Study on magnetic preparation of dual disk based on silica gel magneto-elastic abrasive particles

Magneto-elastic abrasive grains have magnetism, low elastic modulus and excellent performance, the characteristics of bonded loose grains. The dual-disk magnetic preparation greatly improves quality efficiency. Firstly, magneto-elastic particles are introduced into edge tool, method 4035 silica gel is proposed. According to microscopic particles, finite element software ABAQUS used establish particles. meso-level representative volume (RVE) model built analyze stress strain law under tension compression. Secondly, an experimental platform for with dual disks was force Finally, Through experiment force, influence disk rotation speed, particle size relative permeability on cutting wear studied. And compared double-disk drag finishing method, can obtain maximum amount surface roughness decreasing amplitude. research results great significance promote progress our country's high-efficiency processing magneto-finishing technology.
