    • The present invention discloses a mold for manufacturing a cutting wheel. This mold for manufacturing a cutting wheel can be used to mold a disk shaped cutting wheel by putting the main material ceramic powder mixture and core material together in the mold followed by heating and pressing, prolongs the life of the cutting wheel by making the molding density as uniform as possible to improve the binding force of the main material ceramic and resin, and thus prevents shortening of life and excessive dust generation due to a vibration phenomenon when a cutting wheel is mounted on a hand grinder and rotated, and enables more precise cutting. The mold for manufacturing a cutting wheel of the present invention comprises a pressure-molding unit which is formed to uniformly press powder material on the top surface of the lower mold or the bottom surface of the upper mold for containing and molding the materials for manufacturing the cutting wheel, wherein said pressure-molding units 121 and 141 are formed on the top surface of the lower mold 120 or the bottom surface of the upper mold 140 and are made of wire mesh materials 121a and 141a.
    • 本发明公开了一种用于制造切割轮的模具。 用于制造切割轮的模具可以用于通过将主材料陶瓷粉末混合物和芯材放在模具中一起加热和加压来模制盘形切割轮,通过使成型密度延长切割轮的使用寿命 尽可能均匀,以提高主材料陶瓷和树脂的粘合力,从而防止当切割轮安装在手动研磨机上并旋转时由于振动现象而引起的寿命缩短和产生过多的粉尘,并且能够进行更精确的切割 。 用于制造本发明的切割轮的模具包括压模成型单元,其形成为均匀地将粉末材料压在下模的顶表面或上模的底表面上,用于容纳和模制用于制造 切割轮,其中所述加压成型单元121和141形成在下模具120的顶表面或上模具140的底表面上,并且由金属丝网材料121a和141a制成。

    • The present invention a method for manufacturing a cutting wheel and a cutting wheel manufactured by the same. It is a major object of the present invention to provide a product with nonwoven fabric excluded from the front and rear surfaces of the cutting wheel and a new manufacturing method by which it is possible to produce a product with nonwoven fabric excluded, so that it enables the producer to produce good-quality products and the consumer to be supplied with good-quality products at lower prices so as to be able to use cutting wheels with grinding and cutting actions maximized. The method for manufacturing a cutting wheel of the present invention comprises a mixture preparation process for mixing ceramic powder and resin; a core material preparation process of the core material for cutting a fiber glass material woven in textile form; a peel sheet preparation process of a vinyl material having a predetermined thickness; a core material curing process in which the core material is cured for desired time under desired temperature and desired pressure with the peel sheet adhered to the prepared core material; a molding process in which the powder mixture is put into a pair of the core materials and the cutting wheel is molded by pressurizing/heating; a peel sheet removal process for detaching the peel sheet; a sintering process in which a plurality of cutting wheels are put in a sintering furnace with space material inserted and laminated between core materials, and sintered for desired time under desired temperature and pressure; and a cooling process in which the cutting wheels that have carried out the sintering process are cooled for desired time.
    • 本发明是一种制造切割轮的方法及其制造的切割轮。 本发明的主要目的是提供一种从切割轮的前表面和后表面排除的非织造织物的产品,并且可以制造不含无纺布的产品的新的制造方法,从而使其能够 生产者生产优质的产品,消费者以更低的价格提供优质的产品,以便能够最大限度地利用切割轮的磨削和切割动作。 本发明的切割轮的制造方法包括将陶瓷粉末和树脂混合的混合物制备方法; 用于切割以纺织形式编织的玻璃纤维材料的芯材料的芯材制备方法; 具有预定厚度的乙烯基材料的剥离片制备方法; 芯材固化方法,其中芯材在所需温度和所需压力下固化所需时间,剥离片粘附到制备的芯材上; 将粉末混合物放入一对芯材中并通过加压/加热成型切割轮的成型工序; 用于剥离剥离片的剥离片去除工艺; 将多个切割轮放入烧结炉中并将空间材料插入并层压在芯材之间的烧结工艺,并在期望的温度和压力下烧结所需时间; 以及冷却过程,其中进行烧结过程的切割轮被冷却期望的时间。
