Description

本発明は、研削工具を製造するために用いられる砥粒を適切に配列する方法と、この方法によって配列された砥粒を用いて製造される研削工具に関する。   The present invention relates to a method for properly arranging abrasive grains used for manufacturing a grinding tool, and a grinding tool manufactured using abrasive grains arranged by this method.

ダイヤモンド、ＣＢＮ、ＴｉＣ等の砥粒を金属結合材で結合して製造された研削工具がよく用いられているが、これらの砥粒はそのままでは接着性が良くないために、これらの砥粒に対して金属で被覆することがよく行われている。このようにして金属被覆が施された砥粒を用いた研削工具として、例えばコンクリート切断用ブレード、レジンホイール等がある。また、これらの研削工具に関する先行技術文献として、以下のものがある。   Grinding tools manufactured by bonding abrasive grains such as diamond, CBN, and TiC with a metal binder are often used. However, since these abrasive grains have poor adhesion as they are, On the other hand, it is often performed to coat with metal. Examples of the grinding tool using the abrasive grains thus coated with metal include a concrete cutting blade and a resin wheel. Further, as prior art documents related to these grinding tools, there are the following.

特開平１０−２６４０３４号公報Japanese Patent Laid-Open No. 10-264034 特開平４−２５０９８１号公報Japanese Patent Laid-Open No. 4-250981

金属被覆を行うと砥粒の接着性は向上する一方で、砥粒の全面が金属被覆で覆われるため、研削面として機能する面も金属被覆で覆われることとなり、砥粒の研削能力を有効に引き出すことができない。また、砥粒の研削面に金属被覆が存在することによって、被研削材に金属被覆が接触することとなり、被研削材へ悪影響を及ぼす場合がある。
本発明は、このような問題点を解決するためになされたもので、金属被覆を施して結合材との接着力を高めつつ、砥粒の研削面の研削性能を低下させることのない砥粒配列方法と、この砥粒配列方法を利用して製造された研削工具を提供することを目的とする。 When metal coating is applied, the adhesiveness of the abrasive grains is improved. On the other hand, the entire surface of the abrasive grains is covered with the metal coating, so that the surface that functions as the grinding surface is also covered with the metal coating. Can not be pulled out. In addition, the presence of the metal coating on the grinding surface of the abrasive grains causes the metal coating to come into contact with the material to be ground, which may adversely affect the material to be ground.
The present invention has been made in order to solve such problems, and the abrasive grains that do not deteriorate the grinding performance of the abrasive surface of the abrasive grains while applying a metal coating to increase the adhesive force with the binder. It aims at providing the grinding | polishing tool manufactured using the arrangement | sequence method and this abrasive grain arrangement | sequence method.

以上の課題を解決するために、本発明は、磁性を有する金属を用いて砥粒の所定の方向の面に被覆を形成し、この砥粒を磁界によって前記被覆が形成された面が台金の方向を向くように整列し、少なくとも前記被覆が金属結合材と接触するようにして砥粒を固定することを特徴とする砥粒配列方法である。   In order to solve the above problems, the present invention forms a coating on a surface in a predetermined direction of abrasive grains using a metal having magnetism, and the surface on which the coating is formed by a magnetic field is a base metal. A method for arranging abrasive grains, wherein the abrasive grains are fixed so that the coatings are in contact with each other and at least the coating is in contact with the metal binder.

砥粒の表面のうち、金属被覆が施された面は金属結合材と接触するため金属被覆によって結合が強固となる。その一方、砥粒の表面のうち、金属被覆が施されていない面が金属結合材から突出して研削面となるため、研削時に金属被覆によって砥粒の研削性能が低下することがない。   Of the surfaces of the abrasive grains, the surface coated with the metal is in contact with the metal binder, so that the bond is strengthened by the metal coating. On the other hand, among the surfaces of the abrasive grains, the surface that is not coated with metal protrudes from the metal binder and becomes a ground surface, so that the grinding performance of the abrasive grains is not reduced by the metal coating during grinding.

本発明は、前述の砥粒配列方法を用いて砥粒を単層に配列した研削工具であって、砥粒表面のうち、被覆が形成された面が金属結合材と接触して砥粒が台金に固定され、被覆が形成されていない面が研削面となるように形成されたことを特徴とする研削工具である。   The present invention is a grinding tool in which abrasive grains are arranged in a single layer by using the above-described abrasive grain arranging method, and the surface of the abrasive grain surface on which the coating is formed comes into contact with the metal binder and the abrasive grains are A grinding tool characterized in that a surface fixed to a base metal and having no coating formed thereon is a ground surface.

金属被覆が施された面は金属結合材と接触するため金属被覆によって結合が強固となる。その一方、砥粒の表面のうち、金属被覆が施されていない面が金属結合材から突出して研削面となるため、研削時に金属被覆によって砥粒の研削性能が低下することがなく、研削性能に優れた研削工具を実現することができる。また、金属被覆が施されていない面が被研削材と接触するため、被研削材が金属被覆によって汚染されることがない。そのため、半導体部品のように微量な金属元素が混入することをも防止することが要求される精密部品の加工に好適である。   Since the surface on which the metal coating is applied comes into contact with the metal bonding material, the bonding is strengthened by the metal coating. On the other hand, the surface of the abrasive grain that is not coated with metal protrudes from the metal binding material to become a ground surface, so that the grinding performance of the abrasive grains is not reduced by the metal coating during grinding. It is possible to realize an excellent grinding tool. Further, since the surface not coated with metal is in contact with the material to be ground, the material to be ground is not contaminated by the metal coating. Therefore, it is suitable for the processing of precision parts that are required to prevent a trace amount of metal elements from being mixed, such as semiconductor parts.

本発明は、前述の砥粒配列方法を用いて砥粒を多層に配列した研削工具であって、砥粒表面のうち、被覆が形成された面が台金の方向を向くように整列してボンド材で固定されて形成されたことを特徴とする研削工具である。
金属被覆が施されていない上側表面ではボンド材との接着力が弱いために、砥粒の目替わりが進行しやすい。その一方、金属被覆が施されている下側表面ではボンド材との接着力が強いために、砥粒保持力が強い。このように、一つの砥粒において目替わりの進行と砥粒保持力を同時に満たすことができ、切れ味に優れ、寿命の向上が可能な研削工具を実現することができる。 The present invention is a grinding tool in which abrasive grains are arranged in multiple layers using the above-described abrasive grain arranging method, and the abrasive grains are aligned so that the surface on which the coating is formed faces the direction of the base metal. It is a grinding tool characterized by being formed by being fixed with a bond material.
Since the adhesive force with the bond material is weak on the upper surface where the metal coating is not applied, the change of abrasive grains tends to proceed. On the other hand, since the adhesive force with the bond material is strong on the lower surface on which the metal coating is applied, the abrasive grain holding power is strong. In this way, it is possible to realize a grinding tool that can simultaneously satisfy the progress of changeover and the holding power of abrasive grains in one abrasive grain, and that has excellent sharpness and can improve the service life.

本発明は、前記被覆が形成された面の表面積が前記砥粒の表面積の３０％以上７０％以下であることを特徴とする。
被覆が形成された面の表面積が砥粒の表面積の３０％未満であると、磁力により砥粒を反転させて配列する際に、被覆された面の表面積が小さいために磁力による制御を充分に行うことができない。一方、被覆が形成された面の表面積が砥粒の表面積の７０％を超えると、研削面にも被覆が形成されるようになり、研削性能が低下する。 The present invention is characterized in that the surface area of the surface on which the coating is formed is 30% or more and 70% or less of the surface area of the abrasive grains.
If the surface area of the surface on which the coating is formed is less than 30% of the surface area of the abrasive grains, the surface area of the coated surface is small when the abrasive grains are reversed and arranged by magnetic force. I can't do it. On the other hand, when the surface area of the surface on which the coating is formed exceeds 70% of the surface area of the abrasive grains, the coating is also formed on the ground surface, and the grinding performance is degraded.

本発明によると、磁性を有する金属を用いて砥粒の所定の方向の面に被覆を形成し、この砥粒を磁界によって前記被覆が形成された面が台金の方向を向くように整列し、少なくとも前記被覆が金属結合材と接触するようにして砥粒を固定することにより、砥粒の結合を強固なものとしつつ、砥粒の研削性能を良好に維持することができる。   According to the present invention, a coating is formed on a surface of an abrasive grain in a predetermined direction using a magnetic metal, and the abrasive grain is aligned by a magnetic field so that the surface on which the coating is formed faces a base metal. By fixing the abrasive grains so that at least the coating comes into contact with the metal binder, it is possible to maintain the grinding performance of the abrasive grains satisfactorily while strengthening the bonding of the abrasive grains.

本発明によると、上記の砥粒の配列方法を用いて砥粒を単層に配列して研削工具を作製することにより、砥粒の結合が強固で、砥粒の研削性能を良好に維持することができ、被研削材が金属被覆によって汚染されることがない研削工具を実現することができる。   According to the present invention, the abrasive grains are arranged in a single layer using the above-described abrasive grain arrangement method to produce a grinding tool, whereby the abrasive grains are firmly bonded and the abrasive grinding performance is maintained well. It is possible to realize a grinding tool in which the material to be ground is not contaminated by the metal coating.

本発明によると、上記の砥粒の配列方法を用いて砥粒を多層に配列して研削工具を作製することにより、目替わりの進行と砥粒保持力を同時に満たすことができ、切れ味に優れ、寿命の向上が可能な研削工具を実現することができる。   According to the present invention, by using the above-described method for arranging abrasive grains to produce a grinding tool by arranging abrasive grains in multiple layers, the progress of change and the abrasive holding power can be satisfied at the same time, and the sharpness is excellent. Thus, a grinding tool capable of improving the life can be realized.

以下、本発明の砥粒配列方法をその実施形態に基づいて説明する。
図１に、本発明の実施形態に係る砥粒配列方法を示す。図１（ａ）に示す砥粒１に対して、（ｂ）のように、その上側半面に金属被覆２がなされるように金属材料を蒸着する。金属被覆２を施す方法は蒸着に限定されるものではないが、少なくとも砥粒１に対して一方向から金属被覆２を形成できる方法を選択する。例えば、スパッタリングやクラスターイオンビーム蒸着などによっても金属被覆２を形成できる。この被覆に用いられる金属材料は磁性を有するものを用いる。 Hereinafter, an abrasive grain arranging method of the present invention is explained based on the embodiment.
FIG. 1 shows an abrasive grain arranging method according to an embodiment of the present invention. A metal material is vapor-deposited on the abrasive grains 1 shown in FIG. 1 (a) so that the metal coating 2 is formed on the upper half surface thereof as shown in FIG. 1 (b). The method of applying the metal coating 2 is not limited to vapor deposition, but a method that can form the metal coating 2 from at least one direction with respect to the abrasive grains 1 is selected. For example, the metal coating 2 can be formed by sputtering or cluster ion beam evaporation. The metal material used for the coating is a magnetic material.

このようにして金属被覆２が施された砥粒１に対して磁界をかけ、（ｃ）に示すように、台金３に金属被覆２が接するように砥粒１を配列させる。この状態で（ｄ）に示すように金属結合材４で砥粒１を台金３上で結合する。
このようにして砥粒１を配列すると、砥粒１の表面のうち、金属被覆２が施された面は金属結合材４と接触するため金属被覆２によって結合が強固となる。一方、砥粒１の表面のうち、金属被覆２が施されていない面が金属結合材４から突出して研削面となるため、研削時に金属被覆２によって砥粒１の研削性能が低下することがない。
以上の砥粒配列方法を用いて製造される研削工具における砥粒の配列状況の例を図２、図３に示す。 A magnetic field is applied to the abrasive grains 1 coated with the metal coating 2 in this way, and the abrasive grains 1 are arranged so that the metal coating 2 is in contact with the base metal 3 as shown in FIG. In this state, the abrasive grains 1 are bonded on the base metal 3 with the metal bonding material 4 as shown in FIG.
When the abrasive grains 1 are arranged in this way, the surface of the abrasive grains 1 on which the metal coating 2 is applied comes into contact with the metal binding material 4, so that the bonding is strengthened by the metal coating 2. On the other hand, the surface of the abrasive grain 1 on which the metal coating 2 is not applied protrudes from the metal binder 4 to become a grinding surface, and therefore the grinding performance of the abrasive grain 1 may be reduced by the metal coating 2 during grinding. Absent.
Examples of the state of arrangement of abrasive grains in a grinding tool manufactured using the above-described abrasive grain arrangement method are shown in FIGS.

図２は、電着等によって砥粒１を台金３に単層に固着して形成される研削工具の場合を示しており、砥粒１の表面のうち、金属結合材４と接触する側には金属被覆２が施されており、上側の研削面となる側には金属被覆２が施されていない。この研削工具を用いると、金属被覆２が施されていない面が被研削材と接触するため、被研削材が金属被覆２によって汚染されることがない。そのため、半導体部品のように微量な金属元素が混入することをも防止することが要求される精密部品の加工に好適である。   FIG. 2 shows the case of a grinding tool formed by adhering abrasive grains 1 to a base metal 3 by electrodeposition or the like, and the side of the abrasive grains 1 in contact with the metal binder 4 Is provided with a metal coating 2, and the metal coating 2 is not applied to the side which becomes the upper grinding surface. When this grinding tool is used, the surface to which the metal coating 2 is not applied comes into contact with the material to be ground, so that the material to be ground is not contaminated by the metal coating 2. Therefore, it is suitable for the processing of precision parts that are required to prevent a trace amount of metal elements from being mixed, such as semiconductor parts.

図３は、砥粒１をレジンボンド等のボンド材５を用いて多層に結合して砥粒層を形成した研削工具の場合を示しており、砥粒１の表面のうち、下側には金属被覆２が施されており、研削面となる上側には金属被覆２が施されていない。従って、砥粒１の下側はボンド材５との接着力が強く、砥粒１の上側はボンド材５との接着力が弱い。   FIG. 3 shows a case of a grinding tool in which abrasive grains 1 are bonded in multiple layers using a bonding material 5 such as a resin bond to form an abrasive grain layer. The metal coating 2 is applied, and the metal coating 2 is not applied on the upper side which is the grinding surface. Accordingly, the lower side of the abrasive grain 1 has a strong adhesive force with the bond material 5, and the upper side of the abrasive grain 1 has a weak adhesive force with the bond material 5.

この砥粒層は研削が進行するに従って摩耗するが、砥粒１のうち、金属被覆２が施されていない上側表面ではボンド材５との接着力が弱いために、砥粒１の目替わりが進行しやすい。その一方、金属被覆２が施されている下側表面ではボンド材５との接着力が強いために、砥粒保持力が強い。このように、一つの砥粒において目替わりの進行と砥粒保持力を同時に満たすことができ、切れ味に優れ、寿命の向上が可能である。   The abrasive layer wears as the grinding progresses. However, since the adhesive force with the bond material 5 is weak on the upper surface of the abrasive grain 1 where the metal coating 2 is not applied, the change of the abrasive grain 1 is changed. Easy to progress. On the other hand, since the adhesive force with the bond material 5 is strong on the lower surface on which the metal coating 2 is applied, the abrasive grain holding power is strong. Thus, the progress of change and the abrasive holding power can be satisfied at the same time in one abrasive grain, and it is excellent in sharpness and the life can be improved.

以下に、本発明の砥粒の具体的な配列方法と、この配列方法によって作製された研削工具の試験結果について説明する。
コバルトがコートされたＣＢＮ砥粒に対して、砥粒の高さの約半分が浸るように硝酸を注いでコバルトコートを溶解して得られた砥粒１を、磁力によって図１（ｃ）のように反転させて図１（ｄ）のように金属結合材４で台金３に固定した。金属結合材４としてＮｉ−Ｃｒ系のろう材を用い、台金３として鉄系のものを用いている。 Hereinafter, a specific method for arranging the abrasive grains of the present invention and a test result of a grinding tool produced by this method will be described.
With respect to the CBN abrasive grains coated with cobalt, the abrasive grains 1 obtained by pouring nitric acid so as to immerse about half the height of the abrasive grains and dissolving the cobalt coat are magnetically converted into those shown in FIG. It was reversed and fixed to the base metal 3 with the metal binder 4 as shown in FIG. A Ni—Cr brazing material is used as the metal bonding material 4, and an iron-based material is used as the base metal 3.

この方法で得られた発明品の性能を検証するために、ろう材と台金は同じものを使用し、コバルトコートを施さずにＣＢＮ砥粒だけを配列して形成された比較品１と、コバルトコートを施したＣＢＮ砥粒に対して磁力による操作を行わずに砥粒を配列して形成された比較品２とを比較対象として研削試験を行った。   In order to verify the performance of the invention product obtained by this method, the same brazing material and base metal are used, and a comparative product 1 formed by arranging only CBN abrasive grains without applying a cobalt coat, A grinding test was conducted on a comparative product 2 formed by arranging abrasive grains on the CBN abrasive grains coated with cobalt without using a magnetic force operation.

図４にその結果を示す。比較品１，比較品２，発明品のいずれにおいても、左側の棒グラフが寿命を示し、右側の棒グラフが切れ味指数を示しており、発明品の切れ味指数と寿命を１００として表現している。比較品２はコバルトコートが施されていることによって比較品１に比べて切れ味が低下しているが、発明品では磁力による操作を行うことによってコートされていない面が研削面となるため、切れ味が低下することがない。また、比較品１では、コバルトコートが施されていないことによって、ろう材との結合力が弱く寿命が極めて短いのに対して、発明品ではろう材との接触面にコバルトコートがあるため、結合力が強く寿命が長い。このように、発明品は、比較品１、比較品２の長所を併せ持つことに大きな利点がある。   FIG. 4 shows the result. In each of the comparative product 1, the comparative product 2 and the invention product, the left bar graph shows the life, the right bar graph shows the sharpness index, and the sharpness index and the life of the invention product are expressed as 100. The comparative product 2 has a sharpness lower than that of the comparative product 1 due to the cobalt coating, but in the inventive product, the surface that is not coated by performing an operation by magnetic force becomes a ground surface. Will not drop. Further, in Comparative Product 1, because the cobalt coating is not applied, the bonding force with the brazing material is weak and the life is extremely short, whereas the invention product has a cobalt coating on the contact surface with the brazing material. Strong binding strength and long life. Thus, the invention product has a great advantage in having the advantages of the comparative product 1 and the comparative product 2 together.

本発明は、砥粒保持力と研削性能に優れた研削工具として利用することができる。   The present invention can be used as a grinding tool excellent in abrasive grain retention and grinding performance.
