Constantly growing customer demands on our products require us to monitor our services by strict quality control. The quality of our portfolio (with our main products gears and worm drive parts) is being ensured by the following measures:

• Air-conditioned rooms for measuring machines with an integrated storage place for the acclimatization of workpieces.
• OTT Worm Gears, as well as all common worm drives, are subjected to a single flank rolling test.
• Upon customer’s request, gearings of worm gears and worm screws can be measured on our measuring machines.
• Machine operators are performing quality measurements in the running production process.
• Depending on specification of the product, we provide documentation of testing and measurement results.
• Measurement results can be visualized graphically.
