The FCG-105 precision filtration system was developed to address the varying particle size, mass and hardness of contaminants produced by different grinding materials. Suitable for quartz, silicon carbide, semiconductor grinding, EDM (electrical discharge machining) and high-precision machining, it effectively removes fine impurities from the fluid, including dust, emulsions, fine metal powders, ceramic powder, quartz, wire-cutting powder, aluminum powder, tungsten-carbide powder, grinding powder, screw-factory oil sludge and cast-iron powder, down to a filtration accuracy of 5μm. Widely used on lathes, milling machines, grinders, drilling machines, CNC, boring machines, planers, sawing machines and broaching machines.
Continuous or batch processing
Custom high-chromium-steel stirring motor
Audible filter-saturation alarm
Optional filter media — FCG-series filter cartridge
Operating principle
The FCG series uses a Japanese imported submersible pump to first stir and then draw in the waste; the impeller is made of hardened high-chromium steel to resist hard debris. The fluid is filtered through special filter media and recirculated continuously, increasing machine utilization with no downtime.
Filter-media flux curve
The FCG-105 filtration system is fitted with a high-performance filter cartridge whose media uses a three-layer special material and weaving process, achieving a filtration accuracy of 5μm and a flux of up to 110 LPM, filtering effectively while delaying saturation. Applications include EDM, straight-oil machining and grinding; for high-precision machining it effectively intercepts fine impurities. The filter cartridge is a consumable and must be replaced periodically. (The flux curve above is for a quartz-machining case and is for reference only.)
Which costs can improve
Continuous filtration means machining does not stop for a fluid change or tank clean; fines are removed as they are produced, so the fluid stays usable longer and both changes and waste handling become less frequent. The cartridge is a scheduled consumable whose replacement interval depends on workpiece material and powder load. The actual improvement has to be estimated from site conditions.
Results in use
Both straight-oil and water-based coolants can be filtered; the high-precision cartridge effectively filters fine chips and powder after machining, controlling the quality of the machining tank and automatically removing fine swarf, dust, emulsions, fine metal powders, ceramic powder, quartz, wire-cutting powder, aluminum powder, tungsten-carbide powder, grinding powder, screw-factory oil sludge, cast-iron powder and the like. When the media is saturated the warning light flashes automatically for easy management; high-performance precision filtration ensures the quality of workpieces (such as tungsten-carbide tools) and extends the life of the machine tool.
