I have a TL-2 and a TM-1. I have increased the spindle rpm to 6000 on the mill and was wondering if anyone has done this to the lathes. Haas has an option for higher RPM on the lathe but I think that this is due to different pullys. Any Idea on the max safe RPM and rapids on the TL lathes. My chuck is rated to 2700 RPM and would like to up the machine to that.
