How does material selection affect the process

Material selection is another key consideration in CNC machining services. For example, we might look at a drawing and initially think it's a nice part of the machine, but on closer inspection, we might find that engineers want to make parts out of tungsten -- a material that not everyone can process very well.

Even for metal cutting, it can be very challenging to finish the part exactly the way the customer wants it to if using a CNC milling machine, CNC lathe or Swiss-style CNC screw specified drawings, making tungsten parts more likely to be ground than machined.

In another example, an engineer might specify a small tube made from a sturdy piece of 304 stainless steel -- a very popular material known for its corrosion resistance and other beneficial properties. However, SS304 is very tough and burrs do not come off easily, so it may not be the best choice for very small tubes that require a burr-free finish.
