M412822 五、新型說明: 【新型所屬之技術領域】 本創作係提供-種_之制槽結構奸,尤指鑽頭之 鑽槽部位於二糊刀關邊處所環設之主制觀副排屬槽 呈不平行_交後,再㈣槽朝鑽身部方向繼續環繞延 伸於鑽槽部處’藉以增加排屑槽寬度、鑽頭心厚,輔助鑽頭 快速排屑,並提昇整體的結構強度者。 【先前技術】 按,現今電子產品為朝向_:短小的設計趨勢下,使得 各種電子產品對於體積要求變得更小,因此電子產品内部各 種電子元件的製造加工將變得越來越精細,並使電子產品中 可供電子元件組設定位之印職路板體赫必織之縮小, 所以在印職路㈣製程巾,A多會利_戦微型鑽頭來 進行孔洞加工,而可提供電子元件的複數接腳穿插後再予以 焊固形成電性連接。 再者,印刷電路板、:[C載板等為了降低生產的成本, 均會採用多層疊板同時加工,由於目前市面上鑽頭的二刀刃 大多是沿著鑽頭軸向為環設有呈螺旋狀之排屑槽,並將刀刀 切則的廢屑沿著排屑槽向外排出,但因鑽頭之二排屑槽為呈 現交錯式螺旋環繞,以致使排屑槽寬度便會受到限制而僅具 有較小的寬度,並影響排屑的順暢度,倘若鑽頭排屑槽與孔 壁間有堆積切屑的情況發生,將導致切屑阻塞於鑽頭與孔壁 3 财12822 之間相互刮擦,使孔壁表面粗糙,且因鑽頭上所環設之螺旋 狀排屑槽亦將造成鑽頭内部的心厚大幅縮減,而導致鑽頭整 體的結構強度變差,並在鑽頭高速旋轉時便會加速切削刀刀 之磨耗與損傷,同時亦會因磨擦阻力過大所導致其溫度快速 上升、冷卻的效果不佳,加上高溫切屑熱融所產生之膠渣, 以及夕層疊板未密合造成銅突現象,則使鑽頭容易產生崩裂M412822 V. 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
