All grinding work is carried out in IMAS’ own factory. An in-depth knowledge of the processes, techniques, materials and machines involved is essential to guarantee a quality finish.

In particular, the IMAS machine park includes:

  • twelve gear grinding machines;
  • four worm shaft grinding machines;
  • one beveloid gear grinding machine.

 

Grinding operations are classified differently depending on the purpose of the work and the type of finished surface to be achieved.

To find out more about the characteristics of the machines in the IMAS machine park.

In gear generating grinding, the flanks of the teeth are formed by a generating process in which the grinding wheel does not have a specific shape for each type of gear. In gear shaping grinding, the profile of the grinding wheel matches the shape of the space between two tooth flanks. Every gear profile therefore requires a specific grinding wheel.

Internal gear grinding is carried out to eliminate the deformation induced in metal components by thermal treatments. The purpose of this precision grinding operation is to obtain surfaces that conform to technical specifications and that therefore guarantee the required functionality: gear profiles must be absolutely perfect to permit high performance.

External gear grinding is a process used to finish the surfaces of mechanical components. It is applied to different types and sizes of external gear teeth in order to ensure smooth meshing and reliability.

Cylindrical gears are the most common type of gear found in mechanical power transmission systems. They require extremely accurate internal and external grinding on highly accurate and reliable machines.

The external grinding of worm shafts requires specialist know-how and accurate measurement of all characteristics, both dimensional and geometric, as well as verification of surface roughness. All these operations are essential to high efficiency and low-noise functioning.

Pinion grinding is another precision machining operation. Pinions are another important transmission component and require an excellent surface finish to mesh with larger gears and to ensure the correct functioning of the drive systems in which they are used.

Beveloid gears are helical cylindrical gears obtained by angling the hobbing tool with respect to the cylinder. Beveloid transmissions are geometrically complex and demand a high level of precision from the grinding process.
