“…Wang et al [9][10][11] applied silicone gel to mix steel with grits and silicon carbons as a gel abrasive, this gel abrasive could be closely wrapped around the cylindrical rod without magnetic forces and steel grits and silicon carbons would not fly away by the centrifugal force in MFGA. Their results demonstrated that surface roughness of the cylinder part was reduced to 0.1 m Ra from an initial value of 0.677 m Ra within 10 minutes, and surface roughness could down to 0.038 m Ra after 30 minutes in MFGA.…”

Toy clays made by bean gums or silicone gels can not only deform easily but also attach the undulate surface very closely. Flexible grinding tool can be produced to polish the un-flat surface by using above clays as abrasive media. Therefore, novel gel abrasives with permeability were developed to carry out magnetic abrasive finishing (MAF). In this study, bean gums or silicone gel with different viscosities were binding the steel grit and silicon carbon as gel abrasive with permeability. Magnetic finishing with gel abrasive (MFGA) was utilized in this study to polish the cylindrical rod of mold steel; furthermore, this cylindrical rod was fixed in a horizontal chuck that could rotate and vibrate in the axial direction. This study focused on the finishing efficiencies and the surface roughness of the workpieces after MFGA. Moreover, recycling times of gel abrasive were also the main effects that need to be approved. The results demonstrated that gel abrasive made by silicone gel with high viscosity would flowed away from the working area by centrifugal forces from rotating rod, inducing unstable efficiency in MFGA. However, gel abrasive produced by bean gum could resist centrifugal force and fixed in the working area, providing excellent polishing effect; therefore, surface roughness of cylindrical rod reduced from 0.65 mRa to 0.09 mRa within 5 minutes. Roughness improvement rate still remained at a high level of 90% when silicone gel with low viscosity (35 grams) was used 8 times to finish 8 workpieces, therefore, this result proved that the gel abrasive had excellent ability of the recycling.

“…Regardless of UMA or BMA, these abrasives cannot alleviate the drawbacks mentioned above after finishing. Wang et al [8][9][10] applied silicone gel to mix with steel grits and silicon carbides as the gel abrasive.

Magnetic abrasive finishing (MAF) is a fast and high-precision polishing method. However, the magnetic force acting on abrasive particles will decrease remarkably when polishing stainless steel tubes with the property of non-permeability, such as the SUS304 stainless steel. Moreover, the abrasive particles will be moved off the surface of machining area due to the centrifugal force of rotation, resulting in reducing the stability of polishing process. Therefore, this study developed a novel approach by adopting different gels as the bonding materials to combine the magnetic abrasive particles with hard abrasive particles to create a series of magnetic abrasive gels. Generally, those abrasive gels have higher viscosity to dominate the flow property that will constrain uniform motion of the abrasive particles in MAF, and the abrasive gels can be tightly contacted to the wall surface to increase the stability of polishing. This investigation utilized the optimal parameters out of Taguchi method to polish SUS304 stainless steel tube for 30 minutes—the value of surface roughness can be reduced from 0.636μm Ra to 0.05μm Ra, which can be improved by 92.1%, and the amount of material remove rate is as high as 218.4mg.
