BASE DIVIDING DEVICE AND BASE DIVIDING METHOD

摘要

PROBLEM TO BE SOLVED: To inhibit damage such as chips generated on the edge part of a hard base divided along a dividing line.;SOLUTION: This base dividing device X divides the hard base S with a split groove P of the lower surface formed along the dividing line D-D, parallel with the dividing line D-D. In addition, the base dividing device X comprises the following components: (1) a support rest 1 with the split groove P of the lower surface of the base S which is so arranged as to be positioned in the middle and also, with a first support part 11 and a second support part 12 which support the lower surface of the base S respectively in the direction where the dividing line D-D extends, and (2) a pressing member 3 which presses a position deviated from the center of the base S in he direction where the dividing line D-D extends, on the dividing line D-D of the upper surface of the base S.;COPYRIGHT: (C)2011,JPO&INPIT
