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 assigned to a gear, the higher the accuracy of the workpiece (for AGMA standards, in fact, is true the exact opposite). This means that a DIN 5 grade gear is a very accurate workpiece and – more generally – a value of this type is obtained after grinding.
We however set ourselves the goal of becoming more familiar with the skiving technology, so as to approach the grinding threshold as close as possible.
But why specialise in skiving rather than grinding? To start with, because grinding is not a process that MICROingranaggi performs in-house and then, even if it did, it would cost much more. A grinding machine, in fact, is a rather expensive machine per se, and can only be used for that specific function.
The gear hobbing machine we use for skiving, on the other hand, is a machine that we already have at our factory and it’s a vital piece of equipment as any gear must be toothed before the grinding phase.
So, if just a couple of years ago i thought it impossible to achieve a DIN 5 quality grade in a batch of 100 pieces using skiving technology, today i find it impossible to do the same for a batch of 10,000 pieces. But who knows, maybe in another two years we will achieve that too….
