Better ground surfaces.
No further quality complaints.
An automotive steering-component manufacturer installed FMF 420/6 magnetic filtration to improve grinding coolant cleanliness. Subsequent sample analysis found no detectable particles. Component surface quality improved substantially, and no further grinding-quality complaints were recorded. The customer then fitted a second system with the same filter.
Case background
The manufacturer grinds automotive steering components to high precision. The demanding quality specification requires scratch-free surfaces and a uniform grinding pattern.
The challenge
To achieve the required surface quality, the grinding coolant must be exceptionally clean. Particles entering the contact zone between the grinding wheel and the workpiece can create deep scratches or grooves and cause rejects.
Cartridge filters with different ratings were already in use. Although coolant cleanliness was relatively good, complaints about the grinding pattern continued.
The company sought to remove as many fine particles as possible, including particles below 1 µm, without high consumable-filter costs.
The Solution
Installing a FRIESS FMF 420/6 magnetic filter significantly improved coolant cleanliness. Subsequent particle analysis found no detectable particles in the coolant delivered through the nozzles to the grinding wheel and workpiece. The cleaner coolant substantially improved component surface quality.
The Results
Since the magnetic filter was installed, no further complaints about grinding surface quality have been recorded.
Following this successful result, a second system was equipped with an FMF 420/6 magnetic filter.
