The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the six face flat-end cutters provided in the example of the utility model 1;
Fig. 2 is the structural schematic diagram at milling cutter point of a knife position in the example of the utility model 1.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.
Example 1
Referring to Fig. 1 and Fig. 2 which shows the structure of six face flat-end cutters of the high-strength, antioxidant provided in this example is shown It is intended to.
As seen from the figure, which includes mainly 200 two parts of handle of a knife 100 and blade.In order to improve intensity, knife Handle 100 and blade 200 are all full wolfram steel structure, and the two, which is integrally formed, constitutes six face flat-end cutters.Six face tack of such structure The outer diameter of milling cutter be 0.6mm~2.0mm, be specifically as follows 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm etc..
200 one end of blade is connect with handle of a knife 100 in the six faces flat-end cutter, is set on the other end there are six cutting face 300.Such as Shown in Fig. 2, two main cutting faces in six cutting faces 300, respectively two the first symmetrical main cutting faces 310 and second Main cutting face 320, there are four secondary cutting face, 330 and second secondary cutting face 340 of the respectively symmetrical first secondary cutting face with And symmetrical third pair cutting face 350 and fourth officer cutting face 360.
Wherein, the first secondary cutting face 330 is located at 310 side of the first main cutting face, and it is secondary that third pair cutting face 350 is located at first 330 side of cutting face, the second main cutting face 320 are located at 350 side of third pair cutting face, and the second secondary cutting face 340 is located at second 320 side of main cutting face, fourth officer cutting face 360 are located at 340 side of the second secondary cutting face.
In addition, it is poor to be also designed with three-dimensional position between every group of cutting face, so that the application it is very fast in positioning and Standard greatly improves machining accuracy and processing efficiency.
A pair of of debris groove 400 is additionally provided on blade 200, debris groove 400 can be used for chip removal.Spiral is arranged Consider to be worth doing groove 400 helical angle be specially 20 °~30 °, be specifically as follows 21 °, 22 °, 23 °, 24 °, 25 °, 26 °, 27 °, 28 °, 29 °, 30 ° etc.;And flute length be 6.0mm~10.0mm, be specifically as follows 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, 8.5mm, 9.0mm, 9.5mm, 10.0mm etc.;And remaining heart thickness is 0.05mm~0.15mm after the fluting of blade 200.
This example passes through the helical angle to 200 rational heart thickness increments of blade, 200 debris groove 400 of blade as a result, It is arranged and the setting of 200 flute length of blade has also taken into account rigid requirements while ensure that 200 chip resistance of blade is good.
In addition, this example approach is learnt by many experiments, and when residue heart thickness is 0.10mm after blade 200 is slotted, blade 200 performance is best.
For the six micro- milling cutters of face forward type of the structure, this example also further coats one layer of chromium titanium aluminium nitrogen on its surface and mixes Miscellaneous carbon protective layer.The chromium titanium aluminium nitrogen-doped carbon protective layer is stratiform ball adding shape nanocrystalline structure, and forms self-lubricating surface layer.
Thus the chromium titanium aluminium nitrogen-doped carbon protective layer hardness constituted is high, has good attrition resistance, and can be in high temperature process It forms aluminium oxide anti oxidation layer in the process and improves high temperature process service life of cutter;In addition, this chromium titanium aluminium nitrogen-doped carbon protective layer Self lubricity it is good, anti-seizure performance is very high, can ensure the smooth discharge of chip during the cutting process and increase longevity of milling cutter Life.
For this example in specific implementation, the protective layer overlay area of the six faces forward type milling cutter is the side of milling cutter, preferably From blade tip to 10~25mm length areas of handle of a knife shank.Specially be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm etc..
And the thickness of the chromium titanium aluminium nitrogen-doped carbon protective layer covered on the protective layer overlay area is uniform, thickness is 0.5 Between~2 μm, preferred coatings thickness is 1~2 μm here.
In this way, implementation through the above scheme and multiple authentication, the machining accuracy higher for the milling cutter that this example provides, service life Longer, processing efficiency higher, and stability lower to machine power demand are more preferable, especially higher blind in precision and rigid requirements In fishing, performed better than than unprotected same type milling cutter.
Example 2
The basic structure for the six face flat-end cutters that this example provides is identical as example 1, is not repeated here herein.Difference It is, the plan of establishment of chromium titanium aluminium nitrogen-doped carbon protective layer is different from example 1 in this example.
In this example, the chromium titanium aluminium nitrogen-doped carbon protective layer being arranged in cutter body is using non-even thick scheme, thickness Change between 0.5~2 μm, and along blade tip to handle of a knife shank.
Specifically, in this example the thickness for the chromium titanium aluminium nitrogen-doped carbon protective layer being arranged positioned at blade tip be 1.8-2 μ M μm, specially 1.8 μm, 1.9 μm, 2.0 μm etc.;It is even in the chromium titanium aluminium nitrogen-doped carbon protective layer thickness being arranged on blade Thickness, thickness between 1.0-1.8 μm, specially 1.0 μm, 1.1 μm, 1.2 μm, 1.3 μm, 1.4 μm, 1.5 μm, 1.6 μm, 1.7 μm, 1.8 μm etc.;At shank section be arranged chromium titanium aluminium nitrogen-doped carbon protective layer thickness be even thickness, thickness 0.5-1.0 μm it Between, it is specifically as follows 0.5 μm, 0.6 μm, 0.7 μm, 0.8 μm, 0.9 μm, 1.0 μm etc..
Thus six face flat-end cutters may make to remain best performance in use.
Example 3
This example approach proposes on the basis of 2 scheme of example.This example is mixed in the chromium titanium aluminium nitrogen being arranged on blade Miscellaneous carbon protective layer uses non-even thickness, and specially gradually thinning by thickness along fluting direction from blade tip, i.e., thickness is along fluting direction 1.0 μm are faded to by 1.8 μm.
Thus six face flat-end cutters may make to remain best performance in use.
