BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing tip attached to a tool for polishing, drilling, or cutting a work piece, and a method for manufacturing the same, in particular, an ultra-abrasive preform capable of smoothly autogenous action and efficiently forming a homogeneous polishing material on a processing surface. It relates to a machining tip and a method of manufacturing the same.

Generally, processing tools used to grind, drill, or cut workpieces such as road concrete, asphalt, construction bricks, stone, etc., have a predetermined shape shank mounted on a rotating shaft of a power tool, and a work surface of the shank. It consists of an attached processing tip.

Particularly, the processing tip, which is a part for processing the workpiece, is manufactured by containing a hardened super abrasive, such as diamond or Cubic Boron Nitride (CBN), which has the largest hardness and wear resistance on the earth. In general, the cutting efficiency and cutting performance of the cutting powder are sensitively changed depending on the arrangement of the super abrasive material.

In order to distribute the diamond particles in the processing tip in a regular pattern, conventionally, as shown in FIG. 1, the diamond particles 121 are planarly arranged at regular intervals for each layer, and each layer of the processing tip 100 is disposed. The lamination method in the width direction W has been widely used.

However, the processing tip manufactured by the planar stacking method as described above has a layer in which the diamond particles are arranged and a layer in which the diamond particles are not arranged between the layers. There is a vulnerability in which diamond particles drop off prematurely.

In addition, in the case of a thick working tip, a large number of diamond particle groups should be stacked while going in the width direction, which causes uneconomical and low productivity. In this planar lamination method, when embedding superabrasive material on the processing tip, the particles should be arranged on the plane by forming overlap width within the particle diameter in the direction perpendicular to the processing surface, ie, perpendicular to the processing surface, for smooth autogenous action between the particles. do. At this time, it is difficult to apply the planar lamination method to the processing tools used for grinding and drilling, in which the machining surface is located on the circumference of the shank and the direction perpendicular to the machining surface is curved, so that the machining surface is located on the outer periphery of the shank. It is mainly used as a tip for cutting tools.

As a related art, Korean Patent Publication No. 4446981 (segment of cutting tool) is arranged diagonally with respect to the width direction of the processing tip, and is configured so that the height of the diamond grain group is lowered sequentially while going to the lower side, thereby improving cutting efficiency. A segment structure is disclosed that will provide high and consistent cutting performance.

However, the Patent No. 4446981 also has a disadvantage in that it is difficult to manufacture a thick working tip because it does not escape the limitation of using a method of laminating a diamond particle group for each layer.

Recently, a product that welds a processing tip to a shank by using a laser with high bonding strength and enhanced safety such as heat resistance instead of a joining method using silver lead having a relatively high risk of falling of the processing tip is widely used. At this time, in order to increase the cutting force of the bond according to the workpiece or processing conditions used, tungsten, tungsten carbide or abrasion resistance is added in order to add copper, tin, alloys thereof, or other organic or ceramic materials, or to increase the wear resistance of the bond. An abrasive is added to form a bond. However, since the bond is relatively inferior in weldability, it is made of a metal composition such as cobalt, iron, and nickel, which is excellent in weldability, but a blank layer free of diamond is formed in a predetermined width on the bottom of the processing tip. This is widely used.

In the planar lamination method, it is practically impossible to separately form the bond layer holding the diamond particles and the blank welded to the shank for each layer. Therefore, the bond layer is widely used as it is. In view of the melting point of the shank and the like, the material of the bond layer that can be used for welding using a heat source such as a laser is limited to a component having excellent weldability, and has a disadvantage in that it is restricted in use for various workpieces and processing conditions.

On the other hand, in order to increase the cutting performance of the processing tip, diamonds should be arranged as closely as possible so that the autogenous action of exposing the lower diamond grain group is exhausted before all the diamond grain groups constituting the processing surface are exhausted. Is an uneconomical aspect, as the concentration of diamond particles must be increased in all layers.

The present invention has been made to solve the problems of the prior art as described above, after preparing the pre-abrasive assembly in advance and sintered it in the processing tip body and the processing tip of the structure that can form a super abrasive grain group in various patterns and its It is an object to provide a manufacturing method.

In the said 2nd process, it is preferable to arrange | position the tip preform of a zigzag surface form along the longitudinal direction of the said molded object corresponding to a process direction.

Further, in the second step, it is preferable that the tip preform of the planar shape is placed upright on both side surfaces in the width direction of the molded body perpendicular to the processing surface.

Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

2 to 12 illustrate the manufacturing process of the processing tip according to a preferred embodiment of the present invention. As shown in Figures 2 to 12, the method for manufacturing a processing tip according to a preferred embodiment of the present invention after manufacturing the tip preform (Preform 10) to form a super abrasive grain group primarily, this tip preform (10) ) Is sintered together with the molded body 18 which provides the tool tip body.

First, FIG. 2 shows a tip preform 10 manufactured by depositing a superabrasive assembly on a base member 11. In the tip preform 10, the base member 11 is preferably composed of a fiber or a porous material in the sintering process, and is preferably provided in the form of a ribbon in consideration of the batch workability of the molded body 18.

As the porous material, carbon fiber, glass fiber, metal mesh, or other thermally degradable porous material may be adopted. Here, when carbon fiber or glass fiber is used, there is no shrinkage deformation during sintering, so that the volume and dimensions of the sintered body can be predicted, and sintered bonding between metal powders is possible between the fiber nets, and the specific surface area between the nets and the nets and bonds Bonding strength between them also has a good advantage. In addition, the metal mesh has the advantage that the shrinkage deformation during sintering is minimized and the bonding strength with the bond is good. On the other hand, when using a porous material capable of pyrolysis, there is an advantage that the porous material after sintering does not act as a barrier that prevents sintering bonding between bonds.

It is preferable that the diamond abrasive particles 13 are employed as the superabrasive material, but not limited to this example, other high hardness materials such as cubic boron nitride (CBN) may be employed. Hereinafter will be described with reference to the embodiment using diamond as a super abrasive material.

In FIG. 2, the protective film 12 formed on the upper surface of the base member 11 fixes the diamond particles 13 to the base member 11, and serves to impart predetermined mechanical strength to the tip preform 10. Preferably, it has a composition to which a metal bond and metal powder with good sintering bonding force are added as needed, such as a polymeric resin which can be thermally decomposed during a sintering process.

The protective film 12 is formed before or after the diamond particles 13 are disposed. In the former case, after the protective film 12 is formed on the upper surface of the base member 11, the diamond particles 13 are formed on the protective film 12 by a predetermined pattern or heated to a predetermined temperature to maintain a slurry. Dispersion and dispersing are performed in an irregular pattern. Then, the diamond particles 13 are compressed by a predetermined pressing plate (not shown), impregnated in the protective film 12, and then cooled and cured by the protective film 12. The tip preform 10 is manufactured. In the latter case, the diamond particles 13 are dispersed and disposed on the upper surface of the base member 11, and then a coating liquid containing a thermally decomposable polymer resin or the like is applied to impregnate the diamond particles 13, and then a protective film. The tip preform 10 may be manufactured by performing a process of hardening (12).

Preferably, the diamond particles 13 are impregnated in the protective film 12 in the form of a coating with a metal powder. In this case, since the spacing between the particles is adjusted according to the thickness of the metal powder coating layer 14, a separate mechanism for securing the space between the particles when arranging the diamond particles 13 is not required.

In manufacturing the tip preform 10, the diamond particles 13 may be disposed on both sides of the base member 11 and coated by the protective film 12, as shown in FIG. 3. In this case, the wear resistance can be increased by forming a regular pattern (or random) of diamond particles 13 on both surfaces or one surface of the base member 11 to increase the concentration.

In addition, the diamond particles 13 may be arranged in a stacked form in several layers while being supported by the plurality of base members 11 as shown in FIG. 4. In this case, each layer may be formed such that a regular pattern (or random) is adjacent to each other, or a regular pattern and a random distribution are alternated.

In addition, the diamond particles 13 may be arranged in a manner in which diamond particles 13 are stacked in a plurality of layers on a single base member 11 as shown in FIG. 5. In this case, the lamination is performed in a regular pattern or randomly, and the size of the particles may be uniform or distributed differently.

On the other hand, as an alternative to fixing the diamond particles 13 on the base member 11, a predetermined pressure-sensitive adhesive is applied to the upper surface of the base member 11 to prepare a base member 11 having an adhesive layer, and the base member ( 11) After placing the perforated net on the upper part of the perforated network, the diamond particles 13 are attached to the adhesive layer in a predetermined pattern, and after removing the perforated net, the metal powder is mixed with the polymer resin as necessary for thermal decomposition. It is also possible to manufacture the tip preform 10 by performing a process of applying a slurry and a process of curing the slurry.

The diamond aggregate 15 formed on the upper surface of the base member 11 may be distributed in a regular pattern as shown in FIG. 6, or may be distributed in an irregular pattern as shown in FIG. 7. Here, it is preferable that the horizontal or vertical distance (distance between particle centers) between diamond particle layers is set within the diameter of a particle | grain. When the diamond particles 13 are arranged in this manner, when the diamond particles 13 are arranged in a direction perpendicular to the processing surface of the processing tip described later, an overlap width corresponding to the diameter of the particles is formed between the diamond particles 13 so that any one layer may be formed. Before the diamond particles 13 are exhausted, the autogenous action of exposing the diamond particles 13 below may be smoothly performed.

After depositing the diamond aggregate 15 on the upper surface of the base member 11 to form the tip preform 10, the tip preform 10 is disposed on the molded body 18 that provides the processing tip body in a predetermined pattern and then sintered. The process is performed. In this case, the tip preform 10 is processed into various forms including a planar shape and then disposed on the molded body 18 and sintered.

FIG. 8 schematically illustrates a process of forming the tip preform 10 into a concave-convex shape in advance in order to sinter it into a substantially zigzag form in the forming body 18. As shown in the drawing, the planar tip preform 10 is interposed between a pair of uneven molds 16 and 17 capable of interfitting with each other, and then compressed to obtain a concave-shaped tip preform 10 'having a zigzag surface.

It is preferably composed of a polyhedron having a curved shape and having a structure divided into at least two parts in the width direction. The uneven tip preform 10 is disposed between the divided pieces 18a and 18b of the molded body 18 in a standing state, and the planar tip preform 10 is disposed at both sides in the width direction perpendicular to the processing surface to be described later.

It can be improved, and since the discharge of the cutting material can be made smoothly, there is an effect that can increase the life of the processing tip by minimizing the secondary wear phenomenon by the cutting. Here, as illustrated in FIG. 11, when the uneven tip preform 10 ′ is further disposed on the outer surfaces of the divided pieces 18a and 18b of the molded body 18, cutting efficiency may be further improved.

After disposing the tip preform 10 on the molded body 18 as described above, the sintering treatment is performed at a temperature of approximately 600 to 1200 ° C, more preferably 800 to 900 ° C, as shown in FIG. A process of forming the particle group 21 and the planar diamond particle groups 22 and 23 in the processing tip body portion 18 'is performed.

A jagged zigzag pattern group of irregular diamond particles 21 and planar diamond particle groups 22 and 23 formed at both edges in the width direction of the body portion 18 'are provided. Here, the concave-convex diamond particle group 21 sintered and formed in the body portion 18 'periodically has an inclined diamond array surface with respect to the width direction of the processing tip to maximize the occupying volume of the diamond particle 13 and process the same. It acts to facilitate the discharging of the chips during work. In addition, the planar diamond particle groups 22 and 23 sintered at both edges of the body portion 18 'have a function of reinforcing fast wear of both edges of the processing tip during the machining operation.
