Then, the method for using the disconnecting device cutting ceramic layer stack of the ceramic layer stack of the embodiment is carried out
Explanation.It is described as follows situation first:As shown in Fig. 2, in the state that ceramic layer stack 10 is placed on platform 20, without using such as
Guide device 21 shown in Fig. 3 cuts off ceramic layer stack 10.
As shown in Fig. 2, the defined position placing ceramic laminated body 10 on platform 20.Then, make platform 20 in arrow X
Direction on intermittently move, to keep off-position mobile and decline cutter 1 in specified position, cut off multilayered ceramic
Body 10.
At this point, angle control unit (not shown) according to predetermined distributed controll cutter 1 to ceramic layer stack 10 into
Enter angle so that the interarea 1s of cutter 1 and on the moving direction (direction shown by arrow Y) of off-position rearward than cutter 1
The angle, θ that the interarea 10s of the ceramic layer stack 10 in square region is constituted is according to predetermined changes in distribution.
Specifically, the angle, θ of cutter 1 is controlled and cut off according to predetermined distribution, so that with
Cutting is repeated in defined off-position, the angle, θ of cutter 1 becomes larger.Specifically, when cutting starts
It carves, angle, θ is set as 88 °;Near the middle position of the moving direction of off-position, angle, θ is set as 89 °;In cutting
Angle, θ is set as 90.5 ° by final stage.That is, by angle, θ control (referring to Fig. 2) in the range of 88 ° to 90.5 °.
Cutter 1 keeps what is be subject to from the stress that side is subject on the front of the position than being cut off and from rear side to answer as a result,
The balance of power can inhibit along inclined direction to cut off ceramic layer stack 10.As a result, not needing to sense each cutting, no
Productivity can be made to reduce, can accurately cut off ceramic layer stack 10.

Final stage, the case where making angle, θ become smaller again, (are not shown) in Fig. 3.As shown in figure 5, having period in the final stage of cutting
Prestige makes angle, θ become smaller again.
In addition, in this example, specifically, as shown in figure 5, control angle, θ so that cut off start when,
Angle, θ is about 88.2 °, since until breaks reach 15 times, angle, θ is gradually become smaller (in breaks 15 cutting
Angle, θ is about 87.8 ° when secondary), later until breaks reach about 130 times, angle, θ is become larger (in cutting time
When number is 127 times, angle, θ is about 91.2 °), angle, θ becomes smaller again later, and (when breaks are 140 times, angle, θ is big
About 91 °).
