When it comes to creating threaded surfaces quickly and precisely, it is hard to beat thread milling. The speed and accuracy of computer numerical control milling machines, combined with the right cutting tools, can take the threading process from taking minutes to only a few seconds. For machinists who want the best possible results with regards to thread milling, solid carbide thread mills are the clear option.
Before we get into the differences between carbide and steel tools, it is important to understand the thread milling process. Specialized end mills are used from producing threads and they typically come in two designs. Full form thread mills are one of the fastest and most efficient options on the market because they can cut an entire threaded surface in seconds. These cutters feature rows of point cutting teeth and are designed to finish an entire threaded surface that is the length of the cutters in one 360 degree pass.
While these tools are extremely efficient, their versatility is limited. Each full form thread mill can only cut threads of a simple pitch size that is determined by the spacing of the cutting teeth along the length of the end mill’s surface. If you want a tool that is slightly more versatile, you need to use a single pitch thread mill. These tools have only a single cutting point, which makes them capable of cutting different thread pitches, though they do take longer due to having to trace the entire threads surface. They can also be used to thread areas on thin walled surfaces and unstable overhangs due to their smaller cutting surface.
Now that you understand a little more about these tools, it’s time to look at their composition. Both of these styles of thread mills are fairly long tools. Length is the enemy of stability when it comes to milling tools, as longer tools tend to oscillate when used at high rotational speeds. This can lead to finished surfaces with a poor finish.
One of the best ways to reduce tool oscillation is to use solid carbide thread mills. While tools made from high speed steel alloys are often a more affordable option, carbide is nearly twice as rigid as steel. This is a result of the fact that carbide tools are made with a combination of This means that when operating at high rotational speeds, carbide thread mills will spin almost perfectly centered instead of wobbling significantly while they spin. This will produce more accurate threads so your components can interlock easily.
