Threading a shaft using a die

 

 

 

Threading dies are used to cut screw threads on the external surface of cylindrical shafts. Different dies are available for different diameters and thread profiles.

The shaft to be threaded is bevelled to facilitate easy entry of the die. The rod is clamped in between the jaws of the vice while the die is mounted onto the die stock holder. The die is held firmly by means of adjustment screws pushing against its recesses. The slit in the die allows the adjustment of its diametre by tightening or loosening the middle screw. Once everything is in order rotate the die onto the shaft. It is a good practice to rotate the die a quarter turn back after every half a turn onto the material. This prevents the die from clogging by breaking and removing the chips thus ensuring cleaner threads and longer die life.
