The YINGYEE Automatic Screw Rolling Machine (Model Z28-80) is a high-precision cold rolling solution engineered for industrial-grade thread production. This robust machine is designed to handle a wide array of thread types, including common, tilted, straight, acme, and module threads, ensuring superior straightness and a high-polish finish for every component. By utilizing a sophisticated cold rolling process, it achieves exceptional diameter reduction and structural integrity without the material waste associated with cutting.
Equipped with a flexible electric and hydraulic executing control mechanism, the Z28-80 offers seamless transitions between manual and automatic operation modes. It is specifically optimized for carbon steel, alloy steel, and non-ferrous metals with hardness levels below HRC 37, making it an indispensable asset for manufacturers requiring high-strength fasteners and precision-rolled parts with tight tolerances and consistent quality.
