題点があった。``Problem to be solved by the invention'' However, it is not possible to suck up all the chips with a dust suction machine, and it is inevitable that fine chips will be scattered around, which may cause scratches on the machined surface. There was a problem. Further, there was a problem in that a large amount of chips adhered to the end face and outer circumference of the dust suction pipe of the dust suction machine, making it easy to pollute the working environment.

屑の処理が行えないという問題点があった。Furthermore, in processing equipment that rotates the workpiece and performs turning processing, it is relatively easy to position the oil mist discharge port and the suction port of the dust suction pipe near the cutting tool; Since the position of the cutting point in the device changes every moment, it is extremely difficult to locate the oil mist discharge port and the suction port of the dust suction pipe near the cutting location. For this reason, there was a problem in that the conventional chip removal means could not adequately dispose of the chips.

成刃先が形成されなくなる。Submerged cutting is performed with the workpiece W immersed in the flow of the cutting fluid. Cutting is performed by cutting with a fly force using a diamond cutting tool (cutting tool 16). Main shaft 1
When cutting is performed by rotation 3, chips generated from the cutting portion 51 are immediately separated from the workpiece W by the flow of cutting fluid and flowed downstream of the processing tank 20. In addition, the nozzle 31
From there, a strong flow of cutting fluid is injected at the tip of the cutting tool 16, which has reached the rotational position just before cutting the workpiece W. The chips attached to the tip of the cutting tool 16 are peeled off by this powerful jet stream. Because chips are pulled off and the temperature rise at the cutting point is low due to submerged cutting, no built-up edge is formed on the cutting tool 16.
