Positioning and rotating workpiece in machine tool - employs separate axial and radial supports one of which is vibrated at ultrasonic frequency during machining

A workpiece (1) shaped as a body of revolution with a plane face, is supported against separate axial and radial supports (3, 2) and is rotated by a rotary driving member (5). This has frictional contact with the workpiece. At least one of the supports is vibrated at ultrasonic frequency in a direct...

Zusammenfassung:A workpiece (1) shaped as a body of revolution with a plane face, is supported against separate axial and radial supports (3, 2) and is rotated by a rotary driving member (5). This has frictional contact with the workpiece. At least one of the supports is vibrated at ultrasonic frequency in a direction parallel to, or inclined at an angle a not greater than 10 degrees to, the line of contact between the workpiece and the support. The ultrasonic vibrations are of asymmetrical waveform during at least a part of a machining operation on the rotating workpiece.
