Embodiment Construction

[0018] A preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings. However, the scope of protection of the present invention is not limited to the following examples, that is, any simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the description are still within the scope of the patent of the present invention.

[0019] Such as figure 1 , 2 As shown, a multi-edged ultra-small-diameter drill includes a needle handle 1 and a needle body 2 arranged at one end of the needle handle. The end of the needle body away from the needle handle is a tip 3. Several helical chip removal grooves 4 are provided from the axis direction of the needle body to the tip, and several helical chip removal grooves are arranged at equal intervals and divide the tip into several identical sub-points; each row The cutting edge 5 is formed at the junction of the chip f...

Abstract

The invention discloses a multi-blade super-small-diameter drill point, comprising a point handle and a point body arranged at one end of the point handle, wherein one end, far away from the point handle, of the point body is a tip part, the surface of the point body is provided with a plurality of spiral chip grooves to the tip part along the axial direction of the point body, the plurality of spiral chip grooves are evenly spaced and divide the tip part into a plurality of identical branch tip parts, a cutting edge is formed at the junction of each chip groove and the corresponding branch tip part, each branch tip part is provided with a first rear cutter surface and a second rear cutter surface in sequence outside the side, far away from the corresponding chip groove, of the corresponding cutting edge, and a chisel edge is formed at the junction of the first and second rear cutter surfaces of every two adjacent branch tip parts. According to the multi-blade super-small-diameter drill point, each cutting edge is formed by the corresponding equant symmetric edges; different from the existing cutter machining mode, the drill point has the advantages that wear in a stainless steel machining process is favorably reduced, and the machining problems of point breakage, short service life, and the like during stainless steel drilling within the diameter range between 0.1mm and 0.5 mm can be solved.

Description

technical field [0001] The invention relates to a drill, in particular to a multi-edged ultra-small-diameter drill, which is mainly used for drilling and reaming stainless steel. Background technique [0002] As mobile phones continue to go high-end, stainless steel materials are widely used in mobile phones, such as shielding covers, shrapnel springs, support frames (injection molding), appearance parts, reinforcing steel sheets, stylus sleeves, and PIFA antennas Wait. At the same time, the integration of mobile phones is getting higher and higher, and the thickness is getting thinner and thinner. Therefore, the processing requirements for these stainless steel parts are getting smaller and smaller, and the processing difficulty is getting higher and higher. However, there is currently no Suitable special tools are used for processing, and the processing manufacturers still use the existing standard twist drills for processing. However, during the processing process, the n...
