Specific embodiment
Combined with specific embodiments below, the content of the utility model is described in further detail:
Fig. 1, Fig. 2 respectively illustrate the stereoscopic schematic diagram that drill mill has in the utility model, main view.Drill mill tool The hard alloy steel of material comprising shank section 1, cutting portion 2.Above-mentioned cutting portion 1 includes cutting edge 21.Cutting edge 21 is set to cutting The end in portion 2 is made of a plurality of helical form main cutting edge 211.The inner end of helical form main cutting edge 211 is at the end of cutting portion 2 The junction of portion center is integrated, and forms horn structure 212.Running through on cutting portion 2 has a plurality of helical form chip space 22.In spiral End cutting edge 221 is provided on the edge of shape chip space 22.The quantity of helical form chip space 22 and helical form main cutting edge 211 Quantity is consistent, and position corresponds.The helical angle of helical form main cutting edge 211 can be set to 20 °~40 °.Helical form master The flank of cutting edge 211 is made of the knife face of the different relief angles of section two, is indicated respectively with letter c and d on Fig. 3.It is above-mentioned Two relief angle c, d can be configured in 7 °~11 ° of section, and d > c.So, helical form main cutting edge 211 and by it Horn structure 212 made of junction makes drill mill tool realize Milling Function while boring, and helical form main cutting edge 211 Helical angle, relief angle are selected in a certain range, to reduce the vibratory output of drill mill tool at work, reduce the knife mark that quivers Quantity, so that the shaping surface precision of workpiece is higher, finish is more preferable.Preferably, the helical angle of helical form main cutting edge 211 is set 30 ° are set to, the relief angle of helical form main cutting edge is set as 9 °.
