Description of drawings
Fig. 1 is the schematic end of the instrument that engages with cylinder body according to first embodiment of the invention.
Fig. 2 is the schematic elevational view of the instrument that engages with the cylinder body of Fig. 1.
Fig. 3 a and 3b are when the amplification view that is being parallel to and is passing the outer surface of cylinder body among the circle A of Fig. 2 when observing in the sectional plane of longitudinal axis of main body.
The specific embodiment
Fig. 1 and 2 has schematically described one embodiment of the present of invention.Preferably by 316 or the basic main body 1 for cylinder made of the stainless steel of 316L level around its longitudinal axis 2 with the speed rotation (in arrow 3 indicated directions) in about 20-200 rev/min of scope.The rotation of main body 1 can realize in the machine with rotating shaft such as lathe.
The best instrument of making by the tungsten carbide that is coated with titanium nitride or titanium carbonitride 4, tangentially is introduced the cylindrical outer surface 8 of main body 1, arrive the degree of depth that common scope is the 20-200 micron, and on the direction 5 and be parallel to longitudinal axis 2 and move axially with the fixedly feed rate in the scope of 20-200 micron/commentaries on classics with respect to main body 1.
When instrument 4 is introduced into the outer surface 8 of main body 1, the angle of instrument 4 engages with main body 1, makes tool surfaces 22 be provided with respect to the outer surface 8 angled 6 of main body 1, is approximately 24 degree.
The groove 23 that instrument 4 has caused the spirality of one-tenth asymmetrical form (when measuring in the cross section that is being parallel to longitudinal axis 2) to be provided with respect to the axially-movable of rotating main body 1, this groove has interarea 9 and the secondary face 10 that forms on outer surface 8.Interarea 9 also is angle 6 with longitudinal axis 2, approximately is 24 degree in this embodiment.
Helically disposed groove 23 has pitch 21, and this pitch equals the axial feed speed of instrument 4 with respect to main body 1.Found that this is favourable: the scope of this axial feed speed is 20-200 micron/commentaries on classics, and therefore the axial pitch 21 of helically disposed groove 23 also is the scope of 20-200 micron, so that produce best orientation-dependent reflection characteristic on the outer surface 8 of main body 1.
When observing in the cross section shown in Fig. 3 a and 3b, helically disposed groove 23 appears to asymmetric zigzag.
In order to ensure when instrument 4 engages with main body 1, from main body 1, not removing material, with oil emulsion, the extreme pressure type is synthetic or form mineral oil provides proper lubrication oil.During groove 23 forms, between the outer surface 8 of tool surfaces 22 and main body 1, kept certain hydrodynamic lubrication level ideally, be possible therefore with the minimise wear on the tool surfaces 22 of instrument 4.The use of lubricating oil has guaranteed to form in level and smooth and coherent mode the interarea 9 of groove 23, and the wearing and tearing minimum on the tool surfaces 22.
When observing in the cross section of the longitudinal axis 2 that is being parallel to main body 1, because groove 23 is asymmetric, this has guaranteed that the electromagnetic radiation of reflecting from electromagnetic radiation source 12 and 17 is orientation-dependent thereon.With reference to figure 3a, as indicated by arrow 13 from the electromagnetic radiation that electromagnetic radiation source 12 sends, inject interarea 9 with respect to line 30 with angle 16, and reflect back towards electromagnetic radiation detector 15, as shown in arrow 14.Yet, with reference to figure 3b, the electromagnetic radiation of sending from electromagnetic radiation source 17, as shown in arrow 18, inject interarea 9 with respect to line 30 with same angle 16 perpendicular to longitudinal axis 2, and reflect in the opposite direction away from line 30 (normal of longitudinal axis 2 just),, thereby can not detected by electromagnetic radiation detector 15 by arrow 19 expressions.
In two examples, when electromagnetic radiation detector 15 being set surveying from electromagnetic radiation that same pip 20 is propagated perpendicular to the longitudinal axis 2 of main body, detection is depended on the position (just, radiation source 12 or radiation source 17) of electromagnetic radiation source and the angle of interarea 9 from the ability of the electromagnetic radiation of interarea 9 reflections.
Be appreciated that the formation that an importance of the present invention is a groove 23 does not need to remove material, and the formation effect of instrument 4 on main body 1 is similar to polishing, pressurization glazing or rubbing action.In Fig. 3 a and 3b, the outer surface 8 before groove 23 forms is shown as chain-dotted line 11, and this chain-dotted line roughly is located at the position of the average radial degree of depth between the tip 24 of groove 23 and the root 25.
Though in the above-described embodiments, angle 6 between instrument 4 and main body 1 keeps being roughly 24 degree, but be appreciated that angle 6 can be some other angles in other embodiment that does not have to show, it depends on the needed orientation-dependent reflection characteristic of concrete application.
In the embodiment that another does not show, instrument 4 with respect to main body 1 shown on the direction in the axially movable process, angle 6 can change.This has produced on outer surface 8 along the orientation-dependent reflection characteristic of the length variations of main body 1.In an example, this has comprised the group of predetermined different angles, as the function along the axial location of the outer surface 8 of main body 1, or selects as another kind of, and the angle 6 of groove 23 changes continuously as the function along the axial location of the outer surface 8 of main body 1.
Though the foregoing description relates to the formation of helical groove 23, but be appreciated that in the embodiment that another does not show, when observing in the cross section that is being parallel to longitudinal axis 2, main body 1 can have the circumferential groove of the asymmetric shape of one or more one-tenth, and these circumferential grooves press embeddings thereon and with the relatively little spacing axially-spaced in the 20-200 micrometer range.For this reason, when main body 1 during with respect to instrument 4 rotation, instrument 4 enters with main body 1 and engages, thereby forms continuous (or closure) circumferential groove.Instrument 4 is radially regained from main body 1 subsequently, and main body 1 moves axially a bit of distance relatively, and repeats this process.As previous embodiment, a key character is: when instrument 4 engages with main body and forms asymmetric groove, guarantee removal from main body 1 of material.Have been found that: thisly do not remove smoothness (with the reflectivity that the obtains therefrom) maximization that material can make the interarea of groove 23, thereby further be of value to the optical property of the outer surface 8 of main body 1.
In the above-described embodiments, the outer surface of cylinder body 1 preferably by for example 316 or the stainless steel of 316L level make.With respect to 316 grades carbon content of standard, the 316L level has one than low carbon content, and therefore has higher pliability.Therefore, the easier groove 23 that under the situation of not removing material, forms.Yet, in other embodiments, can be still with stainless other levels, or even other wrought material such as bazar metal make the outer surface 8 of main body 1.
In the above-described embodiments, though instrument is preferably made by the tungsten carbide that is coated with titanium nitride or titanium carbonitride, in other embodiments, instrument can be made by high-speed steel or any other wear-resisting shaping/other material of cutting tool level that is fit to.
In the above-described embodiments, though around longitudinal axis 2 rotation, and instrument 4 moves along it main body 1 on lathe, be appreciated that this operation also can carry out on milling machine, on this milling machine, can be implemented in the similar relative motion between instrument 4 and the main body 1.
Should be appreciated that the symbol of Shi Yonging " um " is represented micron here.
