Internal & External Gear Cutting

Internal and external up to 500 mm diameter and module 8, straight and helical — our core trade

Gear cutting is our core trade: internal and external up to 500 mm diameter and module 8, straight and helical, on a Lorenz shaper and hobbing machine — as one-offs or small series.

What we do

External teeth, straight and helical, up to 500 mm diameter (hobbing, workpieces up to 400 kg), internal teeth up to 500 mm on the Lorenz SJ 7, splined shafts up to 800 mm length, sprockets up to 500 mm. Special profiles are cut with tooling procured specifically for the job.

What it gives you

  • Ground quality
    gear teeth to tolerances in the region of 0.0025 mm, with measurement report on request.
  • Special profiles possible
    we are not limited to the standard tool cabinet — missing profiles are procured as special tooling.

Typical problems this solves

  • A gear with an unusual module or profile is unobtainable
  • The turning shop can turn the part, but nobody will cut the teeth
  • A historic gear with unknown data has to be reproduced

What is on your bench?

Gearbox type and a few lines about your request — that is all we need for a first assessment. A photo helps but is not required. The answer comes from the machinist, not from sales.
