Gears are manufactured using a technology called hobbing, which is why gear-cutting machines are referred to as hobbing machines. EMAG has two types of gear hobbing machines in its product range: horizontal hobbing machines that only perform hobbing operations, i.e. produce all types of pinions, gears (gearwheels) and worm gears.
There are also vertical hobbing machines that are used for combined machining (see combined turning/hobbing technology) to produce gears for chucked components. The vertical design allows for a variety of automation options that are ideal for mass production when combined with the machine’s small footprint. Hobbing machines from EMAG Richardon are perfect for gear hobbing and machining of large components up to module 12.
Covering a unique spectrum of production applications, the HLC 150 H stands out because of the number of innovations included.
This machine’s ability to hob either straight, angled, or worm gear profiles on a wide range of geometries (short gears or long shafts with gear profiles), puts all of EMAG KOEPFER’s expertise at the user’s disposal. To compliment this machine’s abilities, a device for chamfering and deburring of components during loading and unloading, without interrupting operation is also included. Together, these features allow for the perfect gear-cutting solution with short cycle times and minimized costs.
The horizontal hobbing machines of the K series combine the latest technology with the highest universality and flexibility. All imaginable gear-cutting applications can be solved with these gear-cutting machines. The machine’s spectrum of production applications includes both wheel-shaped and shaft-shaped workpieces. A variety of automation processes are also available and allow for larger production volumes.
The VL 4 H/VLC 200 H gear hobbing machines from EMAG Koepfer feature high-performance drives that enable high speeds and torques on the working spindle and hob. They ensure productive manufacturing of gears with a maximum diameter of 200 mm (8 in) and module 4 by means of dry hobbing within short machining times.
The gear hobbing machines from EMAG Richardon offer long travel paths, large machining areas and a wide range of speeds and performance capabilities. Additional processes such as deburring, cleaning, brushing, drilling, and re-turning can be integrated as required by the application, making it possible to machine a wide variety of parts!
A variety of machine sizes—from R 200 to R 300, R 400 and R 500—are available for workpiece with diameters between 10 and 700 millimeters (0.4 and 28 in) and module sizes 1 to 12.
