What cutting fluid is used for cylindrical grinder? What brand is the cutting fluid?

When finishing grinding, if cutting fluid with good cleaning and lubricity is used, the product smoothness and machining efficiency can be improved to some extent. The first important index of using water-based cutting fluid is rust prevention, followed by service life. It is very suitable to use cutting fluid C2 1 for grinding. Water-based cutting fluids are emulsified, semi-synthetic and fully synthetic. Emulsified, oil content (> 40%, oil particle diameter in emulsion is 0. 1~ 10μm), oil content is lower than that in emulsion (20~40%, oil particle diameter in emulsion is generally below 0. 1μm), oil content is very low or not, generally speaking, high oil content is beneficial to the boundary. Processing (grinding) with high requirements for cooling and cleaning generally adopts fully synthetic products; The semi-synthetic combination of the two has better universality.
