Expert Gear Grinding Services in New York

Gear grinding is a precision finishing process that removes material from gear teeth using an abrasive grinding wheel to achieve superior surface finish, exact tooth geometry, and tight tolerances. It's essential for heat-treated gears requiring AGMA Class 13 precision, producing the smooth, quiet operation demanded by aerospace, defense, and medical applications.

Gears require grinding when heat treatment causes distortion, when applications demand AGMA Class 13 precision beyond what cutting achieves, or when specific profile modifications, lead corrections, or tip relief adjustments are needed. Grinding also salvages out-of-spec gears and provides the superior surface finish required for high-performance, low-noise applications.

We grind external gears up to 400mm (approximately 15.75 inches) in diameter. Our capabilities include spur gears, helical gears with helix angles up to ±45 degrees, and geared shafts. We achieve AGMA Class 13 precision on heat-treated components and can perform custom profile, lead, and tip relief modifications.

We achieve AGMA Class 10 on non-heat-treated gears and AGMA Class 13 on heat-treated gears through our advanced profile grinding capabilities. AGMA Class 13 represents the highest precision standard, essential for aerospace, defense, medical, and other critical applications requiring exact tolerances and superior performance.

Yes, we specialize in custom profile modifications, lead corrections, and tip relief adjustments according to your specifications. We provide detailed Gear Charts that validate all modifications, ensuring your gears meet exact performance requirements. This capability is crucial for optimizing gear performance in specific applications.

Yes, we perform in-house nital-etch testing to detect grinding burns and validate surface integrity. This quality assurance step ensures every ground gear meets specified standards without metallurgical damage that could compromise performance or service life.

Absolutely. We specialize in salvaging gears that have gone out of specification due to heat treat distortion. Using our precision grinding capabilities and expertise, we can restore these gears to exact tolerances, saving you the time and expense of manufacturing replacement gears.

Turnaround time depends on gear size, complexity, quantity, and current production schedule. Our comprehensive in-house capabilities allow us to maintain control over timelines and deliver efficiently. Contact us with your specific requirements for an accurate time estimate tailored to your project.
