Flexographic printing machines, like other machines, cannot work without friction. Lubrication is to add a layer of fluid material-lubricant between the working surfaces of the parts that are in contact with each other, so that the rough and uneven parts on the working surface of the parts are in contact as little as possible, so that they produce less friction when they move with each other. friction. Each part of the flexographic printing machine is a metal structure, and friction occurs between the metals during the movement, which causes the machine to be blocked, or the machine precision is reduced due to the wear of the sliding parts. In order to reduce the friction force of the machine movement, reduce the energy consumption and the wear of the parts, the relevant parts must be well lubricated. That is to say, inject lubricating material on the working surface where the parts are in contact, so that the friction force is reduced to a minimum. In addition to the lubricating effect, the lubricating material also has:
① cooling effect;
② stress dispersion effect;
③ Dust-proof effect;
④ Anti-rust effect;
⑤ Buffering and vibration-absorbing effect.
