摘要 |
Gear cutting apparatus comprises a hob 9 carried by a radial slide 1 and an axial slide 16, which are moved by independent d.c. motors 20 and 17. A main variable-speed motor 2 on the radial slide 1 is kinematically connected to the hob 9 and to a turntable 10 for the workpiece. The speed of movement of the axial slide is controlled by an electronic circuit which receives signals from dynamo-tachometers kinematically connected respectively to the turntable 10 and to the motor 17 moving the axial slide 16. The movement of the radial slide 1 is controlled in accordance with that of the axial slide 16 by another electronic circuit. |
