About Us

J&J Machine manufactures high-quality, American-made products, on time, at a fair price.  We conduct business ethically and provide superior customer service.

We machine precision components from metal, plastics, and other materials.  Our core capabilities include programming, CNC turning, CNC milling, grinding, laser engraving and 3D printing, and assembly.  Our network of suppliers provides sheet metal fabrication, plating, painting, welding, and other related specialties.

We perform prototyping and small-lot production.  We primarily focus on the needs of customers in the medical, aerospace, and scientific sectors, but we have a diverse customer base in other industries including R&D, optics, photonics, microwave communications, battery technologies, metrology, and semiconductor manufacturing.

We employ a small team of highly capable machinists and managers that enjoy a challenge and work hard to meet the demanding requirements of our customers.
