7 2. UNPACKING & MACHINE INSTALLATION 2- Unpacking When the machine is arrived, first, check if the wooden case is damaged or not, secondly, open the case and inspect the machine for any damage or short supply of parts. If so, please contact our company or insurance company immediately in order to get the best solution or refund; otherwise our company or the insurance company will not be in the position to compensate for the damage. 2-2 Lifting Please refer to figure 2-2 for machine unloading from the truck & moving: The steps of lifting the lathes are: () Clamp the bedways with a special made hanger, which consists of a clamp andan iron chain. (2) Raise the lathe a little bit with crane, then check if the lathe is balanced. If not, move apron and cross slide back or forth to make the machine is balanced. (3) While the machine arrives at the location, put down the machine slowly to avoid any inaccuracy of the machine caused by bumps or crash. (4) For adjusting the electrical cabinet, the machine should be located allowing sufficient area, min. over 600mm from wall at back and tailstock end. 6 Fig. 2-2

8 2 3 Basic Foundation With the common usage of tungsten carbide cutting tools nowadays, heavy cutting and quicker spindle speed are therefore reinforced. This may cause the vibration easily. In order to ascertain the best cutting condition it is necessary to build a sound & good floor basis. (Please refer to figure 2-3 for basic structure.) 2 4 Cleaning The machine is protected with a special anti-rust agent before delivery. Before operating the machine, clean all parts, especially the slideways, leadscrew, rack and all bright surfaces with soft brush/cloth soaked with cleaning solvent or kerosene. Do NOT use gasoline or cellulose solvent to avoid dangers or fire or explosion. After removing the anti-agent, keep the machine properly lubricated. Then turn the moving mechanism like tool post, tailstock by hand back & forth within their moving areas. 7

9 2 5 Level Adjustment Once the set screw and concrete are completely dried and fixed. It is time to adjust the level of the bedway. A machinist s level (accuracy 0.02mm/000mm) should be placed on the slide- ways of bed. Adjust the set screw for longitudinal direction of bed level. For transverse direction of bed level, tight the nuts until the accuracy is within 0.04mm/000mm. Then check again. If the deviation is resulted from the nuts, it is necessary to make another adjustment. (See Fig 2-5) Fig 2-5 8

10 3. ELECTRICAL CIRCUIT CONTROL 3- Electrical Wiring The electrical control box can be found by opening its cover at the back side of bed. Connect the power source wire with the connecting points (R.S.T) The wire between the power source and the connecting points must be over sectional area 8mm 2 (5.5 mm 2 for 480 or 9 series). The main switch between machine and power source also should be equipped with safety fuse. Besides, the machine must have a earth wire. Fig Electrical Equipment. The electrical control box is also equipped with overload circuit breaker and electric magnetic contactor to protect motor from burning out by overload. 2. The main switch is connected with micro switch. 3. The foot brake is connected with micro switch. Stepping the footbrake is quicker to stop the lathe than turning off the switch. The spindle can only revolute again by re-operating the spindle operation control lever after using the foot brake. 4. The spindle will rotate continuously as long as the intermittent switch on the top of the electrical panel is pressed. 3-3 Electrical Cautions After wiring, check the rotation of the spindle of the spindle. Turn the main switch ON and make sure the safety of spindle. Then push intermittent button (T) momentarily. The correction direction of the spindle rotation is counter clockwise. (looking from tailstock for a downward movement of the spindle operation control lever.) Wrong direction of rotation can be rectified by interchanging any two of the three phase lines (R.S.T.) in the power source. 9

17 4-5 The Importance and Methods of Spindle Leveling Adjustment. A lathe without proper leveling adjustment is likely to chatter. As a consequence, this will influence the cutting accuracy of work piece and result in poor roundness accuracy and finish. It is necessary to pay attention to the spindle leveling from time to time in order to have the best cutting condition of the lathe. Belt, 3-jaw chuck and the accumulative tolerances of parts on headstock, all such factors, can make the lathe chatter. To get rid of those problems, our lathe is especially designed to be equipped with leveling blocks mounted on the locking nut at the rear side of the spindle. The leveling blocks can be properly adjusted according to different condition. Please refer to following description & figure for proper adjustment. 2. Firstly, set up the spindle speed at 350 rpm. Put the palm on left hand of the headstock cover and press the switch by left hand. Then switch on the lathe to make the spindle turn. Move the leveling block A & C left or right by hand feeling until obtain the best leveling position. Then also move the leveling block B left or right till the best position with same way. Adjust repeatedly till your hand feels no chattering. Afterwards, change the spindle speed to 2000rpm or 880rpm and check the leveling in the same way as we did at 350rpm. Finally, for the leveling block set screw a, a, b.b. c.c. securely. 6 Fig.4-5

18 4-6 Transmission & Stop of Gear Box Open the end cover to find the gear train transmitting from headstock to gear box, position the forward/reverse shifting lever ( 4 of figure -) to right side, the spindle will rotate forward; to right; reverse; to Neutral, stop. Do not change the gears while turning. 4-7 Gear Box Operation. Threading: With the special design, there is no need to re-arrange the back gears for threading. Please refer to the threading & feeding table and handle the thread/feed selection lever ( 5 of figure -), thread, feed shifting lever ( 6 of figure -) and 0-step feed selection dial ( 7 of figure -) accordingly. 2. Auto feeding Also select the appropriate auto feeding rate by positioning the thread, feed selection lever ( 5 of figure -), thread, feed shifting lever ( 6 of figure -) and 0-step feed selection dial ( 7 of figure -) as indicated on the threading and feeding table. 4-8 Manual Operation First, position both the halt nut engage lever 8, and forward and reverse shifting lever ( 4 of figure -) to N position to operate the apron handwheel 3 cross slide handle 4, and compound rest handle 32 easily. It feeds 7mm or 20mm (according to requirement) per revolution of apron handwheel. The dials on cross slide and compound rest is graduated 0.02mm per calibration, and feeds 5mm per revolution. The tool post can be rotated clockwise after loosing the tool post clamping lever ( 36 of figure -). Then position and tighten the clamping lever. For fixing the apron, just handle the saddle clamping lever 20. For cross slide and compound rest, screw tightly the set screws beside the taper pin Fig. 4-8

(2) Shift the thread, feed selection lever ( 5 of figure -), thread, feed selection lever ( 6 of figure -), 0-step feed selection lever to select the appropriate feeding rate. (3) For threading, push the half nut engaged lever ( 8 of figure -) downward till fully engaged. (4) For cross feeding, pull the feed axis selector ( 9 of figure -) till full engaged. (5) For longitudinal feeding, push the feed axis selector downward. 4-0 Automatic Feeding Stop Operation The apron is equipped with automatic stop device. Tighten the screw on the top of the adjustable trip dog 2, and then fix it to the required position. Be careful that the top tip of the adjustable trip dog can be set onto the required position for forward and backward feeding. To avoid danger or damage to work piece, always have a test before starting. 4-4-position Automatic Feeding Stop Operation 8 Fig.4-0 To process certain length or step type of work piece, can use the 4-position Automatic feeding stop for length set cutting. () Rotate the adjustable trip dog ( 2 of figure -) to the required setting position and make the top tip of the adjustable trip dog face outward. Try to test the auto feeding and adjust the front and back position of the adjustable trip dog if required, in order to ascertain the position setting accuracy. (2) Secondly, operate the 4-position automatic feed stop selection lever to the second adjustable trip dog by hand and fix the adjustable trip dog according to above procedure. (3) Same procedure for the third and fourth adjustable trip dog. (4) While the apron is auto-feeding, only the top tip of adjustable trip dog, which faces outward can touch the trip plunger ( 5 of figure -). After stopping the auto feeding of apron, the other three adjustable trip dog can pass freely without any function. 2

20 4-2 Tailstock Operation () The tailstock handwheel dial is divided 0.02mm per graduation. The tailstock moves forward 5mm per clockwise revolution of handwheel. When revoluting clockwise, the quill will retract and, to the last, the center will release automatically. (2) Push the tailstock quill locking lever 30 forward to fix the tailstock quill. For fixing the tailstock onto the bedway, push tailstock body clamping lever 29 forward. (3) Adjust the centerline of the tailstock by loosing the tailstock set-over adjusting screw 26 on the side firstly, then adjust the screw on the other side. After adjustment, tighten the screw on both sides Fig.4-2 9

21 4-3 Rapid Traverse Operation (Optional device). When using rapid traverse, please keep 5 and 6 off. 2. To have safer operation, clutch must be off. 3. To make clutch come off, pull the hand wheel outward. Thus hand wheel does not rotate in high speed feeding, and does not injure the operator. 4. If it is necessary to feed by hand wheel, push the hand wheel inward. Meanwhile, turn the hand wheel counterclockwise to make the clutch engaged. 5. For rapid traverse toward right and left, buttons 3 and 4 are required. 6. Apron moves leftwards when button 3 is pressed, and stops when button 3 is released.

29 6. LUBRICATION 6- Headstock Lubrication Headstock lubrication is splash injection type. Oil grooves are equipped around the headstock to provide lubricant flowing from oil grooves to spindle, then finally reach the bottom of the headstock. To add oil, take off the oil plug on the top of the headstock cover, fill to the centerline of oil sight glass. Oil drain hole is located on the right bottom side of the headstock. Before operating the lathe, be sure the headstock is filled with oil. If not, add Shell Tellus #32. Exchange oil after one month use for the first time. Thereafter every three months. 6-2 Gear Box & Apron Lubrication. Gear box is reservoir oil bath type. To ensure the long service life of gear box and bedways, exchange the oil of gear box every six months. 2. Apron is also reservoir oil bath type. Add the oil as soon as the oil is lower than the center line of the oil sight glass. 6-3 Lubrication Charts No. Location Methods Headstock 2 Gear Box 3 Apron Loosen the oil input hole screw on the left top side of the headstock cover Open the top cover and loosen the oil input hole screw.

31 7. MAINTENANCE & ADJUSTMENT Please refer to following items for machine problem solution and maintenance for obtaining the best function and the long service life of the lathe. 7- Headstock. To avoid the headstock cover oil leaking: Once the headstock cover is opened, use cloth to clean the connecting surface and apply some grease, then can close the cover and tighten the set screw. 2. To avoid the returning oil route being blocked: There are two reasons which cause the oil leaking from headstock front cover; one is over oiled; the other is that the returning oil route is blocked. It should take off the headstock cover. Then blow air to the small hole, which is on the top of the front bearing, by air gun several times. And rotate the spindle at the same time to clean up the blocked returning oil route. 3. Spindle bearing adjustment: The front and middle bearings of the spindle is precision taper roller type. It requires to adjust the bearings to have suitable preload for maintaining the high accuracy and the best rotating functions. After long use the locking nut G may be loose a little bit and result in uneven cutting surface. For adjustment, loosen the setscrew by hexagon wrench. Then tighten the locking nut G to obtain the suitable preload. Do not over-tighten as over-preload will make the bearings hot, damage the rotating surface of the bearings and lower down the bearing motion functions. After adjustment, be sure to tighten the locking screw completely. G Fig.7-30

32 7-2 Apron & Saddle. Apron lubrication location: on the right top side of the saddle base, the oil inlet plug marked OIL is the oil inlet hole. 2. Apron drain hole located on the bottom cover of the apron as shown on the right side figure, the drain plug marked A (also see the chart on the front A bottom side of the apron). 3. Oil brand and oil exchange time: Use Shell Tellus T-68 and exchange the oil half a year. 4. To adjust the half nut engaged lever: After long use, the lever may be loosened and needed to be adjusted. First, take off the thread dial indicator and find the 4 gib strip adjusting screws. Second, while pressing the lever, also adjust the 4 gib strip adjusting screws until they are properly tightened. Afterwards, replace the thread dial indicator. 5. To clear up and repair the manual pump being blocked or small oil flow: If no oil oozes out after pushing the manual pump several times, the pump is blocked. Take off the 4 setscrews of the pump body and loosen the plug lever to dismantle the set nut. Use air gun to clean up the inside of the blocked pump. If the oil flow is too small, it must be the O-ring worn out, replace another new O-ring and assemble back the dismantled parts accordingly. 6. Adjustment for the longitudinal & cross auto feeding overload: The cone clutch on the center of the apron is an overload device. The safety overload weight limitation is 2 kgs. Overload weight can be adjusted by means of the Hexagon screw on the center of the apron; tighten clockwise, the overload will increase; tighten anticlockwise, the overload will then decrease. When auto-feeding, press the handwheel by hand, it should automatically slip out if the overload is over 2 kgs. If not, adjust again. D Fig.7-2 3

33 7-3 Gear Box. Lubrication location: Below the top cover of the apron, take off the top cover to find the oil plug marked OIL, the oil inlet hole. 2. Drain hole: On the left bottom side of the 0-step feed selection dial. The screw with hexagon nut is the oil drain hole as arrow A B shown on figure Oil brand and oil exchange time: Use Shell Tellus Omala 50 and B exchange the oil half a year. Fig Tailstock Center Line Adjustment First, unclamp the tailstock body clamping lever, and then loosen the 2 hexagon head screw on both right and left sides which lock the tailstock body and base together. Determine the direction and amount of the misalignment for adjustment by positioning a test bar between two dead centers. Slacken the rear location screw (say one half turn). Then alternatively slacken one set-over screw and tighten the other until the required setting is achieved, (correct alignment). Carefully retighten the rear location screw and the set over screw which was slackened before and recheck alignment. Retighten the two hexagon head screw carefully and re-clamp the tailstock (figure 7-4) If still can not operate the handwheel easily after the tailstock quill is fixed, it is caused by the reason that the clamping block can not be loosened. To solve it, just push the tailstock body clamping lever forward one time for recovering. A Fig. 7-4 B 32

34 7-5 Belt Tension Adjustment After long use, the belt will stretch and require periodic tension adjustment.. Take off the cover on the left back side of the lathe. 2. Loosen adjusting nut A and lower down the suitable height until the desired belt tension is achieved. 3. After adjustment, be sure to tighten the adjusting nut securely. 7-6 Brake Belt Adjustment Fig 7-5 If the brake belt is worn out and cause the brake band tool loosen, it is time to adjust the nut H of the brake band. Remove the side rear cover, loosen the nuts on the top firstly and tighten the nuts on the bottom to the appropriate height. Then tighten the nuts on the top to complete the adjustment. After adjustment, replace the side rear cover. H A Fig

35 7-7 Brake & Micro Switch Adjustment The foot brake is connected with the micro switch. It should have 0-mm end play between the brake arm and the touching, head of the micro switch. The correct brake action should cut off the electricity first, then brake to avoid the brake belt being worn out. After stepping the foot brake, needs to re-operate the spindle operation control lever to make the spindle revolute again. 7-8 Leadscrew Backlash Adjustment Fig. 7-7 If multiple cutting is happened while threading, it is caused by the leadscrew backlash. To adjust the leadscrew half nut properly, open the plastic cover of the leadscrew bracket and loosen nut A. Then tighten the left side nut B until there is no backlash. (For testing, press down the half nut by hand, turn the apron handwheel forward and reverse and grasp the connecting section of the gear box and leadscrew till no backlash happened.) Afterwards, replace the nut A to the leadscrew bracket. 7-9 Cutting Coolant Repair A B Fig. 7-8 If there is no coolant coming out after the pump switch is turned on, check the pump motor is working or not. If yes, check and see if the coolant in the tank is over the pump or not, If not, add the coolant, then turn on the switch, If there is still no coolant, the pump must be blocked. Take off the pump to clean up or repair. 34
