Achievements in the application of diamond tools
Time:2018-04-27
The application of diamond tools in the Chinese stone processing industry has achieved great success through nearly 20 years of development. The diamond cutting, grinding, and special-shaped tools for stone processing have gone from scratch, from imitation to substitution of imported products. The evolution of products sold around the world.
Taking Fujian Province as an example, it was the first province to produce tombstone stone exported to Japan. Tombstone stone products ordered by Japanese merchants in the 1990s have high gloss requirements and precise dimensional requirements. Therefore, the quality of processed diamond tools is required to be higher. These products are mainly imported from Japan Sanhe Company, such as diamond resin discs, diamond discs, polishing discs and soft discs. The technical difficulty of these abrasives, ranging from easy to difficult, is: diamond metal discs, diamond resin discs, polishing discs, soft discs, especially polishing discs or polishing discs, with the highest technical difficulty. The main difficulty is that in a certain period of time, the gloss of the polish must reach a certain index, and the gloss should be clear and bright. Therefore, at the time, the earliest order to begin to replace imported products on the market began with metal grinding discs and experienced a process of development from easy to difficult. The unit price of domestically produced 8 inch 50# metal grinding discs to the user was around RMB 400 (mostly RMB 30 is currently used). Finally, after several domestic manufacturers solved the technical problem of polishing plate gloss, they started from 1994. Stone diamond tool abrasive can basically replace imported products. However, due to disorderly price competition, product prices have been declining year by year, and this competition has also extended to neighboring Asian countries. In the Indian market in 1999, the export price (FOB) of a 2m ordinary low-cobalt diamond cutter produced in China was around US$450, which has now dropped to about US$150. As a result of low-price competition, the production cost of products continues to decline, but the average profit level of the industry also declines year by year.
This year, on the one hand, the state has made macro adjustments to the industrial structure. On the other hand, the influence of external conditions has caused export-oriented companies to have the following unfavorable factors: The depreciation of the US dollar against the yuan has directly caused the decline of corporate profits; the tax rebate rate has dropped, and the VAT paid has increased. The U.S. subprime mortgage turmoil has caused the U.S. market to weaken; as prices have risen, corporate operating costs have increased.
