本発明は、メタルボンドよりなる貼付型研削シ
ートに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adhesive type grinding sheet made of metal bond.
レンズの研削工程において、ダイヤモンドペレ
ツトを使用する研削が、砂を大量に使用する従来
の砂掛けに代わり最近広く行われつつある。これ
は所定のカーブの皿に、接着剤で貼り付けられた
同じカーブを持つダイヤモンドペレツトにより行
われる。 In the lens grinding process, grinding using diamond pellets has recently become widely used in place of the conventional sanding method that uses a large amount of sand. This is done by means of a diamond pellet of the same curve, which is glued to a plate of a given curve.
ダイヤモンドペレツトによる研削が採用される
理由は、研削能率及び歩留の向上、作業環境の改
良及び廃棄物処理の容易など多くの利点が得られ

のレンズを大量に研削加工する場合には、ダイヤ
モンドペレツトの方がコスト的にも圧倒的に有利
である。 The reason why diamond pellet grinding is adopted is that it offers many advantages such as improved grinding efficiency and yield, improved working environment, and easier waste disposal, especially for lenses of the same glass type with the same curve. When grinding a large amount of diamond, diamond pellets are overwhelmingly advantageous in terms of cost.
しかしながら、乱視用レンズの場合、カーブの

尽くすまで長期間かかる。このような特殊用途に
ダイヤモンドペレツトを採用することはプライム
コストが高いので採用を見合わせる場合が多い。 However, in the case of lenses for astigmatism, there are many types of curves, so pellets with the same curve are used less frequently.In addition, in the case of small lot products such as interchangeable lenses for cameras, pellets with the same curve are used less often and the In this case, it will take a long time to use it all up. The use of diamond pellets for such special purposes is often postponed due to the high prime cost.

用化されない場合が多い。 In addition to the above-mentioned applications, when a complex-shaped or special-sized diamond tool is required, since truing of metal bonded grinding wheels is generally difficult, the tool becomes extremely expensive and is often not put to practical use as a tool. .

着剤で貼り付けたものである。 In order to solve the above-mentioned problems, it has been desired to develop a diamond tool that has a low prime cost even at the cost of its life, and various thin adhesive-type grinding sheets have been sold or devised. These are highly flexible and are used by being attached to a plate or base metal having a predetermined curve or shape. One type of grinding sheet is one in which abrasive grains such as diamond are fixed to a base sheet made of copper foil or vapor-deposited metal along with electrodeposited nickel bond.Other types are low melting point sheets that hold abrasive grains such as diamond. A metal bond is mechanically fixed to a base synthetic resin sheet or cloth or attached with an adhesive.

どの欠点を持ち実用には不十分である。 However, with the above-mentioned grinding sheets, the metal bond easily peels off from the base, the types of metal bonds that can be used are severely limited, and excellent metal bonds cannot be used, so the required cutting performance cannot be satisfied or surface accuracy cannot be maintained. It has disadvantages such as being difficult and is not suitable for practical use.

A release paper 4 and a release paper 4 are provided on the back side of the wire mesh 2. During use, the user often peels off the release paper 4 and presses the adhesive-applied surface onto a tool body such as a plate or base metal. Here, the adhesive layer is not only the adhesive, but also the adhesive layer as a whole, such as a double-sided tape with adhesive applied to both sides of a sheet of cloth, paper, rubber, etc. called backing. Also includes things. The base portion of the metal bond sintered body 1 and the wire mesh 2 are bonded in some cases, as shown in FIG. 2, in a part of the thickness of the wire mesh 2, and in other cases, as shown in FIG. However, even if it is done in a portion as shown in Fig. 2, it is sufficient for practical strength. 4 and 5 show the planar shape of the metal bond 1, in which a large number of voids 5 are formed.

Examples of copper-based metal bonds that are useful include pure copper, copper-tin, copper-tin-silver, copper-tin-nickel, and copper-tin-iron. Examples of nickel-based metal bonds that are useful include pure nickel, nickel-tin, nickel-phosphorus, nickel-zinc, and nickel-copper-tin-phosphorus. As mentioned above, there are a wide variety of metal bonds that require sintering, and if an appropriate bond is selected depending on the application, abrasive grains can be used effectively to provide excellent cutting performance.

A blade that spreads over the entire base is not preferable in terms of sharpness and is limited to applications where the roughness of the machined surface is important. On the other hand, the metal bond sintered body 1 illustrated in FIG. 1 is distributed in multiple islands, and the metal bond sintered body 1 illustrated in FIGS. 4 and 5 is an integral structure. However, a shape in which the voids 5 are distributed in a plurality of islands is particularly preferable in terms of supply of coolant to the machined surface and discharge of chips.
