由粗研磨作業和精研磨作業構成之球面透鏡的研磨加工方法有下述要解決的課題。首先，因粗研磨維持加工精度較困難，所以在精研磨作業會因透鏡素材形狀不均造成鉢形砂輪的磨損激烈，有時就難以維持精研磨的加工精度。此外，粗研磨和精研磨是需要各別不同的加工技術，因此就需要各別加工技術熟練的技術者。The polishing method of a spherical lens composed of a rough polishing operation and a fine polishing operation has the following problems to be solved. First, it is difficult to maintain the machining accuracy by the rough grinding. Therefore, in the fine grinding operation, the wear of the crown-shaped grinding wheel is severe due to the uneven shape of the lens material, and it is sometimes difficult to maintain the precision of the finishing polishing. In addition, rough grinding and fine grinding require different processing techniques, and thus skilled artisans are required.

為了解決上述課題，本發明是一種將具備有金剛石磨粒之球狀砂輪面的鉢形砂輪以指定的加工壓力抵壓研磨對象透鏡素材的被研磨面，在該狀態下，以指定的旋轉數旋轉上述鉢形砂輪的同時邊擺動邊將上述被研磨面研磨成球面之使用鉢形砂輪之透鏡球面的研磨加工方法，其特徵為，具有：上述加工壓力為第1加工壓力，上述旋轉數為第1旋轉數進行研磨的初期研磨步驟；上述加工壓力為第2加工壓力，上述旋轉數為第2旋轉數進行研磨的中期研磨步驟；及上述加工壓力為第3加工壓力，上述旋轉數為第3旋轉數進行研磨的後期研磨步驟，上述第2加工壓力是能夠使上述球狀砂輪面侵入上述透鏡素材的壓力，接著從上述透鏡素材的硬度，及上述透鏡素材的上述被研磨面和上述鉢形砂輪的上述球狀砂輪面之接觸面積，算出上述鉢形砂輪的侵入量，根據該侵入量算出上述第2加工壓力，上述第2旋轉數，設定成可將上述加工壓力設定成上述第2加工壓力的狀況下使上述鉢形砂輪的上述金剛石磨粒侵入上述透鏡素材的旋轉數，上述第1加工壓力設定成比上述第2加工壓力還低的值，上述第1旋轉數設定成比上述第2旋轉數還低的值，上述第3加工壓力設定成比上述第1加工壓力還低的值，上述第3旋轉數設定成比上述第2旋轉數還低但比上述第1旋轉數還高的值。In order to solve the above problems, the present invention is a method in which a beryllion grinding wheel having a spherical grinding wheel surface having diamond abrasive grains is pressed against a surface to be polished of a lens material to be polished at a predetermined processing pressure, and in this state, rotated by a predetermined number of rotations.

以下，參照圖面對應用本發明的透鏡球面之研磨加工方法的實施形態進行說明。Hereinafter, an embodiment of a polishing method for a lens spherical surface to which the present invention is applied will be described with reference to the drawings.
(球芯式透鏡研磨加工裝置)(Spherical lens grinding processing device)

The core lens polishing apparatus 1 includes an upper unit 2 and a lower unit 3. The upper unit 2 is provided with a lens holder 4 in a downward state, and the lens holder 4 is attached to the lower end of the lens pressurizing shaft 5, and can be pressed downward in the direction toward the unit central axis 2a by the pressurizing cylinder 6.

Centering on, the crown-shaped grinding wheel 8 can be swung at a set swing angle θ, a set machining radius R, and a set swing direction.
於此，加壓缸筒6的加壓力，可由第1調節器12、第2調節器13及第3調節器14轉換成三階段。由該等第1調節器12、第2調節器13及第3調節器14設定壓力的動作流體，分別是透過可轉換開關的第1～第3轉換閥15、16、17供應至加壓缸筒6。該構成的加壓機構(透鏡加壓軸5、加壓缸筒6、第1～第3調節器12～14、第1～第3轉換閥15～17)的加壓力轉換控制是轉換第1～第3轉換閥15～17就能夠執行。Here, the pressing force of the pressurizing cylinder 6 can be converted into three stages by the first regulator 12, the second regulator 13, and the third regulator 14.

(研磨加工動作的一例)(An example of the polishing processing operation)
第2圖是表示球芯式研磨加工裝置1之球面透鏡的研磨加工動作的概略流程圖。參照第1圖、第2圖進行說明時，首先，將透鏡素材7安裝在透鏡保持具4的透鏡保持面4a，形成為透鏡素材7的被研磨面7a抵壓在鉢形砂輪8之球狀砂輪面8a的狀態(透鏡素材供應步驟ST1)。Fig. 2 is a schematic flow chart showing the polishing operation of the spherical lens of the core-type polishing apparatus 1. Referring to FIGS. 1 and 2, first, the lens material 7 is attached to the lens holding surface 4a of the lens holder 4, and the spherical surface of the lens material 7 is pressed against the spherical grinding wheel 8 of the dome-shaped grinding wheel 8. The state of the face 8a (lens material supply step ST1).
在該狀態下，開始旋轉、擺動鉢形砂輪8，開始進行透鏡素材7的被研磨面7a的研磨加工。從研磨加工的開始時間點至指定時間經過為止的初期研磨步驟ST2，是以第1調節器12所設定的加工壓力於透鏡素材7抵壓在鉢形砂輪8的狀態下進行研磨加工。因為透鏡素材7接觸在鉢形砂輪8的面積較小，所以加工壓力以停留在能夠不讓透鏡素材7從透鏡保持具4及鉢形砂輪8之間脫落的最小限度為佳，形成為比下一個步驟即中期研磨步驟的加工壓力還小。此外，初期研磨步驟的鉢形砂輪8的旋轉數是以較低的旋轉數為佳，但從兼顧加工時間的觀點來看，以400～600rpm為佳。該旋轉數，同樣是比下一個步驟即中期研磨步驟的旋轉數還小。In this state, the grinding wheel 8 is started to be rotated and oscillated, and the polishing process of the surface 7a of the lens material 7 is started. The initial polishing step ST2 from the start time of the polishing process to the passage of the predetermined time is performed by the lens material 7 being pressed against the crown grinding wheel 8 at the processing pressure set by the first regulator 12. Since the lens material 7 is in contact with the area of the dome-shaped grinding wheel 8, the processing pressure is preferably kept to a minimum extent that the lens material 7 can be prevented from falling between the lens holder 4 and the crown-shaped grinding wheel 8, and is formed to be smaller than the next step. That is, the processing pressure of the medium-stage grinding step is still small. Further, the number of rotations of the crown-shaped grinding wheel 8 in the initial grinding step is preferably a low number of rotations, but it is preferably 400 to 600 rpm from the viewpoint of achieving the processing time. The number of rotations is also smaller than the number of rotations of the next step, that is, the intermediate grinding step.
於初期研磨步驟ST2中，當透鏡素材7的被研磨面7a的研磨持續，使該被研磨面7a形成為大致接觸到鉢形砂輪8的球狀砂輪面8a的狀態時就將加工壓力轉換成第2調節器13所設定的加工壓力。如此一來，研磨加工就進入中期研磨步驟ST3。In the initial polishing step ST2, when the polishing surface 7a of the lens material 7 continues to be polished, and the surface to be polished 7a is formed to substantially contact the spherical grinding wheel surface 8a of the crown-shaped grinding wheel 8, the processing pressure is converted into the first 2 The processing pressure set by the regulator 13. As a result, the grinding process enters the intermediate grinding step ST3.
中期研磨步驟ST3的加工壓力是能夠使鉢形砂輪8的磨粒(金剛石刀刃)侵入透鏡素材7的壓力。加工壓力是以設定成能夠侵入透鏡素材7之壓力的最小值或者是該附近的值為佳。球面透鏡研磨通常所要求的表面粗糙度為4μm程度。因此，施加在透鏡素材7的加工壓力是從該透鏡素材7的硬度，及透鏡素材7的被研磨面7a和鉢形砂輪8的球狀砂輪面8a之接觸面積，算出鉢形砂輪8的侵入量，根據該侵入量，就能夠算出中期研磨步驟的加工壓力。The processing pressure in the intermediate polishing step ST3 is a pressure at which the abrasive grains (diamond blades) of the dome-shaped grinding wheel 8 can intrude into the lens material 7. The processing pressure is preferably a value which is set to a minimum value of the pressure at which the lens material 7 can be invaded or a value in the vicinity. Spherical lens grinding generally requires a surface roughness of about 4 μm. Therefore, the processing pressure applied to the lens material 7 is calculated from the hardness of the lens material 7 and the contact area between the surface 7a of the lens material 7 and the spherical grinding wheel surface 8a of the crown-shaped grinding wheel 8, and the amount of penetration of the crown-shaped grinding wheel 8 is calculated. Based on the amount of intrusion, the processing pressure in the intermediate polishing step can be calculated.
此外，中期研磨步驟的鉢形砂輪8的旋轉數是設定成能夠使鉢形砂輪8的磨粒(金剛石刀刃)侵入透鏡素材7的旋轉數。所謂能夠侵入透鏡素材7的旋轉數是指設定成如上述的加工壓力使鉢形砂輪的旋轉數改變時，可使加工時間幾乎沒有改變之最大旋轉數以下的旋轉數。即，旋轉數若是比該最大旋轉數還高時，則導致的狀況是加工時間無法縮短，鉢形砂輪的球狀砂輪面和透鏡素材的被研磨面之間產生滑動，磨粒不能侵入透鏡素材表面的狀況。旋轉數是以設定成能夠侵入透鏡素材7之旋轉數的最大值或者是該附近的值為佳。Further, the number of rotations of the dome-shaped grinding wheel 8 in the medium-stage grinding step is set to a number of rotations at which the abrasive grains (diamond blades) of the crown-shaped grinding wheel 8 can intrude into the lens material 7. The number of rotations that can enter the lens material 7 is a number of rotations that are set to be equal to or less than the maximum number of rotations at which the machining time hardly changes when the number of rotations of the crown-shaped grinding wheel is changed as described above. In other words, if the number of rotations is higher than the maximum number of rotations, the machining time cannot be shortened, and the spherical grinding wheel surface of the crown-shaped grinding wheel and the surface to be polished of the lens material are slid, and the abrasive grains cannot intrude into the surface of the lens material. The situation. The number of rotations is preferably a maximum value of the number of rotations that can be intruded into the lens material 7, or a value in the vicinity.
中期研磨步驟的研磨持續，使透鏡素材7的中心厚度成為目標厚度還稍微厚之值的階段，就將加工壓力轉換成第3調節器14所設定的加工壓力。藉此使研磨加工進入後期研磨步驟ST4。The polishing in the medium-stage polishing step is continued, and the machining pressure is converted into the machining pressure set by the third regulator 14 at a stage where the center thickness of the lens material 7 is slightly thicker than the target thickness. Thereby, the grinding process is advanced to the post-grinding step ST4.
後期研磨步驟是將研磨加工的進行速度減慢(降低鉢形砂輪8的旋轉數)，以透鏡素材7的中心厚度不會產生不均的狀態進行研磨。使被研磨面7a的表面粗糙度研磨成目標值的表面粗糙度。後期研磨步驟，其加工壓力是設定成比初期研磨步驟的加工壓力還要更低的壓力，其鉢形砂輪8的旋轉數是設定成比中期研磨步驟的旋轉數還低，但比初期研磨步驟的旋轉數還高的值。In the post-grinding step, the progress of the lapping process is slowed down (the number of rotations of the beak-shaped grinding wheel 8 is reduced), and polishing is performed in a state where the center thickness of the lens material 7 is not uneven. The surface roughness of the surface to be polished 7a is ground to a surface roughness of a target value. In the post-grinding step, the processing pressure is set to a pressure lower than the processing pressure of the initial grinding step, and the number of rotations of the crucible grinding wheel 8 is set to be lower than the number of rotations in the intermediate grinding step, but is lower than the initial grinding step. The number of rotations is still high.
於此，使用鉢形砂輪的球面研磨是一種具有複數切削刃之金鋼石刀刃的切削加工。因此，研磨加工條件的加工壓力及鉢形砂輪旋轉數是可根據透鏡素材的硬度進行設定。即，加工壓力只要設定成與透鏡素材的硬度成比例，旋轉速度只要設定成與透鏡素材的硬度成反比例即可。透鏡素材的硬度數據是從素材型錄等就能夠簡單獲得，因此根據該透鏡素材的硬度就可算出最佳的加壓力、旋轉數。Here, the spherical grinding using the 钵-shaped grinding wheel is a cutting process of a diamond blade having a plurality of cutting edges. Therefore, the processing pressure of the polishing processing conditions and the number of rotations of the crown-shaped grinding wheel can be set according to the hardness of the lens material. That is, the machining pressure is set to be proportional to the hardness of the lens material, and the rotation speed may be set to be inversely proportional to the hardness of the lens material. Since the hardness data of the lens material can be easily obtained from the material type record or the like, the optimum pressing force and the number of rotations can be calculated from the hardness of the lens material.
其次，對透鏡素材7的被研磨面7a進行研磨的鉢形砂輪8的球狀砂輪面8a的部份若經常為同一部份時，則砂輪面會產生偏磨損導致研磨形狀改變。因此，以定期性改變透鏡素材7之被研磨面7a所抵接的球狀砂輪面8a的位置(球狀砂輪面8a上的被研磨面7a的滑動區域)，防止球狀砂輪面8a的偏磨損，使球狀砂輪面8a全體均勻磨損，保持一定的研磨精度為佳。並以至少於中期研磨步驟改變球狀砂輪面8a上的被研磨面7a的滑動區域為佳。Next, if the portion of the spherical grinding wheel surface 8a of the crown-shaped grinding wheel 8 which is polished on the surface to be polished 7a of the lens material 7 is often the same portion, the grinding wheel surface is subjected to partial wear to cause a change in the grinding shape. Therefore, the position of the spherical grinding wheel surface 8a (the sliding area of the surface to be polished 7a on the spherical grinding wheel surface 8a) where the surface to be polished 7a of the lens material 7 abuts is periodically changed, and the deviation of the spherical grinding wheel surface 8a is prevented. Wear and wear, so that the spherical grinding wheel surface 8a is uniformly worn, and it is preferable to maintain a certain grinding precision. It is preferable to change the sliding area of the surface to be polished 7a on the spherical grinding wheel surface 8a at least in the intermediate grinding step.
如以上說明，本實施形態中，對於球面研磨，使加工初期的加工壓力為低壓，旋轉速為低速，藉此就能夠防止加工對象透鏡素材的缺損、龜裂。於加工中期，相較於加工初期是將加工壓力轉換成高壓，將旋轉數轉換成高速，藉此就能夠縮短加工時間。於加工末期，將加工壓力形成比加工初期還低壓，將旋轉數形成比加工初期還快，但比加工中期還慢的中等速度，藉此就能夠確保透鏡素材中心厚度的精度。如上述，配合研磨的進行以多階段改變研磨條件，只要使用鉢形砂輪就能夠使透鏡素材形成有高精度的精研磨面。As described above, in the present embodiment, in the case of the spherical polishing, the processing pressure at the initial stage of the processing is made low, and the rotation speed is low, whereby the defect or crack of the lens material to be processed can be prevented. In the middle of processing, the processing pressure is converted to a high pressure and the number of revolutions is converted to a high speed as compared with the initial stage of processing, whereby the processing time can be shortened. At the end of the processing, the processing pressure is formed at a lower pressure than the initial stage of the processing, and the number of revolutions is formed faster than the initial stage of processing, but at a medium speed which is slower than the middle of the processing, whereby the accuracy of the center thickness of the lens material can be ensured. As described above, the polishing conditions are changed in multiple stages in accordance with the progress of the polishing, and the lens material can be formed with a highly precise fine polishing surface by using a dome-shaped grinding wheel.
(實驗例)(Experimental example)
本發明人等是使用本發明的研磨方法進行了下述加工。The inventors of the present invention performed the following processing using the polishing method of the present invention.
本實施例的加工數據如下述：The processing data of this embodiment is as follows:
透鏡素材的材質 TAFD25Material of lens material TAFD25
透鏡素材的磨損度 90Lens material wear 90
透鏡素材的努氏硬度 630Knoop hardness of lens material 630
加工球面半徑R 180mmProcessing spherical radius R 180mm
透鏡外徑 37.5mmLens outer diameter 37.5mm
鉢形砂輪 金剛石粒 SP60B #800钵 shaped grinding wheel diamond grain SP60B #800
首先，進行能夠決定加工壓力的測試。測試條件如下述，測試結果如第3圖的表及圖表所示。First, a test capable of determining the processing pressure is performed. The test conditions are as follows, and the test results are shown in the table and graph of Fig. 3.
球芯式透鏡研磨加工裝置 NC研磨機 PM50型(製造商：KOJIMA EAGINEERING有限公司)Core lens grinding equipment NC grinding machine PM50 (manufacturer: KOJIMA EAGINEERING Co., Ltd.)
鉢形砂輪的旋轉數 1000rpmNumber of rotations of the grinding wheel 1000rpm
鉢形砂輪的透鏡接觸面積 4.52cm2 The lens contact area of the 砂-shaped grinding wheel is 4.52cm 2
加工量 0.1mmProcessing capacity 0.1mm
從測試結果得知，加工壓力為10kg/cm2 以上時，透鏡素材的磨損量幾乎沒有改變，因此該壓力就是研磨加工效率之最大的點。It is known from the test results that the wear amount of the lens material hardly changes when the processing pressure is 10 kg/cm 2 or more, and therefore the pressure is the point at which the grinding processing efficiency is the greatest.
其次，使用同一球芯式透鏡研磨加工裝置，進行能夠決定鉢形砂輪旋轉數的測試，在加工壓力1(15 kg/cm2 )及加工壓力2(10 kg/cm2 )的狀況下，調查旋轉數改變時的加工時間。測試條件除了加工壓力以外其他是和上述的狀況相同。測試結果如第4圖的圖表所示。Next, using the same spherical lens polishing apparatus, a test capable of determining the number of rotations of the crown-shaped grinding wheel was performed, and the rotation was investigated under the conditions of the processing pressure 1 (15 kg/cm 2 ) and the processing pressure 2 (10 kg/cm 2 ). The processing time when the number is changed. The test conditions are the same as those described above except for the processing pressure. The test results are shown in the graph in Figure 4.
從該測試結果得知，旋轉數接近1500rpm附近時磨損量幾乎沒有改變，因此該點就是加工效率最大的點。即，當加工壓力為一定，只提高旋轉數時加工時間幾乎沒有改變的旋轉數就是「能夠侵入的旋轉數」的最大值，若旋轉數提高成比該值還大時，就會形成為透鏡素材和鉢形砂輪產生滑動，鉢形砂輪的磨粒不會侵入透鏡素材表面的狀況。該「能夠侵入的旋轉數」的最大值就是加工效率最大的點。該最大值，會因透鏡素材的硬度、鉢形砂輪磨粒的粒度、切削液的性能等不同而有所變動，因此只要進行測試加以設定即可。From the test results, it is known that the amount of wear hardly changes when the number of rotations is close to 1500 rpm, so this point is the point at which the processing efficiency is the greatest. In other words, when the machining pressure is constant, the number of rotations in which the machining time hardly changes when only the number of rotations is increased is the maximum value of the "number of rotations that can be invaded". When the number of rotations is increased to be larger than the value, the lens is formed as a lens. The material and the squeegee wheel are slid, and the abrasive grains of the 砂-shaped grinding wheel do not intrude into the surface of the lens material. The maximum value of the "number of rotations that can be invaded" is the point at which the processing efficiency is the largest. This maximum value varies depending on the hardness of the lens material, the particle size of the abrasive grain of the crown-shaped grinding wheel, and the performance of the cutting fluid. Therefore, it is only necessary to perform a test and set it.
根據該等測試結果時，得知中期研磨步驟ST3的加工條件是以加工壓力為10 kg/cm2 ，鉢形砂輪的旋轉數為1500rpm為最佳。以該條件為基準，分別設定初期研磨步驟ST2及後期研磨步驟ST4的加工條件。From the results of the tests, it was found that the processing conditions of the intermediate grinding step ST3 were carried out at a processing pressure of 10 kg/cm 2 and the number of rotations of the crown-shaped grinding wheel was 1,500 rpm. The processing conditions of the initial polishing step ST2 and the post-polishing step ST4 are set based on the conditions.
本發明人等的實驗是於初期研磨步驟中，將加工壓力為2 kg/cm2 ，鉢形砂輪的旋轉數為500rpm，進行了10秒鐘的研磨加工。其次，進入中期研磨步驟，將加工壓力為10 kg/cm2 ，鉢形砂輪的旋轉數為1500rpm，進行了研磨加工直到透鏡素材成為多出目標厚度之0.1mm的厚度為止，接著，進入後期研磨步驟，將加工壓力為1.5 kg/cm2 ，鉢形砂輪的旋轉數為1000rpm，進行了研磨加工直到透鏡素材成為目標厚度為止。The inventors of the present invention conducted an experiment in which the processing pressure was 2 kg/cm 2 in the initial polishing step, the number of revolutions of the crown-shaped grinding wheel was 500 rpm, and the polishing was performed for 10 seconds. Next, in the medium-stage grinding step, the processing pressure is 10 kg/cm 2 , the number of rotations of the 砂-shaped grinding wheel is 1500 rpm, and the grinding process is performed until the lens material becomes a thickness of 0.1 mm of the target thickness, and then proceeds to the post-grinding step. The processing pressure was 1.5 kg/cm 2 , the number of rotations of the 砂-shaped grinding wheel was 1000 rpm, and the grinding process was performed until the lens material became the target thickness.
其結果，可確認厚度精度是在±0.005μm以內。此外，對研磨加工面的曲率進行了測定，結果是若進行150次加工時，ΔH會變成-0.001μm。將擺動位置移位10%又進行150次加工時，ΔH會回到基準值，因此就將擺動位置恢復成原來位置。經由持續進行該等測試，終於能夠確認研磨加工面的曲率為ΔH是在0～0.001μm的範圍內。As a result, it was confirmed that the thickness accuracy was within ±0.005 μm. Further, the curvature of the polished surface was measured, and as a result, ΔH was changed to -0.001 μm when the processing was performed 150 times. When the swing position is shifted by 10% and the machining is performed 150 times, ΔH returns to the reference value, so the swing position is restored to the original position. By continuing these tests, it was finally confirmed that the curvature of the polished surface was ΔH in the range of 0 to 0.001 μm.
