ZP28-65 modelRailway Spike Thread Rollling Machine can also be used for railway spike making . The thread rolling machine can roll the thread of the steel pipe and steel bar, twill and straight lines of the workpiece in the cold environment; the helical gear and spline gear can be rolled to straighten, calender, shrink and various forming rolling within the rolling pressure range. The machine tool has safe and reliable electro-hydraulic execution and control function, which can make each working cycle choose among manual, semi-automatic and full-automatic modes.
Cold rolling process is an advanced non cutting process, which can effectively improve the surface finish, hardness and strength of the workpiece. The effect is several times or even dozens of times higher than that of cutting. It is an ideal high-efficiency energy-saving process and an ideal choice for energy saving. Its application is more and more favored by users.
