In this way, the maintenance of numerical control machine tools allows you to save a lot of costs！

The cost of a CNC machine is a highly dependent factor that is influenced by its size, target output, calculation software, durability, durability, accuracy, and multitasking. However, depending on the use and quality, the price of CNC machine tools ranges from tens of thousands to hundreds of thousands.Therefore, good maintenance can maintain the best machine tool processing accuracy, extend the service life, adopt the correct start-up debugging method for CNC machine tools, and in the face of new challenges, it is very important to show a good working condition, improve production efficiency and processing effect.

Maintenance of CNC machine shutdownThere are many types of CNC machine tools, and all kinds of CNC machine tools have different characteristics due to their different functions, structures and systems. The content and rules of its maintenance also have their own characteristics, and the necessary maintenance system should be formulated and established according to the type, model and actual use of the machine tool, and with reference to the requirements of the machine tool instruction manual. Here are some common general maintenance points.1. Machine tool cleaning: clean up the workpieces, fixtures, iron filings, etc. in the machine tool, and clean the iron filings in the external chip conveyor; The external sheet metal is wiped clean, and the air conditioner and oil cooler filter screen of the electric control box are cleaned.2. Anti-rust treatment: clean and wipe the workbench and smear it with anti-rust oil; The machine tool runs slowly for one hour to lubricate the line rails; Whether the cutting fluid needs to be replaced, priority is given to rust prevention, and the cutting fluid is added when the machine tool needs to work.3. Do a good job in the total power cut-off, gas cut-off, and liquid supply of the workshop: run the Y axis of the CNC machine tool to the middle, return the Z axis to zero, and turn off the total electric switch of the machine tool and the transformer inlet switch, gas source, etc.4. Waterproof and moisture-proof: close the electrical box for protection.5. Machine tool anti-rat treatment: The machine tool also does a good job of anti-rat treatment to prevent mice from biting off the wire.Start-up debugging of CNC machine toolsCNC machine tool is a kind of mechatronics equipment with high technical content, and it is very critical to start and debug in the correct way, which largely determines whether the CNC machine tool can play normal economic benefits and its own service life.Check before starting: Check the peripheral environment of the machine tool, whether the electrical box has abnormal phenomena such as water ingress, and whether the oil has deteriorated.Gradual start-up: Before starting, the power supply voltage of the machine tool must be detected, and the power switch must be turned on for about 10min after the voltage is stable, then turn on the power switch of the machine tool, and then open other power switches in the electrical box, check whether the voltage is out of phase and too low, turn on the power supply of the machine tool in the absence of abnormalities, and observe whether there is abnormal phenomenon and whether there is air leakage. When there is no alarm at startup, do not perform any action, let the electrical components be energized for 30min.Slow movement: check whether there is interference, move the machine tool with the handwheel, and pay attention to whether there is any abnormal phenomenon, and then perform the origin return step.Machine running-in: automatically run the machine tool slowly for a long time, and rotate the spindle at low speed.
