As shown in FIG. 1, a main shaft l of a machine tool is held in a main shaft head 2 by a bearing 3, and a drive motor 4 drives a drive shaft 11, a gear 5, a gear 6.
Driven through. Further, a drive shaft 12 of a generator 8 that applies viscous resistance to the main shaft 1 is directly connected to the main shaft 1, and the power generator 1i18 is fixed to a bracket 7 attached to the main shaft head 2. Also, at the output terminal of generator 8 = m

作機械の切削性能を著しく向上させろことができる。When a main shaft 1 of a machine tool is rotated by a drive motor 4, the main shaft 1 drives a generator 8 directly connected thereto. The driven F4 generator 8 generates inductive activation due to the magnitude of the field current, causing current to flow through the resistive load 10 connected to the output terminal. This causes the spindle 1 to move '! The torque required for the A current acts as viscous resistance. The magnitude of this viscous resistance can be easily adjusted by changing the field current of the generator 8 and/or the load resistance. By adding such viscous resistance, the rotation of the main shaft 1 by the drive motor 4 can be made extremely smooth, vibration of the main shaft 1 can be prevented, and the cutting performance of the machine tool can be significantly improved.
