Koepfer America’s CLC H series of heavy duty horizontal gear hobbing machines offer a competitive and fully customizable solution for high precision CNC horizontal gear hobbing, the company says. The CLC 260-H is rated at 7.874” (200-mm) diameter at 4 DP (mn 6.0). Larger workpieces 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” (3,000 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 workpieces.

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 degrees. For high helix worms or rotors, a special CLC 500-FR-H form milling machine is available.
