を要するためにコスト高になり却て不利益である。B. Prior Art Conventional numerically controlled lathes employ a computer-based numerical control system, but loading and unloading materials on the lathe is done manually, which is inefficient. In addition, there are cases in which robots are used to attach and remove materials, but this requires a large amount of investment, resulting in high costs and is rather disadvantageous.

This system streamlines the cooperative operation of the two systems. The headstock mechanism consists of a vertical headstock and a spindle, and the function of the spindle is to grip the material at its tip.
As a function for this purpose, movement in the direction of the spindle is performed by vertical movement of the headstock, and the spindle can also be rotated.

切削加工をすることが可能となった。The feature of this headstock mechanism is that it is vertical, so it requires less floor space, and the work indexing wheel mechanism is a horizontal rotary circular table that allows material to be fed in place of the traditional manual or robotic material feeding method. Materials can be placed at regular intervals around the periphery of the headstock and rotated as appropriate, as well as reciprocated toward the center line of the spindle of the headstock. With this configuration, when the material placed on the table and the headstock spindle are in the same position, the spindle can grip the material with high precision.This, combined with the highly accurate operation of the tool post mechanism, results in high efficiency, high precision, and labor saving. It is now possible to perform cutting operations.

値制御式旋盤。It consists of a vertical headstock mechanism with two main spindles, a work index table mechanism, two tool post mechanisms that move up and down, and a numerical control mechanism that operates in conjunction with this, and grips the material at the lower end of each spindle. A mechanism is provided, and in the work index table mechanism, of the material trays provided at equal intervals around the entire periphery of a circular table that can be indexed and rotated, two trays facing the two main shafts are connected to the corresponding main shafts. The tool rest mechanism is configured such that the two tool rests can be horizontally reciprocated toward the center line of the machine, and material feeding operation can be performed at the point where the center line coincides with the center of each of the material receiving trays. It can be horizontally reciprocated toward the center line of the corresponding spindle, and can be moved up and down along the center line of the spindle, and each tool post is equipped with not only a fixed tool but also a rotary tool to enable compound machining. A double-head vertical numerically controlled lathe with a work index table, characterized in that the two sets of main spindles and tool rests can perform the same or different operations depending on a control mechanism.
