Claims (1)

[Claims for Utility Model Registration] 1. A processing device in which the material is fixed and the cutting tool rotates, the cutting tool having a single or plural cutting blades provided in one direction with respect to the rotating surface, and The relative position of the material and the cutting tool is that when the material surface on the side where the cutting tool is located is the front surface and the opposite surface is the back surface, in a back processing device where the cutting tool processes the back surface of the material, when the cutting tool is facing the back surface and the axis center is When moving the cutting tool in the direction, the cutting tool is stopped in advance, and the cutting tool is moved parallel to the axis by an arbitrarily determined position relative to the position of the cutting tool during machining, and the cutting edge is moved in the direction to minimize movement. is a back processing device characterized by controlling the position of an arbitrarily determined rotational surface in one direction. 2 In the first claim, when the cutting tool has a plurality of cutting edges, the direction of each cutting edge is not necessarily in one strict direction with respect to the rotating surface, but is at least located within one section when the rotating surface is divided into six. A back processing device characterized by comprising a cutting tool adjusted in the direction of. 3 In the first claim, the shape of the cutting tool is composed of a shank part that is directly connected to the power part that generates rotational power and is fixed to the spindle, a guide part that fixes the cutting edge, and a cutting edge part, and the axis of the shank part and the guide part A back processing device characterized in that the axis of the tool is eccentric according to the dimensional relationship that takes into account the rigidity of the entire cutting tool. 4 In the first claim, the control system for moving parallel to the axis of the cutting tool includes a servo control system in order to be able to freely set an arbitrary control range in consideration of the machining dimensions of the workpiece and the shape of the cutting tool. A back processing device characterized by comprising a servo motor cutting tool control device using a motor. 5 In the first claim, as a method for controlling the directional position of the cutting edge, the reference position on the rotating surface of the spindle shown in the third claim is a member that is sensed by a photo sensor, or a member with a predetermined surface treatment. A back processing device characterized in that it includes a photosensor-type rotational position control device that is installed in a portion of the body and detects the position and stops the spindle at that position. 6 In claim 5, the photosensor-type rotation control device uses a motor for rotational power in the spindle, processes the workpiece with the power, and furthermore, the motor also serves as the power for controlling the position of the cutting edge, allowing it to be moved to any desired position. 3° against
A photosensor-type rotation control device characterized by having the ability to stop at an angular position within a certain angle.
