Horizontal Gear Hobbing Machines

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.
