2. ELECTRICAL CIRCUIT CONTROL 2-1 Electrical Wiring 1. The electrical control cabinet is located at the back side of headstock. Opening the cabinet cover and connect the power source wires to the terminals (R, S & T) The wires between the power source and the terminals must have over sectional area of 21.2mm for 230V (8.4 mm for 480V on 30HP...
2-3 Electrical Cautions 1. After wiring, check the rotation of the spindle of the spindle. Turn the main power switch “ON” and make sure the spindle is safe to turn. Then push jog button (T) momentarily. The correct direction of the spindle rotation is counter clockwise.
3. UNPACKING & MACHINE INSTALLATION 3-1 Unpacking & Lifting When the machine has 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 accessories. If there is, please contact our company or insurance company immediately in order to get the best solution or claim;...
3–2 Basic Foundation With the common usage of tungsten carbide cutting tools nowadays, heavy cutting and higher spindle speed are preferred. This may cause the vibration easily. In order to establish the best cutting condition it is necessary to build a sound & good floor foundation.
4. MAJOR CONSTRUCTION 4-1 Headstock 1. With high tensile durable cast iron material, which can withstand the higher work load, the internal gears are made of chrome molybdenum alloy steel, made after carburizing, quenching treatment, and precision grinding, and will reduce friction, noise and increase wear-resistant.
4-2 Spindle 1. Entire spindle is built by forging, cutting and precision grinding. 2. Spindle has a design as a three-point supporting system, the front-end of two ultra-precision taper roller bearings and back-end using a deep groove ball bearing can withstand heavy load, heavy cutting and enable precision turning purposes.
4-3 Spindle Speed Selection 1. Operation of the spindle speed, please refer to spindle speed table , Select the speed range “L”,”M” or “H”. Example: To select 680 rpm, shift the speed shifting lever to “H” position first, and then rotate the spindle speed shifting selection lever to the position “680”.
4-4 Carriage Slide 1. Carriage slide is the saddle-shaped casting on the lathe’s bed ways, the main structure are the saddle-shaped slide body, compound slide and the 4-way tool post. Main function of carriage slide is for mounting compound slide and tool holder, and then locking cutting tools for cross and longitudinal feed operation.
4-5 Tailstock 1. The main structure of the tailstock: the tailstock body, tailstock base plate, the tailstock sleeve, and speed control box. The tailstock sleeve and spindle are in the same level center position, also support the longitudinal movement on the bed and the spindle support the work material, cutting and drilling of two ends.
4-6 Apron The main function of the apron is moving backward and forward, the feed slide auto-feeding and thread cutting auto-feeding; the feed device are: thread indicator, the half nut control lever, auto-feeding lever ,tappet, longitudinal feeding hand wheel. 2. Apron with two auto feeding direction, cross-feed and longitudinal feed, according to the instructions of the nameplates first select operation required (pull - turn or push -turn knob) , then operate the automatically feed lever down to engage the feed.

turn off the lubrication, please turn clockwise to the end. Turn counterclockwise to start lubrication supply. Lubrication has 3 phases, from minimum to maximum only works on the process of apron moving. 5. There is a control panel at the right hand side of the apron. Each button on the control panel is “A”...
4-7 Gear Box 1. Transmission of Gearbox is from Headstock’s forward & reverses mechanism to idle-gears change up mechanism. And then via two 2 steps and one 3 steps speed change mechanism within gear box to a 9 steps speed change mechanism. Finally transfer through feeding change mechanism to lead crew and feed rod.
4-8 Thread Chasing Dial Dial indicates the engagement of the screw thread, in accordance to the attached thread cutting chart in which thread pitches can be found, location of these worm gears and engagement position of the lead screw, the dial indicator with the number of the leadscrew rotates.

6. Cutting thread is 1.1,2.75,5.5 of table data, use worm gear 11T can be aligned with a single mark, repeat the original single-point cutting until done only once. 7. Cutting thread of 1.3,3.25 table data, use the worm gear 13T can be aligned with single mark, repeat the original single-point cutting until done only once.
4-9 Steady Rest The function for steady rest is to support centering a long and flexible work piece. Please tighten clamp to a proper position, loosen set screw A, and rotate handwheels on the 3 quills to required position. Then after tighten set screw A, please lubricate periodically when using roller type tips.
4-10 Brake System Please press Emergency button, the power supply will cut off immediately and motor pulley will stop running. We offer foot pedal for brake with models within 3 meters between centers, models above 3 meters we do not offer. After stepping on the foot pedal, the power will cut off immediately and brake lining and motor pulley will stop running.
5. LUBRICATION 5-1 Headstock Lubrication Headstock lubrication is a splash injection combination system. Oil grooves are machined around the headstock to provide lubricant flowing from oil grooves to spindle, then the oil will reach down to the bottom of the headstock. To add oil, please take off the oil plug on the top of the headstock cover, and fill the oil to the centerline of oil sight glass.

6. MAINTENANCE & ADJUSTMENT Please refer to this chapter for machine’s problem, solution and maintenance to obtain the best function and prolong service life of the lathe. 6-1 Headstock 1. To avoid the headstock cover oil leaking: Once the headstock cover is opened, please use rags to clean the connecting surface, apply some grease sealant, and then user can close the cover and tighten the socket screws.
6-2 Apron & Saddle 1. Apron lubrication location: On the right top side of the saddle, the oil inlet plug marked “OIL” is the oil inlet hole. 2. Apron drain hole is located on the bottom cover of the apron. 3.
6-4 Belt Tension Adjustment After long period of usage, the belts will stretch and require tension adjustment. 1. Please take off the cover on the left rear side of the lathe. ○ 2. Loosen adjusting nut A and lower down the motor locating plate to suitable height until the desired belt tension is achieved.
The foot brake is connected with a micro switch. It should have 0 to 1mm end play between the brake arm and the switch’s roller head. The correct brake action should cut off the electricity first, and then brake to avoid the brake belt being worn out.
