How important is the choice of CNC tools?

1. The most important thing in processing is the tool When any one tool stops working, it means that production has come to a standstill. But that doesn't mean every knife has the same importance. The tool with the longest cutting time has a greater impact on the production cycle, so under the same premise, more attention should be paid to this tool. In addition, attention should also be paid to the machining of critical components and tools with tight machining tolerances. In addition, tools with relatively poor chip control, such as drills, grooving tools, and threading tools, should also be paid attention to. Downtime due to poor chip control. 2. Match with the machine tool There are right-hand and left-hand knives, so choosing the right knives is very important. In general, right-hand tools are suitable for machines with counterclockwise rotation (CCW) (as viewed in the direction of the spindle); left-hand tools are suitable for machines with clockwise rotation (CW). If you have several lathes, some holding left-handed tools that are left- and right-handed compatible, choose left-handed tools. For milling, people generally tend to choose more versatile tools. However, although such tools cover a larger machining range, they also immediately lose the rigidity of the tool, increase the deflection of the tool, reduce the cutting parameters, and are more likely to cause machining vibration. In addition, the manipulator of the machine tool to change the tool also has restrictions on the size and weight of the tool. If you purchased a machine tool with a through hole for the spindle, please also choose a tool with a through hole for the cooling.

Modern high-efficiency cutting tools favored

The tool industry is developing rapidly. Today, due to the high frequency of tool replacement, the demand is still large. In recent years, the manufacturing industry in developed countries has adopted a large number of modern high-efficiency cutting tools to improve labor productivity and save costs. With the development of the manufacturing industry, all countries take the development of modern high-efficiency tools as an important means to improve the competitiveness of the manufacturing industry. According to statistics published by multinational groups, the annual cutting cost of the global manufacturing industry reaches more than 400 billion US dollars, of which the tool cost is about 20 billion US dollars. In recent years, the manufacturing industry in developed countries has adopted a large number of modern high-efficiency cutting tools to improve labor productivity, saving the manufacturing industry up to 100 billion US dollars each year, which is far higher than the investment in tools. Therefore, all countries regard the development of modern high-efficiency tools as an important means to improve the competitiveness of the manufacturing industry. The concept that cutting tools are productivity, not consumables in the processing process, has formed a consensus in developed countries, and the proportion of cutting tool consumption in manufacturing costs has reached 3~4. At present, various enterprises in our industry have established research and development centers, engineering centers, etc. under various names, but few of them can research and develop the basic technology of modern high-efficiency tools.
