Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets on a hobbing machine, which is a special type of milling machine. The teeth or splines of the gear are progressively cut into the material (a flat, cylindrical piece of metal) by a series of cuts made by a cutting tool called a hob. Compared to other gear forming processes it is relatively inexpensive but still quite accurate, thus it is used for a broad range of parts and quantities.
Cutting speeds for carbide hob cutters

Precision solid carbide gear cutting tools

Hobbing is a manufacturing process for gearing and finishing gears. The rotation of the hob cutter generates the actual cutting movement. SCHELL hobs cutters can be used to generate all numbers of teeth, all profile displacements and any angle of inclination.

Gear hobbing is one of the core technologies in gear manufacturing. The quality achieved in this process has a high influence on the following processes such as gear grinding and gear honing.

Gear hobs and gear cutting cutters from SCHELL:

  • Carbide hob cutters for involute tooth shapes
  • Carbide hob cutters for cycloid tooth shapes
  • Carbide thread-milling cutter
  • Carbide tooth profile
  • Carbide setting hobs
  • Konrad hob cutters for frontal gear cutting
  • Shank hob cutter made of carbide
  • Carbide cutters for conical gearing

Carbide hobs permit cutting speeds into the high- speed cutting (HSC) range, and significantly higher than those possible with high- speed steel hobs. The development of suitably rated hobbing machines enables the advantages of carbide hobs to be exploited in practical use.

The carbide gear cutting tools from SCHELL are used on hobbing machines from Liebherr, EMAG, FFG, Gleason-Pfauter, Felsomat, Monnier & Zahner, Oerlikon and others.
