A high-precision turning device. The device has a base plate, a base, a support A, wherein a groove is formed in the center of the bottom surface of the base, and a lead screw passes through the groove; symmetrical T-shaped annular grooves are formed in two sides of the interior of the base, two symmetrical T-shaped annular columns are arranged on the lower end face of a turning block, and the T-shaped annular columns can be inserted into the T-shaped annular grooves; and the structure of a central position of the lower end face of the turning block is annular teeth, and the annular teeth are meshed with the lead screw. A servomotor drives the lead screw to rotate, and by virtue of meshing matching of the annular teeth and the lead screw, the turning block can turn along the centers of the T-shaped annular grooves in the base.

A numerical controller looks ahead and analyzes commands indicated by a block contained in a program, and identifies a travel direction of a control target for each of the commands to calculate a time constant based on the identified travel direction. The numerical controller then sets a time constant for filter processing based on the time constant for each of the commands, and performs filter processing on command data subjected to a linear acceleration and deceleration process, based on the set time constant. The numerical controller then calculates movement of each axis for each interpolation period, based on the command data subjected to the filter processing.
