Gear Cutting Processes - the fine Art for Precision-fit Connections and maximum Power Transmission  

Gear hobbing is a highly productive milling process to produce gear teeth, primarily for gears, which are produced by hobbing a special gear hobbing tool on the workpiece. We can integrate gear hobbing on our horizontal as well as on our vertical production and turning-hobbing centers, and thus produce almost any number of teeth and helix angles for a wide range of workpiece sizes. This allows us to produce all common gears on your component, such as external spur and helical gears, bevel gears, or helical gears, in a process-integrated manner, thus providing low non-productive times and cost-efficient production of your component. In addition, our in-house technology interface "GearHobbing aUI" allows for the creation of machining programs automatically without extensive prior knowledge in NC programming.

 

Hob peeling, also known as power skiving, is a high-performance gear cutting process used for high production manufacturing of internal and external gears – particularly splines, helical gears, and spur gears. The process, in which the workpiece and tool axes must always be at a specific angle to each other, is characterized by its extremely high productivity and high cutting speeds compared to shaping or conventional gear hobbing. By integrating this process into our vertical and horizontal machining and production centers, complex components with gear teeth are machined economically up to gear tooth class 7 in a single clamping operation. In addition, our in-house technology interface "GearSkiving aUI" can create machining programs automatically without extensive prior knowledge in NC programming.

Roller shaping, a sub-process of gear shaping, is a versatile combined process of generating and shaping motion for the production of any internal, external, or special gears. Since it is a highly specialized process, it is often used for smaller batch sizes or unique workpieces for which, due to geometry and collision, gear hobbing or gear shaping is not suitable. However, due to the flexible configuration of our machining and production centers, the process can be integrated into other main processes so that even complicated components can be machined without interruption.

Gear shaping, often referred to simply as shaping, is a flexible machining process based on straight-line shaping movements with a specific cutting edge to produce straight internal, external, and special gears as well as grooves. The process is mapped either by using driven special shaping tools or by lateral movement of the tool aggregate used. A distinction is made between the use of shaper wheels or single shaper tools.

Invomilling is a new, manufacturer-patented gear cutting process which is particularly suitable for the extremely flexible production of external gears and keyed gears. With this process, it is possible to produce a wide variety of gear profiles with only one standardized tool set. As a rule, side milling cutters are used which reproduce both roughing and finishing processes. It is therefore more suitable for small and medium series, but is extremely productive and economical in this field. It should be emphasized that this process can also be used to easily produce gears with a very large module.
