Doing good maintenance can keep the machining accuracy of the machine tool in the best state and prolong the service life. By adopting the correct startup and commissioning methods for CNC machine tools, in the face of new challenges, it can show a good working state, improve production efficiency and processing results.
There are many types of CNC machine tools. Each type of CNC machine tool has different characteristics due to its different functions, structures, and systems. Its maintenance content and rules 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 by referring to the instructions of the machine tool manual. The following are some common maintenance points.
1. Machine tool cleaning: Clean the workpiece, jigs, iron chips, etc. in the machine tool, clean the iron chips in the external chip removal machine, wipe out the external sheet metal, and clean the filter of the electric control box air conditioner and oil cooler.
2. Anti-rust treatment: clean the workbench and wipe it with rust-proof oil; run the machine slowly for one hour to lubricate the rails; if the cutting fluid needs to be replaced, give priority to anti-rust treatment and add it when the machine needs to work Cutting fluid.
3. Do a good job in the workshop to cut off the power, gas, and liquid supply: Run the Y-axis of the CNC machine tool to the middle, return the Z-axis to zero, and turn off the machine's main electrical switch, transformer line switch, and air source.
4. Waterproof and moisture-proof: close the electrical box for protection.
5. Anti-rat treatment for machine tools: The machine tool also does anti-rat treatment to prevent rats from biting off the wires.
CNC machine tool is a kind of high-tech mechatronics equipment. It is very important to adopt the correct way to start-up and debug, which largely determines whether the NC machine tool can exert normal economic benefits and its own service life.
Check before starting: Check the peripheral environment of the machine tool, whether there is any abnormal phenomenon such as water in the electrical box, and whether the oil has deteriorated.
Step-by-step startup: The power voltage of the machine must be detected before the machine is turned on. The power switch of the machine must be turned on after the main power switch has been turned on for about 10 minutes before turning on the power switch of the machine. Too low, turn on the power of the machine tool without abnormal conditions and observe whether there is any abnormal phenomenon or air leakage. Do not perform any action when there is no alarm when the machine is turned on, and let the electrical components be energized for 30min.
Slow-motion: Check for interference, move the machine with the handwheel all the way, pay attention to any abnormalities, and then perform the origin return step.
Machine tool break-in: Automatically run the machine at a slow speed for a long time, and rotate the spindle at a low speed.
