Abstract

PURPOSE:To accurately, detect the contact between a tool and a work by shortcircuiting a second electric circuit, when a tool and work are in contact with each other, utilizing the resistance of a lubricating oil for a bearing in a first electric circuit, so that an electric signal can be changed rapidly in a gradual manner.
