Abstract
Z방향에서 평행하게 연장되는 스핀들(27,229)를 갖는 공작기계(1,227)는 Z방향에 평행한 회전축(29,231)에 대해 회전가능하며, 작업물(35,237)용 홀더(33,235)를 구비하고 있다. 공작기계(1,227)는 Z방향에 수직한 X방향에 변위가능한 도구(13)를 홀더(11)를 가진다. 스핀들(27,229)과 도구(13)용 홀더(11)는 도구(13)이 X위치의 함수 및 스핀들(27,229)의 회전각으로 Z방향에 평행하게 상호 변위하여 작업물(35,237)에 회전축(29,231)에 대해 비회전 대칭인 표면을 제공한다. 본 발명에 따라 스핀들(27,229)와 홀더(11)는 스핀들(27,229)만은 Z방향에 대해 평행하게 변위하게 하여 Z방향에 평행하게 상호 변위한다. 작업물(35,237)은 그러므로 소망하는 기본 표면과 비회전 대칭인 소망 수정면을 구비하며, 일렬의 작업물을 다른 기본 표면을 가지고 수정은 단지 하나의 도구에 의해 제조된다.The machine tools 1,227 having spindles 27,229 extending in parallel in the Z direction are rotatable about the axes of rotation 29,231 parallel to the Z direction, and are provided with holders 33,235 for the workpieces 35,237. The machine tool 1, 227 has a holder 11 with a tool 13 displaceable in the X direction perpendicular to the Z direction. The spindles 27 and 229 and the holders 11 for the tool 13 have a rotation axis 29 and 231 on the workpieces 35 and 237 as the tool 13 is mutually displaced in parallel to the Z direction as a function of the X position and the rotation angle of the spindles 27 and 229. Provide a surface that is non-rotationally symmetric about. According to the present invention, the spindles 27 and 229 and the holder 11 are mutually displaced in parallel to the Z direction so that only the spindles 27 and 229 are displaced in parallel to the Z direction. Workpieces 35 and 237 thus have a desired crystal surface that is non-rotationally symmetrical with the desired base surface, with the other base surface in line with the workpiece and the crystal is produced by only one tool.
