Precision Ground Gears
Precision-ground gears facilitate quieter running and higher loads than finish-cut gears. Northern Tool & Gear, with extensive experience in gear manufacturing, provide a cost-effective, high-quality service for precision-ground gears from 50mm pcd to 1200mm pcd. Our gears are manufactured on the latest CNC threaded wheel and form grinders, backed up with on-site heat treatment and CNC gear inspection facilities. We utilise advanced technology to manufacture precision gears, ensuring high standards of quality and functionality.
Quality Assurance
At NT Gear, quality assurance is a top priority. We are proud to hold certifications such as ISO 9001 and AGMA, which underscore our commitment to delivering high-quality products. Our rigorous quality control measures include 100% inspection of all gears to ensure they meet the exacting standards required by our clients. Additionally, we implement comprehensive testing protocols to verify the performance and durability of each gear, ensuring that our precision-ground gears consistently exceed industry expectations.
Benefits of Precision Ground Gears from NT Gear
Precision-ground gears from NT Gear offer multiple advantages that make them an ideal choice for various applications. Here are some of the key benefits:
Superior Accuracy
Precision-ground gears are manufactured with exceptional accuracy, ensuring that each gear fits perfectly into its designated application. This level of precision is crucial for maintaining the efficiency and reliability of machinery, reducing wear and tear on the components, and enhancing the overall performance of the equipment.
Extended Lifespan
One of the standout benefits of precision-ground gears is their extended lifespan. The meticulous manufacturing process ensures that these gears are durable and robust, capable of withstanding high loads and demanding conditions. This longevity translates into reduced maintenance costs and less frequent replacements, providing significant cost savings over time.
Noise Reduction
Noise reduction is another critical advantage of precision ground gears. The smooth and precise surface finish achieved during the grinding process minimises friction between gear teeth, resulting in quieter operation. This is particularly beneficial in environments where noise levels need to be controlled, contributing to a more comfortable and productive workspace.
Precision-ground gears from NT Gear deliver superior accuracy, extended lifespan, and noise reduction, making them a valuable investment for any industry seeking high-quality gear solutions.
Frequently Asked Questions
Grinding delivers tighter tolerances, superior surface finish, lower noise, and higher load capacity—ideal for high-duty, high-accuracy applications.
We grind gears from 50 mm to 1200 mm PCD on CNC threaded-wheel and form grinders, with in-house heat treatment and full CNC inspection.
Common options include alloy and case-hardening steels, stainless grades (application-dependent), with carburising, induction hardening, nitriding, and tempering to achieve the required hardness and case depth.
We manufacture to customer-specified AGMA/ISO/DIN gear quality classes, controlling profile, lead, pitch, and runout on CNC inspection equipment. Target tolerances are agreed per application and drawing.
NT Gear is ISO 9001 certified and manufactures to AGMA/ISO/DIN gear standards as specified on the order or drawing. Test and inspection reports are available with each batch.
