RESEARCH OF THE GRINDING PROCESS USING MAGNETIC ABRASIVE SUSPENSIONS
Prospects for the use of magnetic abrasive suspensions in grinding cylindrical bodies made of metallic and non-metallic materials using kinematic schemes with forced rotation of cylindrical tools or with free rotation of conical tools are substantiated. The advantages of using a kinematic scheme with forced rotation of a cylindrical abrasive tool at the stage of pretreatment of leucosapphire pipes are shown. The advantages of the main surface treatment of leucosapphire pipes with free abrasive, which is part of the magnetic suspension, when using a conical tool with free rotation are shown. A mathematical model is proposed that reflects the relationship between the magnetic moment of the magnet, the geometry of the tool and the distribution of the magnetic abrasive suspension in the cutting zone. The results of numerical experiments and control field experiments are presented, confirming the high efficiency and cost- effectiveness of using a magnetic field and magnetic abrasive suspensions when grinding products made of metallic and non-metallic materials with a free abrasive.
