Description
本發明是有關於一種滾輪之加工裝置與加工方法，且特別是有關於一種滾輪微溝槽之加工裝置與加工方法。The invention relates to a processing device and a processing method for a roller, and in particular to a processing device and a processing method for a roller microgroove.
在平面顯示器的發展中，顯示器的尺寸大型化為重要的趨勢之一。因此，為因應平面顯示器的大型化發展，提供顯示面板背光源之大型背光模組的製作技術也成為研究開發的重心。In the development of flat panel displays, the size of displays has become one of the important trends. Therefore, in order to cope with the large-scale development of flat panel displays, the fabrication technology of large backlight modules that provide backlights for display panels has also become the focus of research and development.
在液晶顯示器之背光模組中，俗稱稜鏡片的光學增亮膜(Brightness Enhancement Film；BEF)係現今背光模組中相當重要的零組件。然，光學增亮膜相當昂貴，在一背光模組中，光學增亮膜的成本約佔整個背光模組之成本的40%左右。目前，在光學增亮膜之製作技術中，通常係利用滾輪來進行光學增亮膜之表面微結構的製作。In the backlight module of the liquid crystal display, the Brightness Enhancement Film (BEF), commonly known as the cymbal film, is a very important component in the backlight module. However, the optical brightness enhancement film is quite expensive. In a backlight module, the cost of the optical brightness enhancement film accounts for about 40% of the cost of the entire backlight module. At present, in the production technology of an optical brightness enhancement film, a roller is used to fabricate the surface microstructure of an optical brightness enhancement film.
請參照第1圖，其係繪示一般製作光學增亮片時的裝置示意圖。製作光學增亮膜114時，先提供滾輪100，其中滾輪100之圓柱的側表面102上凸設有數個整齊排列的鋸齒結構104，且相鄰二鋸齒結構104之間設有溝槽106。接著，將滾輪100水平壓置於高分子材料層108之表面116上，並使滾輪100之表面102與高分子材料層108之表面116緊密接合。然後，滾動滾輪100，以將滾輪100之表面102上的鋸齒結構106轉印至高分子材料層108之表面116上，其中滾輪100上的鋸齒結構106在高分子材料層108之表面116 上製造出溝槽112，而滾輪100上的溝槽106則在高分子材料層108之表面116上製造出鋸齒結構110。Please refer to FIG. 1 , which is a schematic diagram of a device generally used for fabricating an optical brightening sheet. When the optical brightness enhancement film 114 is formed, the roller 100 is first provided. The cylindrical side surface 102 of the roller 100 is convexly provided with a plurality of neatly arranged sawtooth structures 104, and a groove 106 is disposed between the adjacent two sawtooth structures 104. Next, the roller 100 is horizontally pressed onto the surface 116 of the polymer material layer 108, and the surface 102 of the roller 100 is brought into close contact with the surface 116 of the polymer material layer 108. Roller 100 is then rolled to transfer sawtooth structure 106 on surface 102 of roller 100 onto surface 116 of polymeric material layer 108, wherein sawtooth structure 106 on roller 100 is on surface 116 of polymeric material layer 108. A groove 112 is formed thereon, and the groove 106 on the roller 100 produces a sawtooth structure 110 on the surface 116 of the layer of polymeric material 108.
目前，在製作滾輪100時，通常係利用鑽石刀具來切削滾輪100的表面102，以在滾輪100之表面102製作出溝槽106，進而在滾輪100之表面102上定義出鋸齒結構104。然而，隨著平面顯示器之尺寸的大型化，背光模組之尺寸及其內之光學增亮膜的尺寸也日益增加，因此滾輪100的尺寸也隨之朝大型化的趨勢發展。如此一來，滾輪100之表面102的微溝槽106的加工量勢必大幅增加，且加工時間也越來越長。再加上，滾輪100之表面102上的結構特徵相當細微。Currently, in the fabrication of the roller 100, a diamond cutter is typically used to cut the surface 102 of the roller 100 to create a groove 106 in the surface 102 of the roller 100, thereby defining a sawtooth structure 104 on the surface 102 of the roller 100. However, as the size of the flat panel display has increased, the size of the backlight module and the size of the optical brightness enhancing film therein have also increased, and the size of the roller 100 has also increased toward a large size. As a result, the processing amount of the micro-grooves 106 of the surface 102 of the roller 100 is bound to increase greatly, and the processing time is also longer. Additionally, the structural features on the surface 102 of the roller 100 are rather subtle.
由於在傳統製造技術中，係採用單把刀具來進行滾輪表面的微溝槽切削，然面對越來越大量的微細溝槽加工，不僅加工時間無法縮減，鑽石刀具的磨耗速度也大增。因此，不僅不利於量產，更導致滾輪的製作成本提高。而且，由於鑽石刀具的快速磨耗，更會影響滾輪表面之微溝槽結構的均勻度，進而影響光學增亮膜的製作。In the traditional manufacturing technology, a single tool is used to perform micro-groove cutting on the surface of the roller, and in the face of more and more fine groove processing, not only the processing time cannot be reduced, but also the wear speed of the diamond tool is greatly increased. Therefore, not only is it not conducive to mass production, but also the manufacturing cost of the roller is increased. Moreover, due to the rapid wear of the diamond cutter, the uniformity of the micro-groove structure on the surface of the roller is affected, which in turn affects the fabrication of the optical brightness enhancement film.
因此，本發明之目的就是在提供一種滾輪微溝槽之加工裝置，其刀座上同時設有粗車刀具與精車刀具，以先後執行同一道溝槽的加工，故可降低精車刀具的損耗。Therefore, the object of the present invention is to provide a processing device for a roller micro-groove, which is provided with a roughing tool and a finishing tool at the same time to perform the same groove processing in sequence, thereby reducing the precision of the cutting tool. loss.

本發明之又一目的是在提供一種滾輪微溝槽之加工方法，其先利用粗車刀具去除大量材料以在滾輪表面上粗略形成一微溝槽，再利用精車刀具來精修此一微溝槽的表面，因此可減緩精車刀具的磨耗，而可大幅提升滾輪微溝槽之加工可靠度，並可提高微溝槽的結構精確度。Another object of the present invention is to provide a method for processing a micro-groove of a roller, which first uses a roughing tool to remove a large amount of material to roughly form a micro-groove on the surface of the roller, and then uses a finishing tool to refine the micro-groove. The surface of the groove can reduce the wear of the finishing tool, and can greatly improve the processing reliability of the roller micro-groove and improve the structural precision of the micro-groove.
本發明之再一目的是在提供一種滾輪微溝槽之加工方法，其可在同一切削道次下，同時完成去除大量材料以形成微溝槽、以及微溝槽表面之精修，因此可大大地減少切削道次，而可縮減滾輪加工之切削時間，進而可提升滾輪微溝槽之加工效率。A further object of the present invention is to provide a method for processing a roller micro-groove which can simultaneously remove a large amount of material to form micro-grooves and fine-finish the surface of the micro-grooves under the same cutting pass, thereby greatly The ground cutting time is reduced, and the cutting time of the roller processing can be reduced, thereby improving the processing efficiency of the roller micro-groove.

In order to make the description of the present invention more detailed and complete, reference is made to the following description and in conjunction with the drawings of Figures 2 through 4.
請參照第2圖，其係繪示依照本發明一較佳實施例的一種滾輪微溝槽之加工裝置的立體示意圖。在一示範實施例中，滾輪微溝槽之加工裝置200可用以在一滾輪226(請先參照第3圖)之表面上進行切削加工而定義出微溝槽結構，其中此滾輪226可為製作光學膜片，例如光學增亮膜，的光學膜片加工滾輪。滾輪微溝槽之加工裝置200主要包括刀座202以及至少二刀具，例如粗車刀具204與精車刀具206，其中這些刀具之刀鼻半徑均不相同。舉例而言，粗車刀具204之刀鼻半徑比精車刀具206之刀鼻半徑大。刀座202之同一側上設有數個刀具固定口，例如刀具固定口208與210，其中這些刀具固定口之數量係對應於滾輪微溝槽之加工裝置200的刀具數量，因此這些刀具可分別對應固設在刀座202之同一側上的刀具固定口中，因而這些刀具係以並排方式設置在刀座上202。舉例而言，粗車刀具204與精車刀具206分別***並固定在刀具固定口208與210之中，且呈並排排列狀。操作滾輪微溝槽之加工裝置200來對滾輪226 進行表面微溝槽加工時，係將此滾輪226設置在這些刀具，例如粗車刀具204與精車刀具206，之正前方，因此這些刀具可同時對滾輪之表面進行切削處理，而可縮短加工時間。Please refer to FIG. 2 , which is a perspective view of a processing device for a micro groove of a roller according to a preferred embodiment of the present invention. In an exemplary embodiment, the roller microgroove processing apparatus 200 can be used to define a micro-trench structure by performing a cutting process on a surface of a roller 226 (refer to FIG. 3 first), wherein the roller 226 can be fabricated. An optical film processing roller such as an optical film, such as an optical brightness enhancement film. The roller micro-groove processing apparatus 200 mainly includes a tool holder 202 and at least two tools, such as a roughing tool 204 and a finishing tool 206, wherein the cutters have different nose nose radii. For example, the roughing tool 204 has a nose radius that is greater than the nose radius of the finishing tool 206. A plurality of tool fixing ports, such as tool fixing ports 208 and 210, are provided on the same side of the tool holder 202, wherein the number of the tool fixing ports corresponds to the number of tools of the processing device 200 of the roller microgrooves, so that the tools can respectively correspond to They are fixed in the tool holders on the same side of the holder 202, so that the tools are disposed on the holder 202 in a side-by-side manner. For example, the roughing tool 204 and the finishing tool 206 are respectively inserted and fixed in the tool fixing ports 208 and 210, and are arranged side by side. Operating the roller micro-groove processing device 200 to the roller 226 When the surface micro-groove processing is performed, the roller 226 is disposed in front of the cutters, such as the roughing tool 204 and the finishing cutter 206, so that the cutters can simultaneously cut the surface of the roller and shorten the processing. time.
在一實施例中，這些刀具之材料相同，例如粗車刀具204與精車刀具206之材料相同，其中粗車刀具204與精車刀具206均可為鑽石刀具。在另一些實施例中，滾輪微溝槽之加工裝置200的所有刀具的材料彼此均不相同，例如粗車刀具204採用碳鋼刀具，而精車刀具206則採用鑽石刀具，以確保所切削之滾輪微溝槽結構的精確度。由於鑽石刀具相當昂貴，但具有高硬度，因此粗車刀具204採用非鑽石刀具，且精車刀具206採用鑽石刀具的情況下，可兼顧成本與滾輪微溝槽結構的精確度。在其他實施例中，當滾輪微溝槽之加工裝置包括三把以上的刀具時，可一部分之刀具採用相同的材料，而另一部分的刀具則採用不同材料。In one embodiment, the materials of the cutters are the same, for example, the roughing tool 204 is the same material as the finishing tool 206, and both the roughing tool 204 and the finishing tool 206 can be diamond tools. In other embodiments, the materials of all the tools of the roller microgroove processing device 200 are different from each other, for example, the roughing tool 204 uses a carbon steel tool, and the finishing tool 206 uses a diamond tool to ensure the cutting. The accuracy of the roller micro-groove structure. Since the diamond tool is quite expensive, but has a high hardness, the roughing tool 204 uses a non-diamond tool, and the finishing tool 206 uses a diamond tool to balance the cost with the accuracy of the roller micro-groove structure. In other embodiments, when the processing device for the roller microgrooves includes more than three tools, one portion of the tool may be of the same material and the other portion of the tool may be of a different material.
選擇性地，如第2圖之示範實施例所示，刀座202可進一步包括基座212與216、以及滑動件218，其中刀具固定口208設置在基座212中，且刀具固定口210則設置在另一基座216中，這些刀具固定口208與210均位於刀座202之同一側。因而，位於刀具固定口208中之粗車刀具204係設置在基座212上，而位於刀具固定口210中之精車刀具206則係設置在另一基座216上。基座212至少設有滑槽214，且滑動件218嵌設於基座212的滑槽214中，其中滑動件218可相對於基座212進行方向222的滑動。滑動件218則包括有滑軌220，且此滑軌220嵌設於基座216之底部中而與基座216結合，其中基座216可沿著滑軌220而滑 動，如此一來，使得基座216可相對於另一基座212進行另一方向224的滑動。而由於滑軌220嵌設於基座216之底部，因此當滑動件218相對於基座212進行方向222的滑動，意味著與滑軌220結合之基座216也會隨著滑動件218的滑動而相對於基座212進行方向222的滑動。在此示範實施例中，方向222不同於方向224，且方向222較佳係與方向224垂直。因此，在此實施例中，粗車刀具204在刀座202上的位置係固定不動，而精車刀具206在此刀座202上的位置係可調整而非固定不動，因此可對精車刀具206進行位置的微調。然，在其他實施例中，所有的刀具在刀座上的位置均可調整變動。Optionally, as shown in the exemplary embodiment of FIG. 2, the holder 202 may further include bases 212 and 216, and a slider 218, wherein the cutter fixing opening 208 is disposed in the base 212, and the cutter fixing opening 210 is Disposed in the other base 216, the cutter fixing ports 208 and 210 are located on the same side of the seat 202. Thus, the roughing tool 204 located in the tool fixing opening 208 is disposed on the base 212, and the finishing tool 206 located in the tool fixing opening 210 is disposed on the other base 216. The base 212 is at least provided with a sliding slot 214 , and the sliding member 218 is embedded in the sliding slot 214 of the base 212 , wherein the sliding member 218 can slide in the direction 222 relative to the base 212 . The sliding member 218 includes a sliding rail 220, and the sliding rail 220 is embedded in the bottom of the base 216 to be coupled with the base 216. The base 216 can slide along the sliding rail 220. In this manner, the base 216 can be slid in the other direction 224 relative to the other base 212. Since the slide rail 220 is embedded in the bottom of the base 216, when the slide member 218 slides in the direction 222 with respect to the base 212, it means that the base 216 coupled with the slide rail 220 also slides along with the slide member 218. The direction 222 is slid relative to the base 212. In the exemplary embodiment, direction 222 is different from direction 224, and direction 222 is preferably perpendicular to direction 224. Therefore, in this embodiment, the position of the roughing tool 204 on the seat 202 is fixed, and the position of the finishing tool 206 on the seat 202 can be adjusted rather than fixed, so that the finishing tool can be used. 206 performs fine-tuning of the position. However, in other embodiments, all of the tools can be adjusted in position on the tool holder.
如第3圖所示，在此示範實施例中，滾輪226係設置在粗車刀具204與精車刀具206的正前方，以利粗車刀具204與精車刀具206同時對滾輪226進行表面加工，因而方向222所指較佳係為精車刀具206朝滾輪226垂直前進或垂直後退的方向。此外，粗車刀具204與精車刀具206在刀座202上係呈並排排列，因而方向224所指較佳係為精車刀具206朝粗車刀具204側向垂直前進或側向垂直後退的方向。As shown in FIG. 3, in the exemplary embodiment, the roller 226 is disposed directly in front of the roughing tool 204 and the finishing tool 206, so that the roughing tool 204 and the finishing tool 206 simultaneously surface the roller 226. Therefore, the direction 222 is preferably a direction in which the finishing tool 206 is vertically or vertically retracted toward the roller 226. In addition, the roughing tool 204 and the finishing tool 206 are arranged side by side on the seat 202, so that the direction 224 is preferably a direction in which the finishing tool 206 is moved vertically toward the roughing tool 204 or laterally vertically backward. .
在一些實施例中，當滾輪微溝槽之加工裝置包括三把以上的刀具時，刀座202可包括一基座212、數個滑動件218以及數量與滑動件218相同之數個基座216，其中基座212設有數量與基座216及滑動件218相同的滑槽214，滑動件218分別對應嵌設在這些滑槽214中。每個滑動件218均包括一滑軌220，而這些滑軌220則分別對應嵌設在基座216之底部中，且每個基座216可沿著滑軌220而滑動，如同上 述示範實施例之刀座配置。相同地，每個滑動件218可相對於基座212進行方向222的滑動，而使每個基座216相對於基座212進行方向222的滑動，且每個基座216可相對於另一基座212進行另一方向224的滑動。其中，方向222不同於方向224，且方向222較佳係與方向224垂直。同樣地，基座212與每個基座216均設有一刀具固定口，這些刀具固定口均位於刀座202之同一側，而每個刀具分別對應設置且固定在這些刀具固定口中。藉由可滑動之滑動件218與基座216的設計，使得設在基座216上的每把刀具可單獨調整定位，且可提供不同切削目的，更可縮短切削時間。In some embodiments, when the roller microgroove processing apparatus includes more than three cutters, the blade holder 202 can include a base 212, a plurality of sliders 218, and a plurality of bases 216 having the same number as the sliders 218. The pedestal 212 is provided with the same number of sliding slots 214 as the base 216 and the sliding member 218, and the sliding members 218 are respectively embedded in the sliding slots 214. Each of the sliding members 218 includes a sliding rail 220, and the sliding rails 220 are respectively embedded in the bottom of the base 216, and each of the bases 216 can slide along the sliding rail 220, as shown above. The tool holder configuration of the exemplary embodiment. Similarly, each slider 218 can slide in a direction 222 relative to the base 212, causing each base 216 to slide in a direction 222 relative to the base 212, and each base 216 can be relative to another base The seat 212 performs sliding in the other direction 224. Wherein, direction 222 is different from direction 224, and direction 222 is preferably perpendicular to direction 224. Similarly, the base 212 and each of the bases 216 are provided with a tool fixing port, and the tool fixing ports are located on the same side of the tool holder 202, and each tool is correspondingly disposed and fixed in the tool fixing ports. By the design of the slidable slider 218 and the base 216, each tool provided on the base 216 can be individually adjusted and positioned to provide different cutting purposes and shorten the cutting time.
然而，值得注意的一點是，在本發明之其他實施例中，滾輪微溝槽之加工裝置的刀座可為單一基座結構，而並不配備有數個位置可相對移動之基座。However, it is worth noting that in other embodiments of the present invention, the tool holder of the roller microgroove processing apparatus may be a single base structure and is not equipped with a plurality of positions that are relatively movable.
請再次參照第2圖與第3圖，在此示範實施例中，分別固定在刀座202之刀具固定口208與210中的粗車刀具204與精車刀具206對於欲進行加工之物件，例如滾輪226，分別具有一切深，其中粗車刀具204之切深大於精車刀具206之切深。在一實施例中，每個刀具均具有切深，且每個刀具之切深均不相同。在一較佳實施例中，具有較大切深之刀具，其刀鼻半徑較大；而具有較小切深之刀具，其刀鼻半徑較小。Referring again to FIGS. 2 and 3, in the exemplary embodiment, the roughing tool 204 and the finishing tool 206 respectively fixed in the tool fixing ports 208 and 210 of the holder 202 are for the object to be processed, for example, The rollers 226 each have a deep depth, wherein the roughing tool 204 has a depth of cut greater than the depth of cut of the finishing tool 206. In one embodiment, each tool has a depth of cut and each tool has a different depth of cut. In a preferred embodiment, a tool having a larger depth of cut has a larger nose radius; and a tool having a smaller depth of cut has a smaller nose radius.
在一較佳實施例中，滾輪微溝槽之加工裝置的所有刀具係依照每個刀具所具有之切深的大小，而依順序排列。一般而言，在一刀座中，第一個對滾輪進行切削加工的刀具係設置在所有刀具固定口之第一個，且設於此第一個刀具固定口 之刀具的切深是所有刀具中最大的；而設置在緊接於第一個刀具固定口的第二個刀具固定口中之刀具的切深則是所有刀具中次大的；其餘刀具按照上述規則依序設置。舉例而言，如第2圖與第3圖所示，在粗車刀具204與精車刀具206中，粗車刀具204之刀鼻半徑較大且切深較大，因此粗車刀具204設置在刀座202之第一個刀具固定口208中；另一方面，精車刀具206之刀鼻半徑較小且切深較小，因此精車刀具206設置在刀座202之第一個刀具固定口208的下一個刀具固定口210中。在一較佳實施例中，這些刀具中具有最小切深的刀具較佳係採用鑽石刀具，以利精確修整已形成之微溝槽的表面。In a preferred embodiment, all of the tooling of the roller microgroove processing device is arranged in sequence according to the depth of cut of each tool. Generally, in a tool holder, the first tool for cutting the roller is set at the first of all the tool fixing ports, and is disposed at the first tool fixing port. The cutting depth of the tool is the largest of all the tools; the cutting depth of the tool set in the second tool fixing port next to the first tool fixing port is the second largest among all the tools; the remaining tools follow the above rules Set in order. For example, as shown in FIGS. 2 and 3, in the roughing tool 204 and the finishing tool 206, the roughing tool 204 has a larger nose radius and a larger depth of cut, so the roughing tool 204 is disposed at The first tool fixing port 208 of the tool holder 202; on the other hand, the finishing tool 206 has a smaller nose radius and a smaller depth of cut, so the finishing tool 206 is disposed at the first tool fixing port of the holder 202. The next tool holder 210 of the 208 is in place. In a preferred embodiment, the tool having the smallest depth of cut in these tools is preferably a diamond cutter to precisely trim the surface of the formed micro-groove.
請參照第4圖，其係繪示依照本發明一較佳實施例的一種滾輪微溝槽之加工方法的實施示意圖，且請一併參照第2圖與第3圖。在一示範實施例中，可先提供滾輪微溝槽之加工裝置200。同時，提供滾輪226，並使滾輪226之側表面正對滾輪微溝槽之加工裝置200的粗車刀具204與精車刀具206，其中精車刀具206與滾輪226之側表面之間的距離略小於粗車刀具204與滾輪226之側表面之間的距離。由於欲定義在滾輪226表面上之相鄰二溝槽232與234之間的間距228通常遠小於粗車刀具204與精車刀具206之間的距離230，因此在一實施例中，粗車刀具204對快速滾動之滾輪226進行數次切削，而在滾輪226側表面上形成數個粗具雛形的微溝槽232後，設在粗車刀具204之後的精車刀具206才開始對第一個形成之微溝槽232的表面進行切削，而精修此微溝槽232的表面，進而完成結構完備之微溝槽234。由 於粗車刀具204之切深大於精車刀具206，且粗車刀具204之刀鼻半徑大於精車刀具206之刀鼻半徑，因此先利用粗車刀具204移除滾輪226之一表面局部區域上的大量材料，而在滾輪226表面上形成僅具雛形之微溝槽232，隨後再利用精車刀具206精雕此僅具雛形之微溝槽232，而將此僅具雛形之微溝槽232修成符合所需結構的微溝槽234。如此一來，可降低精車刀具206之耗損，而可延長精車刀具206之使用壽命，更可縮減製程成本。此外，由於滾輪226之微溝槽234製作中，大多數的製程時間中係同時利用粗車刀具204來去除形成微溝槽234時所需移除之滾輪材料中的大部分材料，與利用精車刀具206來精修僅具雛形之微溝槽232的表面，因此可大大地縮短製程時間。Referring to FIG. 4, a schematic diagram of a method for processing a microgroove of a roller according to a preferred embodiment of the present invention is shown. Referring to FIG. 2 and FIG. 3 together. In an exemplary embodiment, the processing device 200 for the roller micro-grooves may be provided first. At the same time, the roller 226 is provided, and the side surface of the roller 226 faces the roughing tool 204 and the finishing tool 206 of the processing device 200 of the roller microgroove, wherein the distance between the side surface of the finishing tool 206 and the roller 226 is slightly It is smaller than the distance between the roughing tool 204 and the side surface of the roller 226. Since the spacing 228 between adjacent two grooves 232 and 234 to be defined on the surface of the roller 226 is typically much smaller than the distance 230 between the roughing tool 204 and the finishing tool 206, in one embodiment, the roughing tool 204 performs a number of cuttings on the fast rolling roller 226, and after forming a plurality of coarse-shaped micro-grooves 232 on the side surface of the roller 226, the finishing cutter 206 disposed after the roughing tool 204 starts to the first one. The surface of the formed micro-trench 232 is cut to finish the surface of the micro-trench 232, thereby completing the well-formed micro-grooves 234. by The depth of the roughing tool 204 is greater than that of the finishing tool 206, and the nose radius of the roughing tool 204 is greater than the radius of the nose of the finishing tool 206. Therefore, the roughing tool 204 is used to remove a portion of the surface of the roller 226. A large amount of material is formed, and only the micro-grooves 232 are formed on the surface of the roller 226, and then the micro-grooves 232 are only engraved by the finishing cutter 206, and the micro-grooves 232 are only shaped. A micro-groove 234 conforming to the desired structure is fabricated. In this way, the wear of the finishing tool 206 can be reduced, and the service life of the finishing tool 206 can be extended, and the process cost can be reduced. In addition, since the micro-grooves 234 of the roller 226 are fabricated, most of the process time utilizes the roughing tool 204 to remove most of the material of the roller material that needs to be removed when forming the micro-grooves 234, The vehicle cutter 206 refines the surface of the micro-trench 232, which is only rudimentary, thereby greatly reducing the process time.
在另一實施例中，若所需之滾輪微溝槽之間距等於粗車刀具204與精車刀具206之間的距離230時，則在利用粗車刀具204進行一切削步驟而在滾輪226表面形成僅具雛形之微溝槽232後，緊接著的下一道切削步驟即可同時利用精車刀具206來精修此微溝槽232而完成微溝槽234，並利用粗車刀具204在滾輪226表面形成另一僅具雛形之微溝槽232。In another embodiment, if the required distance between the roller micro-grooves is equal to the distance 230 between the roughing tool 204 and the finishing tool 206, then a cutting step is performed with the roughing tool 204 on the surface of the roller 226. After forming the only micro-grooves 232, the next subsequent cutting step can simultaneously refine the micro-grooves 232 using the finishing tool 206 to complete the micro-grooves 234, and utilize the roughing tool 204 on the rollers 226. The surface forms another micro-groove 232 that is only shaped.
最後，當粗車刀具204完成整個滾輪226之切削程序後，後續即單獨利用精車刀具206來進行切削，以完成前方尚未修整之微溝槽232的表面精修，而完成滾輪226上之所有微溝槽234。因此，從上述實施例可知，每個符合所需結構的微溝槽需經至少二不同刀具所進行之至少二道切削。Finally, after the roughing tool 204 completes the cutting process of the entire roller 226, the finishing tool 206 is used to perform the cutting separately to complete the surface finishing of the untrimmed micro groove 232, and all the rollers 226 are completed. Micro-grooves 234. Thus, it will be apparent from the above-described embodiments that each of the microgrooves conforming to the desired configuration requires at least two passes of at least two different cutters.
由上述示範實施例可知，本發明之實施例之一優點就是 因為滾輪微溝槽之加工裝置的刀座上同時設有粗車刀具與精車刀具，以先後執行同一道溝槽的加工，故可降低精車刀具的損耗。It is apparent from the above exemplary embodiments that one of the advantages of the embodiment of the present invention is Since the roughing tool and the finishing tool are simultaneously arranged on the seat of the processing device of the roller micro-groove, the same groove processing is performed successively, so that the loss of the finishing tool can be reduced.
由上述示範實施例可知，本發明之實施例的另一優點就是因為滾輪微溝槽之加工裝置之精車刀具的使用壽命增加，因此可減少滾輪微溝槽之加工成本。It can be seen from the above exemplary embodiments that another advantage of the embodiment of the present invention is that the processing cost of the roller microgroove can be reduced because the service life of the finishing tool of the roller microgroove processing device is increased.
由上述示範實施例可知，本發明之實施例的又一優點就是因為滾輪微溝槽之加工方法係先利用粗車刀具去除大量材料以在滾輪表面上粗略形成一微溝槽，再利用精車刀具來精修此一微溝槽的表面，因此可減緩精車刀具的磨耗，而可大幅提升滾輪微溝槽之加工可靠度，並可提高微溝槽的結構精確度。It can be seen from the above exemplary embodiments that another advantage of the embodiment of the present invention is that the processing method of the roller micro-groove is to first remove a large amount of material by using a roughing tool to roughly form a micro-groove on the surface of the roller, and then use the finishing vehicle. The tool refines the surface of the micro-groove, so that the wear of the finishing tool can be slowed down, the machining reliability of the micro-groove of the roller can be greatly improved, and the structural precision of the micro-groove can be improved.
由上述示範實施例可知，本發明之實施例的再一優點就是因為滾輪微溝槽之加工方法可在同一切削道次下，同時完成去除大量材料以形成微溝槽、以及微溝槽表面之精修，因此可大大地減少切削道次，而可縮減滾輪加工之切削時間，進而可提升滾輪微溝槽之加工效率。It can be seen from the above exemplary embodiments that another advantage of the embodiment of the present invention is that the processing method of the roller micro-groove can simultaneously remove a large amount of material to form the micro-groove and the surface of the micro-groove under the same cutting pass. Intensive, so the cutting pass can be greatly reduced, and the cutting time of the roller processing can be reduced, thereby improving the processing efficiency of the roller microgroove.
雖然本發明已以一較佳實施例揭露如上，然其並非用以限定本發明，任何在此技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作各種之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。Although the present invention has been described above in terms of a preferred embodiment, it is not intended to limit the invention, and it is intended that various modifications may be made without departing from the spirit and scope of the invention.
