OPERATION
Replacement of Chuck The head spindle holding fixture is cylindrical. Loose three set screws and nuts (A, Fig. 13 only two are shown) on the lathe chuck flange to remove the chuck. Position the new chuck and fix it using the same set screws and nuts.

Fig. 13
TOOL SET UP Clamp the turning tool into the tool holder. The tool must be clamped firmly. When turning, the tool has a tendency to bend under the cutting force generated during the chip formation. For best results, tool overhang should be kept to a minimum of 3/8″ or less. The cutting angle is correct when the cutting edge is in line with the center axis of the workpiece. The correct height of the tool can be achieved by comparing the tool point with the point of the center mounted in the tail stock. If necessary, use steel spacer shims under the tool to get the required height. (Fig. 14)

Cylindrical Turning (Fig. 21) In the straight turning operation, the tool feeds parallel to the axis of rotation of the workpiece. The feed can be either manual by turning the hand wheel on the lathe saddle or the top slide, or by activating the automatic feed. The cross feed for the depth of cut is achieved using the cross slide.
End turning ( Fig. 22 ) In the facing operation, the tool feeds perpendicular to the axis of rotation of the workpiece. The feed is made manually with the cross slide hand wheel. The cross feed for cut depth is made with the top slide or lathe saddle.
– 23 –

Turning: Slender shaft ( Fig. 23 ) For turning between centers, it is necessary to remove the chuck from the spindle. Fit the M. T. 3 center into the spindle nose and the M.T. 2 center into the tail stock. Mount the workpiece fitted with the driver dog between the centers. The driver is driven by a catch or face plate. Note: Always use a small amount of grease on the tail stock center to prevent center tip from overheating.
Taper Turning Using Tail stock Off-Set Adjust the deviation between the tailstock sleeve center and the spindle center to complete the taper turning. The angle depends on the length of the workpiece. To off-set the tail stock, loosen locking screw (A, Fig.24). Unscrew the set screw (B, Fig.24) on right end of the tailstock. Loosen the front adjusting screw( C, Fig.24 ) and take up the same amount by tightening the rear adjusting screw (D, Fig.24) until the desired taper has been reached. The desired cross- adjustment can be read off the scale. (E, Fig.24 ). First re-tighten the set screw (B, Fig,24) and then the two (front and rear) adjusting screw to lock the tail stock in position. Re-tighten the locking screw (A, Fig.24) of the tailstock. The workpiece must be held between two centers and driven by a face plate and driver dog.
– 24 –

After taper turning, the tailstock should be returned to its original position according to the zero position on the scale of tail stock. (E, Fig.24)
Fig.24 Thread Cutting Set the machine up to the desired thread pitch (according to the threading chart, Fig.20). Start the machine and engage the half nut. When the tool reaches the part, it will cut the initial threading pass. When the tool reaches the end of the cut, stop the machine by turning the motor off and at the same time back the tool out of the part so that it clears the thread. Do not disengage the half nut lever. Reverse the motor direction to allow the cutting tool to traverse back to the starting point. Repeat these steps until you have obtained the desired results. NOTES Example: Male Thread The workpiece diameter must have been turned to the diameter
of the desired thread. The workpiece requires a chamfer at the beginning of the thread
and
– 25 –

an undercut at the thread runs out. The speed must be as low as possible. The change gears
must have been installed according to the required pitch. The thread cutting tool must be exactly the sample shape
as the thread, must be absolutely rectangular and clamped so that it coincides exactly with the turning enter. The thread is produced in various cutting steps so that the cutting tool has to be turned out of the thread completely (with the cross slide) at the end of each cutting step. The tool is withdrawn with the lead screw nut engaged by inverting the change-over switch. Stop the machine and feed the thread cutting tool in low cut depths using the cross slide. Before each passage, place the top slide approximately 0.2 to 0.3mm to the left and right alternately in order to cut the thread free. This way, the thread cutting tools cut only one thread flank with each passage. Keep cutting the thread free until you have almost reached the full depth of thread.

Lathe Accessories
Three Jaw Universal Lathe Chuck Using this universal chuck round triangular square hexagonal octagonal and twelve,cornered stock may be clamped. (Fig.26) Note: new lathes have very tight fitting jaws. This is necessary to ensure accurate clamping and long service life- with repeated opening and closing the jaw adjusts automatically and their operation becomes progressively Smoother. Note: For the original 3, jaw chuck that was mounted on the lathe the factory has mounted the chuck in the best way to guarantee the holding accuracy with two “0” mark (A) Fig.26 showed on the chuck and chuck flange.
There are two types of jaws: Internal and external jaws. Please note that the number of jaws fits with the number inside the chuck’s groove. Do not mix them together. When you are going to mount them please mount them in ascending order 0, 1 , 3 when you are going to take them out be sure to
– 27 –

take them out in descending order 3,1,0 one by one- After you finish this procedure rotate the jaws to the smallest diameter and check that the three jaws are well-fitted. Four Jaw Independent Lathe Chuck This special chuck has four independently adjustable chuck jaws- These permit the holding of asymmetrical pieces and enable the accurate set,up of cylindrical pieces. (Fig.27)
DriII Chuck ( optional) Use the drill chuck to hold centering drills and twist drills in the tail stock(B) (Fig.28) Morse Taper Arbor (optional) An arbor is necessary for mounting the drill chuck in the tailstock. It has a No. 1 Morse taper. (C) Fig.28
– 28 –

Live Center (optional) The live center is mounted in ball bearings- Its use is highly recommended for turning at speeds in excess of 6.RPM. ( Fig.29)
Fig.29 Steady Rest The steady rest serves as a support for shafts on the free tail stock end. For many operations the tail stock can not be used as it obstructs the turning tool or drilling tool, and therefore, must be removed from the machine. The steady rest, which functions as an end support, ensures chatter- free operation. The steady rest is mounted on the bed ways and is secured from below with a locking plate. The grease requires continuous lubrication at the contact points to prevent premature wear. (Fig.30)
– 29 –

Setting the Steady Rest 1. Loosen three hex nuts. (A, Fig.31) 2. Loosen knurled screw (B, Fig.36) and open the sliding fingers. (C, Fig.31) until the steady rest can be moved with its finger around the workpiece. Secure the steady rest in position. 3 . Tighten knurled screws so that fingers are snug but not tight against the workpiece. Tighten three nuts (A, Fig.31). Lubricate the sliding points with machine oil. 4. When, after prolonged operation, the jaw show wear, the tips of the fingers may be filed or re-milled.
Follow Rest The following rest is mounted on the saddle and follows the movement of the turning tool. Only two support blocks are required. The place of the third support block is taken by the turning tool. The following rest is used for turning operations on long, slender workpieces. It prevents flexing of the workpiece under pressure from the turning tool. ( Fig.31 ) Set the support blocks snug to the workpiece but not overly tight. Lubricate the support blocks during operation to prevent premature wear.
– 30 –

ADJUSTMENTS After a period of time, wear in some of the moving components may need to be adjusted. Main spindle Bearings The main spindle bearings are adjusted at the factory. If end play becomes evident after considerable use, the bearings may be adjusted. Fasten the slotted nut (A, Fig.32) on the back of the spindle, The spindle should still revolve freely. Caution: excessive tightening or preloading will damage the bearings.
