Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to glass, ceramics, ferrite, copper conductor powder, magnetic materials 1. The present invention relates to a workpiece to be cut, which is suitable for cutting extremely thin slices used in electrical/electronic components, such as O-modules, from a workpiece such as a superalloy.

Conventionally, relatively small-sized workpieces have been formed into appropriately sized blocks using an adhesive, then adhered to a workpiece holding material such as glass, Bakelite, or carbon sintered material, and then sliced.

However, these workpiece holding materials are both hard and brittle, so they can be shaped like J by using a diamond blade.
It is easy to be damaged at the notch part of the adhesive surface of the workpiece that is A.
There was a certain limit to the slice thickness that could be processed. Also,
A hard and brittle workpiece holding material, together with a workpiece that has the same properties, not only slows down the wear of the blade edge and impairs its sharpness, but also clogs the blade edge and impairs the finishing accuracy of the cut surface. However, the thickness of slices that can be cut is severely limited.

Therefore, if the thickness of the slice required for ■C etc. is thinner than the thickness that can be cut by the blade,
After slicing the workpiece to a thickness that can be sliced, the slices were polished by lapping to a predetermined thickness, which increased the number of steps, required extra manpower and cost, and caused material loss due to polishing. The number of slices that can be cut from the workpiece decreases accordingly.
There is an inconvenience that as the thickness of the slice piece becomes thinner, the cost required for processing increases significantly.

Furthermore, the workpiece holding material, which is separated from the sliced piece after processing and thrown away, is relatively expensive as a consumable material and is nonflammable, so cleaning up after processing requires time and expense.

The entire purpose of the present invention is to provide a workpiece to be cut that eliminates all of the above-mentioned disadvantages.

6'4 composition of the present invention? To explain an example, a workpiece holding plate 1 made of bamboo material has a workpiece adhesive surface 1b formed at right angles to the length direction of the property fibers 1a, and the surface of a workpiece 3 bonded to the workpiece adhesive surface 1b is bonded with an adhesive 4. It is characterized by consisting of a workpiece auxiliary plate 2 made of bamboo material which is held on a workpiece holding plate 1 by means of the following.

When the size of the workpiece 3 (both the single piece 3A and the aggregate 3B are attached) to be adhered to the workpiece adhesive surface 1b with the adhesive 4 is small, the workpiece holding plate 1 is a single piece IA made from a bamboo trunk. However, when the size of the workpiece 3 exceeds a certain level, the bamboo cut to a predetermined length is divided lengthwise, and each divided piece IBl'r
Adhesive 4 so that the direction of those fibers 1a matches
It is sufficient to use an integrated body IB made by bonding (Fig. 4).

The work auxiliary plate 2 is made of a single piece of bamboo like the work holding plate 1.
A or an aggregate IB of divided pieces IB1, but when bonded to the surfaces of the workpiece holding plate 1 and the workpiece 3 with the adhesive 4, the direction of the fibers 2a is the same as the direction of the fibers 1a of the workpiece holding plate 1. match.

Next, the workpiece auxiliary plate 2 performs a second operation of cutting the slice piece 3a by the slicing machine using workpiece holders attached to both left and right sides of the workpiece 3 as shown in FIG.
The figure and FIG. 3 will be explained. Inner blade 6 of donut-shaped diamond blade 5 rotating in the direction shown by arrow Q
To attach the workpiece 3 located inside the slicing machine, use the jig 7 to process and feed it in the direction shown by the arrow P from the position of the solid line to the position of the imaginary line, and return it to the original position of the solid line I-
Thereafter, by repeating the operation of moving the workpiece 3 vertically downward (arrow R) by the desired thickness, slice pieces 3a of a predetermined thickness are sequentially cut from the bottom of the workpiece 3.

In this case, the inner edge 6 of the blade 5 slices the harder workpiece 3 bonded to the workpiece auxiliary plate 2 made of bamboo material, which has toughness and elasticity. Even when the length of the workpiece 3 protruding from the workpiece adhesion surface 1b is long, the slice piece 2b of the workpiece auxiliary plate 2 cut along the line 2a can be held horizontally by the slice piece 3ai of the shaker 3 due to its elastic action. Therefore, the sagging of the tip is 9, which prevents chattering during machining. Further, the workpiece 3 is moved to the position of the virtual line, and a cut 8 is made on the workpiece adhesive surface 1b with the same thickness as the slice piece 3a.
Even when the cut 8 is formed, the direction of the cut 8 is the same direction as the fibers 1a of the workpiece holding plate 1, and the workpiece holding plate 1 has the same toughness and elasticity as the workpiece auxiliary plate 2. , the cut piece 1c between the cuts 8, 8 is not damaged by the blade 5 and the slice piece 3a (5
Hold securely. Moreover, this holding effect is extremely effective when the workpiece 3 is sliced into ultra-thin slices of about 50 microns, which is about 4 mm thick than the conventional thickness. This not only improves processing efficiency, but also eliminates the material loss of the workpiece 3 due to the rubbing/grooving process, significantly increases the number of slices 3a that can be cut from the workpiece 3 of a constant thickness, and reduces the manufacturing cost of the slices 3a. be able to.

In addition, the workpiece holding plate 1 and the workpiece auxiliary plate 2 are softer than conventional holding materials and cause less wear on the inner cutter 6 of the blade 5, and each tip of the cut fibers 1a+2a is Because it has the effect of completely removing clogging from the workpiece,
To maintain the sharpness of a blade 5 and extend its life.

In order to separate the multiple slide pieces 3a, one end of which is held by the workpiece adhesive surface 1b, from the workpiece adhesive surface 1b, the adhesive portion of the workpiece 3 must be separated from the workpiece adhesive surface 1b. What is necessary is just to immerse it in the solvent of adhesive 4 for a certain period of time.

The workpiece auxiliary plate 2 does not necessarily need to be attached to both the left and right sides of the workpiece 3, and the workpiece 3 from the workpiece adhesion surface 1b.
When the protruding length of the blade 5 is relatively short, the inner cutter 6 of the blade 5
The same effect can be obtained even if the adhesive is bonded only to one side of the side S where the cut 9 is made in the workpiece 3.

FIG. 5 shows another embodiment in which workpiece auxiliary plates are adhered to the top, bottom, right and left sides of the workpiece and held by the workpiece holding plate.

When the workpiece 3 is sliced into ultra-thin slices from the bottom side with this configuration, the workpiece auxiliary plate 2 glued to the bottom side of the workpiece 3 will be
Together with the workpiece auxiliary plates 2 bonded to both the left and right sides of the workpiece 3, it is possible to more effectively prevent the tip of the slice piece 3a from sagging and chatter, thereby further improving the dimensional accuracy of the slice piece 3a that can be cut. can.

It goes without saying that the workpiece auxiliary plate 2 may be bonded not only to the top and bottom, left and right sides of the workpiece 3, but also to the first surface of the blade 5 near the inner cutter 6.

In each of the above embodiments, the workpiece 3 has a rectangular parallelepiped shape, but the workpiece 3 can also be a cylinder, such as optical glass.

FIG. 6 shows an example of this, in which the workpiece 3 is attached to each abutting part of the workpiece holding plate 1 and the workpiece auxiliary plate 2 using adhesive 4.
It is glued by. In this case as well, the entire workpiece 3 can be cut into ultra-thin slices, as described in each of the above embodiments.

As explained above, according to the present invention, it is possible to eliminate damage to the notch on the adhesive surface of the workpiece and prevent the top end of the sliced piece of the workpiece cut by the workpiece auxiliary plate from collapsing and chattering. It is possible to omit machining and efficiently perform ultra-thin slicing of a workpiece using a workpiece holder that is inexpensive and requires no effort to clean up afterwards. In addition, the work holding plate and work auxiliary plate made of bamboo material reduce wear on the cutting edge of the blade, maintain good sharpness, and prolong the life of the hemorrhoid.
