For example, = a large amount of material resources will be caused, which is not only costly but also retroactive. The practice of consciousness. ^The above-mentioned body-formed micro-drill is missing. The inventor has developed a Φ-type "chimeric micro-drill, such as 95213974, which is mainly used to embed a brother J-moon brother in a large-diameter shank.侔1, the diameter of the drill body in the fitting method of the dare to fit the groove, so that the drill body and the shank corresponding to the appropriate outer diameter size are manufactured and then combined to use the material; however After the fascinating micro-drill has been carried out for 10,000 times, the drilled field has 1 loss and damage, but it needs to be eliminated and discarded. Although 20 200840677 smashed micro-drill has reduced the required consumables during manufacturing. However, in the era of high raw material prices, there are still doubts about wasting material waste. 5 [Invention] In view of this, the main object of the present invention is to provide a remanufactured manufacturing of a chisel type micro drill. The method can remanufacture the lost chisel micro drill bit to regenerate the user. Accordingly, the present invention provides a method for remanufacturing a chisel type micro drill bit, including the following Step: Step (a): taking a chisel type micro drill bit having a drill handle member and a drill body member, one end of the drill handle member forming an axial fitting groove, the drill body member having One of the first body portion and a connecting portion are integrally connected coaxially, and the connecting portion is inserted into the kneading groove with one end of the fastening portion b, and the first body portion has been worn out to a predetermined range of 5 degrees. , step (b): removing the first body portion; step (6): cutting the outer diameter of the handle member and the = connecting portion to the size of the thief; and step (4) is formed on the connecting portion exposed to the outer portion a second drill body having a right-handed cutting edge and a chip flute for performing a buckle drilling on the circuit board, and the chip flute is for providing a drill [Embodiment] In order to enable the Beckham Committee to have a better understanding of the features and characteristics of the present invention, the following preferred embodiments are listed with reference to the figure 5 200840677 Referring to the first to fifth figures, a reciprocating manufacturing of a chimeric micro-system is provided in a preferred embodiment of the present invention. Green, the steps include the following: Step (8): Take-to-loss to the chiseled micro drill bit (1〇); 5 As shown in the second figure, the fitted micro drill bit (1〇) has a drill piece (1 〇) And a shank member (10) that is formed with a fitting groove (121) having a predetermined depth and width, the body member (11) having a first body portion (111). a connecting portion (1) 2), the first body portion (ill) and the connecting portion (1) 2) are integrally manufactured coaxial rod bodies, and the connecting portion (112) is fixedly inserted by the free end thereof In the fitting groove (121), the drilling body (11) is coaxially coupled with the shank member (12), and the first drilling body portion (111) is formed with a plurality of cutting edges and chip discharges. a slot for fine drilling of the printed circuit board and chip removal during drilling, and the handle member (12) is for holding by a drilling machine; the first part of the body (11) The drill body (111) has reached the depletion standard (about 10,000 drilling operations have been carried out). #步(b): Remove the first body portion (111) of the drill body (11); as shown in the third figure, the first drill body portion that has been worn out by means of tool cutting or grinding wheel grinding (111) ) to remove. Step (C): grinding and cutting the outer diameter of the shank member (12) and the outer diameter of the connecting portion 20 (112) of the drill body member (U) to a predetermined outer diameter dimension; As shown, in the present embodiment, the original diameter of the shank member (12) is cut to 2.0 mm, and the diameter of the connecting portion (112) is cut to 1.0 mm. Step (d): forming a second body portion 6 on the connecting portion (112), as shown in the figure of 200840677 nr, forming a body portion (113) on the exposed portion of the connecting portion (ι2) The second body portion (113) has a plurality of cutting holes and chip flutes for drilling the cutting tool to provide a chip evacuation space for drilling when the chip is grooved. 5 With the above steps, the original has been lost and needs to be eliminated.
