A power operable bone facing cutter has a body with a pilot hole or stem for orientation with the bone to be faced. A cutter disk is removably fastened to the working end of the body and has a cutting edge lying in a plane perpendicular to the pilot axis. The cutting edge extends from a circle centered on the axis, outward to an outer circular edge. The cutting edge is at an angle with respect to a radius from the axis to cut toward the axis as the cutter is rotated. A chip escape slot is provided in the disk and body above the cutting edge. The rest of the bottom surface of the cutter disk is flat to provide a supporting surface spaced at a gage height from the plane of the cutting edge to provide optimum cutting while the supporting surface prevents excessively rapid or deep cutting, thus producing a skiving action.

A scanning tunneling microscope is disclosed which includes a frame assembly having upper frame members coupled to lower frame members by an external vibration isolation structure, a sample carousel configured to receive at least one sample to be scanned, and a probe carousel configured to receive at least one probe module including a probe tip. The sample and probe carousels are coupled to the upper frame members and sample and probe actuators are provided to rotate the carousels. A positioning mechanism is used to maintain a scanning distance between the probe tip and the sample carousel. A control unit controls the overall operation of the actuators to rotate the carousels and the operation of the positioning mechanism to maintain the scanning distance.
