Do you know how to properly clean precision CNC machined parts? Engineering machinery parts basically need to be cleaned during the assembly process. Today, DO Machining will share several cleaning methods for precision CNC machined parts.
The purpose of cleaning parts is to remove all kinds of dirt, such as casting sand, iron filings, rust, abrasives, oil, dust, etc., remaining on the surface. The cleanliness of parts after cleaning will directly affect the assembly quality and the service life of engineering machinery, so the cleaning of parts is a very important part of the assembly of engineering machinery. To do a good job in the cleaning of parts, the correct selection of cleaning agents and cleaning methods should be based on their materials, structural characteristics, pollution and their cleanliness requirements.
There are 5 main cleaning methods for precision CNC machined parts:
1. Scrub
Put the parts in a container filled with diesel, kerosene or other cleaning fluid, scrub with cotton yarn or brush. This method is simple to operate, but low in efficiency, and is suitable for prototypes or small batch of small parts. In general, gasoline is not suitable for use because of its fat-soluble properties, which will harm people’s health and easily cause fires.
2. Boil wash
Put the prepared solution and the parts into a cleaning bath of appropriate size welded with steel plates, heat it to 80~90℃ with an under-pool stove, and cook for 3~5min.
3. Spray wash.
Spray a 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.
4. Vibration cleaning.
The parts to be cleaned are placed on the cleaning basket or cleaning rack of the vibrating washer and immersed in the cleaning liquid. The vibration of the cleaning machine is used to simulate the manual rinsing action and the chemical action of the cleaning liquid to remove oil stains.
5. Ultrasonic cleaning.
Rely on the chemical action of the cleaning liquid and the ultrasonic oscillation introduced into the cleaning liquid to remove oil stains.
DO Machining, a manufacturer of precision mechanical parts, reminds you: The cleaning method should be reasonably selected according to the causes and characteristics of the oil stain to ensure the normal use of the parts, avoid corrosion or damage to the parts, and prevent environmental pollution and subsequent contamination of the parts.
