New description: [New technical field] The creation department provides a kind of groove structure, especially the main groove of the drill bit located at the edge of the second paste knife. It is not parallel _ after the intersection, and then (4) the groove continues to extend around the drill groove in the direction of the drill body to increase the width of the chip flute, the thickness of the drill bit, assist the drill bit to quickly remove chips, and improve the overall structural strength. [Prior Art] According to the current design trend of electronic products, the electronic products are becoming smaller and smaller, so that the manufacturing of various electronic components inside electronic products will become more and more fine. In the electronic products, the printed circuit board body for which the electronic component group can be set is reduced, so in the printing road (four) process towel, A will use the micro drill bit to perform hole processing, and electronic components can be provided. The plurality of pins are inserted and then soldered to form an electrical connection. In addition, printed circuit boards, [C carrier boards, etc., in order to reduce the cost of production, will be processed simultaneously with multi-layered boards, because the two cutting edges of the drills on the market are mostly spiraled along the axial direction of the drill bit. The chip flutes, and the scraps cut by the cutter are discharged outward along the flutes, but the two flutes of the drill bit are arranged in a staggered spiral, so that the width of the flutes is limited and only It has a small width and affects the smoothness of the chip removal. If there is accumulation of chips between the chip flute and the hole wall, the chip will be blocked and the hole will be scraped between the bit and the hole wall. The surface of the wall is rough, and the spiral chip flutes on the drill bit will also reduce the thickness of the inner part of the drill bit, which will result in poor structural strength of the drill bit and accelerate the cutting tool when the bit rotates at high speed. Wear and damage, but also due to excessive friction resistance, the temperature rises rapidly, the cooling effect is not good, and the slag generated by the hot melt of the high temperature chip, and the slabs are not tightly combined to cause the copper protrusion phenomenon. So that the drill bit is prone to cracking

The groove and the auxiliary groove form a groove which is formed in a non-parallel relationship with the main row - and after the groove is grooved, the square body of the body of the body is continued to extend around the drill groove portion, and the width and elevation of the groove are not increased. The lake is fascinated, and most of the long hoes on the trough are surrounded by the slats, which can increase the internal cutting of the gullets and improve the structural strength of the drill bit and reduce the drill bit in the drilling industry. _Lifetime. 4 [Embodiment] The structure is as follows, and the method of wei _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Appearance and side view: Section: 2, respectively, is a partial enlargement of the view to the target A and a view of the direction of the cutting edge. The figure can clearly see the part η and the part 12, 1 (4). There is a drill body in the middle of the 5th drill bit 1 located on the side of the drill body 1 i Lu is extended outwards with the drill groove part 2 the other end of the object axis axis... the secret drill body 1 cut _13 side In the direction of the square: the drill groove portion 12 is located in the two-direction ring, and the main chip flute 1 = 'slot 15' is disposed, and the main chip flutes 14 and the sub-chip flutes 15 are different in pot setting, and the pair is provided. The flutes 15 extend around a predetermined length to form a non-parallel intersection with the main thin grooves 14 and form a groove point i 6 , and then the secondary flutes 15 have the same or different helix angles of the main chip. Continue to extend around the drill groove portion 1 2 toward the drill body. Furthermore, the drill 1 described above may be a drill or a micro drill of a type, such that the drill portion η may be of a straight __ (Un der CU 1 ) type and the like, and the drill groove portion 12 may be - The body is formed into a separate or separate structure, and the drill groove portion 位于 2 is located at the outer edge of the two cutter blades 3 respectively with a gap 131 recessed therein, and the depth of each gap 131 is preferably implemented as a drill bit 1 (four) 1 Between % and 4 (10), but in practical applications, 22 the groove portion 12 may not be provided with a gap 131, and the length of the groove portion 丄 chip groove 15 may be 8 =1' of the length of the chip flute 14 and The sub-lake trough 15 is extended to a predetermined length to form a sulcus point 16 with the main effervescent, and the small helix angle at the gully point 16 corresponds to the main sac, and the large spiral (four) should be swarf =15' and the helix angle (2) of the groove 15 at the groove point is formed to be larger than the helix angle (4) of the main groove 14 by -5° to 5〇. The angle between the settings - and the axial length of the drill tip 1 3 0 to the groove point 丄6 at the center of the knife 1 3 (1) between the slots 2 2 (10) ~ 75%; in addition, the secondary flute The angle of the helix 15 combined with the main row groove 14 at the gully point 16 can be changed, and the helix angle (θ 4) of the sub-groove 5 with the helix angle (^ $ ) intersecting the main flutes 14 In between: ~2◦. The angle is set to drill the groove. The structural design of the P1 2 can be increased by the secondary flutes i 5 extending around the drill groove 2 and not parallel with the main flutes 14 to increase the visibility and elevation of the troughs. The speed of chip removal, and because most of the length distance on the groove portion 12 has only the surrounding extension of the merged groove, the core thickness of the drill bit 1 inside the chip flute can be increased, and the drill groove portion i 2 can be raised. The overall structural strength of the drilled master 1 is such that during the drilling operation of the drill bit, the main discharge can be transmitted through the two different spiral angles of the drilled groove i 2 and the sub-row slot 1 5 is fast. Low waste plugs in the green Lai i 4 and the second row 4 measures 1 Cj & crack or fold 'and can effectively prevent the drill bit 1 from occurring during the drilling operation", J image, and ensure that the quality of the hole drilled is better I created this for the drill, which is located in the drill groove w red part 11 together with the screw groove ^__ slot 15 and the main row Ίς 1 direction is not parallel after the intersection, and then the auxiliary chip removal inserts and chips extend into the drill slot Part 12 is its main feature, borrowing the operation _^=, assisting the drill bit 1 to quickly discharge the effect, and quickly discharging the drilling ^ paste to reduce the waste shoulder Stacked and blocked in the main groove "the secondary chip flute 15", and because most of the long-term production on the drill-groove portion 12 has only the chip flutes that merge and extend around, the diameter of the drill bit 1 can be And improve the overall structural strength of the drill bit 1, which can effectively reduce the service life of the _1 in the Yijian transfer Wei Wei, get the long drill bit ί. Beben creative drill bit structure improvement in the actual make (four), for the following The advantages of the item are as follows: 卜) The copper 1 of the mine is located at the drill groove portion 12, and the main chip flutes 14 and the auxiliary flutes 15 having different spiral angles are arranged, and the auxiliary flutes and the main row are arranged.
