摘要 |
An apparatus for boring a laminated plate includes a table having a first surface on which a laminated plate may be placed for boring and an opposing second surface, the table defining at least one passage therethrough; a supporting pad for urging a laminated plate to be bored towards the first surface of the table; and a cutter for boring a laminated plate to be bored, the cutter operable to bore in a direction generally opposite to the direction that the supporting pad urges and through the passage defined by the table. Further according to the present invention, the cutter includes a knife edge, a pivotal mechanism adapted to be pivoted about its axial center line, and a stepping mechanism (5) for moving the knife edge in one direction and unsuccessively further in a second direction so that successively deeper boring may be performed. Also according to the present invention, a boring cutter having an axial center line about which the cutter is operable to be rotated includes a cutting element having a modified round-bar shape. Still further, according to the present invention, a method of boring a multi-layer laminated plate includes the steps of pressing against the plate in one direction; and boring the the plate in a direction opposite to the direction in which it is pressed, the boring characterized in that a boring element is withdrawn between boring of each individual layer of the multi-layer plate. |
