Metal threading is practically synonymous with metalworking, providing a simple method for shaping and joining two elements together via a helical connection. If this sentence sounds like a load of mumbo jumbo to you, don’t worry. Let’s break down the basics of the metal threading process so you can properly implement it into your future projects.
Elements
Put simply, threads are internal or external grooves on a cylindrical surface. When trying to join or fasten metal parts together, this process provides the screw threads that will create this connection, typically through two types of machines: tapping machines or dying machines.
Tapping machines and dying machines are designed to be highly intuitive provided you take the appropriate safety measures. We can’t overstate how harmful drills designed for metal cutting can be when mishandled, so you must always ensure you employ proper safety training.
Tapping
Tapping is the process for internal threading whereby a pre-drilled hole has grooves cut into it, allowing bolts to be screwed into them. A standard drill can’t get this job done alone, which is why the precision of electric tapping machines is needed. This process is called internal because it takes place inside the hardware.
These machines are adjustable and intuitive, allowing for easy learning and implementation into your workplace and amongst your workforce. If you are curious about electric tapping machines, you can find plenty of advice and services from machinery specialists online.
Tapping machines also come in pneumatic or electric varieties, each with their distinct advantages and disadvantages. You can weigh these up for yourself to decide which option best suits your needs
External
There is no point in drilling the grooves into something if there is no counterpart. External threading, or die threading, is what is used for the bolts and screws needed to finish the fastenings. It is called external threading because the material is external to the hardware.
Once both processes are complete, metals – and woods or plastics – can be fastened or joined together, creating an exceptionally strong link.
