1、外文资料2The magnetic machining technology Use the magnetic field generated by abrasive grinding pressure magnetic mechanical polishing surface finishing another new technology. Currently, the right components within a round face, cylindrical surface, plane. Molding and so on the surface of the complex
2、shape of small and medium parts of the surface magnetic machining development and research. From the principle of speaking, it can be any geometric shape of the surface of precision finishing. Therefore, there is a broad prospect, will produce good economic and social benefits.The magnetism grind of
3、 process principle Given one pair of poles, between the two poles of a magnetic field formed, full of the energy and intensity generated magnetic induction. If a magnetic filled with both magnetic and has cutting ability of composite mill Magnetic Abrasive, Abrasive grains will closely ,and with the
4、 rules and form a magnetic brush. Magnetic Abrasive grains in the magnetic brush, if home work piece, magnetic brush will be the magnetic pressure in the form of role in the work piece surface. In order to achieve the surface of the work piece machining, work piece also must give way to the campaign
5、-rotation and axial vibration. With the work piece and Magnetic Abrasive grains relative movement between the produce, Magnetic Abrasive grains on the work piece surface rough, and the burr edge, corner are all magnetic induction intensity and the magnetic field lines were concentrated, so they were
6、 the first to be processed, to the removal of burrs and surface finishing purposes. Magnetic grinding process, the single abrasive the magnetic field, maintaining the magnetic field strength and tangential to the common role of friction, so abrasive to maintain stability in the process space. Implem
7、entation of the work piece surface grinding process. At the same time the processing region external magnetic abrasive grains because of the strength of the magnetic field,will automatically go to the work piece machining regional pool, filling in the pole between the work piece and in the processin
8、g, formed a complete and continuous processing.Abrasive grinding mechanism In magnetic ground processing, magnetic powder abrasive grain is a grain group, by the magnetic field in magnetic pressure and the role to the work piece surface. Abrasive the force as mentioned above. According to the theory
9、 of precision cutting and Moldova rub theory, we can see the magnetic abrasive grinding machining and work piece surface contact sliding rub, squeeze, Characterizations and cutting phenomenon . Thus the magnetic grinding mechanism mainly include the following 1、Trace Cutting and extrusion; 2、Multipl
