*Depends on the gearing norm / Other modules upon request

Gear cutting is a very high precision operation. It can be performed in multiple ways. The best
one is the most efficient in terms of time and cost, depending on :

  • The quantity of pieces to be cut
  • The type of pieces
  • The shape of the tooth profile
  • The machine
  • The habits and the know-how

For many years, Louis Bélet manufactures all kinds of gear cutting hobs. All have been tested and
approved by our reference customers to their whole satisfation.

Z² - Tooth by tooth gear cutters

1 Colonne Z2

Easy to set up, Perfect shape

Tooth by tooth gear cutting is a simple process, fast and economical for prototyping and small scale productions. This process allows cutting of all types of toothing, including deep teeth and asymmetrical profiles. Louis Bélet produces tooth by tooth gear cutters as circular mills or T-slot end mills, the dimensions beeing customized according to customer’s needs. A perfect profile is guaranteed on the tool.

ORIGIN - Hobs for epicyclic and Involute teeth

1 Colonne origin

Fast cutting, Clean cutting

The « Origin » hobs are characterized by the high precision of the profi le as well as the geometry of the whole tool. The bore tolerance (H3), the perpendicularity and the parallelism of the sides of the mill are essential features.
Louis Bélet goes further than just producing high quality tools. Listening carefully to the needs of our customers, we help them solving the troubles they may have in gear cutting. « Origin » hobs diff erentiate themselves especially in very small modules.

ORIGIN DUPLEX - Hobs cutter

Hobbing with two hob cutters is known to produce burr-free hobbing. It is a functional process, but requires a sometimes tedious start-up. It is necessary to make an adjustment for each hob, and the stacking of the arbor, tools and spacers results in a bad roundness and warping.

Louis Bélet SA has found a simple solution that can be used by everyone to solve these problems: ORIGIN DUPLEX hobs.

Made of one-piece solid carbide, these cutters have two cutting areas, one on the right and one on the left. The two profiles are spaced a multiple of the pitch.

This simplifies the setting. In addition, roundness and axial warpage are greatly reduced.

REVOLUTION - Hobs for asymmetrical gears

1 Colonne revolution

Fast cutting, Positionning drawing

Our « Revolution » hobs allows the cutting of gears which have a special profile : non symmetrical, too deep or simply not feasible using a classical gear cutting hob. The hob is delivered with the positionning drawing.

E2F - Hobs for frontal gear cutting

1 Colonne E2F

Short cycles, Burrs avoided

Frontal gear cutting creates sometimes a burr problem. The « E2F » hobs from Bélet decreases drastically these burrs by integrating roughing and finishing teeth, while guaranteeing a perfect final shape of the desired profile.

TRINITY - Hobs for conical gears

1 Colonne trinity

Positionning drawing, All kinds of profiles possible

Cutting conical pinions or gears is also a specialty from Louis Bélet. Our Trinity tool allows cutting of all kinds of conical gears, whatever the tooth shape and the module are. These hobs can be used on any gear cutting machine.
