Additionally, the abrasive particles comprise a Vickers hardness of at least about 5 GPa. In one embodiment, the abrasive particles can be present in an amount from about 50 wt% to about 80 wt% of the abrasive tool.

該基體材料可以包括一粘合劑，例如一酚醛樹脂或一環氧樹脂，以及一兩親性嵌段共聚物。在一實例中，該基體材料可以包括從約70 wt%至約95 wt%的粘合劑以及從約5 wt%至約30 wt%的兩親性嵌段共聚物。The matrix material may comprise a binder such as a phenolic resin or an epoxy resin, and an amphiphilic block copolymer. In an example, the matrix material can include from about 70 wt% to about 95 wt% binder and from about 5 wt% to about 30 wt% amphiphilic block copolymer.

該兩親性嵌段共聚物可以包括至少兩個嵌段並且可以包括多個嵌段，該等嵌段包括：聚(甲基丙烯酸甲酯)、聚苯乙烯、聚丁二烯、或它們的任何組合。在一實例中，該兩親性嵌段共聚物可以是一種二嵌段共聚物或一種三嵌段共聚物。The amphiphilic block copolymer may comprise at least two blocks and may comprise a plurality of blocks comprising: poly(methyl methacrylate), polystyrene, polybutadiene, or Any combination. In one example, the amphiphilic block copolymer can be a diblock copolymer or a triblock copolymer.

圖2包括一示例性二嵌段共聚物200的圖示。該二嵌段共聚物200可以包括嵌段202和204。另外，該二嵌段共聚物可以包括由嵌段202和204組成的重複單元，使得在嵌段204之後是嵌段202並且在嵌段202之後是嵌段204。該嵌段202可以包括一與嵌段204不同的聚合物，並且這樣，嵌段202的特性可以與嵌段204的特性不同。FIG. 2 includes an illustration of an exemplary diblock copolymer 200. The diblock copolymer 200 can include blocks 202 and 204. Additionally, the diblock copolymer can include repeating units consisting of blocks 202 and 204 such that block 204 follows block 204 and block 204 follows block 202. The block 202 can comprise a different polymer than the block 204, and as such, the characteristics of the block 202 can be different than the characteristics of the block 204.

圖3包括一示例性三嵌段共聚物300的圖示。該三嵌段共聚物300可以包括嵌段302、304、以及306。另外，該三嵌段共聚物可以包括由嵌段302、304、以及306組成的重複單元，使得在嵌段306之後是另一嵌段302。嵌段304可以包括一與嵌段302並且與嵌段306不同的聚合物。另外，嵌段302可以包括一與嵌段306不同的聚合物，使得嵌段302、304、和306的每一個包括一與其他嵌段不同的聚合物。在一替代實施方式中，嵌段302和306可以包括一基本上類似的聚合物。FIG. 3 includes an illustration of an exemplary triblock copolymer 300. The triblock copolymer 300 can include blocks 302, 304, and 306. Additionally, the triblock copolymer can include repeating units consisting of blocks 302, 304, and 306 such that after block 306 is another block 302. Block 304 can include a polymer that is different from block 302 and from block 306. Additionally, block 302 can comprise a different polymer than block 306 such that each of blocks 302, 304, and 306 comprises a different polymer than the other blocks. In an alternate embodiment, blocks 302 and 306 can comprise a substantially similar polymer.

另外，該兩親性嵌段共聚物可以包括一粘合劑易混合的嵌段以及一粘合劑不互混的嵌段。該粘合劑易混合的嵌段可以是一可溶於樹脂中的聚合物嵌段，這樣使得該易混合的嵌段和該樹脂形成該基體的一單相。相反，粘合劑不互混的嵌段可以基本上不溶於樹脂中並且可以在該基體內形成一分離的相。在一實例中，聚苯乙烯嵌段係易混合到酚醛樹脂中的，但是在環氧樹脂中是不互混的。相反，聚(甲基丙烯酸甲酯)嵌段在酚醛樹脂在是不互混的但在環氧樹脂中是易混合的。這樣，由一聚苯乙烯嵌段和一聚(甲基丙烯酸甲酯)嵌段組成的共聚物可以是針對酚醛樹脂和環氧樹脂兩者的一種兩親性嵌段共聚物。Additionally, the amphiphilic block copolymer can include a binder-mixable block and a binder that is not miscible. The binder miscible block can be a polymer block that is soluble in the resin such that the miscible block and the resin form a single phase of the matrix. Conversely, the blocks that are not miscible with the binder can be substantially insoluble in the resin and can form a separate phase within the matrix. In one example, the polystyrene blocks are readily incorporated into the phenolic resin but are not miscible in the epoxy resin. In contrast, poly(methyl methacrylate) blocks are not miscible in phenolic resins but are readily miscible in epoxy resins. Thus, a copolymer composed of a polystyrene block and a poly(methyl methacrylate) block may be an amphiphilic block copolymer for both a phenolic resin and an epoxy resin.

該兩親性嵌段共聚物的交替特性可以導致當與樹脂結合時特定奈米結構的自組裝。在圖4的顯微圖像中描繪了該奈米結構的一實例。圖4的顯微圖像係可以用於形成研磨工具例如一研磨輪的基體材料的一部分的一顯微圖像。The alternating nature of the amphiphilic block copolymer can result in self-assembly of specific nanostructures when combined with the resin. An example of this nanostructure is depicted in the micrograph of Figure 4. The microscopic image of Figure 4 can be used to form a microscopic image of a portion of the abrasive material, such as a base material of a grinding wheel.

在一具體方面，該基體材料可以包括一粘合劑402以及該粘合劑中的一嵌段共聚物。該嵌段共聚物可以包括至少一個第一部分以及第二部分，即，該嵌段共聚物可以包括一種二嵌段共聚物、一種三嵌段共聚物、一種四嵌段共聚物、或一些其他多嵌段共聚物。In a specific aspect, the matrix material can include a binder 402 and a block copolymer of the binder. The block copolymer may include at least one first portion and a second portion, that is, the block copolymer may include a diblock copolymer, a triblock copolymer, a tetrablock copolymer, or some other Block copolymer.

如圖4中指示的，該基體材料可以包括分散在該基體材料中的多個增韌域404。該等增韌域的每一個可以包括該嵌段共聚物的第一部分並且能夠作為一第一相存在於該基體材料中。另外，可以將一種磨料顆粒分散在該基體材料中。As indicated in Figure 4, the matrix material can include a plurality of toughening domains 404 dispersed in the matrix material. Each of the toughening domains can include a first portion of the block copolymer and can be present in the matrix material as a first phase. Additionally, an abrasive particle can be dispersed in the matrix material.

在一具體方面，該嵌段共聚物的第二部分和該粘合劑形成了與該等增韌域的相不同的一個單相。而且，由該嵌段共聚物的第二部分和該粘合劑形成的該第二相可以至少部分地包圍包括在該等增韌域中的形成的該第一相。另一方面，該嵌段共聚物的第一部分包括一粘合劑不互混的部分，並且該嵌段共聚物的第二部分包括一粘合劑易混合的部分。該嵌段共聚物的不互混/易混合性質可以導致在該基體材料中形成該第一相和該第二相。另外，該嵌段共聚物的不互混/易混合性質可以導致該等增韌域(toughening domain)結構的不同形態，例如球形域結構、泡狀域結構、圓柱形域結構等。In a specific aspect, the second portion of the block copolymer and the binder form a single phase that is different from the phases of the toughening domains. Moreover, the second phase formed by the second portion of the block copolymer and the binder can at least partially surround the first phase formed in the toughened domains. In another aspect, the first portion of the block copolymer includes a portion of the binder that is not miscible, and the second portion of the block copolymer includes a portion of the binder that is miscible. The non-intermixing/mixing nature of the block copolymer can result in the formation of the first phase and the second phase in the matrix material. In addition, the non-intermixing/mixing properties of the block copolymer may result in different morphology of the toughening domain structures, such as spherical domain structures, bubble domain structures, cylindrical domain structures, and the like.

In particular, the hardness may be as toughening domains by, hardness of less than about 90% binder, wherein H TD lines and toughening hardness H B domain-based equations [H TD / H B] x100 % analysis Adhesive hardness. Moreover, the toughening domain hardness can be less than about 85% of the hardness of the adhesive, less than about 80% of the hardness of the adhesive, less than about 75%, or less than about 70% of the hardness of the adhesive. In another aspect, the toughening domain hardness can be greater than about 60% of the hardness of the adhesive.

In other words, most of the toughening domains can be spaced apart from one another. In particular, at least about 70% of the toughening domains may be spaced apart from one another. Moreover, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, or at least about 99% of the toughening domains can be spaced apart from one another.

在又另一方面，該嵌段共聚物可以包括至少約3000 g/mol的莫耳質量。具體地說，該莫耳質量可以是至少約3100 g/mol、至少約3200 g/mol、至少約3300 g/mol、至少約3400 g/mol、或至少約3500 g/mol。另一方面，該莫耳質量可以是至少約10000 g/mol、至少約15000 g/mol、至少約20000 g/mol、至少約25000 g/mol、至少約30000 g/mol、至少約35000 g/mol、至少約40000 g/mol、至少約45000 g/mol、或至少約50000 g/mol。In yet another aspect, the block copolymer can comprise a molar mass of at least about 3000 g/mol. Specifically, the molar mass can be at least about 3100 g/mol, at least about 3200 g/mol, at least about 3300 g/mol, at least about 3400 g/mol, or at least about 3500 g/mol.

在使用結合了該等增韌域到其中的研磨輪的過程中，該等增韌域可以作為減震器起作用。換言之，在使用結合了該等增韌域在其中的研磨輪的過程中，該等增韌域可以吸收能量。減振或能量吸收可以歸因於該等增韌域與粘合劑之間硬度上的差異。The toughening domains can function as shock absorbers during use of the grinding wheel incorporating the toughening domains therein. In other words, the toughening domains can absorb energy during use of the grinding wheel incorporating the toughening domains therein. Damping or energy absorption can be attributed to the difference in hardness between the toughening domains and the binder.

轉到製造該粘結的研磨工具的方法，一粘合劑粉末、一兩親性嵌段共聚物粉末、以及一種磨料顆粒形成了一共混的粉末。該粘合劑粉末可以包括一固體酚醛樹脂或一固體環氧樹脂。該兩親性嵌段共聚物粉末可以包括一固體兩親性嵌段共聚物。該固體兩親性嵌段共聚物可以包括一粘合劑易混合的嵌段以及一粘合劑不互混的嵌段。在一實施方式中，該共混的粉末可以包括從約15 wt%至約50 wt%的粘合劑，從約1 wt%至約15 wt%的兩親性嵌段共聚物，以及從約50 wt%至約80 wt%的磨料顆粒。Turning to the method of making the bonded abrasive tool, a binder powder, an amphiphilic block copolymer powder, and an abrasive particle form a blended powder. The binder powder may comprise a solid phenolic resin or a solid epoxy resin. The amphiphilic block copolymer powder may comprise a solid amphiphilic block copolymer. The solid amphiphilic block copolymer may comprise a binder miscible block and a binder which is immiscible. In one embodiment, the blended powder may comprise from about 15 wt% to about 50 wt% binder, from about 1 wt% to about 15 wt% amphiphilic block copolymer, and from about 50 wt% to about 80 wt% of abrasive particles.

該共混的粉末可以成形為一粘結的磨料的形式。在一實施方式中，可以用該共混的粉末來填充一模具空腔，並且可以在該模具內壓縮該共混的粉末。例如，可以藉由冷壓來壓縮該共混的粉末，或可以在壓製的過程中將熱量添加到該粉末上，例如藉由熱壓。The blended powder can be formed into the form of a bonded abrasive. In one embodiment, the blended powder can be used to fill a mold cavity and the blended powder can be compressed within the mold. For example, the blended powder may be compressed by cold pressing, or heat may be added to the powder during pressing, such as by hot pressing.

在成形之後，可以將該基體材料成形的粉末固化從而形成一研磨工具。例如，可以藉由將該共混的粉末加熱到一固化溫度，例如至少約200℃，來將該基體材料固化。在一實施方式中，在保持在該模具空腔內時，可以將該基體材料基本上固化。在另一實施方式中，可以將該基體材料部分地固化到足以維持該研磨工具的形狀的一個點(當從該空腔中移出時)。該研磨工具可以經受另外的固化以在從該模具空腔中移出之後基本上固化該基體材料。After forming, the matrix shaped powder can be cured to form an abrasive tool. For example, the matrix material can be cured by heating the blended powder to a curing temperature, such as at least about 200 °C. In an embodiment, the matrix material can be substantially cured while remaining within the mold cavity. In another embodiment, the base material can be partially cured to a point (when removed from the cavity) sufficient to maintain the shape of the abrasive tool. The abrasive tool can be subjected to additional curing to substantially cure the matrix material after removal from the mold cavity.

在此所述的研磨工具可以具有使該研磨工具適合於改進的研磨和/或切削應用的某些特徵。值得注意地，該粘結的研磨工具的斷裂韌性得以改進。例如，可以藉由測量引起該研磨工具中形成開裂所需要的力(指定為G1 C)，或藉由測量特定的除去力(specific work off force)(SpWOF)(它相應於將一部件折斷離開該粘結的研磨工具所需要的力)來確定斷裂韌性。與常規的磨料物品相比較，在此的實施方式的磨料物品證明了改進的百分比增加的G1 C以及百分比增加的SpWOF。值得注意地，為了比較的目的，該等常規的磨料物品包括相同設計的磨料，具有包括樹脂而不添加兩親性嵌段共聚物的基體材料。根據經驗性證據，該研磨工具可以具有超過不含有兩親性嵌段共聚物的類似研磨工具至少約20%的百分比增加的G1 C。該百分比增加係基於公式((GN -GC )/GC x 100%)，其中GN 表示包括該兩親性嵌段共聚物的研磨工具的G1 C，並且GC 表示不含該兩親性嵌段共聚物的研磨工具的G1 C。在其他實施方式中，該百分比增加G1 C可以是至少約30%，例如至少約40%，例如至少約50%，甚至至少約60%。在一實施方式中，該百分比增加G1 C可以是不大於約500%。The abrasive tool described herein can have certain features that make the abrasive tool suitable for improved grinding and/or cutting applications. Notably, the fracture toughness of the bonded abrasive tool is improved. For example, by measuring the force required to cause cracking in the abrasive tool (designated as G 1 C), or by measuring a specific work off force (SpWOF) (which corresponds to breaking a part) The force required to leave the bonded abrasive tool is determined to determine the fracture toughness. The abrasive article of the embodiments herein demonstrates an improved percentage increase in G 1 C and a percentage increase in SpWOF compared to conventional abrasive articles. Notably, for comparison purposes, such conventional abrasive articles include abrasives of the same design having a matrix material comprising a resin without the addition of an amphiphilic block copolymer. According to empirical evidence, the abrasive tool can have a G 1 C increase of at least about 20% over a similar abrasive tool that does not contain the amphiphilic block copolymer. The percentage increase is based on the formula ((G N - G C ) / G C x 100%), where G N represents the G 1 C of the abrasive tool comprising the amphiphilic block copolymer, and G C represents the absence of the G 1 C of the abrasive tool of the amphiphilic block copolymer. In other embodiments, the percent increase G 1 C can be at least about 30%, such as at least about 40%, such as at least about 50%, even at least about 60%. In an embodiment, the percentage increase G 1 C may be no greater than about 500%.

另外地，經驗性證據還證明該研磨工具可以具有超過不含有兩親性嵌段共聚物的類似研磨工具至少約10%的百分比增加的SpWOF。另外，百分比增加SpWOF可以是至少約15%，例如至少約20%。該百分比增加係基於公式((SN -SC )/SC x 100%)，其中SN 表示具有該兩親性嵌段共聚物的研磨工具的SpWOF，並且SC 表示不含該兩親性嵌段共聚物的研磨工具的SpWOF。在其他實施方式中，該百分比增加SpWOF可以是不大於約500%。Additionally, empirical evidence also demonstrates that the abrasive tool can have a SpWOF that increases by at least about 10% over a similar abrasive tool that does not contain the amphiphilic block copolymer. Additionally, the percentage increase in SpWOF can be at least about 15%, such as at least about 20%. The percentage increase is based on the formula ((S N -S C )/S C x 100%), where S N represents the SpWOF of the abrasive tool having the amphiphilic block copolymer, and S C represents the absence of the parent SpWOF of an abrasive tool for a block copolymer. In other embodiments, the percentage increase SpWOF can be no greater than about 500%.

液體兩親性嵌段共聚物，例如在美國公開物2009/0082486 A1中所述的，被用於對用於多種應用中(例如層壓)的環氧樹脂進行增韌。該等應用依賴於包括聚(氧化乙烯)(PEO)和聚(氧化丁烯)(PBO)的一種兩親性嵌段共聚物。然而，使用液體樹脂體系會引起產生粘結的磨料物品的問題，例如該等磨料顆粒在該液體中部分沉降。這可能導致磨料顆粒的不均勻分佈以及不均勻的研磨性能。使用固體兩親性嵌段共聚物粉末為形成粘結的磨料物品提供了特別的優點。Liquid amphiphilic block copolymers, such as those described in U.S. Publication No. 2009/0082486 A1, are used to toughen epoxy resins for use in a variety of applications, such as lamination. Such applications rely on an amphiphilic block copolymer comprising poly(ethylene oxide) (PEO) and poly(butylene oxide) (PBO). However, the use of liquid resin systems can cause problems with bonded abrasive articles, such as the partial deposition of such abrasive particles in the liquid. This can result in uneven distribution of abrasive particles as well as uneven grinding performance. The use of solid amphiphilic block copolymer powders provides particular advantages for forming bonded abrasive articles.

另外，在某些實施方式中，可以用於增加研磨輪應用中所使用的粘合劑的強度或韌性的嵌段共聚物量值可以是這樣一小的量值，當與該粘合劑材料比較時，當將這樣一聚合物的液體形式與一粘合劑粉末混合時，這個量值往往是極其難以得到基本上均勻分散的。然而，將這樣一嵌段共聚物的粉末形式進行混合可以允許在從該嵌段共聚物/粘合劑粉末混合物形成磨料物品之前將該嵌段共聚物均勻分散到該粘合劑粉末中。Additionally, in certain embodiments, the amount of block copolymer that can be used to increase the strength or toughness of the adhesive used in the application of the abrasive wheel can be such a small amount as when the adhesive material is In comparison, when a liquid form of such a polymer is mixed with a binder powder, this amount tends to be extremely difficult to obtain substantially uniformly dispersed. However, mixing the powder form of such a block copolymer may allow the block copolymer to be uniformly dispersed into the binder powder before forming the abrasive article from the block copolymer/binder powder mixture.

形成了數種類型的磨料物品並且進行測試以將某些性能參數(包括臨界能釋放率(G1C)以及特定的除去力(SpWOF))進行比較。G1C係引起測試磨料物品開裂所需要的力的一測量值，並且SpWOF係引起該測試磨料物品的一部分折斷所需要的力一測量值。Several types of abrasive articles were formed and tested to compare certain performance parameters, including critical energy release rate (G1C) and specific removal force (SpWOF). G1C is a measure of the force required to test the cracking of the abrasive article, and the SpWOF system is a measure of the force required to break a portion of the test abrasive article.

The phenolic resin and the amphiphilic block copolymer were blended in a ratio of 90 wt% resin to 10 wt% copolymer to form a substantially uniform powder blend. The powder blend was pressed into a mold and heated to a temperature of 200 ° C for 1 hour. The results of the G 1 C and SpWOF tests are shown in Table 2.

對比實例3係藉由將一酚醛樹脂粉末壓製到一模具中並且將它加熱到200℃的溫度持續1小時而製備的一基於酚醛樹脂的配製品。Comparative Example 3 is a phenolic resin-based formulation prepared by pressing a phenolic resin powder into a mold and heating it to a temperature of 200 ° C for 1 hour.

如對比實例2藉由添加一種兩親性嵌段共聚物粉末製備了樣品3。將該酚醛樹脂和該兩親性嵌段共聚物以90 wt%樹脂對10 wt%共聚物的比率進行共混從而形成一基本上均勻的粉末共混物。將該粉末共混物壓製到一模具中並且加熱到200℃的溫度持續1小時。在表3顯示了G1 C和SpWOF測試的結果。Sample 3 was prepared as in Comparative Example 2 by adding an amphiphilic block copolymer powder. The phenolic resin and the amphiphilic block copolymer were blended in a ratio of 90 wt% resin to 10 wt% copolymer to form a substantially uniform powder blend. The powder blend was pressed into a mold and heated to a temperature of 200 ° C for 1 hour. The results of the G 1 C and SpWOF tests are shown in Table 3.

如藉由表1至2中提供的數據可見，將特定的兩親性嵌段共聚物添加到粘結的磨料物品的樹脂中可以改進該等粘結的磨料物品的韌性。具體地說，使該基體材料開裂所需要的力和使該基體材料斷裂所需要的力兩者比無該兩親性嵌段共聚物的配製品都有所增加。As can be seen from the data provided in Tables 1 through 2, the addition of a particular amphiphilic block copolymer to the resin of the bonded abrasive article can improve the toughness of the bonded abrasive article. Specifically, both the force required to crack the matrix material and the force required to break the matrix material are increased compared to the formulation without the amphiphilic block copolymer.

在另一實例中，使用下面表4中詳述的配方製備了一標準的磨料物品。表5列出了表4中提及的標準粘結劑的成分。還使用與表4中詳細說明的相同配方製備了一嵌段共聚物(BCP)磨料物品。然而，該BCP磨料物品包括如在此所述將一嵌段共聚物添加到該標準粘結劑材料中。該嵌段共聚物包括一粘合劑易混合的嵌段以及一粘合劑不互混的嵌段。另外，該嵌段共聚物包括一PMMA嵌段共聚物。In another example, a standard abrasive article was prepared using the formulation detailed in Table 4 below. Table 5 lists the ingredients of the standard binders mentioned in Table 4. A block copolymer (BCP) abrasive article was also prepared using the same formulation as detailed in Table 4. However, the BCP abrasive article comprises a block copolymer added to the standard binder material as described herein. The block copolymer comprises a binder-admixable block and a block in which the binder is not miscible. Additionally, the block copolymer comprises a PMMA block copolymer.

具體地說，將該嵌段共聚物與該標準粘結劑以1:99(嵌段共聚物對標準粘結劑)的比率進行共混。此外，該嵌段共聚物係處於一固態、粉末的形式以有助於徹底混合和基本上均勻分散，如在此說明的。藉由對完成的BCP磨料物品拍攝不同的顯微照片並且確定由該嵌段共聚物的不互混部分而形成的增韌域的相關分散性來確定分散性。Specifically, the block copolymer is blended with the standard binder at a ratio of 1:99 (block copolymer to standard binder). In addition, the block copolymer is in a solid, powder form to aid in thorough mixing and substantially uniform dispersion, as described herein. Dispersibility is determined by taking different photomicrographs of the finished BCP abrasive article and determining the relative dispersibility of the toughening domains formed by the immiscible portions of the block copolymer.

一旦將用於各個輪的混合物進行共混，就將該粉末共混物壓製到一模具中並且加熱到200℃的溫度持續1小時。在製造該等磨料物品之後，將每個磨料物品放在一破裂測試裝置中。將每個磨料物品自由地自旋或旋轉直至每個輪發生災難性失效，即直到它破裂。將該磨料物品發生失效的速度記錄下來作為破裂速度。Once the mixture for each wheel was blended, the powder blend was pressed into a mold and heated to a temperature of 200 ° C for 1 hour. After manufacturing the abrasive articles, each abrasive article is placed in a rupture test device. Each abrasive article is free to spin or rotate until each wheel experiences a catastrophic failure, i.e., until it ruptures. The rate at which the abrasive article failed was recorded as the rate of rupture.

圖5顯示了破裂測試的結果，為一簡單的柱狀圖。標準磨料物品提供了約6800 RPM的破裂速度。用嵌段共聚物構建的BCP磨料物品(如在此說明的)提供了約7100 RPM的破裂速度。因此，用該嵌段共聚物構建的BCP磨料物品提供了一破裂速度，該破裂速度比藉由式：[BSBCP -BSST ]/BSST x 100%給出的標準磨料物品的破裂速度高出約4.4%，其中BSBCP 係BCP磨料物品的破裂速度並且BSST 係標準磨料物品的破裂速度。Figure 5 shows the results of the rupture test as a simple histogram. Standard abrasive articles provide a burst speed of approximately 6800 RPM. A BCP abrasive article constructed as a block copolymer (as described herein) provides a burst speed of about 7100 RPM. Therefore, the BCP abrasive article constructed with the block copolymer provides a rupture speed which is higher than the rupture speed of a standard abrasive article given by the formula: [BS BCP -BS ST ] / BS ST x 100% Approximately 4.4%, where BS BCP is the rupture speed of the BCP abrasive article and the BS ST is the rupture speed of the standard abrasive article.
