17) When the clamped workpiece is aligned, do not knock it hard to avoid shaking the head of the bed, or the chuck is loose and the workpiece may fall and cause an accident.
18) When using top clamps to top heavy workpieces, it must not exceed one-half of the full length.
19) The turning tool must be firmly stuck on the tool holder, and the tool head must not extend too long. Knife pads must be neat, and saw blades, rags, cotton yarn, etc., are not used as pad materials.
20) Before entering the knife, the positioning screws of the tool rest, center rest, and follower rest must be tightened.
21) When polishing with gauze, do not wrap the gauze on the workpiece and hold it tightly for polishing. The gauze must be stuck on a suitable wooden board or file for polishing.
22) When turning a hole, do not use a file to hand it. It is strictly forbidden to reach into the hole to touch the knife or the workpiece when the workpiece is rotating. Do not bring the head close to the rotating chuck or mold, and observe the cutting conditions in the hole.
23) When the machine tool is running, it is strictly forbidden to hold the die or tap to make a buckle by hand, and a special clamp must be used.
24) When grinding with a file when the locomotive is rotating, the file must be equipped with a handle. The operator should stand back and forth with both legs, with the right hand in front and the left hand in the back, with even force.

26) When processing eccentric workpieces, balance weights must be added, tightened firmly, brakes should not be too strong, and the speed should not be too fast.
27) There should be enough margin when cutting large materials, and then break them after unloading. Do not pick up the small material by hand when it is cut off.
28) When processing thin and long materials, use thimble, follower holder or center holder. The workpiece whose length exceeds 300mm from the inner hole of the spindle shall be supported by a bracket, and a protective railing shall be provided if necessary.
29) When parking, the tool should be retracted first, and then stop.
30) After the work is over, stop the operation of the machine tool, put the various tools used in the toolbox in an orderly manner, and stack the blanks, semi-finished products and finished products neatly.
