One process fits all?

Why custom processes for edge rounding on carbide tools are vital

Edge rounding (honing) on carbide tools is an established process that extends tool life and improves PVD coating adhesion. Rounding and smoothing the cutting edges minimises the risk of microbreakage and significantly increases their mechanical stability. That’s the objective. Clear and simple.

But it’s the process that makes the difference, not the automation

Would you wear your favourite wool jumper all-year-round, everywhere you go, just because it’s there? We thought not. But that’s exactly how many companies approach cutting edge rounding. The most convenient solution is seldom the best if you want optimum results. The one-process-fits-all approach has the same effect on your tools as wearing said jumper in midsummer would have on you!

A universal process for drilling tools, milling tools, reamers and so on – ideally for every tool dimension – would obviously be wonderful. But experience shows it’s just not that simple. Professional, high-quality edge rounding depends on a host of factors including application area, material and geometry, to name a few. Using the same process for every tool would work now and again, but not very often.

Quality is dictated by the process – automation is just an added bonus

You need to consider each tool individually: what will it be used for and under what production conditions? Every tool has its specifics. The only guarantee of reliability, repeatability, cost-effectiveness and above all, quality, is a custom-developed process. If you can automate it as well, then great – you’ve got non-stop quality!
