그라인더의 휠페이퍼{Wheel paper of grinder}Wheel paper of grinder {Wheel paper of grinder}

본 고안은 가공물의 표면이나 타 부분을 매끄럽도록 연마하는 그라인더의 휠페이퍼에 관한 것으로, 특히 벨크로테입을 이용하여 회전지지판과 연마수단을 탈부착구조로 구성하고 두 종류의 연마편을 교대로 형성한 연마부재로 형성된 그라인더의 휠페이퍼에 관한 것이다.The present invention relates to a wheel paper of a grinder for smoothly polishing the surface or other parts of a workpiece, in particular, using Velcro tape The present invention relates to a wheel paper of a grinder comprising a rotating support plate and a polishing means having a detachable structure and formed of an abrasive member in which two kinds of abrasive pieces are alternately formed.

일반적으로, 금속이나 목재 또는 기타의 가공물의 표면을 매끄럽게 그라인딩 하기위하여 크기가 작으며 작업자가 운반이 간편하여 쉽게 현장에서 사용하고 있다. 또한 연마 기능과는 다르게 절단기구로도 사용이 가능하며 현재 여러가지가 개발사용되고 있다. 통상의 그라인더는 구동모우터와 직교를 이루며 형성되어진 연삭부재를 채결가능하도록 형성된 회전축에 원판상의 연마수단를 결속너트로 결합하여 소기의 가공 및 다듬질 또는 절단 작업을 이루게 하고 있다. 이러한 그라인더는 작업종류와 연마수단의 크기가 대체적으로 작게 형성되어 있어 교체의 작업을 자주 행하고 있다. 또한 연마수단은 대체적으로 샌드페이퍼라는 경도가 높고 거칠기가 있는 연마성이 우수한 모래를 특수한 재질의 종이에 강력한 접착제를 사용하여 고착시켜 놓은 것을 사용하게 되는데, 그라인드에서 사용하기 위해서는 원판형상으로 절단하여 회전지지판에 접착하여 사용하며, 일반적으로 사용되는 형상은 원판의 중심점을 지준으로 샌드페이퍼를 일정한 크기로 사각모양으로 절단하여 겹치도록 하여 접착시킨 것을 사용한다.In general, in order to smoothly grind the surface of metal, wood or other workpieces, the size is small and the worker is easy to carry and is easily used in the field. In addition, unlike the polishing function, it can be used as a cutting tool, and various developments are being used. Conventional grinders combine the grinding means of a disc with a binding nut on a rotating shaft formed to form a grinding member formed orthogonal to a driving motor to form a desired machining, finishing or cutting operation. Such grinders are generally formed with a smaller work type and a smaller grinding means, so that replacement work is frequently performed. In addition, the grinding means is a sand paper is used to adhere the sand of high hardness and roughness with high abrasiveness to the paper of a special material using a strong adhesive. In general, the shape used is the one that is bonded by cutting the sandpaper to a certain size and overlapping it with the center point of the disc.

이와같은 종래 그라인더의 휠페이퍼의 전형적인 일예가 도 1에 도시되어 있다.A typical example of such wheel paper of a conventional grinder is shown in FIG. 1.
