Process : Thread rolling involves pressing the metal to form threads using rollers or dies. No material is removed in this process; instead, pressure is applied to deform the metal and shape the threads.
Characteristics of the Workpiece : The threads produced are stronger since no material is cut away, preserving the metal’s internal structure. The surface of the threads is also more durable.
Advantages : Rolled threads are stronger, the production process is faster, and there is less material waste.
Disadvantages : Thread rolling requires more complex tools and processes and is not suitable for producing small or intricate threads.
2. Thread Cutting
Process : Thread cutting involves removing material to form threads, typically using a lathe or CNC machine with a cutting tool that carves out the desired thread shape.
Characteristics of the Workpiece : Thread cutting allows for more precision and is better suited for creating detailed or customized thread designs.
Advantages : It is ideal for producing complex or small threads and is well-suited for low-volume production or tasks requiring high precision.
Disadvantages : Cut threads are generally weaker because part of the material is removed, compromising the structural integrity of the metal.
Summary of Differences
Thread rolling does not remove material but uses pressure to form threads, resulting in stronger threads.
Thread cutting removes material to create threads, making it suitable for detailed and precise threads, though the resulting threads are generally less strong than rolled threads.
