Description
Technical field
This invention is a kind of sanding and polishing rough diamond, manufactures the processing unit (plant) of diamond cut instrument.
Background technology
What in the past, everybody was familiar with is the rough diamond cutting tool of fixed.What it mainly adopted is, in mcl rough diamond, cutting blade is installed, and waxes, or adopt fixture, the mechanical methods such as riveted joint by it on base metal or staight shank.This class cutting tool adds man-hour for the ultraprecise of aspherical lens module etc., and cutting blade is high-precision circular arc, and this circular arc normally polishing for a long time forms.
In patent documentation 1, just explicitly point out, the processing unit (plant) that cutting polishing rough diamond is manufactured diamond cutting tool should have the armed lever of maintenance and abradant surface, keeps armed lever to be used for the diamond planing tool that balance contains rough diamond composition, and abradant surface can horizontally rotate.During by former those processing unit (plant)s polishing rough diamond, first operation must be fixed on diamond on the abradant surface of rotation, measure the adamantine face that is polished with tester, confirm the grinding state of the face that is polished, polish the polygon of approximate circular arc through repeatedly repeating above-mentioned action.Next, enter second operation work, because be last rubbing down manufacturing procedure, make diamond cut instrument at balance armed lever periphery continuous moving, so just adopted the method with the diamond cut instrument of circular arc cutting blade of making in this procedure.(referring to Patent Document 1 process chart)

Summary of the invention
In recent years, for aspherical mirror machining, and profile precision to reach the market demand of diamond cut instrument of tens nanometers increasing, but the method for mentioning in above-identified patent document is difficult to produce the diamond cut instrument that profile precision is high.
Can there is anisotropy because hard is different in diamond, so while making the high instrument of profile precision, be with mill grinding method anisotropy will directly affect profile precision if adopted in patent documentation 1.When level pressure attrition process, the load amount that the strain of machinery is brought can make machine first process the crystal orientation of easy processing, and this will destroy the precision of profile, processes rough diamond and just become very difficult on the diamond cut instrument that has desirable profile precision.
For avoiding occurring grinding marks in the eccentric wear loss of abradant surface and rough diamond, the rough diamond on former processing unit (plant) keeps armed lever part in work, must make the constantly back and forth movement on abradant surface of contact point of abradant surface.This back and forth movement is to carry out along the longitudinal direction that keeps armed lever, so while processing rough diamond, its face that is polished machine direction almost remains unchanged.In the arc-shaped for blade is made, allow and keep armed lever to move back and forth, and constantly convert rough diamond and be polished the machining angle of face.In this process, the machine direction of abradant surface is sometimes just fixed on the unmanageable direction of rough diamond crystal orientation, and so, the processing progress of this direction does not just catch up with.
In addition, the shaping processing of the common diamond tool in patent documentation 1 in first operation, more much bigger than the processing capacity of rubbing down processing.Compared with car limit processing, while adopting forming and machining method processing to be polished face to show slightly coarse rough diamond, can improve process velocity by the diameter that increases diamond gravel.In the man-hour that adds that uses single mill shaping rubbing down, the abradant surface roughness that thick gravel causes has increased, but adds and will prevent that tiny gravel contact rough diamond is polished face man-hour at rubbing down.This spends the plenty of time again, also can greatly reduce adamantine machining accuracy simultaneously.
On the other hand, adopt high-energy processing and manufacturing diamond cut instrument, although can not there is the anisotropy of diamond hardness, inevitably can damage rough diamond top layer.The top layer that rough diamond is impaired, can cause being cut material increases the wellability of diamond cut instrument, when using the cutting of diamond cut instrument, together with blade easily sticks with cut material, easily there is breach in blade, finally destroys adamantine processing precision.So, although mechanical polishing above-mentioned still has problems, for removing the damaged layer on rough diamond surface, finally still need to adopt this mechanical type rubbing down manufacturing procedure.
In view of the foregoing, one of its object is to provide than carried out more simply the cutting that contour accuracy is higher sooner and can carry out the processing unit (plant) of the diamond cutting tool of attrition process in the past in the present invention.
The processing unit (plant) of diamond cutting tool of the present invention is by pedestal, with the maintenance structure that is arranged on pedestal top and has diamond and keep grinding object, and be arranged on pedestal top, abradant surface therein axle around rotates, and according to the abradant surface of its rotation, diamond profile is carried out to the processing unit (plant) of the diamond cutting tool of the abrasive configuration formation of circular-arc grinding.Lapping device of the present invention stipulates X-axis, Y-axis, the Z axis of mutual orthogonal, when the central shaft of above-mentioned abradant surface is Z axis, be arranged on the abrasive configuration on processing unit (plant) of the present invention, there is the rotary configured of the spin finishing body of abradant surface and abradant surface side, and the feature of the lifting of abradant surface side structure.Rotary configured in this above-mentioned abradant surface side, has the bearing portions of the abradant surface side that supports the rotation of spin finishing body.In addition the lifting of above-mentioned abradant surface side structure, very can be by abradant surface with Z-direction lifting to diamond.
Possess the lapping device of the diamond cutting tool of above-mentioned structure, abradant surface can be approached to diamond and size, therefore diamond can be carried out to high-precision contour machining.Contrary in this, the processing method of interlocking dish in the past, is that diamond is approached to abradant surface, the level pressure processing by diamond to abradant surface pushing.Adamantine hardness described above is different, even if same pressure pushes diamond to abradant surface, due to the different processing progresses of adamantine crystal orientation also difference to some extent.If therefore diamond is carried out to the processing that contour accuracy is higher, need skilled technical ability.
As above-mentioned as a form of processing unit (plant) of the present invention, the lifting structure part of above-mentioned abradant surface side, that the bearing portion inside bottom of the abradant surface side that supports spin finishing body is carried out to Z-direction advance and retreat, very can carry out the structure of Z-direction lifting to diamond lap face, and spin finishing body can be made as the detachable abrasive body jacking condition of bearing portion in abradant surface side.
As the concrete formation of abrasive body jacking condition, with reference to aftermentioned example as shown in Figure 4, the lifting structure part 7 of abradant surface side is to possess the inner member 7i being integrated with the inner bottom part 60c of the bearing portions 60 of abradant surface, and be arranged on the ring-type outer member 7o of inner member 7i periphery, and the peripheral surface of inner member 7i and outer member 7o in to enclose face be that screw coordinates and forms.While rotating when the time comes outer member 7o, by advancing screw can make the inner bottom part 60c being integrated with inner member 7i carry out Z-direction lifting.
Under abrasive body jacking condition, to being fixed on the diamond on high rigidity body (and keeping sideway swivel structure), can, according to advancing spin finishing body to tighten up a screw to set incision size, worsen thereby can suppress contour accuracies different by diamond hardness and that cause.Such dimensioned, different from the level pressure processing of the strain incision that is by device, can on form accuracy, form instrument point of a knife according to the running accuracy of spin finishing body.
In addition spin finishing body can freely load and unload from the bearing portion of abradant surface side, can revise the abradant surface of each spin finishing body.If while there is most different spin finishing body in the surface state of abradant surface, be easy to the surface state of controlled working precision abradant surface often to switch to optimum state, therefore when above-mentioned face correction, can not postpone operation yet, can stably carry out high-precision processing.In addition because spin finishing body is removably to form, for example, in the time that diamond is carried out to roughing, spin finishing body can be placed on to diamond wheel, when fine finishining, can select the metal grinding face of the free abrasive grains of diamond.By select suitable abradant surface in each process, can promptly carry out the processing that contour accuracy is higher like this.Because the handling of spin finishing body can be fixed on diamond on body and carry out, while therefore switching spin finishing body according to engineering, also can measure exactly the size of clearance angle and circular shape semicircle.
Neoteric processing unit (plant) above-mentioned is that a kind of axle is subject to portion's lowering or hoisting gear.The lift of abradant surface, makes the whole axle of the abradant surface portion that is subject to move forward and backward toward z direction of principal axis, and the abradant surface of rough diamond moves up and down toward z axle aspect, and the axle portion of being subject to of abradant surface is fixed on abradant surface lift.
It is elevator gear 7 ' that axle is subject to the main composition part of the lift of portion, as shown in Figure 8, elevator gear 7 ' comprises the base station 70 ' being fixed on base α, can allow sky plate 71 ' that abradant surface freely moves up and down on base station on z direction of principal axis and be subject to portion 60 ' at the upper axle that abradant surface is installed of sky plate 71 '.By keeping the holding structure that grinds object to be fixed on the α of pedestal portion heaven plate 71 ' part in addition, just can start to allow abradant surface approach fixed cun of cutting of rough diamond.
Axle is subject to portion's lowering or hoisting gear the same with abrasive body lowering or hoisting gear, can determine a cun cutting rough diamond.Be subject in portion's lowering or hoisting gear at axle, the axle of the abradant surface portion that is subject to can be from the free installation or removal of the lowering or hoisting gear of abradant surface, in abrasive body lowering or hoisting gear, spin finishing body also can be subject to the free installation or removal of portion from the axle of abradant surface, can easily change abradant surface according to purposes.
Another component part of neoteric processing unit (plant) is holding device and lapping device.Holding device is by extending along Y-direction, can be endways monolateral balance is ground the balance armed lever portion material of object and the whirligig that balance armed lever portion material is moved back and forth along the circular arc of Y-axis periphery, lapping device comprise the whirligig that makes abradant surface along X-axis parallel direction linearly type or circular arc type move back and forth carry out return device.

The whirligig of abradant surface moves back and forth along the direction that is parallel to X-axis, while namely allowing abradant surface move back and forth along the direction of close X-axis, take the contact point of rough diamond and abradant surface as summit, track take the pivot on the abradant surface of spin finishing body in the process of moving back and forth forms a triangle as base, the angle θ of the contact point of rough diamond and abradant surface is good in should being controlled between 5 °～180 °.The angle excursion of rough diamond machine direction is also 5 °～180 °, and the high order crystal plane that circular cone is processed to form also can change machine direction between 5 °～180 °, and this change procedure can allow machine direction higher with the compatible degree of condition that meets processing.If this angle is 180 °, the track of the rotary middle point in the process that moves back and forth on the abradant surface of spin finishing body is exactly the contact point of rough diamond and abradant surface.
Carried above, holding device is also a component part of this neoteric processing unit (plant), and holding device comprises the base portion being arranged on base, keeps armed lever, goniometer, and turntable, keeps elevator gear.Keep armed lever, extend along Y direction, monolateral balance is ground object endways.For guaranteeing to keep the front end of armed lever supporting along the circular arc rotation goniometer of x axle periphery the bottom that keeps armed lever.Turntable is supporting goniometer, and it can be rotated along Y-axis.And keep elevator gear to make to keep armed lever, and goniometer, turntable entirety moves toward Z-direction.
Because there is maintenance elevator gear, so add man-hour, rough diamond can be fixed on to the correct position on Z axis.While machining, rough diamond, easily from Z axis top slippage, keeps armed lever can guarantee again to take out safely rough diamond.
Keep elevator gear as one of component part of this neoteric processing unit (plant), comprise clava, hammer portion material with contact pressure adjusting device.Clava is arranged on the opposite side that has goniometer on turntable.Hammer portion material is arranged on clava, can be free to slide.Contact presses adjusting device can change and be positioned at clava compared with the position of the hammer portion material of length direction, the weight of whole portion material and the weight of hammer portion material when thereby balance keeps lift running, by adjusting the balance of weight, just can adjust the pressure while grinding object contact abradant surface.
Because have goniometer and turntable, so when plane lapping rough diamond, can precisely adjust the angle of rough diamond abradant surface.Specifically, measure and be placed in the shape that keeps rough diamond 3 dimensions on armed lever, decide the angle of the face of being polished according to this shape, carry out polishing according to fixed dimensional accuracy and form accuracy.Especially when processing dimension and shape are all when irregular natural rough diamond, can effectively in rough diamond, form a facet.
In this structure, because the installation site of hammer portion material is transformable, so keep the angle of grinding object and abradant surface constant, just can adjust easily the contact of rough diamond and abradant surface.
When roughing rough diamond, also can not use this neoteric processing unit (plant), high-energy processing machine can complete equally.When carrying out continuously back rotation rough diamond and carrying out polishing with this neoteric processing unit (plant).
Even if be not very consummate skilled worker, use neoteric diamond cut tool processes device, also can produce the diamond cut instrument that contour accuracy is high.

Although the processing unit (plant) of this example is also to be approached and adamantinely formed by abradant surface 5s, in the attrition process of diamond 90 at the end, start and keep side lifting structure 15 ', withdraw diamond from abradant surface 5s better.In the time that diamond 90 is isolated, the possibility of hurt diamond 90 is lower like this.
[example 3]
Example 3 is to the abrasive structure γ of the example 1,2 that grinds object 9 is replaced with to the formation explanation of abrasive structure γ ' as shown in Figure 8.Because abrasive structure γ ' formation and example 1,2 is in addition same, the formation of abrasive structure γ ' is mainly described afterwards, about diagram and the explanation of holding structure are all omitted with reference to Fig. 8.In addition this example 3 also can be to carrying out abradant surface correcting principle 900 explanation in the lump of align hone face 5s.
In example, the abrasive structure γ of 1 explanation as shown in Figure 4, is the formation that can freely load and unload for the bearing portions 60 spin finishing bodies 5 of abradant surface side, therefore new as long as replacing spin finishing body 5 just can make abradant surface 5s become.But in this formation, while grinding diamond, in the thrust ball 5c of the interior support spin finishing of bearing portions 60 body 5 and the counter-force of the concentrated sizing incision of its forced section (depression) meeting of abradant surface side.Thrust ball 5c and the forced section distortion thereof such as while grinding so for a long time, in the time of spin finishing body 5, abradant surface 5s produces skew at the face that rocking, and has the low possibility of lifting precision of spin finishing body 5.Therefore in example 3, adopted the abrasive structure γ ' that can eliminate this problem points.
As shown in Figure 8, the spin finishing body 5 ' of abrasive structure γ ', possessing has the integrated disc portions 5b ' of abradant surface 5s ' and for being fastened on the pad 5c ' of rotating part 60b ' of this integrated disc portions of aftermentioned 5b ' (the bearing portions 60a ' of abradant surface side).In addition, this pad 5c ' and integrated disc portions 5b ' prepare respectively, also can be connected with integrated disc portions 5b ' more afterwards.
The rotational structure 6 ' that grinds on the one hand side possesses the bearing portions 60 ' of the abradant surface side that can make the 5 ' rotation of spin finishing body, is accommodated with the air bearing (hydrostatic bearing 60a ') of rotating part 60b ' and air supply section 60c ' in the inside of this bearing 60 '.The rotating part 60b ' of air bearing 60a ' is fixed on rotating shaft direction and rotation footpath direction for air supply section 60c ' by air layer.Therefore be fixed on the spin finishing body 5 ' on the rotating part 60b ' of this air bearing 60a ', can be shifted easily when rotated.In addition, the inside of bearing 60 ' is fixed wtih power source 61 ', and the rotating part 60b ' of air bearing 60a ' is directly connected with this power source 61 ', is can be according to the formation of power source 61 ' direct spin finishing body 5 '.In the abrasive structure γ ' of this example that possesses such formation, air bearing 60a ' passes through air layer, dispersible the counter-force that receives sizing incision, no longer include the concentrated place of counter-force, the abrasive structure γ ' of this example as shown in Figure 8, on thrust ball 5c, spin finishing body 5 is the formations that a bit hang as shown in Figure 4, needn't worry the distortion of inscape and makes running accuracy deteriorated.Even if so for a long time diamond is ground, on rotary body 5 ', be difficult to the distortion of the running accuracy hurt that rotates abrasive body 5 '.In addition as Fig. 8 medium power source 61 ' is ensconced in bearing portions 60 ', as Fig. 3, the dynamic rotation abrasive body 5 that is arranged on external power supply by pulley and driving-belt transmission shown in 4 is for well.While bringing the driving force of reception and registration external power supply to obtain grinding the driving force of rotary body 5 ' by pulley and transmission, easily loading and unloading as driving-belt, outside power source is made as to the structure of sliding a little better.
The rotary body combination that has adopted the rotational structure 6 ' of spin finishing body 5 ' and abradant surface side to be integrated as above-mentioned in this example, this rotary body combination does not comprise the structure that makes abradant surface 5s ' lifting.So adopted the lifting structure part 7 ' of the abradant surface side that makes above-mentioned rotary body combination lifting in this example.
