The housing 10 rotatably supports a spindle 11, and a tool 13 is mounted on the spindle 11 via a collet chuck 12. The end surface A of the spindle 11 on the tool mounting side is provided with a number of tapped holes 14 for balance adjustment, which causes noise during high-speed rotation. Tapped hole 1 in housing 10
A cover 15 is provided to cover the tool mounting side end surface A of the spindle 11 having the spindle 4 so that when the spindle 11 rotates at high speed, noise due to wind noise is not generated.

６が取付けてあり、スピンドル１１が高速回転した時、
風切り音による騒音が起きないようにしている。Referring to FIG. 2, another embodiment of the present invention will be described.
6 is attached and when the spindle 11 rotates at high speed,
Noise from wind noise is prevented.
【００１０】以上説明したような構成としてあるので、
風切り音による騒音が大幅に減少し、スピンドル回転
５００００回転／ｍｉｎ時に９８ｄＢあった騒音が７５
ｄＢ以下となった。Since the configuration is as described above,
The noise due to wind noise is greatly reduced, and the noise of 98 dB at the spindle rotation of 50,000 rpm is reduced to 75
dB or less.
【００１１】[0011]
【発明の効果】当初に掲げたスピンドルの高速回転時の
風切り音による騒音を減少させることができた。The noise caused by the wind noise at the time of the high-speed rotation of the spindle, which was originally proposed, could be reduced.
