Abstract

PURPOSE:To enhance the speed and efficiency of working and make it possible to constantly obtain stable accuracy by enabling a part to radially oscillate, in addition to constant swinging oscillation of a spindle by a converter. CONSTITUTION:A converter 2 is fitted on the rear end part of a shaft core 1' coupled to a motor, and a booster 3 provided with a fixing mechanism 4 for fixing a grindstone 5 is coupled to the center part of the shaft core so as to form a spindle 1. In addition to this spindle 1, ball bearing 6 are fitted on the spindle 1 with the use of stepped parts or the like. Further, thus arranged spindle are rotatably supported by bisplit covers 7, 7', entirely on both sides thereof, excepting the booster 3 and parts in the vicinity of the center of the grindstone 5 which extends orthogonal to the spindle 1. With this arrangement in which the bearings 6 are fitted on both side parts of the spindle 1, it is possible to obtain stability and as well high rotational speed, and therefore, it is possible to enhance smooth performance. Further, the phenomenon of acceleration together with ultrasonic operation produced by the converter 2 causes slight radial expansion and contraction, thereby it is possible to maintain a fine grinding function.

As is well known, conventionally used ultrasonic rotary processing machines generate ultrasonic vibrations using a converter equipped with a physical electrostrictive element (vibrator) such as lead zirconate titanate that generates 20 kilohertz. This is a grinding machine that mainly performs cutting and drilling using high-speed rotation, and targets materials such as alumina, glass, ferrite, quartz, as well as sapphire, zirconium, or beryllium oxide.

Made of boron compounds, etc., it is well suited for hard and brittle materials, and can be used for slicing, threading, polishing, and cutting in a short time.
Although it is a grinding machine that can perform processing such as milling, it is not possible to minimize the clogging of the grindstone that occurs when working with high-speed rotation and oscillating vibration, or to apply stable expansion/expansion amplitude in the radial direction. For this reason, it has been extremely difficult to improve the precision and performance of many of the components used.
