High-speed milling machine

A machining apparatus has a guide extending in an x-direction, an x-slide displaceable in the x-direction on the guide, a y-slide displaceable in a y-direction generally perpendicular to the x-direction on the x-slide, and a z-slide displaceable in a z-direction generally perpendicular to the x- and y-directions on the y-slide. A tool holder is pivotal about a holder axis generally parallel to the x-direction on the z-slide and carries a tool rotatable about a tool axis perpendicular to the holder axis on the z-slide. The tool holder and tool have a center of mass generally at the holder axis. An actuator tips the tool holder and tool relative to the z-slide about the holder axis on the z-slide.
