Description
본 고안은 연마포지(coated abrasives)를 접착하여 구성된 연마휠에 관한 것으로서, 더욱 상세하게는 압축 몰딩 기술로 연마휠의 백패드를 제조하는데 있어서 유연성을 부여하여 연삭감이 좋으며, 중량이 가벼워 취급이 용이한 연마휠의 백패드에 관한 것이다.The present invention relates to a polishing wheel formed by adhering coated abrasives, and more particularly, a compression feeling technique provides flexibility in manufacturing a back pad of a polishing wheel, and has a good feeling of grinding. It relates to a back pad of an easy polishing wheel.
일반적으로 그라인딩 휠과 같은 수지 접착형 연마 제품(resin-bondedabrasive article)은 보통 액체 수지 재료와 분말 수지를 분리된 연마 그레인이나 그리트 입자들과 혼합하여, 적당한 온도 조건하에서 이 혼합물을 압착하므로써 제조된다. 혼합물에는 예를 들어 충전재, 경화재(curing agent), 습윤제(wetting agent) 그리고 여러 가지 금속 분말들이 포함될 수도 있다. 액체 수지를 포함한 혼합물의 건조 부분을 용매화시키는 숙성 시기(aging period)가 보통 압착 전에 필요하다.Resin-bondedabrasive articles, such as grinding wheels, are generally made by mixing a liquid resin material and a powdered resin with separate abrasive grains or grit particles and pressing the mixture under suitable temperature conditions. The mixture may include, for example, fillers, curing agents, wetting agents and various metal powders. An aging period of solvating the dried portion of the mixture including the liquid resin is usually required before compression.
연마 제품의 제조에서, 연마 그레인 입자(abrasive grain particle)들을 결합할 필요가 있으며, 그 결과로 제품을 몰드할 수도 있고 그 밖에 다르게는 경화 공정 전에 처리할 수도 있다. 원하는 모양으로 제품을 경화시키기 위하여 경화 공정 동안 열을 가한다. 이상적인 임시 바인더는, 비경화 연마 제품에 그린 강도(green strength)를 제공하며, 제조 계획에 있어서 숙성 단계가 필요 없으며 압축 몰딩(냉간 프레스) 또는 고온 프레스 작업들 중 어느 하나에 유용한 것과 같은 가변성을 제공하며, 그레인이 연마 제품의 몰딩에 앞서 저장될 때 연마 그레인의 비가역 응집 작용(irreversible agglomeration)을 일으키지 않게 한다. 그린 강도는 연마 제품의 경화 촉진을 위하여 몰드로부터 비경화 연마 제품을 제거하고 제품을 이송하는데 있어서 중요할 뿐만 아니라, 특히 정확한 그라인딩 휠과 같은 원하는 형상을 보전·유지하는데 중요하다.In the manufacture of abrasive products, it is necessary to combine abrasive grain particles, as a result of which the product may be molded or otherwise processed prior to the curing process. Heat is applied during the curing process to cure the product to the desired shape. Ideal temporary binders provide green strength for uncured abrasive products, require no maturation step in manufacturing planning, and provide variability such as those useful for either compression molding (cold press) or hot press operations. And does not cause irreversible agglomeration of the abrasive grains when the grains are stored prior to molding of the abrasive product. Green strength is important not only in removing the uncured abrasive product from the mold and conveying the product in order to promote hardening of the abrasive product, but also in particular in preserving and maintaining a desired shape such as an accurate grinding wheel.
연마 제품을 접착하기 위한 유기 용매(organic solvent solution)로서 페놀 노볼락 수지(phenol novolac resin)가 사용된다.Phenol novolac resin is used as an organic solvent solution for bonding abrasive products.

The back pad 20 is comprised.
그런데, 유리섬유(22)로만 이루어진 백패드(20)는 기재가 두꺼워 중량이 무거우며, 제조 단가가 고가이다. 또한, 유리섬유(22)가 빳빳하여 한정된 곳만의 연삭이 이루어진다는 문제점이 있었다.By the way, the back pad 20 made of only the glass fiber 22 has a thick base material, which is heavy and expensive to manufacture. In addition, there was a problem that the grinding of the glass fiber 22 is limited to only a limited place.
본 고안은 상기한 바와 같은 결점을 해소시키기 위하여 안출된 것으로서, 연마휠의 백패드를 소량의 유리섬유에 소량의 카본섬유를 적층하여 압착 형성시킴으로서, 유연성이 부가되어 연삭감이 좋아진 백패드는 굴곡이 심한 곳의 연마도 가능하며, 중량이 가볍고 제조 단가가 저렴한 연마휠의 백패드를 제공하는 것을 그 목적으로 한다.The present invention was devised to solve the above-mentioned drawbacks, and by forming a small amount of carbon fiber by laminating a small amount of carbon fiber on the back pad of the polishing wheel, the flexibility of the back pad is improved due to the added flexibility. It is also possible to grind these severe areas, and to provide a back pad of a grinding wheel that is light in weight and inexpensive to manufacture.
상술한 목적을 달성하기 위한 본 고안은, 연마포지(coated abrasives)와 백 패드로 구성되는 연마휠에 있어서, 백패드가, 적어도 하나 이상의 유리섬유에 적어도 하나 이상의 카본섬유를 가열 압착하여, 유연성이 부가되어 굴곡면을 균일하게 연마할 수 있으며 중량이 가볍게 형성되는 연마휠의 백패드를 제공한다.The present invention for achieving the above object, in the polishing wheel consisting of coated abrasives (coated abrasives) and the back pad, the back pad is heat-compressed at least one or more carbon fibers to at least one glass fiber, It is added to provide a back pad of the polishing wheel that can be polished uniformly curved surface and is lightly formed.
