The tool of CNC machine tool is one of the key factors to determine the machining quality and efficiency. According to different classification standards, the tools of CNC machine tools can be divided into many types. Common categories include the following:

1, according to the structural form of the tool classification:

Integral tool: Integral tool is made of a piece of material, its rigidity is good, suitable for processing requirements are not high or the cutting amount is not large occasions. This tool is usually suitable for small or simple machining tasks.

Welding tool: The blade of the welding tool is connected with the tool bar by welding, which is low in cost and can be easily replaced. However, due to the possible thermal stress in the welding process, which causes the blade to crack or fall off, its reliability is relatively low.

Mechanically clamped tool: The blade of the mechanically clamped tool is mechanically clamped on the tool bar, which can quickly replace the blade and is easy to standardize and serialize. The rigidity of this tool is good, suitable for the processing of large cutting amount, but because the structure of the mechanical clamping part is more complex, its cost is relatively high.

Hot-loading tool: Hot-loading tool is to heat the blade into the tool bar, and closely combine the two through the thermal expansion and contraction principle between the blade and the tool bar. The rigidity of this tool is good, suitable for large cutting amount processing, but its hot loading process is more complex, requiring higher operating skills.

Special forms of tools: In addition to the above common CNC machine tool, there are some special forms of CNC machine tool, such as forming turning tools, indexable turning tools, milling tools, etc. These special forms of tools each have their own unique advantages and disadvantages, suitable for different processing needs.

2, according to the material classification of the tool:

High-speed steel tool: high-speed steel is a commonly used CNC machine tool material, with good toughness and bending strength, suitable for processing low hardness materials. However, the heat resistance of high-speed steel is poor, and it is easy to wear and become soft when processing high-temperature materials.

Carbide tool: carbide is a kind of alloy material composed of tungsten, titanium, carbon and other elements, its high hardness, good wear resistance, suitable for processing high hardness materials. However, the impact resistance of cemented carbide is poor, and it is easy to crack.

Diamond tool: diamond is one of the hardest substances in nature, its wear resistance and heat resistance is excellent, suitable for processing high-temperature alloy, stainless steel and other high hardness, high wear-resistant materials. But the price of diamond is higher and it is vulnerable to chemical corrosion.

Ceramic tool: Ceramic tool is a kind of aluminum oxide, silicon nitride and other materials made of the tool, its high hardness, good wear resistance, good chemical stability, suitable for processing a variety of materials. However, the impact resistance of ceramic cutting tools is poor, and it is easy to crack.

3, according to the use of the tool classification:

Turning tool: Turning tool is a tool used for turning processing, according to different turning needs can be divided into external turning tool, internal turning tool, tank turning tool, etc.

Milling tool: Milling tool is used for milling tools, according to different milling needs can be divided into flat milling cutter, end milling cutter, keyway milling cutter and so on.

Drilling tool: Drilling tool is used for drilling tools, according to different drilling needs can be divided into straight shank drill, taper shank drill, drill and so on.

Boring tool: boring tool is used for boring tool processing, according to different boring needs can be divided into single-edge boring tool, double-edge boring tool and so on.

In addition to the above common classification methods, there are some other classification methods, such as according to the cutting edge shape, cutting amount and so on. In short, the selection of the right CNC machine tool needs to be comprehensively considered according to the actual situation, including processing materials, processing conditions, cutting dosage, production efficiency and so on.
