What does magnetic abrasive mean?
With the rapid development of optics, electronics, communications, petroleum, machinery and biological engineering, many components with complex shapes and difficult to process materials have put forward more stringent requirements for ultra precision machining technology. In traditional machining technology, the finishing process is the method to obtain the lowest surface roughness. The so-called finishmachining, refers to the object to be machined surface quality greatly improved at the same time, realize the accuracy stability and even a technique to improve machining precision, is an important part of advanced manufacturing technology. The research and development of advanced finishing technology is of great importance to the development of modern manufacturing technology.
Magnetic finishing assisted by magnetic abrasive grains is an effective finishing method.(Magntic Abrasive Finishing, MAF MAF) the basic principle is the use of magnetic field, will visit the abrasive drawn together, forming a magnetic abrasive brush, applying relative motion in magnetic abrasive brush between workpiece and magnetic abrasive brush, magnetic abrasive particles in the surface of the workpiece will produce sliding, rolling, cutting and other sports. In order to achieve magnetic abrasive grinding on the workpiece surface.
The magnetic abrasive brush is formed by the free magnetic abrasive particles through the magnetic field, and has a certain flexibility and viscoelasticity. In the process of magnetic abrasive finishing, the grinding brush can change with the shape of the workpiece, so it can not only process foreign aid, spherical surface and plane surface, but also process free surface. In the process of free surface machining, there is no need for strict track control such as CNC grinding or CNC grinding and polishing. Is that since the lines of force penetration like X ray, can the traditional burnishing tools cannot penetrate, inner wall, micro groove surface after machining.
