About Thread Cutting Machines
Thread cutting machines generate threads by cutting and removing material to produce a thread shape. Thread cutting is a method of producing screw threads using a single pointed tool to cut into a blank (also called a workpiece) as it rotates on a thread cutting machine. Thread cutting machines are similar to lathes in that they mass produce machine turned parts. Thread cutting machines are, however, highly automated and produce high volume, low costs parts. The screw feed stock (long, cylindrical rods) is fed so that the thread cutting machine automatically turns the feed stock, separates it into individual parts, and advances the rod to create the new part. Thread cutting machines involve more demanding operations than many turning operations because they require higher cutting forces. In addition, the cutting edge of the thread cutting die is smaller and therefore weaker than other types of die.
