N. Umehara et al., INTERNAL POLISHING OF TUBE WITH MAGNETIC FLUID GRINDING .1. FUNDAMENTAL POLISHING PROPERTIES WITH TAPER-TYPE TOOLS, Journal of magnetism and magnetic materials, 149(1-2), 1995, pp. 185-187
In order to polish the internal surface of a long tube whose inner dia
meter is less than 20 mm, a new magnetic fluid grinding method for the
internal surface of the tube was developed. The obtained maximum remo
val rate was 0.28 mu m/min with 55 mu m of SiC abrasive and stainless
steel of taper-type tools. The obtained minimum surface roughness was
0.04 mu mRa with 1 mu m of SiC abrasives and PVA of the taper-type too
ls.
