Description

組合式砂輪Combined grinding wheel

本發明係關於一種組合式砂輪，尤其一種具有凹型研磨槽的組合式砂輪。 The invention relates to a combined grinding wheel, especially a combined grinding wheel with concave grinding grooves.

光學鏡片是一項精密的工業技術，其成品可以做為視覺輔助的眼鏡、顯微設備、天文觀測設備等，也利用於攝影鏡頭、投影機、光碟機等各式光學設備，特別是近年來行動電話搭配攝錄影功能，因鏡頭所需，使光學鏡片的用量與日俱增。 Optical lens is a sophisticated industrial technology, and its finished products can be used as visually assisted glasses, microscopic equipment, astronomical observation equipment, etc., and also used in various optical equipment such as photographic lenses, projectors, optical disk drives, especially in recent years The mobile phone is equipped with a video recording function. Due to the need of the lens, the amount of optical lenses is increasing day by day.

一個精密的鏡面是經過許多道製程而完成，切割、研磨、拋光、定芯等製造製程，之後，根據用途有的還會進行鍍膜、塗墨等製程。在定芯製程中，係以夾具夾持鏡片旋轉，使鏡片的邊緣與砂輪的研磨面接觸進行研磨，進而控制鏡片的外徑、深度、以及倒角。 A precise mirror surface is completed through many manufacturing processes, such as cutting, grinding, polishing, core setting and other manufacturing processes. Afterwards, some processes such as coating and ink coating will also be carried out according to the purpose. In the core setting process, the lens is clamped to rotate the lens, so that the edge of the lens is in contact with the grinding surface of the grinding wheel for grinding, and then the outer diameter, depth, and chamfer of the lens are controlled.

一般而言，砂輪為獨立的砥石，側邊(外沿)形成研磨凹槽，定芯製程時就是用此研磨凹槽研磨鏡片的邊緣。研磨凹槽會有兩個對向的傾斜面，是用來倒角的，研磨凹槽的底部是一個研磨平面，用於外徑的處理。 Generally speaking, the grinding wheel is an independent grindstone, and the side (outer edge) forms a grinding groove. This grinding groove is used to grind the edge of the lens during the core setting process. The grinding groove will have two opposite inclined surfaces, which are used for chamfering. The bottom of the grinding groove is a grinding plane for the treatment of the outer diameter.

研磨凹槽的研磨表面設有研磨粒子(顆粒)，不同研磨粒徑大小的研磨粒子所進行的研磨效果會不同。然而，習知技術的砂輪一旦磨耗使研磨粒子脫落的話，為維持鏡片的良率，就得立刻更換整個砂輪，但有時僅是一個小區域的過度磨耗就要整個砂輪換新，難免形成浪費而增加生產成本。 The grinding surface of the grinding groove is provided with grinding particles (particles), and the grinding effect of the grinding particles with different grinding particle sizes will be different. However, once the grinding wheels of the conventional technology are worn and the abrasive particles fall off, in order to maintain the yield of the lens, the entire grinding wheel must be replaced immediately, but sometimes only Excessive wear in a small area requires the entire grinding wheel to be renewed, which inevitably creates waste and increases production costs.

因此，本發明的主要目的在於提供一種可替換輪片的組合式砂輪。 Therefore, the main object of the present invention is to provide a combined grinding wheel with replaceable wheels.

本發明之其中一目的在提供一種利用於鏡片定芯製程之組合式砂輪，利用多個砂輪部件或砥石相互組成以周緣(外沿)形成研磨凹槽，不僅可用於鏡片的外徑、深度、以及倒角製作。理想時，當其中任一砂輪部件或砥石的研磨粒子有過度磨損時，只要更換不良的砂輪部件或砥石即可，不需整個砂輪更換而形成浪費。 One of the objects of the present invention is to provide a combined grinding wheel used in the lens centering process. A plurality of grinding wheel components or grindstones are used to form a grinding groove on the periphery (outer edge), which can be used not only for the outer diameter, depth, and depth of the lens. And chamfer production. Ideally, when the abrasive particles of any of the grinding wheel components or whetstones are excessively worn, it is sufficient to replace the bad grinding wheel components or whetstones, without replacing the entire grinding wheel and forming waste.

本發明的一觀點，在於提供一種組合式砂輪，組合式砂輪係分別由至少兩或三個砂輪部件組合而成，而各個砂輪部件得具有一研磨表面，各個砂輪部件經組合後，組合式砂輪得具有一研磨凹槽，而該凹槽得包括各砂輪部件的研磨表面之至少一部份。 One aspect of the present invention is to provide a combined grinding wheel. The combined grinding wheel is composed of at least two or three grinding wheel parts, and each grinding wheel part must have a grinding surface. After each grinding wheel part is combined, the combined grinding wheel There must be a grinding groove, and the groove must include at least a part of the grinding surface of each grinding wheel component.

再者，組合式砂輪亦得由至少兩個或三個輪型砥石組合而成，各個輪型砥石的外沿具有一研磨表面，經組合各輪型砥石後，研磨表面得大致呈一凹槽狀，而左右兩側砥石的研磨表面的至少一部份係相對於中間的輪型砥石的表面為傾斜且為相互面對的。 Furthermore, the combined grinding wheel must also be composed of at least two or three wheel-shaped grindstones. The outer edge of each wheel-shaped grindstone has a grinding surface. After the combination of the wheel-shaped grindstones, the grinding surface is roughly a groove At the same time, at least a part of the grinding surface of the left and right grindstones is inclined with respect to the surface of the wheel-shaped grindstone in the middle and faces each other.

請同時參閱圖1A以及圖1B，圖1A係本發明組合式砂輪的一實施例之分離示意圖。圖1B係本發明組合式砂輪於同一實施例之組合示意圖。通常，組合式砂輪10係由至少二個以上的砂輪部件12組合而成，而本實施例中則包括有三個砂輪部件12。於本例中，三個砂輪部件12之外緣(外沿)為具有研磨粒子之研磨表面，三個砂輪部件12彼此以側面緊鄰貼附以相互組合，結合後成為圖1B之組合式砂輪10。由圖可見，組合式砂輪10具有一研磨凹槽，而其同時包括各個砂輪部件12的至少一部份。 Please refer to FIG. 1A and FIG. 1B at the same time. FIG. 1A is a separation schematic diagram of an embodiment of the combined grinding wheel of the present invention. FIG. 1B is a schematic diagram of the combined grinding wheel of the present invention in the same embodiment. Generally, the combined grinding wheel 10 is composed of at least two grinding wheel components 12, and in this embodiment, three grinding wheel components 12 are included. In this example, the outer edges (outer edges) of the three grinding wheel members 12 are abrasive surfaces with abrasive particles, and the three grinding wheel members 12 are attached to each other next to each other to be combined with each other. After being combined, they become the combined grinding wheel 10 of FIG. 1B . As can be seen from the figure, the combined grinding wheel 10 has a grinding groove, and it also includes at least a part of each grinding wheel component 12.

而當本實施例的組合式砂輪10應用在製造鏡片之定芯製程中時，砂輪部件12接合後的研磨面會呈現一凹狀，亦即為研磨凹槽14。研磨凹槽14可用於進行鏡片的外徑、深度、以及倒角製作。為了使接合後的研磨凹槽14精準，所以如圖1A中可見砂輪部件12上有定位子16，與另一個砂輪部件12的定位孔18配合，可以使多個砂輪部件12以正確的位置相互組合。 When the combined grinding wheel 10 of this embodiment is used in the centering process of manufacturing lenses, the grinding surface of the grinding wheel component 12 after joining will show a concave shape, that is, the grinding groove 14. The grinding groove 14 can be used to make the outer diameter, depth, and chamfering of the lens. In order to make the grinding concave after joining The groove 14 is precise. Therefore, as shown in FIG. 1A, there are positioning members 16 on the grinding wheel component 12, which cooperate with the positioning holes 18 of the other grinding wheel component 12, so that a plurality of grinding wheel components 12 can be combined with each other in the correct position.

補充說明的是，關於三個砂輪部件12的研磨面中研磨粒子(例如是鑽粒)之研磨粒度，可以採用相同粒徑的研磨粒子也可以分別採用不同粒徑的研磨粒子，而通常來說，研磨凹槽兩側的斜向研磨面中包括的研磨粒子的粒徑係較研磨凹槽中間相對平坦處的研磨粒子的粒徑來得小，亦即其粒度編號較大。另外，為符合精密的鏡片定芯製程所需，研磨粒子粒徑大小在小於210μm，亦即約當大於#100號的研磨粒子的粒度，時其效果較佳。而當大於#200號研磨粒子的粒度時，其效果更佳。而當研磨粒子的粒徑愈小，其研磨期間損害工件的機會相對愈低，但研磨效率亦相對較差，故研磨粒子的粒徑不宜過小。 It is added that the grinding particle size of the grinding particles (for example, drill particles) in the grinding surfaces of the three grinding wheel components 12 may be the same particle size or different particle size, and generally speaking The particle size of the abrasive particles included in the oblique grinding surfaces on both sides of the grinding groove is smaller than the particle size of the abrasive particles at the relatively flat part in the middle of the grinding groove, that is, the particle size number is larger. In addition, in order to meet the requirements of the precise lens centering process, the particle size of the abrasive particles is less than 210 μm, that is, when the particle size of the abrasive particles is greater than #100, the effect is better. When the particle size is larger than #200, the effect is better. The smaller the particle size of the abrasive particles, the lower the chance of damage to the workpiece during grinding, but the grinding efficiency is relatively poor, so the particle size of the abrasive particles should not be too small.

請參閱圖2，圖2係本發明組合式砂輪10第一實施例之示意圖。組合式砂輪10可以利用第一砂輪部件20、第三砂輪部件24、以及第二砂輪部件22以組裝。第一砂輪部件20具有一個第一研磨面2002，圖中為右向的傾斜面，第二砂輪部件22具有一個第二研磨面2202，圖中為左向的傾斜面，第三砂輪部件24之研磨面係形成第三研磨面2402，圖中為一個平面。第三砂輪部件24係固設於第一砂輪部件20與第二砂輪部件22之間以組合，以使第一研磨面2002、第二研磨面2202及第三研磨面2402依序接連以形成研磨凹槽28。其中，第一研磨面2002與第二研磨面2202可供鏡片倒角時使用，而第三研磨面2402便於研磨鏡片外徑時使用。進一步，只要選用適當的第三砂輪部件24，將第三研磨面2402的寬度與鏡片預計之邊緣厚度相對應，即可一次定位研磨即將鏡片磨出目標樣態，此得提升鏡片生產效率。 Please refer to FIG. 2, which is a schematic diagram of the first embodiment of the combined grinding wheel 10 of the present invention. The combined grinding wheel 10 can be assembled using the first grinding wheel member 20, the third grinding wheel member 24, and the second grinding wheel member 22. The first grinding wheel component 20 has a first grinding surface 2002, which is a right inclined surface, and the second grinding wheel component 22 has a second grinding surface 2202, which is a left inclined surface, and the third grinding wheel component 24 The polishing surface forms a third polishing surface 2402, which is a flat surface in the figure. The third grinding wheel member 24 is fixed between the first grinding wheel member 20 and the second grinding wheel member 22 to be combined, so that the first grinding surface 2002, the second grinding surface 2202, and the third grinding surface 2402 are sequentially connected to form a grinding Groove 28. Among them, the first polishing surface 2002 and the second polishing surface 2202 can be used when the lens is chamfered, and the third polishing surface 2402 is convenient for polishing the outer diameter of the lens. Further, as long as an appropriate third grinding wheel component 24 is selected, the width of the third grinding surface 2402 corresponds to the predicted edge thickness of the lens, then the lens can be polished out of the target shape by one-time positioning grinding, which improves the lens production efficiency.

請參閱圖3，圖3係本發明組合式砂輪10第二實施例之示意圖。組合式砂輪10除了圖2第一實施例中所述之外，組合式砂輪10可僅利用第一砂輪部件20以及第二砂輪部件22以組裝，此實施例之第一砂輪部件20具有第一研磨面2002，第二砂輪部件22具有第二研磨面2202。第一砂輪部件20與第二砂輪部件22組合，以使第一研磨面2002與第二研磨面2202接連以形成研磨凹槽28。 Please refer to FIG. 3, which is a schematic diagram of the second embodiment of the combined grinding wheel 10 of the present invention. In addition to the combination grinding wheel 10 described in the first embodiment of FIG. 2, the combination grinding wheel 10 may use only the first grinding wheel The wheel member 20 and the second grinding wheel member 22 are assembled. The first grinding wheel member 20 of this embodiment has a first grinding surface 2002, and the second grinding wheel member 22 has a second grinding surface 2202. The first grinding wheel member 20 and the second grinding wheel member 22 are combined to connect the first grinding surface 2002 and the second grinding surface 2202 to form a grinding groove 28.

請參閱圖4，圖4係本發明組合式砂輪10第三實施例之示意圖。實際上，研磨凹槽28包括第一研磨面2002及第二研磨面2202之至少一部份，本實施例組合式砂輪10由第一砂輪部件30與第二砂輪部件32組成，第一砂輪部件30之研磨面除了向右傾斜的第一研磨面3002之外，進一步形成與第一研磨面3002低處鄰接之第一平面3004，第二砂輪部件32之研磨面除了向左傾斜的第二研磨面3202之外，進一步形成與第二研磨面3202低處鄰接之第二平面3204。當第一砂輪部件30與第二砂輪部件32組合時，第一平面3004係與第二平面3204為大致共平面，而第一研磨面3002、第一平面3004、第二平面3204、以及第二研磨面3202鄰接以形成研磨凹槽38，而第一研磨面3002與第二研磨面3202之至少一部份，也就是第一平面3004與第二平面3204，為相互水平且相鄰設置。其中，第一研磨面3002與第二研磨面3202可供鏡片倒角時使用，而第一平面3004與第二平面3204所連接成的平面便於研磨鏡片外徑時使用。 Please refer to FIG. 4, which is a schematic diagram of a third embodiment of the combined grinding wheel 10 of the present invention. Actually, the grinding groove 28 includes at least a part of the first grinding surface 2002 and the second grinding surface 2202. In this embodiment, the combined grinding wheel 10 is composed of a first grinding wheel component 30 and a second grinding wheel component 32. The first grinding wheel component In addition to the first polishing surface 3002 inclined to the right, the polishing surface of 30 further forms a first flat surface 3004 adjacent to the lower part of the first polishing surface 3002, and the polishing surface of the second grinding wheel member 32 except for the second polishing inclined to the left In addition to the surface 3202, a second flat surface 3204 adjacent to the lower part of the second polishing surface 3202 is further formed. When the first grinding wheel member 30 and the second grinding wheel member 32 are combined, the first plane 3004 and the second plane 3204 are substantially coplanar, and the first grinding surface 3002, the first plane 3004, the second plane 3204, and the second The grinding surface 3202 is adjacent to form the grinding groove 38, and at least a part of the first grinding surface 3002 and the second grinding surface 3202, that is, the first plane 3004 and the second plane 3204, are horizontal and adjacent to each other. Among them, the first polishing surface 3002 and the second polishing surface 3202 can be used when the lens is chamfered, and the plane formed by the first plane 3004 and the second plane 3204 is convenient for polishing the outer diameter of the lens.

請參閱圖5，圖5係本發明組合式砂輪10第四實施例之示意圖。組合式砂輪除了圖4第三實施例之第一砂輪部件30與第二砂輪部件32之外，進一步包含第三砂輪部件34。第三砂輪部件34之研磨面係形成第三研磨面3402，第三砂輪部件34係設置於第一砂輪部件30與第二砂輪部件32之間以組合，使第一平面3004、第三研磨面3402、以及第二平面3204連接成一個大致的共平面，以使第一研磨面3002、第一平面3004、第三研磨面3402、第二平面3204、以及第二研磨面3202接連以形成研磨凹槽38，而第一研磨面3002、第二研磨面3202之至少一部份，也就是第一平面3004與第二平面3204，會與第三研磨面3402為相互水平。 Please refer to FIG. 5, which is a schematic diagram of a fourth embodiment of the combined grinding wheel 10 of the present invention. The combined grinding wheel further includes a third grinding wheel member 34 in addition to the first grinding wheel member 30 and the second grinding wheel member 32 in the third embodiment of FIG. 4. The grinding surface of the third grinding wheel member 34 forms a third grinding surface 3402. The third grinding wheel member 34 is disposed between the first grinding wheel member 30 and the second grinding wheel member 32 to combine to make the first flat surface 3004 and the third grinding surface 3402 and the second plane 3204 are connected into a substantially coplanar plane, so that the first grinding surface 3002, the first plane 3004, the third grinding surface 3402, the second plane 3204, and the second grinding surface 3202 are connected to form a grinding recess Groove 38 while the first grinding At least a part of the surface 3002 and the second polishing surface 3202, that is, the first flat surface 3004 and the second flat surface 3204, will be horizontal to the third polishing surface 3402.

其中，第一研磨面3002與第二研磨面3202可供鏡片倒角時使用，而第三研磨面3402便於研磨鏡片外徑時使用。進一步，只要選用適當的第三砂輪部件34，使第一平面3004、第三研磨面3402、以及第二平面3204的寬度與鏡片預計之邊緣厚度相對應，即可一次定位研磨即將鏡片磨出目標樣態，此一刀式研磨係使鏡片生產的效益大幅提高。 Among them, the first polishing surface 3002 and the second polishing surface 3202 can be used for lens chamfering, and the third polishing surface 3402 is convenient for polishing the outer diameter of the lens. Further, as long as the appropriate third grinding wheel member 34 is selected so that the widths of the first plane 3004, the third grinding surface 3402, and the second plane 3204 correspond to the expected edge thickness of the lens, the positioning grinding can be performed once the lens is ground out of the target In this way, this one-knife grinding system greatly improves the efficiency of lens production.

補充說明的是，通常研磨倒角所需傾斜的研磨面3002、3202轉向研磨外徑之第三研磨面3402的轉折處為結構最易損壞之處，所以本實施例將轉折處設計在第一砂輪部件30與第二砂輪部件32研磨面的中段而非兩部件(30與34、32與34)的銜接處，可強化此部分的結構強度。 It is added that the turning point of the inclined grinding surfaces 3002 and 3202 required for grinding chamfers to the third grinding surface 3402 of the outer diameter of the grinding is the most vulnerable to the structure, so this embodiment will design the turning point at the first The middle part of the grinding surface of the grinding wheel member 30 and the second grinding wheel member 32 instead of the junction of the two parts (30 and 34, 32 and 34) can strengthen the structural strength of this part.

需提及的是，以上各實施例中的各砂輪部件之研磨面之接觸處得選擇性地設置有一隔槽，如圖6繪述者，即為一例，將不分別予以贅述之。請參閱圖6，圖6係本發明另一組合式砂輪40實施例之示意圖。於本實施例中，組合式砂輪40係利用於製造鏡片之定芯製程中。組合式砂輪40係包含第一輪型砥石50、第二輪型砥石52、以及第三輪型砥石54，此實施例係由第一輪型砥石50、第二輪型砥石52、以及第三輪型砥石54以側面相鄰貼附的組成組合式砂輪40，使周緣(外沿)的研磨面組成研磨凹槽58。第一輪型砥石50之研磨面係包括右向傾斜研磨面5002的研磨斜面、以及與右向傾斜研磨面5002低處所鄰接之第一研磨平面5004的研磨平面，第二輪型砥石52之研磨面係包括第二研磨平面5202的研磨平面，第三輪型砥石54之研磨面係包括左向傾斜研磨面5402的研磨斜面、以及與左向傾斜研磨面5402低處所鄰接之第三研磨平面5404的研磨平面。其中實務上，第一輪型砥石50之研磨斜面及第三輪型砥石54之研磨斜面分別相對於第二輪型砥石52研磨平面的傾斜角可為相異，也就是右向傾斜研磨面5002與左向傾斜研磨面5402的傾斜角可以是不一樣的。 It should be mentioned that the contact point of the grinding surface of each grinding wheel component in the above embodiments may be selectively provided with a partition groove, as depicted in FIG. 6, which is an example, and will not be repeated separately. Please refer to FIG. 6, which is a schematic diagram of another embodiment of the combined grinding wheel 40 of the present invention.

第一輪型砥石50、第二輪型砥石52與第三輪型砥石54鄰接組合，以使右向傾斜研磨面5002、第一研磨平面5004、第二研磨平面5202、第三研磨平面5404、以及左向傾斜研磨面5402依序連接形成研磨凹槽58，其中第一研磨平面5004、第二研磨平面5202、以及第三研磨平面5404形成共平面。其中，右向傾斜研磨面5002與左向傾斜研磨面5402可供鏡片倒角時使用，而第二研磨平面5202便於研磨鏡片外徑時使用。進一步，只要選用適當的第二輪型砥石52，使第一研磨平面5004、第二研磨平面5202、以及第三研磨平面5404的寬度與鏡片預計之邊緣厚度相對應，即可一次定位研磨即將鏡片磨出目標樣態。 The first round type whetstone 50, the second round type whetstone 52 and the third round type whetstone 54 are adjacently combined, so that the rightward inclined grinding surface 5002, the first grinding surface 5004, the second grinding surface 5202, the third grinding surface 5404, And the left-facing inclined grinding surface 5402 is connected in sequence to form a grinding groove 58, wherein the first grinding plane 5004, the second grinding plane 5202, and the third grinding plane 5404 form a coplanar plane. Among them, the right inclined polishing surface 5002 and the left inclined polishing surface 5402 can be used for lens chamfering, and the second grinding plane 5202 is convenient for grinding the outer diameter of the lens. Further, as long as an appropriate second-round type whetstone 52 is selected so that the widths of the first grinding plane 5004, the second grinding plane 5202, and the third grinding plane 5404 correspond to the predicted edge thickness of the lens, the lens can be positioned and polished at one time. Grind out the target.

補充說明的是，通常研磨倒角所需的傾斜研磨面5002、5402轉向研磨外徑之研磨平面5202的轉折處為結構最易損壞之處，所以本實施例將轉折處設計在第一輪型砥石50與第三輪型砥石54研磨面的中段而非兩部件(50與52、52與54)的銜接處，可強化此部分的結構強度。 It is added that the turning point of the inclined grinding surfaces 5002 and 5402 required to grind the chamfer to the grinding plane 5202 of the grinding outer diameter is the most susceptible to damage to the structure, so this embodiment design the turning point in the first round type The middle part of the grinding surface of the whetstone 50 and the third wheel whetstone 54 instead of the junction of the two parts (50 and 52, 52 and 54) can strengthen the structural strength of this part.

第一輪型砥石50、第二輪型砥石52、以及第三輪型砥石54之研磨面中研磨粒子之研磨粒度，可以是相同粒徑大小的研磨粒子，也可以採用不同粒徑大小的研磨粒子，為符合精密的鏡片定芯製程所需，研磨面中的研磨粒子之粒徑大小係以小於210μm為佳，相當於#100的研磨粒度為佳，由此範圍粒徑大小之研磨粒子相互組合為佳，而增加砥石粒度大小的選擇，甚至選擇不同硬度之研磨粒子，有助於縮短加工時間，且同步提升良率。 The grinding particle size of the grinding particles in the grinding surfaces of the first-round type whetstone 50, the second-round type whetstone 52, and the third-round type whetstone 54 may be the same particle size or different sizes. Particles, in order to meet the requirements of the precise lens centering process, the particle size of the abrasive particles in the grinding surface is preferably less than 210μm, which is equivalent to the grinding particle size of #100. The combination is better, and the choice of increasing the size of the whetstone particle size, or even choosing abrasive particles of different hardness, helps to shorten the processing time and simultaneously improve the yield.

進一步說明，較佳的還可採用分隔槽，分隔槽以圖例之第一溝60以及第二溝62來說明，可以利用於圖5或圖6實施例中，為求說明簡潔，以下僅用圖6說明而並非限制僅用於圖6實施例。第一研磨平面5004與第二研磨平面5202連接處還可具有第一溝60，第二研磨平面5202與第三研磨平面5404連接處也還可具有第二溝62，第一溝60以及第二溝62皆是所述之分隔槽。在各砥石50、52、54製做研磨面之初，需將研磨粒子設置在研磨面上，但若不慎使部分研磨粒子污染砥石50、52、54的貼合面，則會造成貼合的精度不足，因此利用第一溝60、第二溝62可以防止污染砥石50、52、54的貼合面，此外，也可做為不同粒度大小研磨面的分界線。 To further explain, it is also preferable to use a dividing groove. The dividing groove is illustrated by the first groove 60 and the second groove 62 in the figure. It can be used in the embodiment of FIG. 5 or FIG. 6. The following is only illustrated with FIG. 6 and is not limited to the embodiment of FIG. 6. The connection between the first grinding plane 5004 and the second grinding plane 5202 can also have a first groove 60, and the connection between the second grinding plane 5202 and the third grinding plane 5404 can also have a second groove 62, the first groove 60 and the second The grooves 62 are all the dividing grooves mentioned above. At the beginning of each grindstone 50, 52, 54 as a grinding surface, the abrasive particles need to be placed on the grinding surface, but if some of the abrasive particles inadvertently contaminate the grindstone 50, 52, 54 bonding surface, it will cause bonding The accuracy is insufficient, so the first groove 60 and the second groove 62 can prevent contamination of the bonding surfaces of the whetstones 50, 52, and 54. In addition, they can also be used as the dividing lines of the grinding surfaces with different particle sizes.
