APPLICATION

This machi

ne is a small-scale universal engine lathe. It can perform various turning as well

as boring, drilling, grooving and other operations, it can also be used for turning metric threads

and English threads.

The machine is characterized by a simple construction, ah easy operation, large spindle hole

and small space occupation. It is used in the instrument industry and repairing workshops and is

suitable for metal manufacturing in single piece, small and medium batch production.

3. Choose a location for the lathe that ls dry, has good lighting, and has enough room to be able lo service the lathe on all four sides. The fixed dimension of the machine Is shown in Fig. _ _

4. Sling lathe as shown In tl'le hoisting ct,art Fig. 1 when it is transporting. Wilh adequate lifting equipment, slowly raise the lathe off the shipping crate bottom. Be sure that the suspension rope is through space between three rods and bed. Adjust the hoisting balance by sliding the saddle. Make sure lathe is balanced before moving.

5. To avoid twisting the bed. the lathe's location must be absolutely Oat and level. Check for a level condition I.Ising a machinist's precision level on the bed way both front to back and side to side

6 . Clean all surfaces off anti-rust oll using .a mild commerci.al solvent. kerosene or diesel fuel. Do not use paint thinner, gasoline. or lacquer thinner. These will damage painted surfaces. Cover all cleaned surfaces With a light film of 20# maohlne oil.

7. Remove the change gear cover. Clean all components of the change gear assembly and coat all gears with heavy, non-slinging grease Replace cover.

BREAK�NPROCEDURE

• During manufacturing and testing, th.is lathe has b.een operated at low spindle speed range for three hours.

• The machine is equipped with 2 V-belts between the motor pulley and the rear pulley. It is advisable to check the tension before starting the machine. The belts should be depressed about 1/2 inch or 12mm by normal finger pressure.

• To allow time -for the gears and bearings to break-in and run smoothly, do not run the lathe above 800 R.P.M for the first six hours of operation and use

ADJUSTMENTS

After a period of t ime, wear in some of the mo.ving components may need to be adjusted. • Saddle

1 Loosen four hex nuts round on the bottom rear of the cross slide and back off one full turn eaoh

2 Turn each of the four set screws with a hex wrench until a slight resistance Is felt Do not over lighten these screws

3. Move the carriage with the hand wheel and determine 1f the drag fs to your preference. Readjust the setting screws as to achieve the desired drag.

4 Hold the socket set screw firmly with a hex wrench and tighten the hex nut ta lock the setting screw in place.

5. Move the carriage again and adjust again if necessary. Note: over adjustment will cause excessive premature wear of the gibs.

• Cross Slide

If the cross slide is loo loose, follow procedure below to tighten. 1- Loosen the rear gib screw approximately one tum. 2 . Tighten the front gib screw a quarter turn. Turn lhe cross slide handwnee( to see if the

cross slide is still loose. If tt is still loose, tighten the front screw a btt more and try again. 3. When the ?ross slide Is properly adjusted, tighten the rear gib screw. Do not over tighten

This will cause premature wear on the gib and mating parts. • Compound Rest

Follow the same procedure as the cross slide adJustmeni to adjust the compound rest. • Tailstock

If the handle will not lock the tallstock, follow the procedure below 1. Lower the handle to unlocked position.

1 8 .

2. Slide the tailstock to an area that allows access to the underside of the tallstock. 3. Tighten tailstock clamping bolt 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 ta'ilstock in position by raising locking handle (20. Fig. 7). 2. Alternately IL and tighten front and rear hex socket cap screw (22, Fig. 7).

• Clearance of Cross Slidt! Adjustment

Adjust the cl,-arance of cross feed nu1s on the "!ddle as fo, .. v:1 1g: rotate the screw (1) until the slide moves\'> th a slight drag. (Flg. 15)

'--' • Chuck and Faceplate Mounting

The connection· bet.ween spindle and chuck or faceplate ls made by D -Cam Lock structure

'according to China National Standard GB5900.3-86 (similar to ISO 702/11-1975).
