2 – 3 Basic Foundation With the common usage of tungsten carbide cutting tools, nowadays, heavy cutting and quicker spindle speed are desired. This combination may cause vibration easily. In order to ascertain the best cutting condition, it is necessary to build a sound & good floor f o u n d a t i o n .
2 – 5 Level Adjustment Once the J-hook bolt and concrete are completely dried and fixed, it is time to adjust the level of the bedways. Two machinist’s levels (accuracy 0.02mm/1000mm) should be placed on the cross slide of the machine. Adjust the bolt for longitudinal direction of bed level.
3. ELECTRICAL CIRCUIT CONTROL 3-1 Electrical Wiring The electrical control box can be found by opening its cover at the back side of bed. Connect the power source wires to the connecting points (R.S.T) wire-grade power source and the connecting points must more than cross sectional area of (5.5...

4-2 Transmission & Stop of Spindle After the procedure described previously in this manual has been done, it is time to test run the machine. Position the spindle speed H/L shifting lever #2 to “L”, the spindle speed shifting selection lever #3 to the very left side, and forward/reverse shifting lever #4 to “N”...
For safety and protecting the gears from damage, only change speeds when the motor is completely stopped. If the gears are not easily engaged, press jog button momentarily and move the speed shifting levers to change the speeds. Caution: Do not shift gears while spindle is still turning. Be certain gears are properly engaged before starting.
4-5 The Importance and Method of Spindle Balancing Adjustment A lathe without spindle-balancing adjustment will cause finish to be chattered. As a result, this will influence the cutting accuracy of work piece and results in poor roundness-accuracy and have a chattered finish. It is necessary to pay attention to the spindle vibration from time to time in order to have the best cutting condition of the lathe.
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 item 1-1) to the right side, the spindle will rotate forward; to the left side it will reverse;...
○ ○ ○ ○ ○ Figure 4-8 4-9 Automatic Feeding Operation (1) Position the thread/reverse shifting lever (#4 of item 1-1) for obtaining the required feeding position. (2) Shift the thread/feed selection lever (#5 of item 1-1), thread/feed selection lever (#6 of item 1-1), 10-step feed selection lever to select the appropriate feeding rate.
(1) Rotate the adjustable trip dog (#12 of item 1-1) to the required setting position and make the top section of the adjustable trip dog face outward. Try test run the procedure and adjust the position of the adjustable trip dog if premium accuracy is required. (2) Secondly, rotate the 4-position automatic feed stop selection rod, move the second adjustable trip dog to the position by hand and fix the adjustable trip dog according to the procedure above.
5. Threading 5-1 Leadscrew drive Move the forward/reverse lever (#4 of item 1-1) to the right will cause the leadscrew to rotate backward, moving the lever to the left the leadscrew will rotate forward, and when lever is in neutral, the leadscrew will not turn. 5-2 Threading 1.

Example 2: For cutting pitches 1.75, 3.5, 7.0, please also use the same 14T worm gear and 2&7 division dial. But the dial numbers at which the leadscrew may be engaged is on 2; number 1 and 2. Half nuts Gear Dial Pitch...
6. LUBRICATION 6-1 Headstock Lubrication Headstock lubrication is splash injection type. Oil grooves are equipped around the headstock to provide lubricant flowing from oil grooves to spindle, and then finally reach the bottom of the headstock. To add oil, please take off the oil plug on the top of the headstock’s cover; fill the oil to the centerline of oil sight glass.
7. MAINTENANCE & ADJUSTMENT Please refer to following items for machine problems and its solution. And also ask users to maintain the lathe the best way, thus prolonging the service life of it. 7-1 Headstock 1. To avoid the headstock cover oil leaking: Once the headstock cover is opened, please use cloth to clean the matching surfaces and apply some grease, then you can close the cover and tighten the screws again.
7-2 Apron & Saddle 1. Apron lubrication location: On the right top side of the saddle, the oil inlet cap marked “OIL” is the oil inlet for apron. ○ 2. Apron drain hole located on the bottom cover of the apron as shown on the right side figure.
7-3 Gear Box 1. Lubrication location: Below the top cover of the gear box, take off the top cover to find the oil cap marked “OIL”, unscrew the cap to see the oil inlet hole. (show on ○ 2. Drain hole: On the left bottom side ○...
7-5 Belt Tension Adjustment After using the lathe for a long time, the belts will stretch and require tension adjustment. 1. Facing the back side of the lathe, please remove the cover on the lower right side of the lathe. 2.
7-7 Brake & Micro Switch Adjustment The foot brake is connected with a micro switch. It should have 0- 1mm end play between the brake arm and lever head of the micro switch. The correct brake action should cut off the electricity first, and then stop stepping on the brake to avoid the brake belt being worn out.
