Materials and manufacturing-procedures in modern production sites:
We process case hardening steel, tempered steel, nitrided steel, construction steel, aluminium, bronze, various cast alloys and plastic for CNC-turning and milling, hobbing, gear shaping, broaching, hard machining, tooth flank grinding, lapping,  external and internal cylindrical grinding depending on material and your application.

Heat treatment and coating:
Required heat treatments such as case hardening, long term / short term gas nitriding, plasma nitriding (ion nitriding), inductive heating, tempering or coating we let execute by specialized ISO 16949 - certified partners.

Types of gear cutting in our spectrum of production:

Spur gears:
Straight, helical or double-helical:
Ø 20 mm -up to  Ø 2500 mm
Module 0.5 - module 32
Tooth width max. 1000 mm

The tooth flanks are milled, shaved or ground according to the customer's specifications.
Thus we can meet also your higher demands about gear quality.
Because of our many years of experience we have the know-how to ensure, depending on the component, a gearing quality of up to 4 acc.
permanently and in documented manner.
