Koepfer Introduces New 'H' Series Hobbing Machines

November 10, 2014
Koepfer America, L.L.C., introduces the CLC “H” series of heavy duty horizontal gear hobbing machines to the North American gear manufacturing market. These machines offer a competitive and fully customizable solution for high-precision, CNC horizontal gear hobbing.

The CLC 260-H is rated at 7.874” (200 mm) diameter at 4 DP (mn 6.0). Larger work pieces can be hobbed with a maximum swing of 20.472” (520 mm) diameter. The larger CLC 500-H is rated at 19.685” (500 mm) diameter at 0.847 DP (mn 30.0) with a maximum swing diameter of 31.496” (800 mm).

Both machines can be built with different bed lengths to provide axial travel up to 118” (3000 mm), making either machine a flexible solution for shafts and pinions. Additionally, these machines have unique features, such as a large through-hole in the work spindle for extra-long work pieces.

These machines also have standard features such as high-speed direct-drive torque motors for both the work and cutter spindles, Fanuc 31i numeric control, and optional skiving (carbide re-hobbing) capability with an integrated electronic timing probe. They are also equipped with a high-speed hob head that swivels ±45°. For high-helix worms or rotors, a special CLC 500-FR-H form milling machine is available.

The CLC “H” series provides North American gear manufacturers a new, yet proven, option for horizontal gear hobbing. Finally, these machines can be specially customized as needed to provide customers an optimal solution for their gear manufacturing needs.
