The present invention relates to a method for producing abrasive grindstones having increased polishing efficiency.
죵래의 연마지석은 주재료가 연마재와 결합제로서 연마재로는 인조 코론덤(Aritifical Alumina)과 탄화규소(Silicon Carbide)이며 결합제는 도기질 재료로서 도석, 점토, 장석, 활석, 석회석, 마그네시아, 법랑 등을 미립자로 분쇄하여 사용하고 있으며 기공제로서는 나프탄렌, 석유수지, 톱밥, 호도 껍질등을 사용하여 왔으나 나프타렌, 석유수지 등은 원가 상승의 요인이 되며 톱밥이나 호도 껍질 등은 가격은 저렴하나 불량율이 많아 생산성의 저하를 초래하여 왔다.The main abrasives are the abrasives and binders, which are artificial alumina and silicon carbide, and the binders are porcelain, clay, feldspar, talc, limestone, magnesia and enamel.

3) 제조공정3) Manufacturing process
상기와 같은 조성으로 배합으로 소정의 규격품으로 성형건조 후 850-1,350℃의 고온에서 규격에 따라 1-30시간 소성하여 제조하는 것이다.It is manufactured by baking for 1-30 hours according to the specifications at a high temperature of 850-1,350 ℃ after molding and drying to a predetermined standard product by mixing in the composition as described above.
소성 방법은 규격별 소성커브에 의거 소성하는데 대형인 경우는 시간당 50℃로 하여 1,250℃까지 가열한 후, 1,250℃에서 3시간 지속한후 시간당 80℃로 냉각한다. 소성 공정에서 배합시 물은 완전 증발되고 덱스트린은 타서 없어지며 세라믹 본드와 기공제는 용융 결합되어 비트리 파이트화(공유리화)된다.The firing method is fired based on the firing curve according to the standard. In the case of a large size, it is heated to 1,250 ° C. at 50 ° C. per hour, and then cooled to 80 ° C. per hour at 1,250 ° C. for 3 hours. In the firing process, the water is completely evaporated, the dextrin burns off, and the ceramic bonds and the pore are melt bonded to be vitrified.
기공제의 역활과 기능은 진주암, 흑요석, 송지석 등 화산암, 및 유리질 물질을 급속 가열 팽창 시켜서 된 것으로 다공질 기밀성의 소기포로 구성된 소립자 형태의 모래의 1/15-1/20정도의 경량성이 우수한 물질이다.The function and function of the pore agent is the rapid heating and expansion of volcanic rocks such as pearl rock, obsidian, and pine stone, and glassy materials, and is excellent in lightness of 1 / 15-1 / 20 of small particle type sand composed of porous airtight small bubbles. It is a substance.
기공제의 특성은 겉보기 비중이 0.06gr-0.5gr이며 성형시에는 충진제로서 성형강도를 높여주며 소성시에는 용융 되여 기공을 형성하며 세라믹 본드와 작용하여 결합제의 역활도 하는 것이다.The specific properties of the pore are 0.06gr-0.5gr of apparent specific gravity, which increases the molding strength as a filler during molding, melts during firing to form pores, and acts as a binder by acting as a ceramic bond.
이와 같은 본 발명의 화산암 또는 유리질 기공제 사용의 작용 효과는 기공제가 성형시 그림(1)과 같은 형상을 하고 있다가 고온 가열 하면 그림(2)와 같은 형상으로 변화되어서 기공제가 차지하고 있던 부분은 공간을 형성하게 되여 전체적인 형상은 스폰지 모양의 형태가 되며 연삭 작업시 형성 된 기공사이로 연삭찌꺼기가 침입 되므로 절삭 작업효율을 증대시킬 수 있으며 가공도중 마찰로 인하여 발생되는 마찰열을 줄일 수 있으므로 지석의 균열방지 및 피연삭물의 변질을 방지한다.The effect of using the volcanic rock or the glassy pore of the present invention is that the pore has a shape as shown in Fig. 1 at the time of molding, but changes to a shape as shown in Fig. 2 when heated at a high temperature. Since the overall shape becomes a sponge-like shape, and the groundwork formed during the grinding work intrudes the grinding debris, the cutting work efficiency can be increased, and the frictional heat generated by the friction during processing can be reduced, thus preventing the cracking of the grindstone. Prevent deterioration of the workpiece.
또한 기공제를 사용하므로서 제품 중량을 가볍게 할 수 있어서 회전에서 생기는 원심력을 적게하기 때문에 내회전력이 크고 안전도를 높일 수 있는 것이다. 따라서 동력 부하를 적게하기 때문에 전력비를 줄일 수 있는 것이다.In addition, by using a pore agent, the weight of the product can be lightened, thereby reducing the centrifugal force generated from the rotation, thereby increasing the rotation resistance and increasing the safety. Therefore, the power load can be reduced because the power load is reduced.
또 한가지의 두드러진 특징은, 전량 수입에 의존하고 있는 아루미나, 탄화규소 등 연마재를 본 기공제의 사용으로 30-40%절감할 수 있으므로 외화 절약과 원감 절감에 큰 효과가 있는 것이다.Another notable feature is that the abrasives such as alumina and silicon carbide, which depend on the total amount of imports, can be reduced by 30-40% with the use of this pore agent, which is a great effect for saving foreign currency and reducing original feelings.
