If you need threaded parts for your business, there is more than one way to cut threads. Two of the most common thread operation methods are rolling and cutting. There are some major differences between these processes and advantages and disadvantages to consider. Here are some of the good and bad things about cutting and rolling threads.
Rolling
A rolled thread operation is designed for speed. Extruded bolts or blanks get placed into a rolling machine. The process is either manual or automated, and the part enters the machine where it rolls against cutting surfaces which rapidly produce threads.
Rolling Benefits
Rolled threads are a cost-effective way to produce small threaded parts like bolts. You may quickly produce many parts in a very short time. The equipment is durable and long-lasting.
Downside
You can only thread small parts. Also, when you roll threads, it produces threads with smaller body diameters. It is not good for precision threads.
Cutting
A typical cutting process places the part on a lathe type mechanism, and it turns as the cutting edge makes the threads. However, thanks to modern technology, computer numeric control (CNC) makes it possible to create precision threads with a high degree of accuracy and in less time than manual methods.
Cutting Benefits
You get very accurate threads. You can also produce a number of thread types. Also, you may thread very large parts, and this process is often used for custom threads.
Downside
The only downside is cost. This kind of threading operation is slower and costs more than thread rolling. However, if you need large parts and precision threads, it is the best method.
