3.0 TRANSMISSION SYSTEM
1. Main moving system
The four-grade speeds spining at the main
spindle of machine tool is realized by three
triangle belt cone pulleys, driven by triangle
belts, the speed changes is shown as Fig. 2.
Motor shaft
A: 1; 250 rpm.
A: 2; 500 rpm.
Bridge shaft
B: 1; 1000 rpm.
B: 2; 2000 rpm.

2. Feed moving system
The longitudinal feed motion of the machine tool is done by a gear at the spindle
end, through a gear change transmitted to the leading screw and towing the slider,
the threads of which is as table 1 on page 29.
4.0 INSTALLATION AND TEST RUN
1. After opening package box, check whether the accessories of machine tool is
complete, whether machine tool and electric apparatus circuits have any
damage, according to packing list.
2. Install the machine tool securely on a solid platform with two M8 screw bolts.
3. When the lathe is transitted, all movable parts must be fixed, so as to avoid
machine tilt and damage by parts slid and impact.
4. Clear the anti-rust grease surfaces with gasoline and kerosene, pour some
mechanical oil on surfaces of slideway, tailstock sleeve, leading screw and
other places for lubrication.
5. Turn the handwheels by hand, check whether the moving parts are blocked or
loosened and make appropriate adjustments.
6. Insert the motor plug into a three-line socket (the grounding protection must be
secure and reliable).
7. Shift the machine speed in to minimum, start the motor. After running the main
spindle for 20 minutes, check whether different parts have abnormal condition,
increase the speed progressively to continue the test run.
8. Prior to test run and formal use of the machine, you must first read this
instruction manual carefully. Understand thoroughly the basic construction of
machine tool, the operating procedure, the lubricating condition, securities and
maintenance etc., then you can operate the lathe.
