1. Definition of CNC tools:
CNC cutting tools refer to the general term for various cutting tools used in conjunction with CNC machine tools (CNC lathes, CNC milling machines, CNC drilling machines, CNC boring and milling machines, machining centers, automatic lines and flexible manufacturing systems).
2. Characteristics of CNC machine tools:
(1) It has good and stable cutting performance. The tool has good rigidity and high precision, and can perform high-speed cutting and powerful cutting.
(2) The tool has a long service life. Tools use a large number of carbide materials or high-performance materials (such as ceramic blades, cubic boron nitride blades, diamond composite blades and coated blades, etc.). High-speed steel cutting tools are mostly used. Cobalt-containing, high-vanadium-containing, aluminum-containing high-performance high-speed steel and powder metallurgy high-speed steel).
(3) The cutting tools (blade) are interchangeable and can be replaced quickly. Tools can be automatically and quickly replaced to shorten auxiliary time.
(4) The tool accuracy is high. This tool is suitable for machining workpieces with higher precision, especially when using indexable inserts.
The cutter body and insert have high repeat positioning accuracy, so good processing quality can be obtained.
(5) The tool has reliable chip rolling and chip breaking performance. CNC machine tools cannot stop processing chips at will. Long chips that appear during machining can affect operator safety and machining efficiency. (Follow: Industrial Manufacturing WeChat public account for more practical information)
(6) The tool has the function of adjusting size. Tools can be pre-adjusted (tool setting) outside the machine or compensated in-machine to reduce tool changing and adjustment time.
(7) Tools can achieve serialization, standardization, and modularization. Tool serialization, standardization, and modularization are beneficial to programming, tool management, and cost reduction.
(8) Multi-functional compounding and specialization.
3. The main application areas of CNC tools include:
(1) Automobile industry The processing characteristics of the automobile industry are: first, large-volume, assembly line production, and second, relatively fixed processing conditions. In order to optimize production and improve quality and efficiency, the automotive industry has put forward very strict requirements on the processing efficiency and service life of cutting tools. At the same time, due to the use of assembly line operations, in order to avoid huge economic losses caused by the shutdown of the entire production line due to tool change, forced unified tool change is usually adopted. This also places high demands on the stability of tool quality.
(2) Aerospace industry The processing characteristics of the aerospace industry are: first, high processing accuracy requirements; secondly, material processing is difficult. Most of the parts materials processed in this industry are high-temperature alloys and nickel-titanium alloys with very high toughness and strength (such as INCONEL718, etc.).
(3) Most of the parts to be processed by large steam turbines, steam turbines, generators and diesel engine manufacturers are bulky and expensive. During the machining process, it is crucial to ensure the accuracy of the parts being processed and to reduce scrap, so imported tools are often used in these industries.
(4) Enterprises that use a large number of CNC machine tools often use imported cutting tools, which is easier to achieve the desired results.
(5) Foreign-funded enterprises among these enterprises tend to pay more attention to production efficiency and quality assurance. In addition, there are many other industries, such as the mold industry, military enterprises, etc., where the application of CNC tools is also very common.
