CIMT2023 is an internationally renowned exhibition organized in the post-epidemic period. The abrasive products exhibited represent the current highest level in the industry, and we can also see the development trend of abrasive products in the future.
1. Tracking innovation will remain a typical pattern of technological breakthroughs in the industry in the future.
Due to the constraints of various factors, the abrasives and abrasives industry lacks fundamental research and development. In addition, the downstream fields are numerous and complex, and the corresponding grinding application scenarios are different. and there is a lack of culture of originality. The ground for innovation, so at present, the mainstream R&D ideas of most of my country’s abrasives and abrasives enterprises are still based on imitation and follow-up. In recent years, with the accelerated localization of high-end abrasives (mainly ceramic microcrystalline abrasives) and the continuous improvement of processing equipment, domestic abrasive enterprises have fully exploited their late advantages to achieve excellent results in terms of product quality stability and grinding. performance. It has made great progress and has the foundation to further catch up with foreign advanced products. At this exhibition, the key word most often mentioned by enterprises is that their own products have the ability to replace imported products, although the current substitution category is still mainly mid-range products, and the Benefits mainly translate into high costs, but with high costs. the continuous accumulation of materials and processes, it is believed that in the next ten years, domestic high-end abrasive tools will have relatively strong competitiveness.
2. The solution for complex grinding is direction
The innovative development of grinding tools is closely related to the development of high-end machine tools. In recent years, with the decline in the price of super-hard abrasives, the comparative advantage of ordinary abrasives in the low-end market is gradually decreasing, which means that companies need to find new growth points from the perspective of Current market demand, complex grinding. solutions This must be the key direction for the development of grinding enterprises in the future. Complex grinding requires higher machining precision, faster grinding efficiency and more optimized grinding process. The solution means that the company must move from “manufacturing” to “service”, which is also a test for the company’s overall R&D and manufacturing capabilities. an essential requirement for collaborative innovation and development of the industrial chain. Judging from this exhibition, some enterprises have realized the importance of deep industrial chain integration for future development, and have taken the initiative to go deep downstream and jointly carry out research and development. developments, which is very conducive to solving the “stuck neck”. ” problem of my country’s manufacturing industry, and also provides enterprises with a deep-rooted ecological niche in the high-end industrial chain leading the way.
3. Green development extends to the entire product life cycle
Since General Secretary Xi announced China’s “double carbon” goal in 2019, the concept of green development in industry has reached a new stage. In the past, companies focused on the eco-friendliness of products and environmental protection measures in the production process. With the adjustment of national policies, enterprises now need to analyze the needs of a product, design it, manufacture it, sell it, use it, repair it, scrap it and dispose of it. recycle it. From the entire life cycle, readjust its own green level. Judging from this exhibition, some international companies have already put forward the concept of sustainable production, emphasizing that through technology upgrades, material upgrades, equipment improvements, etc., they will ensure that they achieve zero carbon emissions throughout the life cycle of their products in 2035. This is also the case for domestic factories. This is one of the key questions tooling companies need to consider in their planning and R&D over the next ten years.
