CNC Machining is the process of designing a part using computer aided design (CAD) software which then uses milling or cutting tools to produce the part. You're looking for a reputable custom CNC machine shop supplier that can supply you with custom machined parts with precision
The most important thing to consider when choosing a custom CNC machine shop supplier is the quality of their machined parts. This is crucial because if you're trying to build any complex mechanical objects, it's going to be made up of multiple different components which will need to be assembled together
It's also important to check out their reputation and track record, as some shops may only have one or two projects under their belt while others may have many more years under their belt. The best way to get an idea of who they are and what they've done in the past is by looking at other customers' feedback, although you can also ask them directly at any point during your conversation with them so that they can tell you exactly what they've done in the past and what kind of work they have coming up in the future.
