Spiroid quality control engineer testing high torque gear


Spiroid’s operational philosophy has always been to ‘focus on the core’ and lean on strong vendor partnerships to manage outside processing of parts. For Spiroid, the ‘core’ is subject matter expertise, application engineering, and specialized metal removal. Put another way, Spiroid’s value is in its ability to design the right cutting tool that can be used to manufacture the best, most appropriate gear set for a given application.

When it comes to heat treatments and specialized finishes, Spiroid relies on a Rolodex of long-standing partners to execute in their respective areas of expertise. For a list of equipment that Spiroid utilizes, please see our “Equipment & Capabilities” brochure.
