First: there are many kinds of metal processing fluid, but most of the methods used are different. For water soluble metal processing fluid, it is necessary to use water for dilution. As for the proportion of metal processing liquid and water ratio, we can consult suppliers of metal processing fluid to us. What we need to note is that the quality of the added water must be in line with the requirements of the metalworking fluids, as the water also contains hard water and soft water.
Second: the use of metal processing oil is not the same as the use of metal processing liquid, metal processing oil can not add water, and do not need to add water, it can be used directly, no need to be diluted in use. But in metal processing, it is necessary to choose the metal processing oil with the required concentration according to the materials, methods and requirements that are processed.
Third: whether it is metalworking fluid or metalworking oil, when stored, store it in a cool and dry place to avoid direct sunlight. When used, follow the principle of advanced first out.
