METAL SPINNING OF AXIALLY SYMMETRIC PARTS USING PROPORTIONAL ELECTRO-HYDRAULIC DRIVE WITH TRACKING SYSTEM
The paper discusses methods and machine equipment for metal spinning process. It is proposed to apply for performing of metal spinning process electro-hydraulic drive with a tracking system that allows to produce parts by different machines such as turning, milling including CNC machines. The design scheme and a mathematical model of the electro-hydraulic drive are developed. Comparative researches of electro-hydraulic drive work with a tracking system and without it are carried out.
