HMC has produced precision gearing and components for many years for various defense contractors and directly for the government. Throughout our history, we have manufactured many ITAR regulated components for our Military and Defense Contractors ITAR Controlled Projects. We also provide support for Federal and State Infrastructure for the Army Corp of Engineers State DOT’s and General Contractors.



This is an image of a XXXXXX XX-X-XXXXXX-XXXX that we recently manufactured completely in-house for X-X-XX-XXXXXX-XXXXXXXX. This will be used in the main drivetrain for XX-X-XXXXXX-XXXXXX-XXXXXXXXXX. This gear was ground on our 6 meter Höfler gear grinder. This gear had XX-X teeth, a XX-X diametral pitch, XX deg. pressure angle and a XX-X face. Our technologically advanced and modern gear cutting, grinding, machining and inspection equipment, are all capable of producing and verifying tolerances from AGMA 8 to AGMA 15, in any tooth configuration including Spur Gears, Helical Gears, Double Helical Gears (or Herringbone) on diameters up to 315 inches.
