CNC machining has quickly progressed to the point where it can now replace a variety of conventional tools. Thread mills are an example of a time-saving innovation. Tap and die tools have been used to make threads for decades. Using sophisticated milling cutters, machinists can now thread mill pipe threads in no time. Using full form and single pitch thread mills can assist you in rapidly and efficiently creating threaded surfaces.
Basic tap and die tools or specific machine taps were used to make threads in the past. These instruments progressively “screwed” into or around the threaded component, cutting away material to generate the threads. One major issue was that tapping threads took a long time, especially when working on a small quantity of components by hand. If you were unlucky enough to have a tool break while in use, then you know that extracting the tool without damaging your threaded surface can be next to impossible.
Fortunately, thread mills were developed to address both of these issues. With these end mills, you can thread a component in a matter of seconds. Full form thread mills and single pitch thread mills are the two types of thread mills. Each of these cutting instruments is well-suited to a variety of tasks.
The full form thread mill is the larger of the two alternatives, with the cutting surface created by a row of “teeth.” These tools can thread a component in a single 360-degree pass, making them an excellent choice where time is a concern. Thread milling pipe threads in seconds can make a big difference for many businesses.
To create a spirally threaded surface, full form thread mills cut the threads by completing one rotation while lowering the tool’s height by the thread pitch (the distance between two threads) during the cutting process. As long as the thread pitch is the same, these tools may make a variety of sizes. A full form thread mill will easily do the job as long as you’re working on a steady item with uniform thread pitches.
The single pitch thread mill is the finest alternative for more sensitive work. These cutting tools contain only one “tooth” on the cutting surface, which means that they must cut the entire threaded surface. Although this will take longer, there are some benefits to employing end mills. One of the most significant advantages is that these tools come into less contact with your workpiece, making them suitable for thin-walled or fragile components. They can also be used to make asymmetrical threads and threads with varied pitches. These cutters are a wonderful choice for your shop if you have a complex item with a variety of thread sizes and pitches.
