History of R&H Machine Products

A History of Precision Machining

R&H Machine Products specializes in precision machining and was established in 1967 by Ralph Rassi & Bob Hayes. It began as a small family-run screw machine facility based in Marcellus, Michigan. Denny Grice purchased R&H Machine Products in September 1995, and moved the company to its current location in Three Rivers, Michigan.

This move allowed R&H to triple its manufacturing space, allowing steady growth. Since then, R&H has diversified its production with sophisticated CNC machining tools and continued to add to its production capabilities.

Another Expansion

In 2013, once again pushing the limit of its capacity in both machine tools and space, R&H added an 11,200-square foot addition to its existing Three Rivers location, as well as bringing additional advanced precision machining equipment online.

The addition doubled the company’s physical size, and brought the company up to 20,500 square feet. The expansion will allow R&H room to grow and provide the best in precision machining for years to come.

The Way We Work

Even though a little part may only cost 10¢, the actual cost can be millions if it fails to operate properly and causes the entire line to go down. That’s why R&H is the precision machining company where  “Every little thing matters” isn’t just a slogan, it’s the way we approach everything we do.

From the way our custom parts are designed and engineered, to the way they’re precision machined, to the way they’re packaged, delivered and inventoried, no detail is too small. No opportunity to improve is overlooked — whether it’s providing better finishes, tighter tolerances or better delivery.

Some people have even accused us of being obsessed with detail. We wouldn’t have it any other way.

Not just talk

At our precision machining company, we don’t just talk about “Every little thing matters.” We walk the walk. When a customer requested a tolerance to be cut in half, we made it four times tighter. To provide the best machined parts possible, we hand-inspect them, and if needed, de-rust and de-burr them at our cost. We’ve even been known to load parts in our cars and personally deliver them overnight to keep a plant running smoothly.

Of course, we don’t need to take those drastic measures very often. We’ve developed systems and processes based on actual data that enable us to keep track of performance and eliminate most potential problems long before they arise.
