MAGNETO-ABRASIVE MATERIALS AND METHODS FOR OBTAINING THEM
Journal Title: TEHNOMUS - Year 2013, Vol 20, Issue 1
Abstract
Magnetic abrasive particles (MAPs) are crucial to ensure finishing quality and accuracy in magnetic abrasive finishing (MAF) processing. Conventional MAPs consist of ferrous particles and abrasive, such as Al2O3 , SiC, ZrO2 , B4C as well as diamond, cubic boron nitride, MgO, CeO2 or fumed silica. The MAPs can be used as unbounded, loosely bounded or bounded. Here, ferrous particles, which are mostly conventional used magnetic particles in MAF process, provide force of grinding via magnetic field. But due t o the corrosion and softness of ferrous materials, the post - cleaning of the surface finished by the MAPs containing ferrous particles becomes the most time - consuming and critical procedure in some ultraprecision MAF processing, other magnetic particles are urgent to need be developed to replace the conventional ferrous particles.
