Live Tooling vs Atẹle milling on Swiss Lathes

Ohun-elo Live vs Milling Secondary lori Awọn Lathes Swiss: Ti o dara ju Titan Ipese CNC

PFT, Shenzhen

Áljẹbrà: Swiss-Iru lathes se aseyori eka apa geometries lilo boya ifiwe tooling (ese yiyi irinṣẹ) tabi Atẹle milling (post-titan milling mosi). Itupalẹ yii ṣe afiwe awọn akoko iyipo, deede, ati awọn idiyele iṣẹ ṣiṣe laarin awọn ọna mejeeji ti o da lori awọn idanwo ẹrọ iṣakoso. Awọn abajade tọkasi ohun elo ohun elo laaye dinku akoko iwọn apapọ nipasẹ 27% ati ilọsiwaju ifarada ipo nipasẹ 15% fun awọn ẹya bii awọn iho-agbelebu ati awọn ile adagbe, botilẹjẹpe idoko-owo irinṣẹ akọkọ jẹ 40% ga julọ.
