Diameters, Inc. Company Profile

Machinists Herb Illgen and Bob Zarling founded Diameters, Inc., in 1974, to provide southeastern Wisconsin customers with high-quality center-less grinding. Three expansions and over 20 years later, Diameters, Inc., continues that tradition, now with over 30 people in a modern facility completed in 1996.

Our core business includes internal, collet, and between-center grinding as well as inspection services. Yet, our mission remains the same -- creating satisfied customers through quality workmanship, innovative solutions, quick turnaround, and competitive pricing. Customer satisfaction is both our goal and your guarantee.
