The Research of NC Magnetic Abrasive Finishing for Mould Parting Surface

Abstract:

In this paper, a new kind of NC magnetic abrasive finishing method with meshy polishing track to grind the parting face of mould was presented, and a new simple polishing tool using permanent magnet was also developed. Using the magnetic polishing tool, 3D NC polishing experiments was conducted on 2D parting surfaces. Experimental results reveal the relationship between several main parameters (rotational speed of magnetic pole, working gap, feeding speed and number of polishing times) and surface roughness. This study is expected to be helpful to improve the efficiency of finishing process, reduce worker's labor intensity, realize the effective control of finishing process and obtain fine quality of workpiece surface.
