A complete list of CNC tools, some of which you have never used!

Overview of CNC tools 

1. Definition of CNC tool:

 CNC tools refer to the general term for various 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. Features of CNC machine tools:

1) It has good stable cutting performance. The tool has good rigidity and high precision, and can carry out high-speed cutting and powerful cutting.

2) The knife has a higher life. The cutting tool uses a large number of cemented carbide materials or high-performance materials (such as ceramic blades, cubic boron nitride blades, diamond composite blades and coated blades, etc.). High-speed steel tools use high cobalt. , High-vanadium, aluminum-containing high-performance high-speed steel 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, and the auxiliary time can be shortened.

4) The knife has high precision. The tool is suitable for processing high-precision workpieces, especially when indexable inserts are used.

The repetitive positioning accuracy of the cutter body and the blade is high, so good processing quality can be obtained.

5) The cutter has reliable chip rolling and chip breaking performance. The CNC machine tool cannot be stopped at will to process the chips. The long chips appearing in the processing will affect the safety of the operator and the processing efficiency.

6) The tool has the function of adjusting the size. The tool can be pre-adjusted outside the machine (tool setting) or compensated inside the machine to reduce the tool change adjustment time.

7) Tools can realize serialization, standardization and modularization. The serialization, standardization and modularization of tools are conducive to programming, tool management and cost reduction.

8) Multifunctional composite and specialization.

3. The main application areas of CNC tools include:

1) Automobile industry The processing characteristics of the automobile industry are firstly high-volume, assembly line production, and secondly, the processing conditions are relatively fixed. 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 the cutting tools. At the same time, due to the use of assembly line operation, in order to avoid the shutdown of the entire production line due to tool change and huge economic losses, a mandatory unified tool change method is usually adopted. This also puts forward unique and high requirements for the stability of tool quality.

2) Aerospace industry The processing characteristics of the aerospace industry are high precision processing requirements and difficult materials processing. Most of the parts and components processed in this industry are high-temperature alloys and nickel-titanium alloys (such as INCONEL718, etc.) with very high toughness and strength.

3) Most of the parts to be processed by large turbines, steam turbines, generators and diesel engine manufacturers are large and expensive. When processing, it is very important to ensure the accuracy of the processed parts and reduce waste. Therefore, in these industries Imported knives are often used here.

4) Enterprises that use more CNC machine tools As the saying goes, "a good horse is equipped with a good saddle", in order to improve processing efficiency and product quality, and to give full play to the use efficiency of CNC machine tools, it is often easier to achieve the expected results with imported tools.

5) Foreign-funded enterprises In these enterprises, they 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 CNC tools 

According to the tool structure, it can be divided into:

1) Integral type: the tool is integrated, manufactured from a blank, not divided;

2) Welding type: use welding method to connect, cutter bar;

3) Machine clamp type: The machine clamp type is divided into two types: non-indexable and indexable; usually the CNC tool adopts the machine clamp type! (4) Special types: such as compound cutters, shock-absorbing cutters;

According to the material used in the tool, it can be divided into:

1) High-speed steel tools;

2) Cemented carbide tools;

3) Ceramic tools;

4) Ultra-high pressure sintered body tools;

According to the tool processing method, it can be divided into: 

1) Turning tools: Divided into outer circle, inner circle, thread, grooving, cutting tool, etc.

2) Drilling tools; including drills, taps, reamers, etc.

3) Boring tool;

4) Milling tools; including face milling cutters, end mills, three-face milling cutters, etc.
