The purpose of this report is to investigate the cause of deterioration of finishing performances in 0.45% plain carbon steel honing with increased cutting speed and to find out the conditions and means which enable to improve the finishing performances. At high cutting speed, difficulty of removal of continuous flow type chip brings the results that finishing performances deteriorate extremely over a limited range of cutting speed, where chip welds severely on stick and work surface, and after all annealed steel can be no more machined. Taking notice of cutting speed, this phenomenon is similar to the growth of builtup-edge in cutting operation. One method capable to hone successfully at high cutting speed is to use a sulfur treated porous stick with big spherical pores which works effectually to removal of chip, but it ended in failure to make a smooth surface. Another method is to apply a sulfurized fatty oil, and this application made it possible to operate honing successfully over all tested range of cutting speed. Because, this oil has the effect to remove chip easily by preventing it from growing and welding.
