Dimension Thread Rolling Die Type RS And RSV
The blank diameters for thread rolling quoted here are approximate ,as the properties of material differ. If necessary, the blank diameter should be increased in steps of 0.01mm. Until the thread profile is nearly fully formed. Any further increase in blank diameter overloads and hence damages the tools. Please observe the thread major.
The workpiece must have a 15-20· chamfer to enable the thread rolling dies to start easily both chamfer and blank diameter must run concentrically
