Choosing a CNC Engraving Tool

A CNC machine allows technicians to completely automate machine tools to run in a pre-programmed and highly detailed pattern. First, the technician designs the part, component or product in a computer aided drafting software, and feeds the digital file into the CNC machine. The machine then overlays the pattern on whatever medium is being cut, drilled, welded, or engraved. If you are looking for a tool to allow high quality engraving with minute detail, a CNC torch may be the perfect solution. Here are a few guidelines for choosing the right tool for your job, equipment, and medium.

Choosing the Right Tool for the Job

Depending on what type of engraving you need done, it is important to select the right tool. If you are carving or engraving a word or pattern with a lot of detail, you may want to use a router bit with a small angled tip, or a torch with a very thin bladed flame. For large text or design engravings a cutting torch with large degree will do the job best. Try to keep the tool you will use in mind when you are designing the tool path the CNC machine will follow to produce your design. 

 Choose the Right Tool for Your Equipment

Specifically, this means choosing the tool that is most compatible with your spindle motor. You will not use the same cutting or engraving tool on a low power motor as you will a motor with a lot of power. For smaller motors focus on reducing resistance to the cutting tool rather than increasing speed.

Choose the Right Tool for the Medium

You can use a CNC torch to cut, carve, or engrave nearly any medium, however you may need a specific torch tool for each one. For instance, plastic is much safter than a sheet of iron, and will require a tool that is much more delicate. Be sure to read your CNC tables user manual and always make sure that it is set up properly for the material you are cutting or carving.
