งานรีดเกลียวและงานกลึงเกลียวแตกต่างกันอย่างไร?

What are the differences between thread rolling and thread cutting :

1. Thread Rolling

• 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.
