【発明の詳細な説明】 [発明の目的] (産業上の利用分野) 本発明は研摩砥石に関する。[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an abrasive wheel.
(従来の技術)
一般に研削加工においては、研摩砥石が工作物と接触し

目つまりなどを少なくするために、研摩部位に冷却液を
注ぐ必要がある。(Prior art) In general, during grinding, the part where the grinding wheel comes into contact with the workpiece and polishes it, that is, the part to be polished, becomes very hot, so this is cooled to prevent deterioration of the polished surface of the workpiece due to heat. In order to improve the surface finish by removing debris and chips from the grinding area, and to reduce wear and clogging of the grinding wheel through lubrication, it is necessary to pour a coolant into the area being polished.

射する手段が採用されている。Conventionally, in order to pour coolant into the part to be polished on a grinding machine such as a surface grinder or cylindrical grinder, a coolant nozzle is placed near the outside of the grinding wheel, and this nozzle is connected to a coolant supply device via a hose. However, a means is employed in which the cooling liquid supplied from the cooling liquid supply device through the hose is radiated from the nozzle toward the polishing site.
(発明が解決しようとする課題)
しかしながら、このように冷却液を研摩砥石の外部から

潤滑して良好な研摩加工を行なうことが困難である。(Problem to be Solved by the Invention) However, with this method of pouring the coolant from the outside of the grinding wheel, when the contact area of the grinding wheel with the workpiece is large, that is, when the area of the polished part is large, It may not be possible to pour the coolant to the entire area to be polished, and depending on the shape of the part to be polished, it may be blocked by the grindstone or the workpiece, making it impossible to pour the cooling liquid to the area to be polished from the outside. In these cases, it is difficult to reliably cool and lubricate the area to be polished with sufficient cooling fluid to perform a good polishing process.
本発明は前記事情に基づいてなされたもので、冷却液を
研摩部位に確実に供給して良好な研摩加工を行なうこと
ができる研摩砥石を提供することを目的とする。The present invention has been made based on the above-mentioned circumstances, and an object of the present invention is to provide a polishing wheel that can reliably supply a cooling liquid to a polishing area and perform a good polishing process.

液を外部に漏らすことなく研摩砥石の内部を通して研摩
部位に確実に供給できることを見出した。The inventor of the present invention has conducted repeated research on pouring a coolant into the polished area during polishing, but the method of pouring the coolant from outside the grinding wheel does not allow for polishing without being restricted by various conditions. It has been discovered that there is a limit to the ability to pour a sufficient amount of cooling liquid to the part to be polished, and that by passing the cooling liquid through the inside of the polishing wheel, it is possible to reliably pour the cooling liquid to the part to be polished. That is, since the polishing whetstone is a porous body formed by bonding abrasive grains with a binder, it is possible to pass a cooling liquid through the many pores present inside the whetstone. However, as a result of further research by the inventor, it was discovered that when coolant is injected into a normal grinding wheel, it leaks from the outer surface of the entire grinding wheel through the pores.
It has been found that the rate at which the coolant passes through the interior of the polishing wheel and reaches the target area to be polished is very low, making it impossible to achieve the original purpose. Therefore, the inventor created a cooling liquid passage inside the grinding wheel by closing the pores on the outer surface of the grinding wheel in unnecessary parts to prevent the cooling liquid from leaking out. It has been found that it is possible to reliably supply the polishing portion through the inside of the polishing wheel.
すなわち、本発明の研摩砥石は、多孔質体で形成され、
外表部の気孔を閉じて内部に流体の通路を形成してなる
ことを特徴とするものである。That is, the polishing wheel of the present invention is formed of a porous material,
It is characterized in that the pores on the outer surface are closed to form a fluid passage inside.
本発明の研摩砥石は円筒研摩、平面研摩および内面研摩
などの冷却液供給装置を備えた各研摩盤に使用する研摩
砥石に広く適用できる。The polishing wheel of the present invention can be widely applied to polishing wheels used in various polishing machines equipped with a cooling liquid supply device for cylindrical polishing, plane polishing, internal polishing, and the like.
本発明の研摩砥石は、これを構成する砥粒、結合剤およ

冷却液を通すのに適した形態であることが望ましい。The abrasive grains, bonding agent, and structure of the polishing wheel of the present invention are not necessarily specified, but it is preferable that the polishing wheel has a form suitable for passing a cooling liquid therein.

容易に通すことができるように大きな気孔が相互に連通
した組織が形成される。This form will be explained. The structure of a whetstone is determined by the relationship between the abrasive grains and the binder; a coarse structure has a few large pores, and a dense structure has many small pores. Therefore, in order to allow the grinding fluid to flow smoothly, a structure having many large pores that communicate with each other is preferable. The porosity of this structure is preferably 30 to 70%. In order to achieve this structure, it is preferable that the grain size of the abrasive grains constituting the polishing wheel be #200 or coarser.If the abrasive grains are finer than this, special treatment or special treatment of the abrasive grains is required. Using a manufacturing method, the volume ratio of abrasive grains to the total volume of the whetstone is set to 40% or less, and a vitrified binder, a silicate binder, or the like is used as a binder for binding the abrasive grains. As a result, the polishing wheel has a structure in which large pores communicate with each other so that the cooling liquid can easily pass therethrough.
本発明の研摩砥石は、内部に液体に通路を形成するため

表部の気孔を閉じる。The pores of the polishing wheel can be closed by applying an adhesive such as epoxy resin, polyester resin, or phenol resin to the surface of the pores, or allowing the adhesive to permeate the surface of the pores. The use of adhesive allows the pores of the grindstone to be easily and reliably closed. There are several methods for applying the adhesive to the surface of the grinding wheel, such as brushing, spraying, and impregnation. The thickness of the adhesive applied is 0.2 to 5 cm. The part on the outer surface of the grinding wheel where the pores are closed, that is, where the adhesive is applied, is located between the part where the coolant is injected into the grinding wheel and the part that comes into contact with the workpiece (the part where the coolant is poured out). This is the entire outer surface of the part that connects. That is, the pores on the outer surface of the grinding wheel are closed to prevent the cooling liquid from leaking to the outside while the cooling liquid flows through the internal pores from the cooling liquid injection part to the working part contacting part.
このように構成された研摩砥石は、外表部の気孔を接着

を形作ることになる。In the polishing wheel configured in this way, by closing the pores on the outer surface with adhesive, the internal pores are continuous to form a coolant passage that directly connects the coolant injection part and the workpiece contact part. . That is, the adhesive applied to the outer surface of the abrasive wheel forms the wall of the coolant passage connecting the coolant injection part and the workpiece contact part.
そして、本発明の研摩砥石は従来の研摩砥石と同様に研

注出する。The polishing machine is provided with a structure for injecting a cooling liquid supplied from a cooling liquid injection device into the polishing wheel. When performing polishing, a cooling liquid supplied from a polishing liquid injection device is injected into the inside of the grinding wheel from a cooling liquid injection part of the polishing wheel. The coolant injected into the grinding wheel passes through pores that communicate with each other inside the grinding wheel, and flows to the outer periphery of the grinding wheel where it comes into contact with the workpiece.

研摩部位に冷却液を供給することができる。For this reason, a cooling liquid is supplied to the polishing area where the outer circumference of the polishing wheel I and the workpiece come into contact, cooling and lubricating the polishing area, cleaning the polished surface of the workpiece, and protecting the polishing wheel. In this case, the cooling liquid does not leak out from both sides of the polishing wheel 2 that are blocked with the adhesive Jl', y/, and a large amount of the cooling liquid can be supplied to the polishing area. By supplying the cooling liquid directly from the inside of the grinding wheel to the part to be polished, even if the area of the part of the grinding wheel that comes in contact with the workpiece is large, the cooling liquid can be distributed over the entire part to be polished. Even if it is difficult to pour cooling liquid into the polished area from the outside due to the shape of the object, the cooling liquid can be supplied to the polished area without being restricted by the workpiece.
