HYDRAULIC FEED CHAIN OF SCREW-CUTTING LATHE FOR TURNING TAPERED SURFACES Russian patent published in 1997 - IPC

Abstract RU 2074807 C1

FIELD: machine-tool industry. SUBSTANCE: each hydraulic stepping drive used in the chain of length and lateral feed includes hydraulic stepping motor connected with lead screw of corresponding feed and hydraulic pulse generator. The gear ratio between the length and lateral feed values depends on the ratio of frequencies of the hydraulic pulses sent to the actuating stepping motors and is determined by design number of slots on the rotating sleeves of the hydraulic pulse generators of the length and lateral feed drives. EFFECT: improved feed accuracy. 1 dwg
