CNC Gear Machining: Hobbing, Grinding and Inspection
CNC gear machining combines controlled cutting, heat treatment, finishing and inspection to produce gears with the geometry and surface quality required for industrial power transmission. At KNGEAR, CNC machining supports custom spur, helical and other precision gear components for new gearbox projects and replacement work.
Gear Hobbing for Tooth Generation
Hobbing is widely used to generate external gear teeth before heat treatment. CNC control helps maintain repeatable tooth geometry across production batches and allows different modules, pressure angles and helix configurations to be produced from engineering data.
Precision Gear Grinding After Heat Treatment
For hardened gears, grinding is used to finish the tooth flanks after carburizing or other heat treatment. This process improves tooth profile accuracy, surface finish and contact behavior, which can reduce vibration and improve load distribution in demanding gearbox applications.
CNC Machining of Shafts and Gearbox Components
Gear quality also depends on the accuracy of shafts, bores, shoulders, keyways and mounting interfaces. CNC turning, milling and boring are used to control these features so that gears and bearings remain correctly aligned during assembly.
Inspection and Quality Verification
Dimensional inspection, gear measurement and contact checks are used to verify that machined components conform to drawings and fit the intended gearbox assembly. For replacement projects, inspection is especially important because the new components must match existing interfaces and operating geometry.
Custom and Reverse-Engineered Gear Production
CNC gear machining is particularly useful for engineered-to-order parts, obsolete gear replacements and low-volume industrial applications. Drawings, samples or dimensional data can be used as the starting point for manufacturing review and process planning.
