE Oil Heavy Medium. 4. After prolonged use, the fingers will show wear. Re-mill or file the tips of the fingers. Follow rest The traveling follow rest (F, Fig. 13) is mounted on the saddle and follows the movement of the turning tool. Only two fingers are required as the place of the third is taken by the turning tool. The follow rest is used for tuning operations on long, slender workpieces. It prevents flexing of the workpiece from the pressure of the cutting tool. The sliding fingers are set similar to the steady rest, free of play, but not binding. Always lubricate with Mobil DTE Oil Heavy Medium. Figure 13 (repeated) Controls 1. Control Panel - located on front of gearbox. A. Coolant On-Off Switch (A, Fig. 14) turns coolant pump on and off. B.

Tighten tailstock clamping bolt (underside of tailstock) 1/4 turn. Test for proper locking. Repeat as necessary Tailstock off-set Follow the procedure below to off-set the tailstock to cut shallow tapers: 1. Lock tailstock in position by raising locking handle (A, Fig. 24). 2. Alternately loosen and tighten two hex socket cap screws (B, Fig. 24). Figure Tailstock gibs Take up play in the tailstock by tightening two gib screws (C, Fig. 24) on either side of the tailstock base. Note: Do not over tighten. Excessive tightening will lead to premature wear of the gibs and mating parts 17

18 12.7 Headstock alignment The headstock has been aligned at the factory and should not require adjustment. However, if adjustment is deemed necessary, follow the procedure below to align the headstock: 1. Using a machinist's precision level on the bedways, make sure the lathe is level side to side and front to back. If the lathe is not level, correct to a level condition before proceeding. Re-test alignment if any leveling adjustments were made. 2. From steel bar stock of approximately two inches in diameter, cut a piece approximately eight inches long. 3. Place two inches of bar stock into chuck and tighten chuck. Do not use the tailstock or center to support the other end. 4. Set up and cut along five inches of bar stock. 5. Using a micrometer, measure the bar stock next to the chuck and at the end. The measurement should be the same. 6. If the measurements are not the same and adjustment is required, loosen hex socket cap screws (A, Fig. 25) which holds the headstock to the bed. Do not loosen completely; some drag should remain. 7. Adjust two screw nuts (B, Fig. 25) located on the endgear side of the headstock. Loosen one and tighten the other. Make another cut. Keep adjusting screw nuts after each cut until the bar stock measurements are the same. Tighten all headstock screws Removing gap section 1. To remove gap section, locate two nuts (A, Fig. 26) in the center of the gap section. 2. Using an open end wrench, tighten the two nuts. This will cause the taper pins to release. Remove the taper pins. 3. Remove six hex socket cap screws (B, Fig. 26) with a hex key wrench. 4. Gap section can now be removed. Figure 25 Figure Installing gap section 1. Clean the bottom and the ends of the gap section thoroughly. 2. Set gap section in place and align. 3. Remove nuts from the taper pins. 4. Slide taper pins in their respective holes and seat using a mallet. Install nuts on the taper pins finger tight. 5. Install six socket head cap screws and tighten securely. 18

19 12.10 Belt replacement and adjustment 1. Disconnect machine from the power source (unplug). 2. Open the end gear cover and lower cover on the headstock side. 3. Take tension off old belts by loosening motor mount hex nut (A, Fig. 27). 4. Remove belts. Install new belts onto pulleys. 5. Tension by tightening motor mount hex nut until 8 lbs. force causes approximately 3/4" deflection on belts. 6. Close end gear door, install cover and connect lathe to the power source Aligning tailstock to headstock Before proceeding, headstock should be aligned. See section labeled "Headstock Alignment". 1. Fit a 12" ground steel bar between centers of the headstock and tailstock (Fig. 28). 2. Fit a dial indicator to the compound slide and traverse the center line of the bar, using the carriage movement. 3. If tailstock adjustment is needed, alternately loosen and tighten front and rear hex socket cap screws (A, Fig. 29). Figure 27 Figure 28 Figure 29 19
