With the different types of band saw parts available, it is important to choose the right one for your hardworking machine. If you are considering soluble oil, you have to closely examine its true value because some may have a combination of fatty oils, chlorinated materials, and other additives. Emulsifiers are usually added to enable these incompatible oil components to mix well with water. Just keep in mind, that this mix does not remain permanent and can separate to various degrees, particularly when left unused for long periods of time.
If your sawing application involves high-production operations, the most practical band saw parts application method is a flood system that both infeed and outfeed sides of the material. Another type of band saw parts is synthetic fluids. Unlike the soluble oils, synthetic fluids do not scale in the sump tank. They are oil-free concentrates and are heavy-duty, contain EP additives and corrosion inhibitors, and are tolerant of water with high mineral content. Better yet, they are eco-friendly because they are non-toxic, and once they are mixed, they provide true cooling solutions.
A high-quality synthetic coolant has a greater initial cost than soluble oil because it is formulated to provide better performance over a wide range of materials being cut and overcome time-consuming issues up-front. As such, you might find a synthetic fluid to be more cost-effective in the long run. However, just like any other bandsaw coolant type available, it must be disposed of as dangerous waste once it becomes mixed with metal chips in the bandsaw reservoir.
Finally, another type of bandsaw coolant is the semisynthetic fluid which contains a synthetic-based product that has some soluble oils for corrosion resistance and added lubrication. This kind of coolant provides the best and the worst of both synthetic fluid and soluble oil. Because of the presence of the oil, cut materials have to be cleaned first before they are welded or painted, depending on the specific kind of additive mixed.
