Characterization of the Magnetic Abrasive Finishing Method and Its Application to Deburring

Technological Analysis of Flat Surface Conditions by Magnetic Abrasive Finishing Method (Maf)

“…The most important feature of this method is that the abrasive instrument has no bond; its function is performed by a magnetic flux in a working zone. These lead to arrange the cutting forces and also controlling the degree of elasticity by change of field strength [1][2][3][4][5][6][7][8] , via varying magnitude of the magnetic field in the machining zone, running clearance and the speed of rotation poles ( cutting speed) .…”

“…The MAF method gives combined effects on work piece which influence to surface layers of parts is conditioned by abrasive cutting, plastic deformation, electromagnetic adhesive effect and chemical processes [5,8,11,12].…”

Effective Deburring of the Burr at Intersecting Hole by Permanent Magnet Inductor

“…Magnetic abrasive finishing method has been used for finishing surface [1,2]. This technology also applied efficiently for internal surface finishing of the pipe, which is very difficult by traditional method [3].…”

“…This technology also applied efficiently for internal surface finishing of the pipe, which is very difficult by traditional method [3]. Recently MAF is proved as an efficient method for deburring the burr after drilling on exit surface [4,5]. For the micro burrs which cannot be removed easily, MAF could be used for deburring [6].…”

“…The magnetic inductor which uses permanent magnet has the weak point that it can't change the magnetic intensity as the electromagnetic one. However we can simplify the facility because it doesn't require extra devices like electric power supply device and it is easy to get access to burr because its size is remarkably small [2]. To determine proper operation condition for efficient deburring, rotational speed, table feed rate, use of coolant and other conditions are changed and the result is analyzed.…”
