接着面にうねりがあると接着が不完全になる。When cutting a ceramic plate, it is necessary to hold it fixedly with a chuck, but since ceramic is a non-magnetic material, it is impossible to directly fix it to a magnetic chuck. Therefore, conventionally, as shown in FIG. 7, a ceramic plate 3 is bonded to a base 1 made of a magnetic material using an adhesive 2, and then the base 1 is attracted to a magnetic chuck 4, and a rotating grinding wheel 5 is used to attach the base 1 to the base 1. Amputations and knee injuries were performed. By the way, if the bonding surface of the ceramic plate 3 has undulations, the bonding will be incomplete.

したがって、あらかじめ研削加工を行なって平坦面にす

。Next, the order of cutting the ceramic plate 15 using the cutting jig configured as described above will be explained. First, the ceramic plate 15 is placed on the base 11, and the X-direction mounting is performed using the fixing bolts 14 provided diagonally downward on the base 12.12.
... to press the end face of the ceramic plate 15 in the X direction. By pressing the end faces diagonally downward with the fixing bolts 14 facing each other in this way, it is possible to prevent the ceramic plate 15 from floating up, and it is possible to fix the ceramic plate 15 to the base 11. Next, the planned cutting line X in the X direction of the ceramic plate 15 is positioned on the grinding wheel of the grinding machine, and the grinding wheel is set so as to bite into the recess '16 of the base 11. When the base 11 to which the ceramic plate 15 is fixed is moved toward the grinding wheel while the grinding wheel is in zero rotation, the ceramic plate 15 is cut in the X direction, and a plurality of cut pieces 15a... are obtained. . Next, for installation in the Y direction, an auxiliary jig 18...
When these are fixed with bolts 19..., spacer parts 2o... protruding from the lower surface of these auxiliary jigs 18...
intervenes in the gap Q between the cut pieces 15a... to keep the gap Q constant and prevent the cut pieces 15a from moving in the Y direction. Furthermore, each cut piece 15a...
In order to fix it to the base 11, the tightening screws 21 provided on the auxiliary jig 18 are tightened downward, and the tightening screws 22... are tightened upward. As a result, each cut piece 15a of the heramic plate 15.
... are clamped and fixed by tightening screws 21 and 22 from above and below. In this state, when the planned cutting line y in the Y direction of the ceramic plate 15 is opposed to the grinding wheel and the base 11 to which the ceramic plate 15 is fixed is moved in the Y direction, each cut piece 15a... is cut along the planned cutting line in the Y direction. Cut along y.
