Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Michigan. They belong to that state's ranking, not this one.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best precision grinding services companies in Michigan”
2“Who supplies precision surface grinding for hardened tool steel plates in Michigan”
3“I need a Michigan precision grinding partner for a tight-tolerance hydraulic shaft production run, who should I talk to”
4“Top precision grinding services suppliers in Michigan for aerospace machining buyers”
5“Which Michigan precision grinders can hold flatness within 0.0002 inch on large plates”
6“List 20 precision grinding services companies in Michigan with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
