  • In this paper, grinding characteristics of ultra high speed cylindrical plunge grinding was investigated by use of vitrified CBN wheel. From the experimental result, it was convinced that grinding power is decreased according to the increase of wheel and workpiece speed due to changing of grinding mechanism which decreases depth of cut and length of contact curve according to increment of wheel speed. And also, stock removal reduction of each gram lead to improvement of surface roughness by increasing the wheel speed.

  • In this paper, grinding characteristics of cylindrical plunge grinding in 200m/sec of grinding velocity was investigated by use of vitrified CBN wheel. From the experimental result, it was convinced that grinding power is decreased 2.5times and grinding efficiency is heightened 3times more according to increasing wheel velocity 80m/sec to 200m/sec And also, be expected to improvement of surface roughness and roundness by increasing the wheel velocity.
