Fictiv’s manufacturing network includes a range of gear hobbing machines, including:
Mazak i400AG Hamai N60 Kitamura-3X Vertical CNC
Units: mm 0.06, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.7, 0.75, 0.8, 0.9, 1, 1.25 and 1.5.
We accept the following gear hobbing standards:
Customers can minimize cost and lead time by selecting a standard hobbing tool. Building a custom hobbing tool requires longer lead times, greater hobbing tool cost and time for pre-production testing. For custom tools, customers must submit a drawing in addition to a 3D model to specify the gear hobbing tool (module), number of teeth, and level of precision required.
Worm gears are made using a combination of hobbing and milling. Bevel gears are made using a combination of 5-axis CNC and hobbing.
For standard gears, please submit a 2D drawing with your model that specifies the following information: module, number of teeth, and the precision level.
For spur gears, please submit a 2D drawing with your model that specifies the following information: module, number of teeth, pressure angle/helical angle, and the precision level.
For profile shifted gears, please submit a 2D drawing with your model that specifies the following information: profile shift coefficient, tooth to tooth composite error, and tooth profile tolerance.
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.
