Abstract
A worktable for numerical control machines, having a supporting structure hinged to the frame of the machine tool, and a faceplate fitted for rotation to the supporting structure to rotate, on command, about a first reference axis; the worktable having a first drive unit specially designed, on command, to rotate, and maintain rotation of, the faceplate at high speed about the first axis, and a second drive unit specially designed to vary, as required, the angular position of the faceplate about the first axis and with respect to a predetermined angular reference.
Claims23
A worktable for a numerical control machine tool, comprising a supporting structure fixed to a frame of said machine tool, and a faceplate fitted for rotation to said supporting structure to rotate, on command, about a first reference axis;
- said worktable comprising a first drive motor specially designed to rotate, and maintain rotation of, the faceplate at high speed about said first reference axis and located concentrically within a second drive motor specially designed to vary, as required, the angular position of said faceplate about said first reference axis and with respect to a predetermined angular reference, and wherein the second drive motor is selectively axially actuatable into and out of driving engagement with the faceplate.
