Detailed description of the invention
As shown in Figures 1 to 5, a kind of Novel milling cutterhead, includes disk body 10 and is installed on a plurality of milling cutters 20 on disk body 10 in the present invention, wherein:
On this disk body 10, be provided with main shaft fixing hole 11 and a plurality of these a plurality of oblique through holes 12 tilt to run through respectively disk body 10 in order to the oblique through hole 12 to cutting face cast cutting fluid, incline direction E is counter clockwise direction, with contrary with disk body 10 rotation direction N; This oblique through hole 12 comprise be positioned at disk body 10 upper surfaces upper end hole 121, be positioned at the lower stomidium 122 of disk body 10 lower surfaces and be positioned at the inner linear pattern passage 123 that connects upper end holes 121 and lower stomidium 122 of disk body 10, be positioned at a plurality of upper end holes 121 of disk body 10 upper surfaces and be positioned at a plurality of lower stomidium 122 rounded distribution centered by main shaft fixing hole 11 respectively of disk body 10 lower surfaces.
These a plurality of milling cutters 20 are to be arranged on disk body 10 edges apart from the certain radial distance of main shaft fixing hole 11 center lines, these a plurality of milling cutters 20 are followed successively by heavy-duty cutter 21 along disk body 10 rotation directions, 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 be according to actual conditions, between middle milling cutter processing 22 and mirror finish milling cutter 24, finishing cutter 23 is set, a plurality of milling cutters 20 are followed successively by heavy-duty cutter 21 along disk body 10 rotation directions, 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.
This milling cutter 20 comprises the cutter body 201 of aluminum alloy material and is installed on the blade 202 in cutter body 201, as shown in Figure 5, the cutter body 201 that aluminium alloy is manufactured, after adding heat treatment (heat treatment HRC38-40 degree), can reach body hardness, lightweight, can high rotating speed, high feeding, be applicable on high rotating speed equipment; Blade 202 materials of each operation milling cutter 20 are 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.
In addition, above-mentioned milling cutter 20 can be plain milling cutter, face milling cutters, flying saucer milling cutter or circular peripheral-mill, and can coordinate multiple knife bar as: BT, SM, FMA, HSK or special plane use.
The principle of the invention is as follows: when facing cutter rotates, enter cutting fluid by stomidium 121 on oblique through hole 12, cutting fluid rushes between facing cutter and workpiece through passage 123 and lower stomidium 122, due to incline direction and the facing cutter direction of rotation of oblique through hole 12, when cutting fluid is gone out by each oblique through hole 12, form a kind of power that makes facing cutter entirety floating in facing cutter below, reduce facing cutter because of self gravitation and rotated the centrifugal force amplitude that main shaft glides relatively, simultaneously, cutting fluid is after oblique through hole 12 is gone out, between facing cutter and workpiece, form a cooling surface, reduce cutting temperature, in addition, on disk body 10, along its rotation direction, heavy-duty cutter 21 is installed successively, 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 make slightly, in, essence, minute surface four procedures, process at one time.
Design focal point of the present invention is, by a plurality of and oblique through hole disk body direction of rotation is set on disk body, in facing cutter rotation process, the cutting fluid of being gone out by a plurality of oblique through holes, formation makes the buoyancy of facing cutter entirety floating, for overcome facing cutter because of self gravitation and centrifugal force relatively main shaft downslide phenomenon played effective containment effect, improve the security of machine tooling, simultaneously, also avoid facing cutter to glide and caused the phenomenon of workpiece and cutter damage to occur, the machining accuracy that has ensured workpiece, has improved product percent of pass.
The above, it is only preferred embodiment of the present invention, not technical scope of the present invention is imposed any restrictions, therefore every foundation technical spirit of the present invention is to any trickle amendment made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
