The CNC machining center will be contaminated with dirt during processing and operation.
In order not to affect the normal operation of the equipment, correct cleaning and decontamination methods must be adopted in actual maintenance work, which can quickly and effectively clean the dirt without damaging the parts. Common decontamination methods are as follows:
- Scrubbing: Put the parts in a container filled with diesel, kerosene or other cleaning fluid, and scrub with cotton yarn or scrub with a brush. This method is easy to operate, simple in equipment, but low in efficiency, and is suitable for a single small batch of small parts. Generally, gasoline is not suitable for use because of its fat-dissolving property, which will harm human health and easily cause fire.
- Spray cleaning: spray cleaning fluid with a certain pressure and temperature onto the surface of the parts to remove oil stains. This method has good cleaning effect and high production efficiency, but the equipment is complicated, and it is suitable for cleaning parts with less complicated shapes and serious grease stains on the surface. Vibration cleaning: Put the parts to be cleaned on the cleaning basket or cleaning rack of the vibration cleaning machine, and immerse them in the cleaning liquid. The vibration generated by the cleaning machine simulates the manual bleaching action and the chemical action of the cleaning liquid to remove oil stains.
- Ultrasonic cleaning: Rely on the chemical action of the cleaning liquid and the ultrasonic oscillation introduced into the cleaning liquid to remove oil stains.
- Boil and wash: Put the prepared solution and the parts to be cleaned into a cleaning tank of appropriate size welded with steel plates, heat it to 80~90℃ with an under-pool stove, and cook for 3~5min.
Due to the different nature of the parts, care must be taken in the selection of decontamination methods and decontamination agents.
