With over a century of gear manufacturing experience, Gear Motions has amassed an extensive portfolio of gear production capabilities. Whether it’s big or small, cut or ground, there isn’t a precision gear project we can’t handle from start to finish.
Hobbing is a machining process for cutting gear features on both metal and non-metal parts. The gear teeth (or splines) are progressively cut into a cylindrical piece of material by a series of cuts made by a cutting tool called a hob. Hobbing allows you to achieve various gear shapes and sizes such as spur gears, worm gears and bevel gears. Although gear hobbing can be used for prototyping small quantities, this process is best suited for higher volume production.
Our manufacturing partners have various hobbing tools in stock which allow for quick turnaround times. If a custom gear profile is desired that is not part of our standard hobbing tool library, customers can order custom hobbing tools to be built. If you want to create internal gear features, we offer Electrical Discharge Machining (wire and sinker), as internal gear features cannot be achieved with hobbing.
CNC machining can produce a wide array of parts from the simplest component to the most complex assembly. Need to machine a gear shaft for a vehicle? Or an inlet for a heat exchanger shell on a military transport vehicle? What about a precision electrical contact for a fighter jet or a lifesaving pa...
Gear hobbing produces gear teeth by rotating a cylindrically shaped cutter called a “hob” (hence the term gear hobbing) depicted in the gear hobbing machine interface below. The hob can be single-threaded, depending on how many teeth per revolution should be generated.
