染による環境悪化の問題を生じさせる。In the field of hobbing machines, various improvements have been made to improve productivity and save labor. In recent years, however, environmental measures have also been strongly desired. An environmental measure in the field of hobbing machines is so-called dry cutting, in which cutting is performed without using a cutting fluid. The cutting fluid not only deteriorates the working environment such as foul odors and fouling due to scattering, but also causes a problem of environmental degradation due to air pollution when processing waste oil.

まう。Problems to be solved by dry cutting have several problems, one of which is
There is a problem that the processing accuracy is reduced due to a rise in the temperature of the workpiece 3 during processing. That is, conventionally, the cutting oil 11 was supplied to remove the processing heat and cool the work 3.
When dry cutting is performed, removal of processing heat and cooling of the work 3 are lost, and the temperature of the work 3 during processing increases.

一になると、歯すじ方向にテーパがついてしまう。For this reason, when the work 3 is processed into a predetermined state in a state where the work 3 is thermally expanded, and the temperature of the work 3 decreases after the work, the work 3 contracts and the accuracy is reduced. Especially,
Since the temperature of the work 3 during the processing gradually increases, the temperature of the work 3 changes from the start of processing to the end of the processing and the amount of thermal expansion changes, and if the temperature of the work 3 decreases after processing and becomes uniform, The taper is formed in the direction of the teeth.
