Metalworking is the process of working with metals to create individual parts, assemblies, etc. To prevent burning and smoking, metalworking fluid (MWF) is the most important role which is the name given to a range of oils and other liquids. During machining, MWF is used to reduce heat and friction, and to remove metal particles, to cool and lubricate metal work-piece.
The oils, coolants and lubricants used in metalworking shops are often overlooked as an opportunity to improve process efficiencies. However, the standard machining or grinding shop sees the lubricant and coolant as the least important factor in the total cost of machining and the last place to look for process improvements. Metalworking fluids work well, until they don’t. And when they go wrong, it can be a show stopper.
We are going to sharing more articles about metal working for your reference as below. For sure, if you have any unclear or MWFs questions, you can click contact us or email to our service directly.
All-purpose cutting oil is commonly used for each machining that it can suitable for various metal materials. But is it enough? As we know, there are many sort of cutting fluids in the market. So how to choose the right cutting oil? At first, metal and machining operations which you need to gather some basic information relevant to the selection criteria.... Read More
Neat cutting oils are based on mineral oils, and blended with additives, and used for cutting without further dilution as supplied by the manufacturer. Besides, neat cutting oils have superior lubricating and cutting performance which prevents corrosion and rusting and also increases the life of the machinery and tools made of metal.... Read More
Water Soluble cutting fluids are form an emulsion when added to water. These emulsifiable oils are mineral oil based concentrates, which contain emulsifiers that allow them to mix with water and form a milky white emulsion. They also contain additives to improve their lubricating properties, rust and corrosion inhibitors and a biocide to help control foul smell. Read More
The most important requirements to be met by coolants in metal cutting are reduction of tool wear, a high-quality surface finish and economy of use. Most of factories replaced neat cutting oils with water-dilutable cutting coolants. Read More
Cutting fluids serve a number of key lubrication functions, cooling to preserve tool life, remove chips, and surface protection to preserve the machined part from corrosion. The usage and environment of metal cutting fluids cause them to change over time. Therefore, fluid maintenance is crucial for a better application of the fluid.... Read More
The most common cutting fluid problems encountered by manufacturers (users) typically fall into the following five areas: foam, corrosion, residues, odor and dermal irritation. Most metal cutting fluids, in addition to cooling and lubricating which also have good cleaning properties to help keep machines clean. However, they also foam when agitated.... Read More
Metalworking fluids(MWFs), mainly used as 2–10% emulsions in water which are among the commonest chemical exposures. Most MWFs are mixtures of base oil and auxiliary substances such as emulsifiers, antimicrobial agents, corrosion inhibitors, extreme pressure additives, etc. which are strongly alkaline, and contact with skin can remove natural oils and damage the proteins in the skin's protective outer layer so that skin's water content is diminished, and the result is dry, scaly, inflamed skin....

If you’ve worked in a machine shop or metalworking facility for any length of time, you have no doubt encountered a variety of unpleasant odors. Perhaps you’ve noticed that “rotten egg” or “Monday morning” smell (bacteria) when metalworking coolants are allowed to “rest” over the weekend, usually under a blanket of surface tramp oil. Regardless of any situations, your nose is alerting you to the serious problem of microbiological growth in your water-based metalworking fluids. Bacteria grow in coolant sumps, producing a nasty smell and biomass that can clog filters and screens.... Read More
Product qualification is the process of certifying that a certain product has passed performance tests and quality assurance tests, and meets qualification criteria stipulated in contracts, regulations, or specifications (typically called "certification schemes" in the product certification industry). To protect customer benefit and control product security, product certification is nessary. There are a few certifications which HAI LU JYA HE CO., LTD have, like RoHs, Reach, TGRS. Read More
