Designed for producing stainless steel self-drilling screws and lengthened self-drilling screws. Curved surface desing of the transmission cam prolongs screw pressing time and shortens idle-stroke time, not affecting normal operational cycle during processing, thus achieving excellent motion effects and extending the operating life of the screw die. Self-Drilling Screw Forming Machine(With Index) HRc 60° Precise grinding, rolling friction, low consumption, with beautiful curve and zero-defect. High speed, noiseless, and energy-saving. High precision, original position return, and absolute synchronizing. Simple structure, screw driving, and low rate
