Metallographic polishing lubricating and cooling fluid, specifically for metallographic sample grinding and polishing of the lubrication and cooling. Metallographic polishing lubricating coolant lubrication, cooling effect is good. For non-ferrous metals and iron metals softer grinding, polishing effect is particularly evident. Use the lubricating fluid and use the company's Metallographic polishing products, diamond polishing products, and metallographic polishing cloth thrown the system out of the sample, clean surface to eliminate the deformation microstructure and thus minimize the gold sample preparation phase microstructure of the real interference. Metallographic polishing lubricating coolant applicable domestic and foreign various models, specifications of metallographic polishing mill is particularly suitable for a variety of semi-automatic or fully automatic metallographic polishing mill, compared with similar foreign products, the nature of exactly the same.
