New description: [New technical field] The creation is related to the two-axis coaxial machining device, especially the two-axis end of the workpiece rotating by the fourth axis of the central cutting machine Shaft processing unit. [Prior Art] According to the general parts, there are common holes with coaxial holes at both ends to set the bearing, such as the hub of the pedal wheel axle, or a long piercing through the two ends of the part, such as the shaft hole of the bicycle pedal or the ball slider. The return hole for the rolling of the steel ball is processed by the central cutting machine to machine one end of the concave hole or the perforation at one end of the workpiece, and then the workpiece is turned over, and the other end is further processed to be a concave hole coaxial with the previous processing or The previous processing was followed by a perforation. However, for the aforementioned flower hub, bicycle pedal or ball slide, it is a highly precise part, and the axis of the concave hole or the long perforation drilled at both ends must be coaxially high, otherwise it will operate. Not smooth. The step of turning the workpiece is manual operation, and the workpiece is temporarily separated from the clamp when the product is turned over. After the turning, the workpiece is fixed to the fixture again. However, the accuracy of the manual work is poor, and the workpiece after the turning cannot be aligned with the previously processed shaft. The heart position reduces production yield. On the other hand, manually turning the workpiece also increases labor costs. In view of this, how to solve the above problems is the primary problem that the creative office wants to solve. Therefore, after the continuation of hard work and trials, the creators of this case finally have the creation of this creation.
