Roberts Precision Machine, Inc. was founded in 1987 with the intent of bringing aerospace manufacturing technologies to the commercial market.  We are a manufacturing team specializing in tight tolerance and demanding feature parts, made from stainless steel, aerospace alloys, and cast materials.  We deliver quality parts at competitive prices with prompt and courteous service.

What makes RPM different:

  • Highest Quality, Guaranteed.  We guarantee 100% quality compliance, first time, every time.
  • 100% on time delivery, Guaranteed.  If we miss a promised delivery date, we will take 5% off your bill.
  • Reserve capacity for rush jobs.  Our standard work days are 10 hours, 4 days a week.  This allows for an extra day every week to accommodate rush jobs.  We have the cure for this common purchasing headache.
  • 100% yield guaranteed.  If you order 100 parts, you get 100 parts, not 99 and a sad story.
