composition analysis of metalworking fluid products

metalworking fluids are fluids used mainly for metalworking, mainly for lubrication and cooling, but also for rust prevention and cleaning. general metalworking fluids include cutting fluids, cutting oils, emulsions, stamping oils, quenching oils, quenching agents, high temperature oils, extreme pressure cutting fluids, grinding fluids, rust prevention oils, cleaning agents, blackening agents, deep drawing oils, thickeners, etc. metalworking cutting fluids are low foaming, high lubricity soluble lubricants that minimise maintenance costs even when used in demanding environments. and cooling.

there are four main functions of metalworking fluids, one is to cool, take away the large amount of heat generated by cutting and plastic deformation, and prevent the welding and prop strength between the friction surfaces from decreasing; the second is to reduce frictional wear, change the friction state, speed up cutting, extend the life of the tool or mould, and improve the surface finish of processing, the third is to flush away the cutting, and the fourth is to prevent rust, so that the surface of the workpiece with cutting fluid has a short-term anti-rust effect.

as human beings realize the importance of environmental protection of the earth on which they live, they put environmental protection in the first place. the research, production and use of metalworking oils (fluids) must first meet the requirements of environmental protection regulations and must take into account the protection of workers' health and safety, whether they are harmful to the environment, and the disposal of waste fluids after processing. the composition of various metalworking fluids must therefore be non-toxic, low odour, low oil mist, long life, low waste disposal costs and biodegradable. environmentally friendly metalworking oils (fluids) have been an important topic of research in recent times. synthetic fluids are the direction of development for metalworking oils (fluids).

q&a

what are the main categories of cutting fluids and what are the disadvantages of each product?

cutting fluids are mainly divided into water-based cutting fluids and cutting oils, water-based common are fully synthetic cutting fluids, semi-synthetic cutting fluids, emulsions. fully synthetic cutting fluid products have poor rust prevention, insufficient lubrication, relatively low cost and long life, semi-synthetic cutting fluid products have poor rust prevention, insufficient lubrication, foam, emulsion products have short life and easy to smell, cutting oil has high cost, heavy oil mist and health hazards.

what is the machining process for cutting oils?

cutting oils are compounded systems in which rust inhibitors, lubricants, extreme pressure agents, rust inhibitors, defoamers, film formers, some with emulsifiers, are added to the base oil and stirred until well mixed, requiring heating if necessary.

as the metalworking fluid industry is becoming more environmentally friendly, what support can noa provide to companies in this area?

noa can test metalworking fluid products for voc and hazardous substance limits in accordance with national standards to determine whether they can meet national environmental standards; at the same time, noa has the ability to analyse and develop new products to help companies develop new products in the direction of environmental protection such as water-based products.

what is noa lab's better solution for product enhancement when it comes to poor stability of metalworking fluid emulsions, foaming problems in machining fluids, and smelly machining fluids?

equipped with high-precision instruments and professional technicians, noa's testing laboratory is able to provide technical services such as formula optimisation, raw material recommendation and process guidance to help enterprises achieve product performance improvement and reduce production costs.
