The abrasive and grinding tool industry mainly involves three categories of products: one is ordinary, including corundum series and silicon carbide, resin, ceramics, etc.
Abrasive is a material that plays a cutting role in grinding, grinding, and polishing. Grinding tools are tools used for grinding, polishing, and polishing. Abrasive tools are widely used in mechanical manufacturing and other metal processing industries, as well as for processing non-metallic materials such as ceramics, glass, and stone.
The abrasive and grinding tool industry mainly involves three categories of products: one is ordinary, including corundum series and silicon carbide, resin, ceramics, etc. The second is to apply grinding tools, including sanding cloth, sandpaper, sanding belt, etc. The third is superhard materials, mainly diamond, cubic boron nitride, and their products. Grinding is an irreplaceable and gradually expanding machining method in mechanical processing. There are also cases in the sanitary ware industry where a small amount of abrasives and grinding tools are used.
It is understood that the abrasive used is mainly used for two stages of the firing process. One is used for grinding, cutting, and polishing finished products; Secondly, for cost and quality reasons, it is used for kiln furniture reprocessing.
The products that use abrasive grinding tools mainly include toilets, toilets, basins, and columns. Because sanitary ceramic products are fired products, the subsequent firing is crucial. For the fired finished products, some have various minor defects, some deviate from the relevant standard values, and some need to be polished and cut for installation convenience.
Abrasive and grinding tools suffer from problems and omissions in various aspects such as modeling, mud shrinkage, kiln frame support, and semi-finished product inspection. The bottom of the toilet product is uneven and needs to be ground with a grinder to pass.
Due to various reasons such as firing, kiln installation, molds, and kiln equipment, some hanging and standing toilet products may have uneven back surfaces (referring to walls or installation surfaces) or individual sizes exceeding the standard. It is necessary to use a dedicated grinder to fully or partially polish the back surface to ensure that the installation surface on the back is flush, while also ensuring that the product meets the size requirements of various standards.
Basin and water tank products may have adhesion, burrs, or unevenness on the lower edge of the basin on the countertop, the upper edge of the basin under the table, the bottom of the artistic bowl, and the upper edge of the water tank. They need to be polished with abrasive tools such as grinders and angle grinders to be considered qualified.
In order to ensure easy molding and maintain the appearance of some ceramic columns in bowl products during firing, it is necessary to leave a 'supporting surface' on the back that is consistent with the blank body. However, this part needs to be cut off in the finished product to ensure ease of installation.
The firing process is a critical step in product formation. During the high-temperature firing process of 14500 degrees Celsius, various kiln furniture (including scaffolding, brackets, beams, columns, etc.) are also subjected to high-temperature baking on the kiln car. Over time, deformation, damage, and other problems may occur.
It is reported that the consumption of abrasive tools accounts for about 5% -10% of the total cost of ceramic products (the proportion of low value-added ceramic products will increase, otherwise it will decrease). For example, grinding enterprises specializing in rolling cutters, trimming wheels, cutters, metal grinding blocks, and ordinary silicon carbide grinding blocks will be affected.
