切削能率が怨く多大の工数を要しているのが実情である
。Conventionally, turning of EM steel, which is a cutting material, has been done using a diamond tool because a tool made of ultra-high alloy wears out quickly and cannot be turned. However, even diamond tools
The reality is that it requires a large amount of man-hours and reduces cutting efficiency.

与えることなく、切削部のみを加熱し、加熱部を直ちに
削υ取る加熱切削装置を提供するにある。The present invention focuses on the fact that the machinability of materials that are difficult to cut can be sharply improved if the part in contact with the cutting tool is heated to several hundred degrees before machining. To provide a heating cutting device that irradiates in spots, heats only the cutting part without affecting internal changes in the material, and immediately cuts off the heated part.

ことに上シ、ワークの表面熱処理も可能とするにおる。The main point of the present invention is to keep the laser energy applied to the workpiece constant by moving the machine tool that performs turning with a laser beam, so that the local heating of the workpiece can be kept constant, and the cutting tool and the laser beam are continuously connected to the NIJ machine. Since it moves, the entire surface of the workpiece can be thermally cut under the same conditions, and after turning,
In addition to removing the cutting tool and irradiating the workpiece with only the laser beam, it also enables surface heat treatment of the workpiece.

に凸レンズ27を調整する。8 is a laser generator placed in parallel with the machine body. The laser beam 17 is irradiated upward through the laser guide path 9, is refracted by 90 degrees at the flat surface 18, and is guided through the guide path 10 in the expansion/contraction direction tb.
The laser beam 19 travels straight through the inside of the laser beam 11 . The plane mirror 20 is located within the guide path 1 corner 12 supported by a support base 12g integrated with the table 4a.
It is bent 90' in the direction of 3. The laser beam 13 is transmitted 90' in the T direction by the guide path 14 on the tool rest 5 and the upper plane mirror 22.
The refracted light 23 is further refracted toward the workpiece 7 by a plane mirror 24 in the guide path 14 . convex lens 2
7 condenses the light refracted by the plane mirror 24 and passes it through the tapered guide path 16 so that the laser energy is optimized on the surface of the shake 7. Also, at this time, the cutting tool 5a comes into contact with the workpiece, and the convex lens 27 is adjusted so that it has a dimension that allows cutting.

In addition, since the laser guide path 14.15 is integrated with the cutting tool stand 5, the cutting tool 5a and the laser beam 26 always have a constant dimension. Even when the cutting tool 5a moves, the laser beam moves integrally with the cutting tool 5a, allowing continuous heating cutting. Also, pie) 5
Even when a moves in the Z-axis direction to process the workpiece 7, the guide path of the laser beam 19 is expandable and retractable at 10 degrees 11, so continuous heating cutting is possible even during processing in the Z-axis direction. can.
