Hi,
I am in the process of buying a BF20 machine and looks a great machine but it is only 2250 RPM, this is really too slow for me.
I own a converted X1 that i put a belt drive conversion on to increase the speed to 4000RPM which worked great. i am looking to do the same with this machine but concerned about the spindle bearing and how will the hold up to the increase in speed. i plan to increase it to 5-6K. so any experiences of doing this upgrade and it implications would be good to have.
PS i want to go faster as i mainly make small parts that need small corner radii and tend not to run steel but ally jobs.
