    I believe there was a thread several years back posted by Hoss on various upgrades for the G0704, One of the mods was replacing the OEM spindle bearings with high speed bearings.

    High speed spindles are quite common - I have seen some on commercial multi-axis machining centers that can run in excess of 30,000 rpm. Precision balancing of the tooling is a must with high speed spindles.

    I misspoke - most of Hoss' upgrade articles were posted on CNCZone

    You can also find them at: www.G0704.com
