Driving system for automatic lathes |
摘要 |
An electric motor can drive a workpiece and a tool simultaneously at speeds in a ratio adjustable at will. The workpiece is driven via two pulleys and a belt, while the tool is driven via further pulleys and a belt from a hydraulic circuit comprising a pump coupled to the electric motor and a hydraulic motor. The pump is preferably of the variable-capacity type so that its flow can be modified independently of the speed of the electric motor.
