This year's product structure innovation is endless, and various manufacturing enterprises have developed products with different structures and characteristics according to the needs of continuously subdivided users. Kenner launchedFPThe Groove Series features a unique single-screw wedge clamping system in which the blade is held by wedge compression instead of traditional screw holes, resulting in a non-porous design.

Chip control technology innovation

Chip control technology has always been a key problem in automated production, and Mitsubishi has launched a new technology based on low-frequency vibration cutting (LFV) special products. Low-frequency vibration technology solves the problems caused by chip entanglement in machining by making the servo shaft vibrate in the cutting direction, so that the vibration is synchronized with the spindle rotation and cutting at the same time, so as to break the chips and discharge them intermittently, thereby solving the problems caused by chip entanglement in machining, which is especially important in the processing of difficult-to-machine materials and automatic line production.

Product technology extension

Tool manufacturing enterprises use mature technologies accumulated over the years to extend to other application fields to develop new products, new processes and new technologies. For example, the gear processing precision expansion fixture developed by using the hydraulic tool holder liquid expansion clamping technology extends to the robot precision reducer processing and assembly tooling; exploitPCDThe precision of the tool precision manufacturing technology has been developedVSDGear honing grinding wheel dresser, shape accuracy can be reached0.001mm； exploitPSCzero-point positioning fixture developed by triangular pyramid positioning interface technology, etc.

Industry development characteristics

Review the whole thingCIMT2025Well-known tool companies and tool products at home and abroad were all present, and advanced technology, advanced technology, advanced products and advanced concepts competed on the same stage, showing the following characteristics:

（1）The technological gap between domestic and foreign products is gradually narrowing

In recent years, the cutting tool industry has entered a period of stable development, and the product technology has no cross-era inventions, but has been continuously optimized and innovated in details, which has left enough opportunities for the rapidly developing domestic cutting tool industry to catch up. In terms of tool materials, except for some difficult-to-process material tools, there is still a slight gap, domestic tools can basically meet the requirements of general material processing and reach the level of "running parallel" with foreign tools. In terms of tool manufacturing technology, with the introduction of advanced process equipment and the upgrading of domestic process equipment, the tool manufacturing process is basically synchronized with foreign tools. Such as the knives exhibited at this exhibition3DThe printing process has also begun to be widely used in China. In terms of product technology, with the continuous strengthening of R&D investment by domestic enterprises, the key bottleneck technology of some tools has been overcome, and the product technology can reach the international advanced level, such as damping and vibration damping tools, and many domestic enterprises exhibit such products. However, electrical combined products are still slightly backward compared with foreign countries.

（2）The cutting tool industry has entered an era of great integration

The cutting tool market has fully entered the era of intensive cultivation for users from extensive product sales. In the existing market environment, customers have become extremely valuable and rare resources, and once trust is established with customers, the pursuit of maximizing the utilization of customer resources has become a common goal of enterprises. However, it is almost impossible to rely entirely on the company's own products to meet customer needs, and it requires strong supply chain resources, through its own technical advantages, integrating industry process equipment, advantageous products and promotion platforms to create a full range of services for users. In this exhibition, Senla Tianshi Company and German Schonk Company exhibited at the same timeiTENDO²intelligent tool holder; Kenna Company of the United States used the booth to hold a technical seminar on "Gathering Momentum and Moving to the New" with many partners to jointly provide customers with products and services.

（3）Cutting tools are moving from product provision to value service

The cutting tool industry has fully entered the era of providing users with overall solutions, that is, providing users with value services. On the basis of in-depth exploration of user needs, domestic tool exhibitors in this exhibition exhibited overall solutions in different fields. Domestic enterprises such as Zhu Diamond, Jinlu, Tool Institute, Sentai Yingge, Oukeyi, Huarui, and Aoktai exhibited overall solutions for metal cutting in different industries, and Oukeyi also proposed the "general contracting of tools"+intelligent warehousing"; Zheng Zuan,REGO-FIXTotal solutions for tool loading and unloading were exhibited.

In short, it can be clearly seen from this exhibition that various tool companies are gradually transforming from traditional tool product suppliers to service providers that provide value to users, deeply excavate and refine the different needs of customers, and provide optimized solutions and value services. It is hoped that through the exhibition platform, we can communicate with each other, integrate with each other, learn from each other's strengths, and jointly provide efficient processing solutions for cutting processing users and provide value services for users, so as to realize their own value.
