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