Also named, based in another state

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

Jersey Chrome	Pennsylvania	2 of 15
R&L Tool and Die Co.	Missouri	2 of 15

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