Knurling Methods/Tooling

[Crashmaster]

Hi guys. I do a reasonable amount of knurling throughout the course of a year, generally on mild steel. Up to this point, I have been using a standard bump knurl on my CNC lathe. This seems to be pretty rough on the machine however, as the amount of pressure needed to form the knurls is quite a bit. We are looking into purchasing a new knurling system for the lathe and I would like some input into what has worked or not worked for others. Cost is not really an issue. I would like to hear the Zones thoughts on this. Thanks.

No takers on this thread yet? There has got to be a knurling guru on the forum somewhere...

Boni tools function in a fundamentally different way to conventional knurling tools.

The wheels machine the workpiece tangentially, so there is no lateral pressure on the work or cross spindle bearings. The operating forces are absorbed by the tool, regardless of whether it is cutting or rolling.

Depending on the type of knurl and quality of material, we are able to cut or roll the knurl with the same tool.

The wheels are mounted on precision ground spindles which run in needle roller bearings for smooth operation and long life.
Every knurling tool is supplied with setting tools and an operating manual
