Magnetic coolant cleaners are often the best solution.

Keeping coolant clean means conserving cash, and in today's cost-conscious business environment, that's a requirement. Manufacturers of machined parts, like everyone in business, are constantly looking for ways to reduce costs and improve their processes. One very attractive approach to cutting costs in production operations is utilizing super-strong magnets to keep coolant clean.

Changing coolant is frequent because stock removed from workpieces fills the coolant reservoir. If the fines (small particles) are ferrous, magnetic coolant cleaners can provide the best filtration for the least amount of money and permit recycling of the coolant. Thanks to the improved strength of today's magnets, coolant cleaners are more efficient and effective than ever before.

The economic payback of coolant cleaners is huge. Advantages include extended coolant life, savings on traditional paper or bag filter media, longer life of cutting tools, better finish and tighter tolerances on parts being machined, savings on labor and maintenance associated with changing traditional media and maintaining traditional filtration equipment, and increased machine up-time from lower maintenance requirements. Additionally, clean coolant contributes to a cleaner, healthier work environment, resulting in overall better working conditions for employees.

Today, environmental consciousness is high. However, this was not always the case. Before enactment of the present EPA and RCRA regulations, disposal of used metalworking coolants and filtration media was neither especially difficult nor particularly costly. When the shift to stricter regulations occurred, disposal of used machining coolant became a very real concern. When machining heavy metal alloys with lead, chromium, nickel, or other toxic heavy metals as an ingredient, the coolant may be considered hazardous waste, depending on local EPA regulations. That is why the less material there is to dispose, the better. And one way to reduce disposal of machining coolant is to clean and recycle it.

Recycling means that the cool ant has to be cleaned and reused. Cleaning includes re moving any ferrous materials that get into the coolant.

Magnets

The advent of rare earth permanent magnets has enabled the design of high-intensity magnetic circuits operating without electrical energy. Magnetic circuits now generate a magnetic force of an order of magnitude greater than the convention al ferrite magnets that were used in the past...
