Description of the Invention (/) The present invention is a diamond trimmer and its manufacturing method, which is based on the δχ of a metal handle and an assembly hole, and the diamond is brazed. A diamond trimmer is formed on a metal assembly rod 'and inserting the metal assembly rod into the assembly hole of the metal handle grip'. Grinding wheels are the most popular machining tools and can be used to grind a variety of workpieces and products. Grinding wheels contain many abrasive particles (such as diamond, cubic boron nitride, carbonized carbide or alumina). These abrasive particles are embedded in the base material of the grinding wheel. The substrate is usually ceramic or glass, but it can also be metal or resin. When grinding a workpiece with a grinding wheel, the abrasive particles must first be protruded in order to penetrate the workpiece and generate abrasive debris. The abrasive particles of the new diamond grinding wheel are buried in the substrate and must be “edged” with a diamond dresser before the abrasive particles can remove the workpiece. After grinding for any period of time, the protruding part of the grinding wheel is gradually dulled, so the friction resistance is gradually increased. What's more, the more the substrate is closer to the workpiece, the more difficult it is to remove abrasive debris, but it is packed between the abrasive particles, making it more difficult for the abrasive particles to protrude. Such a vicious cycle will greatly reduce the grinding efficiency of the grinding wheel, and even cause the workpiece to overheat and burn tissue. Therefore, when using a grinding wheel, the abrasive particles must be “dressed” with a diamond trimmer every so often. If the shape of the grinding wheel deviates from the true circle, it can also be trimmed to “Truing”. The tip of a diamond trimmer is a diamond (can be single crystal or polycrystalline). This diamond can be “sharpened” or “skinned” into the wheel. The traditional diamond trimming structure is shown in the fifth figure i (80) is set at the end of a metal handle grip (90): 糸 = In order to make the diamond (80) located at the end more prominent, The diamond (80) at the end of the metal handle grip (90) is cut into a sharp cone shape.

There is a fixing screw hole (丄 4) penetrating into the assembly hole (1 2); the outer diameter of the metal assembly rod (20) is matched with the aforementioned assembly hole (1 2), and the assembly hole (1 2) can be assembled ), A diamond (24) is bonded to the end of the metal assembly rod (20); when assembling, the metal assembly rod (20) is assembled into the assembly hole (1 2) of the metal handle grip (10). ·) And screwing a fixing screw (30) into the fixing screw hole (14) to firmly fix the metal assembly rod (20), and the metal assembly rod (20) and the metal handle grip (1 0) The combination is firmly combined into one body, so that the diamond knife assembling operation of the present invention is completed.

Viewing from the third figure, it is an exploded view of another preferred embodiment of the present invention. It can be seen that an assembly hole (1 2 ′) is provided at the end of the metal handle grip (1 0,). ), A diamond (2 4 ') is fixed at the end of the metal assembly rod (20,), but the outer diameter of the metal assembly rod (20) is slightly smaller than the inner diameter of the assembly hole (12'). Large; when assembling, first heat the metal handle grip (10 ′) to make its assembly hole (12 ′) expand its diameter due to high temperature.

Description of the invention (Even) Likou · ,, and, to an appropriate degree, the secret of Group I (2q,) will be assembled into the group ^ hole (12, ), After the metal handle grip (10,) cools down, the gold 1 assembly rod (20 ') is set by the stable clamp in the assembly hole (12,) of the metal handle grip (1); When replacing the metal assembly rod (), increase the metal handle grip (work 0,) again to expand the assembly hole (1 2,) for replacement. From the fourth picture, it is the group of the embodiment shown in the third diagram: a schematic cross-sectional view, in which the metal assembly rod (20,) and the metal handle grip (10) shrink due to thermal expansion. The function of the united body is the same as that of the united body. The manufacturing method of the present invention is mainly a combination of the method of drilling hard cymbals and a metal assembly rod (20, type), which can provide excellent bonding effects. The diamond repair knife manufactured by the manufacturing method of the present invention has another great advantage: The diamond trimming diamond only uses the sharp corner of the outer end. After the diamond is blunt, it will not be used again. Therefore, cheap diamonds with smaller particles can be used. However, traditional diamond trimming uses mechanical combination to hold the diamond. Its adhesion is not strong, so we have to use diamonds with larger particles to increase the density of diamonds and avoid threshing. The present invention uses rhenium alloy solder to firmly hold diamonds with chemical bonds, so there is no need to use larger particles. Diamonds. The price of diamonds rises sharply with the size = large, using small particles of artificial diamonds (such as 20/2 5 divisions' 130 per carat, the particle size < lmm) & large natural particles Diamonds (such as 1/3 carats) have a much lower cost. Because the solder used in the manufacturing method of the present invention can hold diamonds firmly, 7 paper sizes are applicable to China National Standard (CNS) A4 (21,297 mm) 509609 A7 B7 V. Hair It is clearly stated that the diamond can be more prominent without falling off. In particular, the method of the present invention can provide a stable bonding effect of the diamond (2 4, 2 4,), so the metal handle grip (10, 10,) end The angle of the part can be small, so it will not block the worker's line of sight, so that the diamond (24, 24 ') can be aligned with the protruding part of the grinding wheel for effective dressing. Over-plated metals that can form carbides, such as 1% titanium or chromium. Because diamonds are easily damaged at high temperatures, the melting point of the solder should not exceed the workmanship. 0. When performing brazing, 'powder the powder The solder particles are glued and coated on the leading edge of the metal assembly rod, and then the diamond with the upward tip is pressed into the solder from the bottom. If the material is sheet-like, you can place a small piece on the upper end of the metal assembly rod, and then place the tip upward. The diamond is above the soldering pad. The above metal assembly rods can be arranged neatly (such as placed in the slot of the frame) and placed in a vacuum furnace. When the furnace temperature exceeds the melting point of the material, the solder is about to weld the diamond. 丨 乂 2 0 / 2 5 MBS ~ 95G (American Kiwi Manufacture) = make the diamond repair knife of the present invention.
