Abstract: As the most productive knitting machine, warp knitting machine has become one focus of the national "NC generation" mechanical product innovation project. This paper gives a detailed description of the high-speed data-bus, electronic gear, electronic cam, piezoelectric ceramic fast driving, which are the key technologies used in modern warp knitting machine CNC system. It also analyses the present situation and developing trend of warp knitting machine numerical control system systematically.

Key words: warp knitting machine; numerical control system; high-speed warp knitting machine; electronic gear; ECAM; piezoelectric ceramics
