Top 3 Screw Thread Manufacturing Techniques in CNC
11 October 2021For parts and products to be held together, manufacturers often maximise screws. Screws feature a threaded shaft so they can be inserted into the parts being connected. Even though nails can already hold items together, screws are much preferred by manufacturers since they can offer more holding power. They could likewise generate a tighter seal and provide more strength.
The functions of screws, however, can only be maximised entirely if they will remain fastened. Screws, fortunately, have threads that can provide enough friction to maintain their fastening act and prevent rampant loosening during their operations. The threads of the screws also help in altering the energy between rotational and linear force and movement. To date, screw threads can be manufactured precisely with the help of computer numerical control (CNC) machining.
CNC machining enables manufacturers to carry out different screw thread manufacturing techniques. Here are 3 screw thread manufacturing techniques that can be done with CNC.
- Tapping
Tapping is a screw thread manufacturing technique that is utilised in creating internal threads. It can effectively cover a lot of screw thread profiles that are needed by various industries. It can even create threaded holes that boast low accuracy of position and small diameter.
Generally, tapping is known for being efficient and cost-saving. It is efficient since the technique involves high-speed cutting without compromising machining efficiency and productivity. The said screw thread manufacturing technique also requires fewer expenses in terms of purchasing cutting tools and other necessary items. It can likewise expect reduced machine downtime. These features of tapping make it cost-saving and economical for those who want to save some resources.
- Thread Milling
Another screw thread manufacturing technique is thread milling. This specific technique works by the circular ramping motion of rotating cutting tools. Thread milling is said to be effective in creating large parts and valuable workpieces. It can also process a host of threads on just one machine.
One great thing about the thread milling technique is that it can maintain high efficiency and high precision throughout the process thanks to durable CNC milling cutting tools. These tools are often made from hard alloys. With these materials, they can easily perform numerous operations without obtaining damages. Thread milling is also known for better cutting finish and results compared to tapping, especially if the workpieces are made from copper, aluminium, or stainless steel.
- Lathe Threading
One more screw thread manufacturing technique is lathe threading. It is a technique that permits various thread pitches, tapered threads, and numerous lead threads without the need to change gears. With the help of CNC lathes, they can effectively generate single point screw threads in one setup of the CNC machined workpiece or product and produce the aforementioned thread qualities.
