I started a job a few months ago and we have a few Tornos Bechler ENC16 with Fanuc O-T controls. This is my first contact with Swiss Type machines, so pardon my ignorance.
I am learning by studying the existing programs, and one thing that caught my eye are the feed and speeds used, they seem very slow to me. Mostly we machine .500 dia. or less 300 series stainless. The feed rates range from .0008 IPR to .002 IPR, with spindle RPM in the 1000, to 2800 range. I assume, since there are hundreds of programs that exist, all programmed the same way, that there must be a reason for the slower feed rates on these machines? If anybody can enlighten me as to why this is I'd greatly appreciate it.
