In CNC machining, metal stamping, and grinding operations, water-soluble coolants and cutting oils quickly become contaminated with fine metal swarf, tramp oils, and abrasive grinding dust. Contaminated coolants cause tool wear, poor surface finishes, and rancid bacterial odors. Installing Magnetic Separators & Cartridge Filter Housings extends coolant life and protects high-precision machining tools.
Critical Stages in Coolant Recovery
-
Primary Magnetic & Bag Pre-Screening: Heavy-duty bag filter vessels or magnetic strainers strip out large iron shavings and chips before fluid enters settling tanks.
-
Tramp Oil Separation: Coalescing media inside dedicated vessels removes floating tramp oil, depriving anaerobic bacteria of the seal that causes foul coolant odors.
-
Fine Micro-Polishing: High-capacity pleated polypropylene cartridges remove micro-abrasive metallic fines down to 5 microns, protecting high-pressure through-spindle coolant pumps.
Core Advantages for Machine Shops
-
Doubles Coolant Lifespan: Reduces hazardous waste disposal costs and fluid replacement purchases.
-
Protects Cutting Tools: Clean coolant reduces friction, heat build-up, and premature tool tip failure.
-
Improves Part Finishes: Keeps grinding wheels and cutting bits free of recutting metal fines.
