"In my current position, we are asked to perform very regular maintaining on the CNC machine. It's an imperative and very costly piece of equipment that must be cared for regularly, and carefully. The schedule that I am accustomed to includes daily care checklist, a 500 hours checklist, a 1000 hours checklist, and a 2000 hours checklist. The daily checks that I perform include checking the hydraulic pressure to make sure it's at 4.5 MPa. I also check the hydraulic fluids, the chuck pressure, and lube level. The checklist also includes the cooling system, cleaning any loose chips out of the pan, and the window and lights. I also re-lubricate any necessary parts."
