The cleaning method of large CNC Machining centers is a meticulous and important process, which directly affects the operating accuracy and service life of the machine tool. The following are a series of cleaning steps and suggestions to ensure that the machine tool is in good condition: 1. Preparation stage: ① Prepare tools and equipment: clean cotton cloth or special wiping cloth, vacuum cleaner or air gun (used to clean difficult to reach corners), cleaning agent (choose the appropriate cleaning agent for the machine tool material), lubricating oil and grease, screwdriver, wrench and other tools (used to remove and install protective covers and other components). ② Power off: Before performing any cleaning work on large CNC machining centers, be sure to turn off the main power switch of the machine tool to ensure that it is in a power-off state to prevent electric shock accidents. 2、 Daily cleaning ① Cleaning the exterior of the machine tool: Use a clean cotton cloth or wiping cloth to wipe the machine tool housing, control panel, display screen and other components to remove dust and oil stains. Be careful not to use cleaning agents containing corrosive substances to avoid damaging the surface of the machine tool Cleaning the interior of the machine tool: Open the protective cover and electrical cabinet door of the machine tool, and use a vacuum cleaner or air gun to clean the dust and chips inside the machine tool. Pay special attention to cleaning the machine tool track, guide rail protective cover, spindle taper hole, tool magazine arm, and tool compartment, which are prone to accumulate dust and chips, affecting the accuracy and service life of the machine tool Clean the guide rail and screw: Use a brush and cleaning agent to remove chips and dust from the surface of the guide rail and screw. After cleaning, apply an appropriate amount of lubricating oil or grease to reduce friction and wear Clean the grating ruler and other sensors: Use a clean cotton cloth to gently wipe the surface of the grating ruler and other sensors to ensure that they are not affected by dust and chips. 3、 Regular deep cleaning: ① Clean the oil tank and filter screen: Large CNC machining centers regularly clean the oil tank and filter screen of the machine tool to remove oil stains and impurities, ensuring the cleanliness of the oil. Replace aged lubricating oil and coolant to maintain the lubrication and cooling effect of the machine tool Check and replace vulnerable parts: Check the vulnerable parts of the machine tool, such as cutting tools, pull bolts, bearings, etc. If there is wear or damage, they should be replaced in a timely manner. Clean and check whether the movements of the tool magazine and tool changing arm are smooth, and adjust them if necessary Cleaning electrical system: Inspect and clean the electrical system of the machine tool, including components such as power supply, control panel, sensors, etc. Check if the wiring is loose or damaged, repair and tighten it in a timely manner. 4、 Other precautions: ① Keep the environment around the machine tool clean: The area around the machine tool should be kept clean and tidy to avoid dust and debris entering the interior of the machine tool. Regularly inspect and clean the ventilation openings and heat dissipation devices around the machine tool to ensure the heat dissipation effect of the machine tool Regular maintenance and upkeep: Perform regular maintenance and upkeep according to the machine tool's user manual and maintenance manual. Including checking the accuracy of the machine tool, the tightness of fasteners, and the lubrication of the transmission system Professional training: Large CNC machining centers provide professional training for operators to understand the structure, working principles, and cleaning and maintenance methods of the machine tool. Improve the skill level and maintenance awareness of operators to ensure the correct use and maintenance of machine tools.
