Appropriate Selection of Metalworking Fluids
Metalworking fluids (MWF) are used in the production of most metal products. The selection of the most appropriate fluis is critical to the success of the production. In this article, the major factors to consider when selecting MWF will be discussed, as well as some general guidelines for when and why certain types of MWF may be best suited for certain applications.
The first factor to consider when selecting a MWF is the type of metal being worked. Because different metals and their alloys interact differently with fluid, it is important to select a fluid that is compatible with the particular metal being worked. Using a fluid that is not compatible with the metal can lead to corrosion, abrasion of the material, and other issues. It is also important to consider the temperatures at which the fluid will be used, as some fluids can become unstable or even hazardous when heated to a certain degree.
The second factor to consider is the purpose of the fluid. In most cases, machine operators are looking for a fluid that will both cool and lubricate the cutting process, thus reducing friction and wear. There are a variety of options for selecting an appropriate MWF, some of which include mineral-based oils, semi-synthetic fluids, and synthetic fluids. The selection will ultimately depend on the particular application and the required performance.
The third factor to consider is the length of time the fluid will be used. In most cases, fluids are used in short bursts, such as with machining operations. In these cases, mineral-based fluids are likely to be the most cost-effective and efficient choice. In other cases, however, the fluid may be used for longer periods of time and then need to be changed. In these cases, synthetic or semi-synthetic fluids may be more suitable, as they provide longer lasting performance and can tolerate higher temperatures.
Finally, the fourth factor to consider is the environmental impact of the fluid. This includes both the disposal of the fluid and the maintenance of the equipment used. In this regard, it is recommended to select a fluid that contains biodegradable and non-hazardous ingredients. Additionally, it is important to select the most efficient equipment for the job in order to reduce waste and minimize the amount of fluid used.
In summary, selecting the most appropriate MWF for any given application is a complex process and one that requires careful consideration of a number of factors, including the type and purpose of the metal being worked, the temperatures at which the fluid will be used, the length of time the fluid will be used, and the environmental impact of the fluid. By taking all of these factors into account, machine operators can ensure that the right fluid is chosen for the job and that their production processes are as efficient and cost effective as possible.
