Hilltec Manufacturing utilizes advanced 5-axis CNC gear milling to produce high-precision double helical (herringbone) gears for demanding industrial applications. This process enables the accurate machining of opposing left-hand and right-hand helices on a single gear blank without the need for a center relief groove. By synchronizing multi-axis tool motion with precise rotary control, Hilltec achieves exceptional involute accuracy, lead consistency, and flawless alignment at the gear’s centerline—critical factors for smooth, quiet operation and long service life.

Unlike traditional hobbing or shaping methods that require specialized equipment, Hilltec’s 5-axis milling approach offers superior flexibility and control over gear geometry. This capability allows for the production of complex gear designs, large modules, and custom profiles, as well as efficient handling of prototypes, small production runs, and replacement components. Continuous tool orientation and optimized toolpaths ensure excellent surface finish and dimensional repeatability, even in challenging materials.

With a strong focus on quality and precision, Hilltec Manufacturing delivers double helical gears engineered to reduce axial thrust, increase load capacity, and improve overall drivetrain performance. From heavy industrial gearboxes to power transmission systems operating under extreme conditions, Hilltec’s 5-axis gear milling expertise provides customers with reliable, high-performance solutions built to exact specifications.
