Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a chisel type micro drill bit, and more particularly to a method of regenerating a chisel type micro drill bit. 5 [Prior Art] Press, a micro drill bit generally used for drilling a hole on a printed circuit board, having a drill body and a drill handle integrally formed with the drill body portion for providing a drill by the drill handle portion The hole machine is clamped, and the drilled body portion (the outer right periphery is formed with the right dry cutting edge and the same number of chip flutes) performs the micro drill 10 hole operation of the printed circuit board. 15 However, because the outer diameter of the shank and the outer diameter of the drill body are quite large, the outer diameter of the shank is generally several times larger than the outer diameter of the drill body. Therefore, the body of the body (four) is When the micro-laid head is made, it is necessary to drop a large amount of material in the outer periphery of the body to meet the demand of fine-grained size. This will result in a waste of a large amount of material resources, not only the cost but also the environmental awareness of Weijin. The practice. The micro-drill bit made by the body molding is missing, and the inventor of the present invention is a "synthesis type micro-drill bit", such as the patent application of the Chinese patent No. #入于_^: Mainly, the small-diameter drill body can be separately fitted by means of fitting In the selection of the trough, the drill body is made to reduce the size of the 1 workmanship and then combined and used. Look for 4^. This type of micro-drill has a considerable degree of grinding. A phase injury, but need to be eliminated and discarded, although the 20 1305162 chisel micro drill has greatly reduced the required consumables during the manufacturing process, but the elimination and elimination of the elimination of the original material prices in the era of high prices, there are still doubts about wasting material resources presence. SUMMARY OF THE INVENTION In view of the above, it is a primary object of the present invention to provide a method for regenerating a chisel type micro drill bit, which is capable of remanufacturing a worn-in fitting miniature mold to regenerate a user. Accordingly, the present invention provides a method for regenerating a chisel type micro drill bit, comprising the steps of: (a): taking a chisel type micro drill bit having a drill handle member and a drill body member. One end of the shank member is formed with an axial fitting groove, and the drill body has a coaxial-integrated-first-and-connecting portion, and the connecting portion is tightly inserted at the end In the groove, and the first body portion has been worn to a predetermined extent; step (8): removing the first body portion; and step (e): cutting the outer diameter of the handle member and the connecting portion to a predetermined size; (d): forming a second drill body portion on the joint portion exposed outside the fitting groove, the second drill body portion having a plurality of cuts and grooves, and the cutting material is used for the circuit board Drilling, and the chip flute is used to provide the chip evacuation space during drilling. [Embodiment] In order to enable the Beckham Committee to have a better understanding and recognition of the features and features of the present invention, the following preferred embodiments are described below with reference to the following figures: 5 20 1305162 曰% with reference to the -to The fifth figure is a method for regenerating a chisel type micro drill bit provided by the preferred embodiment of the present invention, and the steps thereof include the following steps: Step (4): taking-loss to the pre-workability of the chisel type micro drill bit (10); As shown in the second figure, the chisel type micro drill bit (1) has a drill body member (I) and an i-shank member (12), and one end of the drill handle member (10) is axially formed with a fitting groove of a predetermined depth and width ( 121) The drill body (11) has a first body portion (in) and a connecting portion (1), and the first body portion (lu) and the connecting portion (1) 2) are integrally manufactured. The coaxial rod body, the connecting portion (112) is fixedly inserted into the fitting groove (121) with its free end tightly 0, so that the drill body member (11) and the shank member (12) are coaxially embedded. Coupling, a plurality of cutting knives and chip flutes are formed on the first body portion (111) for fine drilling of the printed circuit board and chip removal during drilling And the shank member (12) is used for clamping by a drilling machine; the first body portion (111) of the body member (11) has reached the elimination standard (about 15 thousand times has been performed) Drilling operation). Step (b): removing the first body portion (111) of the drill body member (u); as shown in the third figure, the first drill body portion (111) that has been worn out by means of tool cutting or grinding wheel grinding Remove it. Step (c): grinding or 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 diameter of the shank member (12) originally cut to 3.175 mm is cut to 2. 〇mm, and the diameter of the connecting portion (1 12) is cut to 1.0 mm. Step (d): forming a second drill body portion 1356162 (two 13) on the connecting portion (112), as shown in the fifth figure, forming a second drill on the exposed portion of the connecting portion (112) Body (10)), the second body (113) has a number of cutting tips:: shavings! The chip evacuation space when the hole is drilled by the chip flute in the operation of drilling by the cutter. = The above steps, you can replace the == type f-type drill bit, which has already reached the loss standard, and use the first-drilled body part that has been worn out, and then the iron handle piece and the connecting part are simply _ Diameter (reduction = direct service), and then re-formed on the joint of the small outer diameter - the second drill body with a number of cutting edges and chip flutes, so that the original material is re-manufactured with the least material - The cost of the embedded path of the small diameter: it is more in line with the environmental protection concept of today's reuse. 1305162 [Simplified description of the drawings] The first drawing is a flow chart of a preferred embodiment of the present invention. Drilling the invention - a preferred embodiment of the take-loss arbitrarily miniature type of invention - preferably complementing the removal of the first body portion
