　　PCB engraving machine is a kind of drilling and milling combined processing in principle. There are many data input modes of PCB engraving machine, which can be easily accessed according to needs. There are two kinds of computer engraving machines, laser engraving and mechanical engraving, which are divided into high power and low power. Now let's talk about how to avoid the rust of the engraving machine.

　　The parts of PCB engraving machine are easy to be oxidized. Once oxidized and rusted, the accuracy of the engraving machine will be affected, and the useful life of the engraving machine will naturally be shortened. It is equivalent to greatly increasing the service life of the engraving machine if you want to extend the service life of the engraving machine, you need to strengthen the daily maintenance and protection to avoid the rusting of the engraving machine.

　　1. The appearance of steel parts, such as ball screw, quenched steel raceway of rolling guide rail and steel fastener, should be dipped in butter with cloth or cotton every few days. Other parts, should often observe whether there is weak small rust, if there is rust, the application of cloth oil to erase, and as the focus of future anti-rust.

　　2. Aluminum parts should also be coated with cloth dipped in butter every few days, or a varnish can be sprayed. It is often observed whether there are any pits.
