The electronic gearbox is the defining technology that separates modern CNC hobbing machines from the mechanical hobbing machines they replaced. On an older machine, the precise speed ratio between the hob and workpiece — the ratio that determines the number of teeth...

Large-module CNC hobbing — module M6 and above — is a fundamentally different engineering challenge from the fine-pitch automotive gear production that dominates discussion of hobbing machine technology. The cutting forces at M14 are orders of magnitude higher than at...

Automotive transmission gear production is the highest-volume, highest-consistency application in the CNC hobbing industry. A single passenger car gearbox contains 20 to 40 individual gears, an EV reduction unit contains 4 to 8, and production volumes for a single...

The choice between a direct-drive and a gear-driven spindle system is the single most consequential design decision in a CNC hobbing machine — more consequential than the brand of CNC control, more consequential than the number of axes, and arguably more consequential...

CNC hobbing machine selection is often led by the wrong criteria — headline price, maximum spindle speed, or the brand name of the CNC control — rather than the specification parameters that actually determine whether the machine produces your gears at the required...
