Our Story

FMB Machine

Rhode Island Precision Co., Inc. was founded in October 1972 in Johnston, Rhode Island. It has been located in a sixty-five-thousand square foot plant in Providence, Rhode Island since 1981; and its owner and manager have over forty years of experience in the precision machining field. It has always been the objective of Rhode Island Precision to supply quality components with on-time delivery.

With this in mind, in 1985 the company ventured into the computer-controlled machining field (CNC). We now have some of the most modern and up-to-date CNC machining equipment available. This equipment is capable of producing the precision components required in today’s high level of manufacturing standards.

Quality assurance is our most important concern as the machining industry has advanced to a period of the most stringent standards imaginable. Rhode Island Precision has been able to maintain a high level of quality with the purchase of modern manufacturing and measuring equipment. This coupled with computer-generated SPC programming, advanced in-process and final inspection, and heavy investment in employee training in the new quality technologies has given us the reputation as a quality machining facility. We have and always will strive to be a zero-defect vendor.
