Internal, active, and compensatory method and device for the rotational main-shaft of a cutting tool with axial bias-and-swing
The invention, relating to an internal, active, compensatory and method and device for the rotational main-shaft of a cutting tool with axial bias-and-swing, mainly applies an active technique to a gas-floating main-shaft to thereby control its bias-and-swing. A sensor at the exterior of the main-shaft directly measures the axial bias-and-swing of the cutting tool. Taking the measured data as feedback signals, the cutting point of the cutting tool is maintained at an axial positioning accuracy that is predetermined. Further, the invention is arranged with an electromagnetic controlling module to the mandrel's tail end at the interior of the main-shaft for taking non-contacting magnetic force to finely tune the axial position of the mandrel, such that an active compensatory function of the axial position of the cutting point of a cutting tool in action is achieved.
