Overview of NC tools
1. Definition of NC tools:
CNC tools refer to the general term of various tools used in combination 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. Features of NC machine tools:
1) With good stable cutting performance, the tool has good rigidity and high precision, and can perform high-speed cutting and powerful cutting in CNC machining parts and CNC turning parts.
2) The tool has a high life. A large number of tools are made of cemented carbide materials or high-performance materials (such as ceramic blades, cubic boron nitride blades, diamond composite blades and coated blades). High speed steel tools are made of high-performance high speed steel with high cobalt, high vanadium, aluminum and powder metallurgy high speed steel.
3) The tool (blade) has good interchangeability and can be changed quickly. The tool can be changed automatically and quickly to shorten the auxiliary time.
4) The tool has high precision. The tool is suitable for processing high precision workpieces, especially when using indexable inserts
The tool body and blade have high repeated positioning accuracy, so good processing quality can be obtained.
5) The cutter has reliable chip curling and chip breaking performance. The NC machine tool can not be stopped at will to handle the chips. The long chips during processing will affect the safety and processing efficiency of the operator. (Attention: industrial manufacturing WeChat official account for more practical information)
6) The cutter has the function of dimension adjustment. The cutter can be preset outside the machine (tool setting) or compensated inside the machine to reduce the tool change adjustment time.
7) The tool can realize serialization, standardization and modularization The tool serialization, standardization and modularization are conducive to programming, tool management and cost reduction.
8) Multi functional composition and specialization.
3. The main application fields of NC tools include:
1) The processing characteristics of the automobile industry are: first, mass production and assembly line production; second, the processing conditions are relatively fixed. In order to optimize production, improve quality and efficiency, the automotive industry has put forward very stringent requirements for the machining efficiency and service life of tools. At the same time, due to the adoption of assembly line operation, in order to avoid the shutdown of the whole production line and huge economic losses caused by tool change, mandatory tool change is usually adopted. This also puts forward a unique high requirement for the stability of tool quality.
2) The processing characteristics of aerospace industry are as follows: first, the requirements for processing accuracy are high; second, the materials are difficult to process. The parts and components processed in this industry are mostly high temperature alloys and nickel titanium alloys (such as INCONEL718) with high toughness and strength.
3) Most of the parts to be processed by large turbine, steam turbine, generator and diesel engine manufacturers are bulky and expensive. It is essential to ensure the accuracy of the parts to be processed and reduce waste products during processing. Therefore, imported tools are often used in these industries.
4) As the saying goes, “A good horse needs a good saddle” in enterprises that use more CNC machine tools. In order to improve the processing efficiency and product quality, and give full play to the use efficiency of CNC machine tools, it is often easier to achieve the desired results by using imported tools.
5) In these enterprises, foreign-funded enterprises tend to pay more attention to the guarantee of production efficiency and quality. In addition, there are many other industries, such as mold industry, military enterprises and other applications of CNC tools are also very common.

Classification and characteristics of NC tools
According to the tool structure, it can be divided into:
1) Integral type: the cutter is integrated and made of one blank without separation;
2) Welding type: connected by welding, cutter bar;
3) Clamping type: Clamping type is divided into non indexable and indexable; Generally, NC tools are of machine clamp type! (4) Special types: such as compound cutter and shock absorbing cutter;
According to the material used by the tool, it can be divided into:
1) High speed steel cutter;
2) Carbide cutter;
3) Ceramic tools;
4) Ultra high pressure sintered tool;
It can be divided into:
1) Turning tools: including excircle, inner circle, thread, groove cutting tool, cutting tool, etc.
