Paper Title:
Ultrasonic Coring of Glass Disks Using Double Core Tool
  Abstract

Glass disks are used as substrates for the recording media in magnetic disk devices. To mass produce glass disks, a technology is required for machining glass (a material that is difficult to machine) with both high precision and high efficiency. Consequently, this study adopted a method that processes the inner- and outer-diameters simultaneously using a double core tool. In addition, the thrust force in coring process was also reduced using an ultrasonic spindle to apply ultrasonic vibration to the feed direction of the rotating tool. This resulted in high quality machining with less chipping. Furthermore, this study conducted experiments to compare the three methods of stabilizing the stack of glass substrates. As a result, it was found that the method using ultraviolet curable resin was able to limit the chipping to a smaller size.
