The subtractive manufacturing technique known as CNC turning is controlled and programmed by computer numerical control (CNC). As the material is passed into the tool, the machine rotates it to remove any extra material that won't be used to make the finished product.
You might be aware that turning has been around for thousands of years and that 3D printers are now being used to construct machinery. However, the first automated lathes used precisely crafted machine screws! Ball screws used in modern turning centers are much more precise and are operated by motors under computer control (PC or PLC - stands for Programmable Logic Controller, CNC stands for Computerised Numerical Control). This enables us to precisely build your CAD file while also automating the cutting cycle.
By combining a lathe and a mill, a turning center becomes even more adaptable. It has bar stock in a spindle, enabling it to create a screw and thread, as well as milling tools, which enable creation of a hex-head, the creation of slots, or the drilling of holes.
While a turning center combines the best of both worlds, larger pieces are still best suited for a dedicated milling machine. The item can access outside diameter threading and is better suited for a lathe the more cylindrical it is. Still uncertain? If you upload your 3D design, we will provide an estimate for the best lathe and mill as well as a 3D explanation of any trade-offs and threading alternatives.
