国内不锈钢铸造广泛应用于阀门、泵、船用五金、汽车零件、管道零件等各个领域，机械加工用的磨具、地质钻头及石材锯切工具的制造工艺水平已有很大提高。产品已形成系列化、标准化，品种规格齐全，产品质量稳定，部分产品在国际市场上具有一定的竞争力。为满足国内外工具市场的需要，必须加快新产品的开发，提高产品质量，增加品种，提高产量。近几年来，阀门、泵、船用五金、汽车零件、管道零件的加工领域对金刚石工具的需求量逐年增加，目前，这些产品国内还是依赖进口，因此必须尽快开发出高质量的各种系列的工具，以替代进口。为保证其产品质量，必须加快新技术、新工艺的推广，如真空焊接技术、电火花烧结技术、金刚石均布技术、金刚石镀铱技术及金属化粘结技术、激光焊接工艺等。

Domestic stainless steel casting is widely used in valve, pump, marine hardware, automobile parts, pipeline parts and other fields. The manufacturing technology level of abrasives, geological drills and stone sawing tools for mechanical processing has been greatly improved. Products have formed a series of standardization, complete varieties and specifications, product quality is stable, some products have a certain competitiveness in the international market. In order to meet the needs of tool market at home and abroad, it is necessary to speed up the development of new products, improve product quality, increase varieties and increase production. In recent years, the demand for diamond tools in the fields of valve, pump, marine hardware, automobile parts and pipeline parts has increased year by year. At present, these products still rely on imports in China. Therefore, it is necessary to develop high-quality series of tools as soon as possible to replace imports. In order to ensure the quality of products, it is necessary to speed up the promotion of new technologies and technologies, such as vacuum welding technology, spark sintering technology, diamond uniform distribution technology, diamond iridium plating technology, metallization bonding technology, laser welding technology, etc.
