The present invention aims to solve a problem that a coating dead zone is formed when a matrix to be coated has a complex shape. To this end, the present invention provides a jig system which operates so as to allow a matrix to perform secondary torsional rotation for producing a torsion angle, in addition to rotation and revolution, thereby minimizing a coating dead zone. Also, the present invention provides a jig system which allows matrices to perform a vertical movement at the same time, thereby eliminating a coating dead zone. In particular, the present invention allows a jig to be operated so that a matrix shaped to form a helix angle, such as a milling tool or a drilling tool, performs torsional rotation which is synchronized with the torsion angle of the matrix. |
