you are both right and wrong, poly-milling is also known as polyform milling and yes, it can be achieved using x/z/c or x/y/z on a turning center.
Dont confuse this with polygon turning, for which you do need a syncro tool drive with the spindle, 1:1 or 2:1 to produce a hexaon for example.
polygon turning is very damaging to a lathe if the material is tough, it knocks the hell out of the tool drive and the spindle, due to intermittent cutting.
But they are totally different functions. |
