What are the common problems in automatic lathe processing?

Problems that are prone to occur in the process of automatic lathes: unstable tapping depth, cause analysis and solutions: 1. Tapping limit pin wear. The wear of the limit pin will lead to inconsistent stop positions. The limit pin can be replaced to solve the problem. 2. The tapping belt is not tight enough, or the belt is worn and the belt is slipping. If the belt is too loose, you can adjust the adjustment screw at the back of the machine to a proper position or replace the belt. 3. The triangle belt of the tapping machine is too loose. You can loosen the four screws of the tapping machine and press it down and then tighten the screws. 4. The contact of the brake switch of the tapping machine burns black, replace the brake switch. 5. The brake pads of the tapping machine are worn out and the brakes do not work well. Replace the brake pads with new ones. 6. The tapping machine relay contacts are in poor contact, replace the relay. The outer circle is rough, the knife marks, and the size changes greatly. Cause analysis and solutions: 1. The chuck adjustment is not tight enough or there is slag in the chuck. If the chuck is too loose or there is slag inside, the material will not be clamped tightly. The movement of the tool during the turning process will cause the material to retreat and produce tool marks or The outer circle is rough when the material jumps. The chuck can be adjusted to a suitable state. 2. The camshaft is loose. When the camshaft is loose during the operation of the machine, the knife moves quickly and slowly or occasionally pauses, resulting in tool marks on the outer circle. The thimble of the camshaft should be tightened. 3. If the tool holder is loose or the slide inserts are worn out, the tool holder will swing, which will cause the outer diameter to be unstable. If the knife holder is loose, the small screws of the knife holder can be adjusted to fit tightly or the inserts can be replaced.
