Will increase to speed by experienced certified 1000r / min about 2000r / min or more and the silk mill knurled once completed. The process route becomes: cold drawn → knurling, milling silk → correction → drilling, cutting → chamfering. Although the small diameter of the workpiece Whirling larger deformation (deformation of large diameter is smaller), but the correction is easy.

The main performance parameters of a trapezoidal screw to axial load and speed (rpm), that the relationship between the available pressure-velocity (PV) curves. Since the trapezoidal screw sliding surface support the load at runtime, thereby generating frictional heat phenomenon, this process, the sliding surface will wear.
