In modern CNC machining, effective coolant management is key to precision, productivity, and machine longevity. Coolant tools help maintain the purity, balance, and efficiency of cutting fluids - from mixing and measuring to cleaning and recovery. This section introduces essential equipment designed for complete coolant maintenance in CNC workshops.
During machining, cutting fluids are constantly exposed to chips, tramp oils, and high temperatures. Over time, these factors degrade the emulsion, reduce cooling performance, and cause bacterial growth. Without proper monitoring and cleaning, tool life shortens, surface quality drops, and maintenance costs rise. To prevent this, CNC operators rely on specialized coolant accessories - refractometers, coolant mixers, vacuum air pumps, and chip skimmers - that keep the system clean and consistent.
A coolant refractometer measures the concentration and condition of your cutting fluid, ensuring the correct ratio of oil and water. It works by analyzing how light refracts through the emulsion - a simple, quick, and accurate way to check coolant quality directly at the machine.
The EASYCUT LQ20T Refractometer (0–20% Brix) provides automatic temperature compensation, fast readings, and reliable calibration for daily use in any CNC shop. Compact and durable, it’s the go-to tool for maintaining proper coolant concentration and preventing corrosion, bacterial growth, or premature tool wear.
Preparing a stable emulsion starts with accurate mixing. A coolant mixer automatically blends coolant concentrate with water at a fixed ratio, eliminating the guesswork of manual mixing. Consistent concentration means consistent cutting performance and fewer coolant-related problems.
The EASYCUT CS-30 Coolant Mixer delivers precise blending ratios and stable emulsions every time. It prevents foam formation and ensures the correct fluid balance for CNC lathes, mills, and machining centers, reducing coolant waste and machine downtime.
A vacuum air pump or fluid extractor helps remove used coolant, tramp oil, and sludge from CNC tanks and sumps. Using compressed air, it creates a strong vacuum for quick and safe fluid transfer without electricity. Most systems allow both suction and discharge functions for easy maintenance.
The EASYCUT APDQ1-25-I Vacuum Air Pump connects directly to a standard drum and features overflow protection, efficient suction, and simple pneumatic operation. It’s ideal for cleaning coolant tanks, removing oils, and maintaining a clean working environment around CNC machines.
Chip skimmers remove floating oils, chips, and fine debris from coolant surfaces, preventing contamination and extending the coolant’s service life. They play a critical role in keeping the coolant tank clean and maintaining high-quality cutting conditions.
The EASYCUT CFM100 Chip Skimmer efficiently separates tramp oil and contaminants, automatically removing them from the coolant surface. This reduces odor, prevents bacterial buildup, and improves the performance of filters and pumps in your coolant system.
Each of these tools serves a specific purpose in coolant care — refractometers monitor concentration, mixers ensure accuracy, vacuum pumps handle cleaning, and chip skimmers prevent contamination. Together, they form a complete coolant maintenance cycle that keeps your CNC systems running smoothly.
