Requirements for coating technology of machine tool bed casting:
To check on the bed casting 1, machine tool bed casting before painting, the use of tools to reshape the uneven surface, the dirt on the surface to be cleared.
2, through mechanical processing after the bed casting, must carry on the leaching or scrub with metal cleaning agent or clean industrial gasoline before painting, to ensure complete removal of surface oil and other contaminants.
3, bottom paint coated or sprayed, leaching should be uniform, primer must be fully mixing before use, and diluted to appropriate annual then daub.
4, filling casting sag putty according to the use of the product description to join the right amount of curing agents, must be fully stir before use.
5, if the depression using perchloroethylene filler bed casting, every scratch shoulds not be too thick, scraping thickness in 0.5 mm or so, each time must wait by scraping scraping material dry after.
6, the use of perchloroethylene filler bed casting depression after must wait for the dried before grinding, polishing after every time all need complete removal of grinding and dust on the surface of the.
7, using the watermill technology for grinding, in order to prevent the machine tool castings processed surface rust, need to use anti rust water grinding.
8, after polished, if there are metal exposed phenomenon, need not brush matched primer.
In 9, the last to putty grinding after cleaning, need to spray a vinyl chloride second primer, this can increase the film roughness, increased the film gloss.
