Solid hobs

» Solid hobs

The steel hob achieved its breakthrough as a result of the ability to recoat at a reasonable price following the sharpening process.

  • Better profile form achieved through the use of a high number of gashes
  • von

  • Good chip distribution reduces strain on the cutting edges
  • Reduction of set-up time through extendibility of shaft or tandem hobs
  • Closer manufacturing tolerances achieved by applying more precise grinding quality

Powder-metallurgical high-speed steel together with the respective hard coatings can also be used for dry hobbing.

Solid carbide hobs

The carbide hob is particularly suited to large series production. It can only be used economically on the latest generation of modern hobbing machines.

  • Short production times through high cutting speeds
  • High quality surface finish
  • Suitable for dry machining
  • Very good service life, through use of appropriate hard-material coatings

Depending on the application, SAAZOR recommends the best suited type of carbide, hard-material coating and production technology.
