Design engineers have thankless jobs. They never stop spending energy to constrain tolerances and improve accuracy to fight failures and downtime. They have improved the design accuracy to about 1 micron year after year. They are perfect watchers. But when the tools are not properly balanced, their thorough and careful attention to detail creates waste.

In metal cutting processing, tool selection is almost a problem that every process engineer must face. There are many issues to consider when choosing a tool, and accordingly there are many principles, such as the efficiency principle, the machining accuracy principle, the stability principle, the economy principle, and so on. First talk about the principle of efficiency. The efficiency principle is inseparable from other principles, especially the economic principle. The main purpose of requiring efficiency is to ensure the economy of the entire process.

1. Factors affecting the selection of CNC tools. When choosing the type and specification of the tool, the following factors are mainly considered: (1) The nature of production. The nature of production here refers to the batch size of the parts, which mainly considers the impact on tool selection from the processing cost. For example, it may be cost-effective to use special tools in mass production, while in single or small batch production, it is more suitable to choose standard tools.

Before selecting and using diamond-coated tools, users must understand the following common sense about diamond-coated tools: Amorphous diamond (also known as diamond-like carbon-Annotation) coating is a carbon film deposited by the PVD process . It has both part of the SP3 bond of diamond and part of the SP2 bond of carbon; its film-forming hardness is very high, but it is lower than the hardness of diamond film; its thickness is also thinner than the diamond film we usually deposit.

Due to the impact of the financial turmoil, China's manufacturing industry has been in a slump since 2010, and the tool industry is of course no exception. Until the 18th National Congress of the Communist Party of China held in 2012, the emphasis on manufacturing was put forward and in the new wave of world economic integration, the accelerated transfer of global manufacturing to mainland China is the general trend, and China will gradually develop into a world-class manufacturing base. . Making China become the world's most promising tool market, production development...

In recent years, although my country's hardware tool industry has developed a lot, it lags far behind the development of the machine tool industry. According to data surveys, my country’s current annual tool sales are 14.5 billion yuan, of which cemented carbide tools account for less than 25%. This is not only a far cry from the product structure of the international market, but also cannot meet the increasing demand for cemented carbide tools by the domestic manufacturing industry. Increasing demand. At present, the imbalance of the tool structure means that the tools produced are not in line with the demand.
