Jay,
Good to keep the rpms low if you have vibration.
Thanks for the good words about the web site, the tools are selling, so must be working.
I do not have any info posted on the zone about my machine build. I built it from a36 hot rolled steel, 9"x6"x7" travels, hardened and surface ground ways, servo driven on 3 axis plus servo on spindle to 10000rpm. 3 angular contact bearings in spindle assembly, with retention knob style tool holders for quick tool changes. The tools holders are scaled down cat 40 design. The retention system has about 500lbs of spring force, with pneumatic tool release.
No tool changer
I quit my job as a tool maker several years ago, so I no longer have free run access to the kind of tooling and equipment I am used to. Designing a tool changer would be very frustrating to me without heat treating, grinding, cnc lathe, etc, etc.
A guy has to consider his machine finished at some point, right?
