CNC lathes require the right tooling for internal threading, dependent on the type of material in use. Soft metals such as aluminum can be effectively worked using carbide tooling but harder metals like stainless steel benefit from high-speed steel (HSS) tooling. As a result, selecting the correct equipment should be considered with great care.
When it comes to the pitch of the thread you’re cutting, the rule of thumb is that the coarser the thread, the less tooling is needed to handle it. To illustrate, a single cutting tool can get through a coarse metric thread; for fine metric threading, however, it’s recommended to use three equally-sized tools.
Thread depth plays a major role in determining the task at hand. Less pronounced threads can be taken care of with one instrument, but greater depths call for multiple instruments.
It is critical to keep in mind the kind of CNC lathe you are working with. Some lathes are obviously intended to be utilized with a specific set of tools, while others offer more flexibility. To illustrate, some lathes cannot accept carbide tools, yet other can only take HSS tools.
When selecting tooling for a CNC lathe to create internal threads, the type of material is the key consideration. For softer metals, for instance aluminum, carbide tools are the best fit; however, with harder metals, such as stainless steel, high-speed steel (HSS) tooling is necessary.
When deciding what thread to use, take the pitch into account – it will make a difference in terms of tooling needed. For example, if you opt for a coarse metric thread, you only need one tool, whereas a fine metric thread demands three different tools in order to be cut.
Engaging multiple tools may be necessary to craft deeper threads. However, shallower threads can be produced with only one tool. The depth of the thread is a key detail to keep in mind.
It’s essential to factor in the type of CNC lathe when you make a choice. Certain lathes can accommodate only specific kinds of tooling, while others offer more versatility. For example, some only work with high-speed steel (HSS) tooling, and others won’t support carbide tooling.
