Superior Quality Since 1981

Located in Northeast Ohio

Established in Mentor, Ohio in 1981, specializing in the manufacture and development of prototype components for the aerospace industry, Tessa Precision gained a reputation for creativity and innovation. We designed processes to generate high-quality precision components.

The business moved to the 25,000 sq. ft. Painesville, Ohio site in 2000 and expanded the facility to 45,000 sq. Ft. in 2015. We provide a wide range of precision CNC turning, milling, grinding, and EDM machines. Additional capabilities include electrolytic grinding, flow testing, and assembly.

We employ precise manufacturing control plans that start from receipt of raw material through part production, final packaging, and shipment. We utilize SPC, Gage R&R, and Lean Manufacturing principals to maintain quality and continuously improve. With almost forty years of experience, Tessa Precision has grown to be one of the leading precision aerospace manufacturers in north-east Ohio.
