Some things to consider when sourcing a CNC Machine Shop

It can be a frustrating experience to source a good, high quality, reliable, and “cost effective” CNC Machine Shop.  While there are many shops that may be qualified in your geographical area, how do you eliminate the ones that aren’t going to meet your requirements?.

I have thought about some of the things I have learned during 30 years in the machining world acting as a machine shop buyer and as a vendor.  The following are some ideas that I hope will be helpful.

The first and most important thing you need to do is to establish your own benchmarks:

By this I mean you have to know exactly what you want in a finished product.    If you are unsure about this step, many machine shops will gladly help you with establishing desirable characteristics in the finished product.

Also, there are accepted industry standards such as ASME, SAE, and ANSI (I am not going to go deeply into these standards since this information is easily available to anyone who has an internet connection).   Wikipedia says “A Standard can be defined as a set of technical definitions and guidelines that function as instructions for designers, manufacturers, operators, or users of equipment”.

By applying standards you are saying what you expect in a finished part or assembly.

What is your idea of quality?

How do you define quality for your organization?  Is tolerance and adherence to size important?  Is finish and appearance critical?  Is material type vital?  Maybe these items have more or less importance on different part numbers in your organization.  Maybe there are combinations of determining factors

How do you ensure that the machine shop you pick is going to be on the same page as you when it comes to all these variables?
