The difference between CNC tool and ordinary tool in NC tool knowledge lecture

The difference between CNC tools and ordinary tools

CNC tools are applied on high-performance, high-precision CNC machine tools. In order to achieve stable and good machining efficiency, CNC tools are generally required to be higher in design, manufacture and use than ordinary tools. The main differences between CNC tools and general tools are as follows.

(1) High precision manufacturing quality

In order to stably process the surface of high-precision parts, the manufacturing of tools (including tool parts) is more strict than ordinary tools in terms of precision, surface roughness, and geometrical tolerances, especially for indexable tools. The repeatability of the blade tip (cutting edge) after indexing, the size and precision of the key parts such as the cutter groove and the positioning part, and the surface roughness must be strictly guaranteed, and at the same time, it is convenient for the tool to be set in the tool setting tool. And dimensional measurement, the processing accuracy of the base surface should also be guaranteed.

(2) Optimization of tool structure

The advanced tool structure can greatly improve the cutting efficiency. For example, the high-speed steel CNC milling tool has adopted the wave blade and the large spiral angle structure in structure, and the cemented carbide indexable tool adopts the internal cooling, the blade vertical type and the module. The interchangeable and adjustable structure, such as the internal cooling structure, is not applicable to ordinary machine tools.

(3) Wide application of high quality materials for cutting tools

In order to prolong the service life of the tool and improve the strength of the tool, many of the tool materials of the CNC tool are made of high-strength alloy steel and heat-treated (such as surface treatment such as nitriding), which makes it suitable for large cutting applications and tool life. Significantly improved (common tools are generally tempered medium carbon steel). On the tool edge material, CNC tools use a variety of new grades of carbide (fine or ultra-fine particles) and super-hard tool materials.

(4) Selection of reasonable chipbreaker

The tools applied on CNC machines have strict requirements on chipbreakers. During machining, the machine does not work properly due to continuous chipping (some CNC machine tools, cutting is performed in a closed state), so regardless of the CNC car, milling, drilling or boring machine, the blade is optimized for different processing materials and processes. The chip groove type enables stable chip breaking during cutting.

(5) Coating treatment on the surface of the cutter (blade)

The emergence and development of tool (blade) surface coating technology was mainly due to the emergence and development of CNC tools. Because coatings can significantly improve tool hardness, reduce friction, improve cutting efficiency and service life, coating technology is used in more than 80% of all types of carbide indexable CNC tools. The coated carbide inserts are also available for dry cutting, which also creates favorable conditions for protecting the environment from green cutting.
