The characteristics of carbide tools and high-speed steel tools are

(1) High-speed steel tool: sharp blade, poor rigidity, soft and difficult to break, easy to wear, cheap, and not enough machining accuracy, mainly used for workpieces with low hardness of materials. (2) Carbide tool: hard and brittle, high temperature resistant, mainly used for machining workpieces with high hardness. Cemented carbide tools are not resistant to impact, so they need to be processed at a high speed, otherwise they are prone to chipping. According to the characteristics of high-speed steel, it can be used in the following situations: ①When high-speed machining cannot be performed; ②When the rigidity of the machine tool is poor; ③When the tool cost is expected to be cheap; ④When machining accuracy is not required.

What are the characteristics of CNC knives?

CNC tool materials include high-speed steel (divided into W series high-speed steel and Mo series high-speed steel), cemented carbide (divided into tungsten-cobalt, tungsten-titanium-cobalt and tungsten-titanium-tantalum (niobium) cobalt), ceramics (pure alumina) and TiC additions), cubic boron carbide and polycrystalline diamond. The material for making the tool must have high high temperature hardness and wear resistance, necessary bending strength, impact toughness and chemical inertness, good manufacturability, and not easy to deform. According to the requirements of CNC machining for tools, the general principle of selecting tool materials is to choose carbide tools as much as possible. Before the 1980s, high-speed steel was in the leading position. After the 1990s, cemented carbide surpassed high-speed steel. In recent years, many new varieties of cemented carbide have appeared, making cemented carbide tools widely used in milling, drilling, reaming, and filing. Therefore, whenever the processing conditions allow the use of carbide tools, try not to use high-speed steel tools. When necessary, ceramic, cubic boron nitride and diamond tools with better performance can also be selected in a targeted manner.

How important is the choice of CNC tools?

1. The most important thing in processing is the tool When any one tool stops working, it means that production has come to a standstill. But that doesn't mean every knife has the same importance. The tool with the longest cutting time has a greater impact on the production cycle, so under the same premise, more attention should be paid to this tool. In addition, attention should also be paid to the machining of critical components and tools with tight machining tolerances. In addition, tools with relatively poor chip control, such as drills, grooving tools, and threading tools, should also be paid attention to. Downtime due to poor chip control. 2. Match with the machine tool There are right-hand and left-hand knives, so choosing the right knives is very important. In general, right-hand tools are suitable for machines with counterclockwise rotation (CCW) (as viewed in the direction of the spindle); left-hand tools are suitable for machines with clockwise rotation (CW). If you have several lathes, some holding left-handed tools that are left- and right-handed compatible, choose left-handed tools. For milling, people generally tend to choose more versatile tools. However, although such tools cover a larger machining range, they also immediately lose the rigidity of the tool, increase the deflection of the tool, reduce the cutting parameters, and are more likely to cause machining vibration. In addition, the manipulator of the machine tool to change the tool also has restrictions on the size and weight of the tool. If you purchased a machine tool with a through hole for the spindle, please also choose a tool with a through hole for the cooling.

The difference between CNC tools and blades

1) High-precision manufacturing quality In order to stably process the surface of high-precision parts, stricter requirements than ordinary tools are put forward for the manufacture of tools (including tool parts) in terms of accuracy, surface roughness, and geometric tolerances, especially indexable tools. The repeatability of the size of the insert tip (cutting edge) after indexing, the size and accuracy of the key parts such as the cutter body groove and positioning parts, and the surface roughness must be strictly guaranteed. And dimensional measurement, the base surface machining accuracy should also be guaranteed. (2) Optimization of tool structure The advanced tool structure can greatly improve the cutting efficiency. For example, high-speed steel CNC milling tools have adopted wave-shaped edges and large helix angle structures in structure. The replaceable and adjustable structure, such as the internal cooling structure, cannot be applied by ordinary machine tools.

The current situation of the development of CNC cutting tools

The importance of machining tools to the production of the manufacturing industry is well known. The machining and metal cutting processes involved in the production process are very common. Various types of standard and non-standard tools are used in the processing. Quality directly affects whether the required qualified products can be successfully processed, and affects processing and production efficiency. In view of the importance of non-standard tool management to production and the complexity of tool management, a professional CNC tool manufacturer should be selected when considering product processing plans.    In finishing and many key processes, there are many varieties of non-standard tools, many specifications, small quantities, and expensive orders; the rational use and selection of tools can not only save production costs. And it can improve the production and processing efficiency of the product.   Non-standard knives are high-performance knives newly developed in my country in recent years. Although some companies have made some progress, the overall level of development is still worrying. For example, most of the tool manufacturing companies have insufficient technological development capabilities; insufficient research on materials and processed materials, poor tool application problem solving capabilities; lack of a complete processing parameter database; lack of systematic tool product development.

The difference between CNC tools and blades

CNC tools are used in high-performance and high-precision CNC machine tools. In order to achieve stable and good processing efficiency, CNC tools generally have higher requirements than ordinary tools in terms of design, manufacture and use. The main difference between CNC tools and blades is in the following aspects.    (1) High-precision manufacturing quality   In order to stably process the surface of high-precision parts, stricter requirements than ordinary tools are put forward for the manufacture of tools (including tool parts) in terms of accuracy, surface roughness, and geometric tolerances, especially indexable tools. The repeatability of the size of the insert tip (cutting edge) after indexing, the size and accuracy of the key parts such as the cutter body groove and positioning parts, and the surface roughness must be strictly guaranteed. And dimensional measurement, the base surface machining accuracy should also be guaranteed.   (2) Optimization of tool structure   The advanced tool structure can greatly improve the cutting efficiency. For example, high-speed steel CNC milling tools have adopted wave-shaped edges and large helix angle structures in structure. The replaceable and adjustable structure, such as the internal cooling structure, cannot be applied by 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, high-strength alloy steel is used for the tool body material of many CNC tools, and heat treatment (such as nitriding and other surface treatment) is carried out, so that it can be suitable for large cutting amount, and the tool life is also short. can be significantly improved (normal knives generally use quenched and tempered medium carbon steel). As for the cutting edge material, CNC cutting tools use various new grades of cemented carbide (fine particles or ultrafine particles) and superhard tool materials. (4) Selection of reasonable chip breaker   The tools used in CNC machine tools have strict requirements on chip breakers. During processing, if the tool does not chip, the machine tool cannot work normally (some CNC machine tools and cutting are carried out in a closed state). Therefore, regardless of CNC turning, milling, drilling or boring machines, the blades are optimized for different processing materials and procedures. Reasonable cutting. The chip geometry enables stable chip breaking during cutting. (5) Coating treatment on the surface of the tool (blade)   The emergence and development of tool (blade) surface coating technology is mainly due to the emergence and development of CNC tools. Since coating can significantly improve tool hardness, reduce friction, improve cutting efficiency and service life, more than 80% of all kinds of carbide indexable CNC tools have adopted coating technology. The coated carbide inserts can also be used for dry cutting, which also creates favorable conditions for environmental protection and green cutting.

Modern high-efficiency cutting tools favored

The tool industry is developing rapidly. Today, due to the high frequency of tool replacement, the demand is still large. In recent years, the manufacturing industry in developed countries has adopted a large number of modern high-efficiency cutting tools to improve labor productivity and save costs. With the development of the manufacturing industry, all countries take the development of modern high-efficiency tools as an important means to improve the competitiveness of the manufacturing industry. According to statistics published by multinational groups, the annual cutting cost of the global manufacturing industry reaches more than 400 billion US dollars, of which the tool cost is about 20 billion US dollars. In recent years, the manufacturing industry in developed countries has adopted a large number of modern high-efficiency cutting tools to improve labor productivity, saving the manufacturing industry up to 100 billion US dollars each year, which is far higher than the investment in tools. Therefore, all countries regard the development of modern high-efficiency tools as an important means to improve the competitiveness of the manufacturing industry. The concept that cutting tools are productivity, not consumables in the processing process, has formed a consensus in developed countries, and the proportion of cutting tool consumption in manufacturing costs has reached 3~4. At present, various enterprises in our industry have established research and development centers, engineering centers, etc. under various names, but few of them can research and develop the basic technology of modern high-efficiency tools.
