Field of the Invention The present invention relates to a tool surface strengthening treatment method, and more particularly to a surface strengthening treatment method for strengthening the surface of a cutting and drilling tool of the prior art. [Prior Art] With the rapid development of technology, various related consumer electronic products such as information and communication have become one of the fastest growing industries in the world, and among the aforementioned consumer electronic products, printed circuit boards (PCBs) are often provided. , Printed (10) B0ard), which can form a plurality of electronic circuits for electrically connecting the electronic components to each other, thereby achieving the effect of the conduction circuit. Wherein, the printed circuit board conducts the means of the different surface circuits, that is, the through holes are drilled through the surface between the surfaces, and the conductive holes are made of the electric ore, and in general, the through holes The drilling is done by PCB = 'When the drill bit is made and drilled, there will be residual or external stress on the surface of the drill bit (please refer to the tenth figure:: the tensile stress is generally the tensile stress) Not only will it attempt to stretch or stretch to cause surface defects such as tiny cracks, etc. [and also 兮pc/, fatigue strength', its service life is reduced, in view of this, fine powder and _ start powder, in 3: two 'Traditional tungsten carbide ^ ^u is brewed into a bar by powder metallurgy under the same pressure, and then it is placed on a special working machine with a diamond knife and a ^, and the machine is ground. The same / dish, enough to withstand the various stresses encountered in the use of the process, and is not easy to damage. 200817135, because of the high production costs, if the use of carbonized towns to produce, 'will lead to increased costs, so the industry More to substitute him or to defend Instead of using techniques, such as the use of metallurgical joining technology to join the handle part with stainless steel, titanium nitride treatment, plating and drilling, and ion implantation, but the pot is made in Bugu, There is a certain degree of difficulty, and it takes a considerable amount of time. For example, the aforementioned PCB drill bit, the current general cutting and drilling tools, the surface strengthening method is nothing more than cold working, heat treatment, in general, cold working is cutting, The surface of the drilling tool is continuously hit or rolled, so that it forms a poor row to increase the strength; the hot processing is to heat the cutting and drilling the king, and then to achieve the purpose of strengthening by means of quenching and tempering, however, The aforementioned surface strengthening treatment method is not only complicated in procedure, but also takes a long time. Later, the automobile industry unexpectedly discovered the bead blasting process during the research and testing on how to improve the service life of the valve spring, which is cold. A procedure, also known as "blasting," which was originally used for the descaling of mechanical parts or the grit blasting of gemstones. In the future, the bead blasting process is only limited to the surface treatment of automotive parts or the test of the aerospace industry. SUMMARY OF THE INVENTION The object of the present invention is to provide a method for surface strengthening treatment of a cutting and drilling tool, which is simple and convenient. And quickly strengthen the cutting and drilling tool surface of the prior art, and eliminate the residual stress in the cutting and drilling tools of the prior art, thereby improving the service life thereof. 6 200817135 The purpose of the invention is to cut and drill the tool table. The technical method used by the method to transport the 5$ chemical system is to further use the bead-cutting processing and the drilling and polishing ▲ to be used for the surface treatment of the cutting/cutting, that is, the cutting and drilling of the working surface and the ϊ, Eight of the table 'small beads (the beads can be steel balls, glass ginseng, ceramic beads, D steel particles of eight D faces or particles of any material with beads), so that the beads: uniform and dense impact The cutting and drilling tools "make:: material shell = plastic deformation to form a dense small round concave 胄; in each dent formation the same =, the material in each dent produces a dent from the center of the dent In the force of the scooping force and the outer edge of the indentation is not deformed, the force is generated to the center of the indentation i: the force of the two forces produces a compressive stress zone in the region. '' μ After this treatment for a period of time, the surface of the processed cut m and the money hole tool is covered with dents, thus forming a tight and compressed structure on the surface, and the external tensile stress remaining inside is also It can be gradually eliminated as the compressive stress zone is generated.
