Realization of efficient machining of difficult-to-cut materials with the help of ultrasonic waves

[Issue]
A ultrasonic assisted grinding machine for highly efficient machining of difficult-to-cut materials such as quartz and ceramics has been introduced, but a tool that can demonstrate this performance has been unable to find.


[Solution]
Tokyo Diamond Tools Mfg. Co., Ltd. has developed a tool that efficiently transmits resonant vibration to the work material in order to achieve highly efficient grinding using ultrasonic vibration. With the help of ultrasonic waves, highly efficient grinding of difficult-to-cut materials such as quartz and SiC ceramics can be realized.
With the aim of maximizing machining efficiency by taking advantage of the features of ultrasonic assisted machining, the bond specifications have been optimized to achieve both sharpness and wear resistance. In addition, a special control for dressing of abrasive grains is applied to the grain preparation to reduce grain slippage and achieve better biting on the work material compared to conventional products.
