그리고 본 발명의 따른 커팅 휠은 세라믹 배합물에 상기 유황을 포함한 충진재를 사용하여 만든 것이다. And the cutting wheel according to the invention is made using a filler containing the sulfur in the ceramic blend.

이하 본 발명의 조성물 구성을 위한 실시 예를 아래에서 더 상세히 설명한다. Hereinafter, embodiments for the composition of the present invention will be described in more detail below.

본 발명의 조성물은 크게 연마제를 포함하는 세라믹 배합물과, 별도의 충진재로 이루어진다. The composition of the present invention largely consists of a ceramic blend containing an abrasive and a separate filler.

세라믹 배합물은 입자와 성격이 서로 다른 두 가지 이상의 세라믹 분말로 이루어지는바, Ceramic blends consist of two or more ceramic powders of different particle and character,

강한 성질의 세라믹 분말 1형(입자 메시#46) ------------ 65% 19.500㎏Ceramic powder type 1 (particle mesh # 46) of the strong property ------------ 65% 19.500㎏

연마제(Alumina Zirconia Abrasive; 입자메시#46)-------- 15% 4.500㎏Abrasive (Alumina Zirconia Abrasive; Particle Mesh # 46) -------- 15% 4.500㎏

로 이루어진 것이 대표적이다.It is typical that consists of.

상기와 같이 준비된 세라믹 분말은 세라믹 배합물 30㎏을 준비할 때의 실시 예이고, 그 비율은 중량비이다. The ceramic powder prepared as described above is an embodiment when preparing 30 kg of the ceramic blend, and the ratio is by weight.

한편, 충진재는 상기와 같이 준비된 30㎏의 세라믹 혼합물에 추가로 배합하기 위한 것으로, 세라믹 배합물 100중량부에 대하여,On the other hand, the filler is for further blending into the 30 kg ceramic mixture prepared as described above, with respect to 100 parts by weight of the ceramic blend,

산화철(#1 검정) 3.3중량부 0.990㎏Iron oxide (# 1 black) 3.3 parts 0.90.9 kg

유산(BA) 5.3중량부 1.590㎏Lactic acid (BA) 5.3 parts by weight 1.590 kg

빙정석(백색) 5.0중량부 1.500㎏Cryolite (white) 5.0 parts by weight 1.500 kg

액상수지 8.3중량부 2.490㎏8.3 parts by weight of liquid resin

분말수지 25.5중량부 7.650㎏25.5 parts by weight of powdered resin

카본(흑색) 0.5중량부 0.015㎏Carbon (black) 0.5 part by weight 0.015 kg

등유(일반) 0.2중량부 0.06㎏으로 이루어진다. It consists of 0.2 part 0.06 kg of kerosene (general).

이때, 본 발명에서는 상기의 내용물 외에 유황 0.2∼0.4중량부 즉, 0.060㎏∼0.120㎏을 더 추가하여 충진재를 완성하는 것이다. At this time, in the present invention, in addition to the above contents, sulfur is further added to 0.2 to 0.4 parts by weight, that is, 0.060 kg to 0.120 kg to complete the filler.

상기 비율(%)은 상기 세라믹 배합물 30㎏을 100으로 보았을 때의 비율이다. The ratio (%) is a ratio when the 30 kg of the ceramic compound is viewed as 100.

상기와 같은 비율의 내용물로 이루어진 충진재는 그 무게의 합이 약 13.464∼13.524㎏이 되며, 이를 앞서 준비한 세라믹 배합물 30㎏에 혼합하면 약 43.464∼43.524㎏이 되는 것이다. Filler consisting of the content of the above ratio is about 13.464 ~ 13.524kg the sum of the weight, it is about 43.464 ~ 43.524kg when mixed in 30kg of the ceramic blend prepared above.

이들 조성물을 혼합하기 위해서는 교반 날개 등이 준비된 전용 혼합용기에서 실시한다. In order to mix these compositions, it carries out in the special mixing container in which stirring blades etc. were prepared.

다음은 상기와 같이 준비된 조성물을 사용하여 본 발명의 커팅 휠을 제조하는 방법을 설명한다. The following describes a method of manufacturing the cutting wheel of the present invention using the composition prepared as described above.

도 3에서 보는 바와 같이 세라믹 배합물(11)과, 화이버 글라스 심재(12)와, 부직포(90) 등의 재료를 준비한 후, 커팅 휠이 원형으로 성형되도록 하는 별도의 몰드(20)에 상기 세라믹 배합물(11)과 심재(12)를 넣고 뚜껑(21)을 덮은 후, 약 20∼40℃의 조건에서 약 60∼90kg/㎠ 무게로 가열 압축한다. As shown in FIG. 3, the ceramic compound 11, the fiber glass core 12, the nonwoven fabric 90, and the like are prepared, and then the ceramic compound is placed in a separate mold 20 to form a cutting wheel in a circular shape. (11) and the core material 12 are put in and cover the lid 21, and it heat-compresses by the weight of about 60-90 kg / cm <2> on the conditions of about 20-40 degreeC.

이후, 압축 가열이 이루어진 커팅 휠은 여러 개를 한꺼번에 적층한 후, 소결로(전기로)에 넣고 약 180℃ 약 2kg/㎠ 의 무게 조건하에서 일정시간 소결시키는 소결과정을 거친 후 냉각하여 완성하게 되는 것이다. Then, the cutting wheel made of compression heating is laminated to several at once, and then put into a sintering furnace (electric furnace) after cooling the sintering process for a certain time under a weight condition of about 2kg / ㎠ about 180 ℃ is completed by cooling will be.

이는 통상의 커팅 휠 제조 방법과 같다. This is the same as a conventional cutting wheel manufacturing method.

그러나 본 발명의 커팅 휠용 조성물에 중요한 점은 상기 충진재에 유황이 포함되어 있기 때문에 제조과정의 소결 진행시 그 유황이 유산 바륨에 의해 생성되는 거품의 발생을 방지하게 되고, 따라서 유산 바륨이 몰드 내부에 펼쳐진 전체 세라믹 배합물에 고르게 분포될 수 있고, 밀도가 고른 커팅 휠을 생산할 수 있게 되는 것이다. However, an important point of the composition for the cutting wheel of the present invention is that since the filler contains sulfur, the sulfur prevents the generation of bubbles generated by the barium lactate during the sintering of the manufacturing process, and thus barium lactate is contained in the mold. It can be evenly distributed throughout the entire ceramic blend and produce a uniformly dense cutting wheel.

아울러 본 발명에서의 커팅 휠용 조성물로 제조된 커팅 휠은 유황이 포함되어 있기 때문에 절단 작업시 발생하는 열이 레진에 작용한다 하더라도 아황산가스를 중화시키기 때문에 인체에 유해한 독한 냄새의 발생을 예방하게 된다. In addition, since the cutting wheel made of the composition for the cutting wheel in the present invention contains sulfur, even if heat generated during the cutting operation acts on the resin, the sulfur is neutralized, thereby preventing the generation of harmful odors harmful to the human body.

위에서 상세히 설명한 바와 같은 본 발명은 세라믹 배합물과 충진재를 배합하여 커팅 휠 제조용 조성물을 준비하되, 상기 충진재에 유황을 섞어 만들었기 때문에 소결 작업시 유산 바륨의 거품발생을 예방하여 밀도가 더 균일한 커팅 휠을 생산하는데 유리한 장점이 있다. The present invention as described in detail above is to prepare a composition for preparing a cutting wheel by mixing the ceramic blend and filler, but because the sulfur is mixed with the filler to prevent the foaming of barium lactic acid during sintering operation more uniform cutting wheel There is an advantage in producing this.

뿐만 아니라 충진재에 포함된 유황은 커팅 휠을 핸드 그라인드에 장착하여 절단 작업을 할 때, 절단 마찰에 의해 열이 발생하여 레진에 작용하더라도 그 레진에서 발생할 아황산가스를 중화시키기 때문에 인체에 유독한 악성 냄새를 없애 환경 친화적인 상태로 만들기 때문에 좋은 것이다. In addition, sulfur contained in the filling material is harmful to human body because it neutralizes the sulfurous acid gas generated in the resin even when the cutting wheel is mounted on the hand grind and heat is generated by the cutting friction to act on the resin. It would be nice because it gets rid of the environment and makes it environmentally friendly.
