The development of China's high-end CNC vertical lathe machine tools has made great progress in recent years. The breaking of many intermediate technologies has enhanced the competitiveness of China's machine tool industry in international shopping malls. However, it cannot be denied that there is still a large gap between the domestic machine tool work and the international leading level.
Some key technologies, such as: high-speed and high-precision motion control technology, dynamic summary compensation technology, multi-axis linkage and composite machining technology, intelligent technology, high-precision direct-drive technology, reliability technology, etc. need to be further broken, and some serious technologies are still out of industrialization. There is a journey. The technical problems that urgently need to be disposed of are the following:
(1) Improve product reliability. Reliability is the guarantee of forward product quality and production power. At present, the research and development of domestic CNC machine tools are mainly oriented to high-grade, seeking high-speed, precision and multi-axis linkage machining. Although many products have reached or even crossed the ranks of international companies with best-in-class products in terms of functions and specifications, the stability and reliability of the products are still relatively poor. With the increase of complex functions and the introduction of intensive technology, the risk of unreliable factors and disadvantages has increased, making the market share of the shopping malls low and competitiveness weaker. The reliability of CNC machine tools involves the description, testing, manufacturing, installation, supply, and after-sales service of the production plant. It involves suppliers of accessory parts and external parts, and also relates to machine tool users. This is a There is a need for multiple system projects that work together somewhat. Even the entire company needs to improve the reliability of the product, to dispose of the product's seemingly insubstantial doubts, and to enhance the overall market competitiveness of the product.
(2) Heavy-duty numerical control machine tools are upgraded on the top and the bottom level, and several key common technologies are to be disposed of critically: complete machine description techniques; representative motion reliability descriptions; reliability addition and addition test techniques; high-speed spindle dynamic stiffness and bearing thermal balance System and dynamic balance research; high-speed feed dynamic characteristics inspection, forward-looking control, speeding up smooth control technology; automatic on-line measurement, fault compensation technology; long stroke without open space transmission technology and other technical questions.
(3) The working speed and accuracy of the forward intermediate transmission components, as well as the manufacturing technology level and quality of the entire machine tool. Through increasing research and development efforts, optimizing technical methods, strengthening scientific research and testing, upgrading information methods, and accelerating improvement and promotion of other methods, advance the manufacturing level and quality of CNC machine tools.
(4) Establish an R&D system that combines the company as the main body, the shopping mall as the orientation, and the combination of production, study, and research, and move forward with independent innovation. We must solidly promote industrialized base projects; collaborate with universities, promote production with leading technologies, apply academic theories to stabilize academic theories, promote technological innovation through academic theories, and foster strong technical teams; Resilience and possession.
Leisure chairs are a type of furniture used for rest, relaxation, and enjoyment, typically with comfortable seat and backrest designs to provide optimal comfort and support. There are a wide variety of leisure chairs that can be classified based on different functions, materials, styles, and uses. The following will introduce several common categories of leisure chairs.
1. Classification by function:
-Lying chair: Lying chair is a leisure chair that can adjust its angle to meet different needs, and can be used for lying, reading, resting, or sunbathing.
-Lazy chair: Lazy chair is a large and comfortable leisure chair, usually with a wide seat and backrest, which allows people to sit or lie comfortably.
-Leisure sofa: A leisure sofa is a leisure chair with multiple seats that can be used by multiple people at the same time and is usually used for family entertainment or leisure activities.
2. Classification by style:
-Modern style chairs: Modern style chairs usually adopt simple lines and modern design, with fashionable and minimalist characteristics, suitable for modern home decoration.
-Classical style chairs: Classical style chairs usually adopt retro designs and exquisite carvings, with elegant and luxurious characteristics, suitable for classical style home decoration.
-Nordic style chairs: Nordic style chairs usually adopt a simple and natural design, emphasizing practicality and comfort, suitable for Nordic style home decoration.
3. Classification by purpose:
-Indoor leisure chairs: Indoor leisure chairs are suitable for indoor environments such as homes and offices, and can be used for activities such as rest, reading, and watching TV.
-Outdoor leisure chairs: Outdoor leisure chairs are suitable for outdoor environments such as gardens, balconies, terraces, etc., and can be used for outdoor leisure, sun exposure, and other activities.
In short, leisure chairs are multifunctional and diverse furniture that can be chosen according to different needs and preferences. Whether relaxing at home or enjoying the sunshine outdoors, you can find suitable leisure chairs for yourself.
