Skiving of a 26 tooth, module 1.5, DIN 5 quality level gear

If just two years ago someone had asked me whether it was possible to achieve a DIN 5 quality level of a 26 tooth, Module 1.5 gear for a batch of 100 pieces using skiving technology, I would have said no. Absolutely not. Yet we have achieved just that. As the majority of you probably know the ISO standards, on a scale from 1 to 12 the lower the value...

Production of satellites for a 18mm diameter epicycloidal reduction gear

In the video below we are producing toothed satellites for a 18mm diameter epicycloidal reduction gear on a Lambert 90 CNC with automatic loader and vibrating storage. The Lambert 90 is a hobbing machine deriving from a modified traditional machine and devised to produce reduction gears for the watchmaking industry. Although it may appear to be small, the...

Skiving of a 1.25, 9-teeth 58HRC gear module on a Koepfer K160 CNC

In the video below our gear hobbing machine Koepfer K160 CNC is skiving a 1.25, 9-teeth 58HRC gear module. As many of you probably know, tooth hobbing referred to as skiving is a recent concept used for finishing the side of the gear teeth as to eliminate any deformations caused by thermal treatment. But given that it’s performed after a thermal...

Dimensional control of a module 0.5 worm screw with a Klingelnberg P26 involute gear measuring centre

Here is our Klingelnberg P26 involute gear measuring centre at work while performing the dimensional control of a module 0.5 worm screw. As often happens when dealing with precision micro-mechanics, the part in question is rather complex to produce, and not only because of its limited tolerances. This worm screw in particular is, in fact, produced in...

Gear  Ø3.1, 12 teeth, module 0.21. Was it more difficult to build it or certify it?

In this video our Klingelnberg P26 4-axes CNC evolventimeter is certifying a gear with Ø3.1, 12 teeth, module 0.2. Was it more difficult to build it or certify it? The question is obviously provocative, as there is no clear cut answer. Building such a small part involves placing it on the hobbing machine, devising a way to keep it firmly in place and then...
