Description

Manufacturing method of grinding tool and cutting tool by brazing method {MANUFACTURING METHOD FOR GRINDING AND CUTTING TOOL USING METAL BRAZING}

The present invention relates to a method for manufacturing a polishing / cutting tool by the brazing method, and more particularly, using a mesh of polymer material having a mesh to uniform abrasive grains, such as diamond particles, in a fluid paste-type brazing metal binder. To provide a way to do this. In addition, the present invention provides a method for manufacturing a polishing / cutting tool by a brazing method that can form an abrasive layer composed of a plurality of abrasive grains in one layer or multiple layers, and a polishing / with one layer or multilayer abrasive layer manufactured by the above method. Provide cutting tools.

The present invention can be applied to diamond tools in ultra precision fields such as chemical mechanical pad conditioners. In addition, general precision grinding tools such as straight wheel, ID wheel, stone construction cutting tools such as coredrill, cutter, blade, wire saw, Or it can be applied to an end mill (stone) for stone drilling.

In general, such an abrasive tool or cutting tool is composed of a base material, a plurality of abrasive grains coupled to the base material to polish or cut an abrasive or cutting object, and a coupling member for coupling the plurality of abrasive grains onto the base material. do. As a method of bonding the base material and the abrasive grains, electroplating by electroplating by nickel, a sintering method of sintering the entire base material in which the metal powder as the binder and the abrasive grains are distributed, or a plurality of the abrasive grains as a binder made of brazing metal And a brazing method to be fixed thereto.

In particular, in the case of the brazing method, the binder for fixing the abrasive grains on the base material generally consists of a metal powder and a paste composed of a binder or the like to have fluidity to the powder. That is, in the brazing method, a paste consisting of a metal powder and a binder is first applied onto a base material, and a plurality of abrasive grains are distributed on the paste applied to the base material. Next, the paste having a plurality of abrasive grains is dried at a predetermined temperature, and then heat-treated at a predetermined sintering temperature (about 900 to 1300 ° C.) in a reducing atmosphere or an inert atmosphere to melt and fix the brazing metal to complete a product. .

On the other hand, when the distance between the abrasive grains in the polishing / cutting tool is too far apart, the structure of the polishing surface or the cutting surface may be defective. For this reason, the workload (for example, the impact force exerted by the workpiece) added to each abrasive grain becomes excessive. Randomly dispersed particles may also be comminuted or removed from the matrix in which these particles are to be placed. If some of the abrasive grains are broken or removed, the workload is transmitted to the remaining abrasive grains, thereby increasing the probability of the chain breakage of the other abrasive grains. In addition, if the distance between the abrasive grains is too close to each other, the particles may overlap, in which case there are abrasive grains that are not used at all in the actual work. In particular, diamond or boron nitride and the like is very expensive, which is not preferable in terms of cost. In addition, the non-executive particles not used in the work as described above can block the passage of the debris, the work efficiency is significantly reduced.

In order to solve the above problems, conventionally, a method using a perforated plate has been used as a method of uniformly distributing abrasive grains on a base material. In more detail, when manufactured by the sintering method, first, an adhesive tape is attached to one surface of a perforated plate having perforated holes formed at regular intervals larger than the size of the diamond particles, and diamond particles are uniformly arranged on the tape through the perforated holes of the perforated plate. Glue. In this way, when the perforated plate is removed after the arrangement of the diamond particles is completed, the diamond particles are uniformly arranged so that only the attached adhesive tape remains. Thereafter, the metal binder powder is filled between the arranged diamond particles, and then manufactured by integrally molding. In addition, in the case of the electroplating method, after the adhesive is applied on the base material, diamond particles are arranged through a perforated plate or a mesh, and a method of forming a gold metal for bonding and holding the diamond particles by electroplating is performed. .

As described above, in the electroplating method or the sintering method, the adhesive tape or the adhesive is attached to the base material to attach the abrasive grains filtered through the perforated plate or the mesh. However, in manufacturing the polishing / cutting tool by the brazing method, since the brazing metal matrix is a paste in a gel state, the perforated plate used in the electroplating method or the sintering method using powder as described above or It is not easy to place the diamond particles by placing the mesh on the paste. In other words, when the perforated plate or the mesh is placed on the fluid gel paste, the paste state is impaired, which makes it difficult to disperse the diamond. In addition, the setting process using the perforated plate has a problem that the manufacturing cost is increased because the cost is very expensive.

In the brazing method, an example in which diamond particles are uniformly arranged using a template such as a perforated plate (Korean Patent Laid-Open No. 2001-60975) includes a solder itself or powder thereof mixed with an organic adhesive (for example, wax) and a roller. After forming the rolled peeled metal layer, there is a method of arranging diamond particles in the metal layer using a template with regularly distributed holes. However, the formation of the peeling metal layer by mixing the metal powder with the organic adhesive brings about an increase in cost in that a separate adhesive layer must be prepared without using a paste as in the conventional brazing method.

The present invention was devised to solve the above problems, and an object of the present invention is to provide a method for uniformly disposing abrasive grains such as diamond in a paste-type brazing binder using a perforated plate or a mesh. The abrasive / cutting tool manufacturing method provided by the present invention enables the abrasive grains to be uniformly arranged in a faster and easier manner without increasing the manufacturing cost.

Furthermore, another object of the present invention is that, when the paste-type brazing binder is used, when the paste is not completely dried, the paste flows in the gravity direction when the product is charged into a furnace and heated. Therefore, a defect such as thickness deviation occurs in the product, and eventually, the problem that the product must be disposed of is solved. According to the polishing / cutting tool manufacturing method provided by the present invention, the above-mentioned problem is solved because it includes a step of drying the fluid paste in advance.

In addition, the present invention is to provide a metal brazing method (Metal Brazing Multi Layer) comprising a plurality of layers as well as a metal brazing (Metal Brazing Single Layer) in the manufacture of polishing / cutting tools by the brazing method It is done. Through this, even if the abrasive grains of the surface layer can no longer continue to work, the subsequent abrasive grains are manufactured in such a structure that the protrusions can be continued without continuing the life of the tool.

By drying the fluid paste binder layer in advance before installing the abrasive disposition means in the binder layer, it is easy to install the abrasive disposition means, and also by applying a liquid binder to the surface of the first dried binder layer, the abrasive particles can be adhered. To help. Therefore, it is possible to evenly arrange a plurality of abrasive grains by using abrasive grain arrangement means such as a perforated plate or a mesh.

Hereinafter, a polishing / cutting tool manufacturing method by the brazing method according to the present invention will be described with reference to the drawings.

1 is a flowchart illustrating a method of manufacturing a polishing / cutting tool by a brazing method according to a first embodiment of the present invention. As shown in Figure 1, the manufacturing method of the polishing / cutting tool by the brazing method according to the first embodiment of the present invention, the step of preparing a base material (S1), applying a paste-like binder layer (S2), The first drying step of drying the binder layer (S3), the step of applying a liquid binder on the surface of the dried binder layer (S4), the step of installing the abrasive grain disposition means in the adhesive layer formed by the liquid binder (S5) Dispersing and arranging the abrasive grains using the abrasive grain disposing means (S6), separating the abrasive grain disposition means from the adhesive layer (S7), secondary drying step of drying the fluid adhesive layer (S8), and a plurality of Through the step (S9) of drying the entire base material in which the two abrasive grains are disposed in an oven (S9), and charging the entire base material in a furnace (S10) to complete the final product.

In more detail for each process step, as shown in Figure 2 (a), the binder layer 40 in the form of a paste is uniformly applied on the base material (20). The base material to be used is configured to have a variety of shapes and materials depending on the use, the material is preferably a metal material, more preferably based on stainless steel (stainless steel). However, if the environment is not corrosive, it is possible to use ordinary steel, and carbon steel such as SK5, SCM, S45C (Japanese Industrial Standard) can be used.

In addition, any one of Ni-based paste, Cu-based paste, or Ag-based paste may be used as the paste 40 applied on the base material 20 of FIG. 2A, and may be selected according to the purpose of the product. It is preferable to use Ni-based brazing metal with a high hardness. The paste binder layer 40 is preferably applied uniformly on the base material, and the thickness to be applied is determined depending on the size of the abrasive grains to be bonded, but is usually applied in a thickness of several micrometers to several thousand micrometers. The paste binder layer 40 serves to bond the abrasive grain and the base material, and includes a solvent and a binder.

Next, as shown in FIG. 2 (b), the paste binder layer 40 is uniformly coated on the base material as described above using a drying means such as an industrial dryer. Dry with tea. At this time, it is preferable to dry with hot air 60 whose temperature is 300-600 degreeC, and it is more preferable to divide and dry several times every several minutes as needed. If the drying time is too short, the binder continuously elutes at the bottom of the paste, and the paste is not completely dried. Therefore, the binder is dried until the bottom binder does not rise on the paste surface. The purpose of such primary drying is to remove the solvent since the solvent is usually volatilized at about 100 ° C. and the binder is volatilized at about 500 ° C.

After all of the paste binder layer 40 is dried, the liquid binder is re-coated on the dried paste binder layer 40 as shown in FIG. 2 (c). This is because the dried paste is moistened by applying a liquid binder to form an adhesive layer 41 to which the abrasive grains can be attached to the paste binder layer 40.

Next, after installing the abrasive grain disposing means 80 on the adhesive layer 41 moistened by applying a liquid binder as shown in Fig. 2 (d), a plurality of abrasive grains 10 as shown in Fig. 2 (e) thereon Disperse Thereafter, when the abrasive grain arranging means 80 is removed, only the plurality of abrasive grains 10 remain on the paste adhesive layer 41 and only the plurality of abrasive grains 10 are uniformly arranged.

As the abrasive positioning means 80, it is possible to use a perforated plate or a mesh, and preferably made of a mesh having a mesh 81 as shown in Fig. 3 (a). The mesh 81 has a size according to the abrasive diameter, and may be manufactured by natural fibers or synthetic resins to facilitate its handling. In addition, when arranging abrasive grains, it is preferable to apply tension by holding the handle 82 to both sides so that the abrasive grains can be distributed and held on the binder layer 40. In addition, the abrasive grains 10 may be made of a mesh having a mesh 81 larger than the abrasive grain diameter and smaller than twice the abrasive grain diameter so that the abrasive grains 10 may be distributed in a uniform or uniform pattern. Figure 3 (b) shows a cross section through the I-I cutting line of the mesh shown in Figure 3 (a). Of course, the abrasive grain disposing means 80 is preferably removed after dispersing and disposing the abrasive grains.

The abrasive grains 10 generally refer to crystalline or polycrystalline materials having high hardness, but include diamond, cubic boron nitride (cBN), cemented carbide (WC), silicon carbide (SiC), titanium carbide (TiC), and alumina. it is preferably selected from the group consisting of (Al ₂ O _3). The plurality of abrasive grains 10 are preferably distributed in a uniform or constant pattern by the abrasive grain arrangement means (80).

When the arrangement of the abrasive grains is completed in this manner, as shown in FIG. 2 (f), the fluidized adhesive layer 41 is secondarily dried in the same manner as in the first drying. That is, the temperature of hot air 60 is made into about 300 degreeC-600 degreeC using an industrial dryer, and it divides several times at several intervals, and is dried. This secondary drying reduces the fluidity of the adhesive layer and allows the abrasives to be fixed on the binder layer.

Through the secondary drying step, the entire base material having a plurality of abrasive grains 10 uniformly disposed on the binder layer 40 is put in a drying oven and dried at about 100 ° C. Through this, after the binder material layer 40 is completely dried, the base material of an intermediate product state is charged in a furnace, and brazing is performed. The brazing may be performed in a reducing atmosphere such as a vacuum furnace or hydrogen furnace, or in an inert atmosphere using an inert gas such as nitrogen and argon. It is also desirable to include a step of maintaining at about 500 ° C. for 1 hour in the heat treatment temperature history curve to finally remove the residual binder completely.

Next, a method of manufacturing a polishing / cutting tool including a plurality of abrasive grains according to a second embodiment of the present invention will be described with reference to the process flow diagram of FIG. 4. In the process flow diagram of Figure 4, the step of preparing the base material (SS1), applying a paste layer of the binder (SS2), the first drying step (SS3) for drying the binder layer, on the surface of the dried binder layer Applying a liquid binder to (SS4), the step of installing the abrasive grains in the adhesive layer formed by the liquid binder (SS5), the step of dispersing and placing the abrasive grains by using the abrasive grains means (SS6), the abrasive Separation of the disposing means from the adhesive layer (SS7), and drying the flowable adhesive layer (SS8) is substantially the same as step S1 to step S8 of FIG. However, the difference is that after forming one layer of abrasive grains in which a plurality of abrasive grains are dispersed and arranged by steps SS1 to SS8, a step of forming a plurality of abrasive grain layers by repeating steps SS2 to SS8 as many times as desired is added. It is. After forming a plurality of abrasive grains in this way, the entire base material on which the plurality of abrasive grain layers are stacked is dried in an oven (SS9), and the entire base material is charged into a furnace and brazed (SS10). .

A second embodiment of the present invention will be described in more detail with reference to FIG. 5. In a state in which a single abrasive grain layer is formed through steps S1 to S8 of FIG. 1 (FIG. 5A), the binder material layer 50 in the form of a paste is provided. ) Is applied again (FIG. 5 (b)). Next, a primary drying step of drying the binder layer 50 is performed as shown in FIG. 5 (c). After that, a liquid binder is applied to the binder layer 50 as shown in FIG. The adhesive layer 51 may be formed. After arranging the abrasive grain disposing means 80 by applying tension to both ends of the adhesive layer 51 thus formed (FIG. 5 (e)), the abrasive grains 11 are evenly spread and dispersed. After arranging the second abrasive layer in this manner, the abrasive grain disposing means 80 is separated, and the adhesive layer 51 having fluidity is dried by drying with hot air 60 having a temperature of 300 to 600 ° C. as shown in FIG. By drying, a secondary drying process is performed. Thus, the arrangement of the abrasive grains formed in the second layer can be maintained without being disturbed in subsequent processes. If the desired abrasive layer is three layers, the above process can be repeated to form a third layer. After the final abrasive layer is formed, tertiary drying and brazing are performed in the same manner as in steps S9 and S10 of the first embodiment to complete the final product.

In particular, in the case of forming two or more abrasive layers, the paste binder formed after the second is applied with an appropriate thickness in consideration of the size of the abrasive grains disposed on the bottom abrasive layer and the size of the abrasive grains to be disposed thereon. desirable. In addition, in the case of manufacturing an abrasive / cutting tool including a plurality of abrasive grain layers as described above, when the abrasive grains of the surface abrasive grain layer can no longer work, the abrasive grains of the subsequent layer protrude and the work life of the tool does not end. Will be able to. It is preferable to use a Cu-based paste or an Ag-based paste having a lower hardness than the Ni-based paste having a high hardness as a paste binder used when forming a plurality of abrasive grain layers.

Through the method of manufacturing the grinding / cutting tool by the brazing method according to the present invention, it is possible to uniformly arrange the abrasive grains in a faster and easier manner without increasing the manufacturing cost. Furthermore, in the case of using a paste-type brazing binder, if the paste is not completely dried, when the product is loaded into a furnace and heated, the paste flows in the direction of gravity, causing defects such as thickness variation in the product. Although this occurs, the polishing / cutting tool manufacturing method of the present invention solves the above problems because it includes a step of drying the fluid paste in advance.

In addition, the present invention provides a metal brazing method (Metal Brazing Multi Layer) including a plurality of layers as well as a metal brazing (Metal Brazing Single Layer) in the manufacture of polishing / cutting tools by the brazing method, the surface layer Even if the abrasive grains of the can no longer continue to work is manufactured in a structure in which the subsequent abrasive grains can protrude so that the life of the tool can be continued without continuing.
