The cutting machine does not work due to mechanical failure. The main reasons are: too large deformation of the body, oil shortage of the column guide, and the falling off of the pin and connecting rod, which cause the machine to jam, etc. The probability of the cutting machine not working due to mechanical failure is 1,000 points. One, so when the cutting machine does not work, generally, mechanical failures are not given priority. Mechanical failure is easier to find, but as long as it is a mechanical failure that causes the automatic cutting machine to not operate, it is more troublesome to repair, relatively time-consuming and laborious, and it may even be returned to the factory for repair. Generally, you can see the fault at a glance by opening the guard around the machine.
