Abstract
The present invention provides a manufacturing method for regenerating an embedded microbit, which includes the following procedures: procedure (a): an embedded microbit is taken; the embedded microbit is provided with a drill handle and a drill body and one end of the drill handle is provided with an axial embedded slot; the drill body is provided with a first drill body part and a connecting part which are connected into one coaxially, one end of the connecting part is tightly and fixedly inserted in the embedded slot and the first drill body part is destroyed to a prearranged extent; procedure (b): the first drill body part is eliminated; procedure (c): the diameter of the drill handle and the connecting part is cut to a prearranged size; procedure (d): a second drill body part with a plurality of cutting blades and chip grooves is formed on the connecting part. Therefore, the destroyed embedded microbit is remanufactured into an embedded microbit with small diameter for regenerative use.
Description
Technical field
The present invention is relevant with tabled micro drill, the more detailed regeneration manufacturing method that is meant a kind of tabled micro drill.
Background technology
Press, generally be used to the microbit of holing on the printed circuit board (PCB), has a drill body part and one and the integrally formed drill shank of this drill body part, with by this drill shank for a drilling machine clamping, and carry out the trickle bore operation of printed circuit board (PCB) by this drill body part (being formed with some cutting edges and equal number chip area on its periphery).
Only, since the outside dimension drop of the external diameter of drill shank and drill body part suitable greatly, the external diameter that is generally drill shank is greater than more than the external diameter several times of drill body part, when therefore making this microbit in integrated mode, the demand that must after machining away wide variety of materials on the periphery of drill body part, can meet fine dimension, but thus, certainly will cause the waste of lot of materials resource, not only cost is higher and also against the practice of paying attention to now under the environmental consciousness.
In response to the above-mentioned one-body molded microbit shortcoming of making, the inventor had developed a kind of " tabled micro drill " in before, as No. the 95213974th, TaiWan, China patent application, it mainly is that brill body spare with a minor diameter is embedded in the embeded slot of a large diameter drillstock spare in chimeric mode, make and bore body spare and drillstock spare and can go ahead of the rest and combined again after selecting corresponding suitable outside dimension manufacturing respectively for use, to reduce the material of required waste; Yet, this kind tabled micro drill is after use to a certain degree (is generally and carries out bore operation 10,000 times), its drill body part is having the abrasion and the damage of certain degree, and need to be eliminated discarded, though tabled micro drill is the required consumptive material of a large amount of minimizings when making, but loss and discarded eliminating for former surging epoch of material price now still has the doubt of waste material resource to exist.
Summary of the invention
In view of this, main purpose of the present invention is the regeneration manufacturing method that is to provide a kind of tabled micro drill, is the tabled micro drill of loss to be made and the use of regenerating again.
Edge this, the present invention is the regeneration manufacturing method that a kind of tabled micro drill is provided, and it is characterized in that, includes following steps:
Step (a): get a tabled micro drill, this tabled micro drill has a drillstock spare and and bores body spare, one end of this drillstock spare is formed with an axial embeded slot, this brill body spare has one first drill body part and a junction that is coaxial one connection, this connecting portion is to be inserted in this embeded slot so that the one end is fastening, and this first drill body part has been lost to a predetermined extent;
Step (b): remove first drill body part;
Step (c): external diameter to a preliminary dimension of cutting this drillstock spare and this connecting portion;
Step (d): form one second drill body part on this connecting portion, this second drill body part has some cutting edges and chip area, and this cutting edge is to be used to hole on the circuit board, and this chip area is in order to the chip removal space in when boring to be provided.
Its first drill body part in step (a) has carried out bore operation 10,000 times approximately, and reaches the standard that loss is eliminated.
It is this connecting portion to be exposed on the position outside this embeded slot form this second drill body part in step (d).
Description of drawings
Further understand and approval for the auditor can be had feature of the present invention and characteristics, below enumerate preferred embodiment and conjunction with figs. is described as follows, wherein:

Fig. 3 is the schematic diagram of a preferred embodiment of the present invention when removing first drill body part;
Fig. 4 is that a preferred embodiment of the present invention is in the schematic diagram that the external diameter of drillstock spare and connecting portion is cut to a predetermined outer diameter size respectively;
Fig. 5 is a preferred embodiment of the present invention forms second drill body part on connecting portion a schematic diagram.
The specific embodiment
Please cooperate and consult Fig. 1 to Fig. 5, be the regeneration manufacturing method of a kind of tabled micro drill that a preferred embodiment of the present invention provides, and its step comprises as follows:
Step (a): get a tabled micro drill 10 that is lost to predetermined extent; As shown in Figure 2, this tabled micro drill 10 has one and bores a body spare 11 and a drillstock spare 12, this drillstock spare 12 1 ends axially are formed with the embeded slot 121 of a desired depth and width, this brill body spare 11 has one first drill body part 111 and a junction 112, this first drill body part 111 is the coaxial bodies of rod that form for integrally manufactured with this connecting portion 112, this connecting portion 112 is to be inserted in this embeded slot 121 so that its free end is fastening, make this brill body spare 11 and this drillstock spare 12 be coaxial chimeric the connection, be formed with some cutting edges and chip area on this first drill body part 111, chip removal operation during with the trickle boring of carrying out printed circuit board (PCB) and boring, this drillstock spare 12 are then with for a drilling machine clamping; First drill body part 111 of this brill body spare 11 reaches loss culling level (having carried out 10,000 times bore operation approximately).
Step (b): remove first drill body part 111 that bores body spare 11; As shown in Figure 3, utilize the mode of Tool in Cutting or abrasion wheel grinding will be first drill body part 111 of loss removed.
Step (c): the external diameter of this drillstock spare 12 and connecting portion 112 external diameters of this brill body spare 11 are ground or be cut to a predetermined outside dimension respectively; As shown in Figure 4, this drillstock spare 12 diameter 3.175mm originally is cut to 2.0mm, the diameter of connecting portion 112 then is cut to 1.0mm.
Step (d): on this connecting portion 112, form one second drill body part 113; As shown in Figure 5, form one second drill body part 113 on the position that this connecting portion 112 exposes, this second drill body part 113 has some cutting edges and chip area, and the chip removal space in when boring is provided by this chip area with the operation of being holed by this cutting edge.
By above-mentioned step, can will reach loss standard originally and need to eliminate the tabled micro drill that abandons, utilize first drill body part of loss to remove, again drillstock spare and connecting portion are cut to predetermined external diameter (diameter of reduction) again, on the connecting portion of little external diameter, form second drill body part with some cutting edges and chip area more again, the tabled micro drill that to originally desire to eliminate is being removed under the minimal material, again the chimeric microbit that produces a path is for use, can not only meet the environmental protection notion of utilizing again now and more can reduce expenditure on the manufacturing cost.
