Abstract

PURPOSE:To enable grooving of super-hard material without abrading the sidewall of band by reciprocating a blade applied with thin board of soft material burried with hard powder such as diamonds along the opposite side face sections of each band to be intruded into a work. CONSTITUTION:Predetermined tension is applied onto each band 10 in a blade 14 along the longitudinal direction to stretch said band 10 then reciprocate along the surface of super hard work while simultaneously the grinding liquid mixed with hard powder such as diamonds is fed to the cutting positions. Then through utilization of the force of the sidewall of each band 10 in the blade 14 for pushing the inner wall at the cutting section in the work during cutting, hard powder 20 in the grinding liquid is burried into one face of soft member 18 at the surface section of each band 10 to cut the work in round slices by means of the surface section of the soft member 18. Consequently, the super hard surface section of each band burried with diamond powder will grind and cut the inner wall at the cutting position of a super hard work resulting in highly accurate cutting without abrading the sideface of the band 10 in the blade 14.

Recently, with the emergence of ultra-hard materials similar to diamond, such as alumina ceramics, the blade 14 of the multi-blade cutting machine used for slicing the ultra-hard materials into thin plates or grooving them has changed. It became necessary.

However, using the conventional blade 14 described above, each band 10 in the blade 14 is coated while appropriately supplying a grinding fluid containing diamond powder or the like that matches the hardness of the workpiece to the cutting location of an ultra-hard workpiece. When cutting an ultra-hard material by moving it back and forth along the surface of the workpiece, the ultra-hard material is harder than the play F14 (harder than the D-bud 10, so the side wall surface of the band 10 made of steel or the like and the ultra-hard workpiece are cut). The abrasive material such as diamond powder in the above-mentioned grinding fluid that intervenes between the inner wall of the cutting part of the workpiece causes grinding wear between the side walls of the band 10, which is softer than the inner wall of the cutting part of the workpiece, and the conventional multi-blade It was impossible to perform slicing of ultra-hard materials with the blades of type cutting machines.

As a result of intensive research, the inventors of the present invention have developed the above-mentioned multi-blade cutting machine blade that can perform slicing of ultra-hard materials using conventional lapping techniques for ultra-hard materials.

That is, an object of the present invention is to provide a plurality of thin plate-like grinding bands with a certain gap between the side walls of each adjacent band, so that slicing of ultra-hard materials can be performed easily, accurately, and with high precision. , a flexible material that allows hard powder such as diamond to be embedded along the surface portions on both sides of the edge of each band that penetrates into the workpiece in blades of a multi-blade cutting machine that are arranged in parallel in an upright manner. The blade of a multi-blade cutting machine is made by applying a thin plate of the band, and the flexible blade allows hard powder such as diamond to be embedded along the surface area on both sides of the edge of each band that penetrates into the workpiece. The blade of a multi-blade cutting machine is constructed by arranging a plurality of thin plate-shaped bands made of thin plate-like materials in parallel with each other standing upright with a certain gap between the side walls of each adjacent band. ,
While reciprocating this blade along the surface of the workpiece, grinding fluid mixed with hard powder such as diamond is appropriately supplied to the cutting part of the workpiece. Using the force of pressing the inner wall of each band side wall in the blade, the hard powder in the grinding fluid is embedded into the flexible material surface of each band surface portion, and the soft material of each band in which this hard powder is embedded is It is an object of the present invention to provide a method of using a blade of a multi-blade cutting machine, which is characterized in that the surface portion of the workpiece is used to slice or groove a workpiece into a thin plate.

Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 shows a side cross-sectional view of the band portion of the blade according to the present invention, and 10 is a hard thin plate band-like band made of steel or the like, and the upper and lower edges of the band 10 are inserted into the workpiece. The surface portions on both sides of the section are respectively cut out to a predetermined depth in the shape of a step, and the step portion 16 is covered with a thin plate-like flexible material 18 such as copper and buried therein.

The other structure of the blade of the multi-blade cutter according to the present invention is the same as that of the conventional blade shown in FIG. 4, so a description thereof will be omitted.

Next, we will explain how to use the blade made of the above-mentioned specially structured band according to the present invention. The blades 14 of a multi-blade cutting machine are constructed by arranging the adjacent bands 10 in parallel to each other with a certain gap between the side walls of each band 10.
While applying a constant tension to each band lO in the blade 14 along its longitudinal direction, each band 10 is reciprocated along the surface of the ultra-hard workpiece, and at the same time hard powder such as diamond is removed. The mixed grinding fluid is appropriately supplied to the cutting part of the workpiece, and the force of the side wall of each band 10 in the blade 14 pressing against the inner wall of the cut part in the workpiece during the cutting process is used to cut the workpiece. Hard powder 20 in the grinding fluid interposed between the inner wall of the cutting part and the side wall of each band 10
The workpiece is cut into circular slices using the surface portion of the flexible material 18 of each band in which the hard powder 20 is embedded approximately on the surface of the flexible material 18 of each band 10 as shown in FIG. Cutting process. Then, similar to lapping an ultra-hard material, the ultra-hard surface portion of the flexible material 18 of each band in which diamond powder is embedded grinds and cuts the inner wall of the cutting area of the ultra-hard workpiece, and the blade An ultra-hard workpiece can be accurately and accurately cut into rounds using the blade without abrading the side wall surface of each band 10 in the band 14.

Note that the flexible material 18 is applied to the surface of each band 10 in the blade 14.
The adhesion structure of each band 1 is not limited to that of the above-mentioned embodiment.
The flexible material 18 may be applied only to the surface portions on both sides of either the upper or lower edge of the band 10, or as shown in FIG. A soft material 18 may be applied.

As described above, if the blade of the multi-blade cutting machine using the specially structured band of the present invention is used to perform slicing of ultra-hard workpieces, the side walls of the band in the blade will not be worn out and the blade will be accurate. Can accurately slice ultra-hard materials. In addition, the blade of the present invention has a hard core material made of steel or the like interposed throughout each band portion, and each band in the blade is strongly tensioned by applying a predetermined tension in the longitudinal direction. Since cutting can be performed by reciprocating each band in the blade along the surface of the workpiece, the workpiece can be cut accurately in a straight line without curved locus.

Furthermore, if a workpiece is cut according to the present invention, wear and tear of each band in the blade can be suppressed to a minimum, and the durability of each band in the blade can be greatly improved.
