A family-owned business for over 50 years, Grace Engineering is a producer of precision machined medical devices of various shapes, sizes, materials and volumes.

We pride ourselves on thinking and processing parts outside the box to provide solutions to customers.

We specialize in CNC Swiss Screw machining and subsequent grinding processes, as may be required.  Many other manufacturing processes are also utilized to support production as are required.  Using these technologies, we are able to consistently and accurately produce parts to customer specifications, including complex part geometries, small/precise diameters (down to 0.039in diameter with a .0003in tolerance), and varying part lengths from ½in to 12in.
