Review the development of domestic hardware tool manufacturing industry

In developed countries, cemented carbide tools currently occupy the leading position of tools, with a proportion of 70%. High-speed steel cutting tools are being reduced by 1% to 2% per year, and the current proportion has fallen below 30%. The proportion of super hard tools such as diamond and cubic boron nitride is about 3%.

Among the tools used in the domestic hardware manufacturing industry, the proportion of cemented carbide tools has reached more than 50%, and the problem of disconnection between the supply and demand structure has become very serious. As a result, a large number of high-speed steel cutters that are surplus are exported at a low price or sold domestically. At the same time, high-efficiency carbide cutting tools have to rely on large amounts of imports. The import volume has increased from 0.9 billion US dollars in 2001 to 450 million US dollars in 2005. 3.6 billion yuan).

China's current annual sales of tools are 14.5 billion yuan, of which the proportion of cemented carbide tools is less than 25%, which is not only far from the structure of international market tool products, but also can not meet the growing demand for carbide cutting tools in the domestic manufacturing industry.

China currently produces about 80,000 tons of high-speed steel annually, accounting for about 40% of the world's total production, and consumes a large amount of valuable rare resources such as tungsten and molybdenum. This kind of blind expansion and low-level repetition has resulted in a large surplus of high-speed steel cutters and has to be sold at low prices, which has resulted in a large number of tool-manufacturing companies having low profitability.

Under such circumstances, China's independent research and development of CNC tool grinding machines is particularly urgent, and now Peking Machine Tool has produced a five-axis CNC tool grinder, which has the advantages of high precision, accurate positioning, wear resistance, low vibration, to meet the tool Manufacturing requirements are welcomed by the majority of customers as soon as the market is launched.
