Detailed description of the invention
As shown in Figures 1 to 5, a kind of Novel milling cutterhead, includes disk body 10 and a plurality of milling cutters 20 be installed on disk body 10 to the utility model, wherein:
This disk body 10 is provided with main shaft fixing hole 11 and a plurality of oblique through hole 12 in order to pour into a mould cutting fluid to cutting face, this plurality of oblique through hole 12 tilts to run through disk body 10 respectively, and incline direction E is counterclockwise, with contrary with disk body 10 rotation direction N; This oblique through hole 12 comprises the upper end hole 121 being positioned at disk body 10 upper surface, the lower stomidium 122 being positioned at disk body 10 lower surface and is positioned at the linear pattern passage 123 of disk body 10 inside connection upper end hole 121 and lower stomidium 122, is positioned at a plurality of upper end holes 121 of disk body 10 upper surface and is positioned at a plurality of lower stomidium 122 rounded distribution centered by main shaft fixing hole 11 respectively of disk body 10 lower surface.
This a plurality of milling cutter 20 is arranged on disk body 10 edge with the radial distance certain apart from main shaft fixing hole 11 center line, this a plurality of milling cutter 20 is followed successively by heavy-duty cutter 21 along disk body 10 rotation direction, middle milling cutter processing 22, mirror finish milling cutter 24, heavy-duty cutter 21, middle milling cutter processing 22 and mirror finish milling cutter 24, and, can according to actual conditions, between middle milling cutter processing 22 and mirror finish milling cutter 24, finishing cutter 23 is set, then a plurality of milling cutter 20 is followed successively by heavy-duty cutter 21 along disk body 10 rotation direction, middle milling cutter processing 22, finishing cutter 23, mirror finish milling cutter 24, heavy-duty cutter 21, middle milling cutter processing 22, finishing cutter 23 and mirror finish milling cutter 24.
The cutter body 201 that this milling cutter 20 comprises aluminum alloy material and the blade 202 be installed in cutter body 201, as shown in Figure 5, the cutter body 201 that aluminium alloy manufactures, body hardness can be reached after adding heat treatment (heat treatment HRC 38-40 degree), lightweight, can high rotating speed, high feeding, be applicable on high rotating speed equipment; Blade 202 material of each operation milling cutter 20 is as follows: the blade 202 of heavy-duty cutter 21 is wolfram steel material; The blade 202 of middle milling cutter processing 22 and finishing cutter 23 is PCD material; The blade 202 of mirror finish milling cutter 24 is monocrystalline diamond material.
