Grinding Performance of a Grain-Arranged Diamond Wheel against Industrial Pure Aluminum

Abstract

A grain-arranged diamond wheel is developed and grinding performance of the wheel against industrial pure aluminum, one of the most hard-to-grinding materials, is investigated. The developed wheel efficiently ground pure aluminum without adhesion even when general-purpose grinding fluid, Type A3-1, was used. Moreover, wheel wear was not observed during the experiment, and grinding energy was extremely low. By using the developed wheel, a mirror surface can be easily obtained by one-pass surface grinding with very low table speed.

Grinding Performance of a Grain-Arranged Diamond Wheel against Aluminum Alloys and Ti6Al4V

“…where, υ is average cubic-spacing of cutting edges, γ is half of average vertical angle of cutting edges, D is wheel diameter, d is workpiece diameter, and m is multiplier. For the grain-arranged wheel the value of m is experimentally confirmed to be about 1.0 [2]. In the case of horizontal milling, the surface roughness in cutting direction can be written as,…”

“…the same crystal type must be selected, (2) face and direction of diamond crystals must be correctly arranged on the wheel surface, and (3) the wheel surface must be lapped more precisely. However, these ideal conditions would not be easily applied.…”

“…The authors previously developed a grain-arranged diamond wheel of #45 in mesh size in order to enhance the grinding capability against industrial pure aluminum, which is one of the most hard-to-grind materials [2]. The wheel with fine truing showed excellent performance in grinding energy consumption and surface finishing.…”
