Classification and Characteristics of CNC Tools

CNC machining tools must adapt to the high speed, high efficiency, and high degree of automation of CNC machine tools. They should generally include universal tools, universal connecting tool holders, and a small number of special tool holders. The tool holder is connected to the tool and mounted on the machine tool power head, so it has been gradually standardized and serialized. There are many ways to classify CNC tools.

Classification of CNC Tools

1.    Classification according to the structure of CNC lathe tools

• Integral type;

• Inlaid type, using welding or machine clamp connection. Machine clamp type can be divided into non-indexable and indexable;

• Special types, such as composite tools, shock-absorbing tools, etc.

2.    Classification based on materials used to make tools

• High-speed steel cutting tools;

• Carbide cutting tools;

• Diamond cutting tools;

• Cutters are made of other materials, such as cubic boron nitride cutters, ceramic cutters, etc.

3.    Classification according to cutting technology

• Turning tools, including cylindrical, inner hole, thread, cutting tools, etc.;

• Drilling tools, including drill bits, reamers, taps, etc.;

• Boring tools;

• Milling tools, etc.

Characteristics of CNC Tools

1.    Good rigidity (especially roughing tools), high precision, small vibration resistance and thermal deformation;

2.    Good interchangeability, easy to change tools quickly;

3.    Long service life, stable and reliable cutting performance;

4.    The size of the tool is easy to adjust to reduce tool change and adjustment time;

5.    The tool should be able to reliably break or roll chips to facilitate the removal of chips;

6.    Serialization and standardization to facilitate programming and tool management.
