In modern industrial production, the production of medium and small batch parts accounts for an increasing proportion of the number of products, and the complexity and precision requirements of parts are rapidly increasing. Traditional ordinary machine tools have become more and more difficult to meet the requirements of modern production, and CNC machine tools With high precision, high efficiency, multi-purpose, it can complete the characteristics of complex surface processing, especially the rapid development of computer technology and widely used in CNC systems. The main functions of numerical control devices are almost entirely realized by software. Universal, making it more flexible and more powerful. The competition in the manufacturing industry has reduced the labor cost, product cost, the overall efficiency and quality of the company, and the competition to fully meet customer requirements and actively develop new products will face knowledge-technology-products. The update cycle is getting shorter and shorter, the product batch is getting smaller and smaller, and the quality and performance requirements are higher. At the same time, the society's awareness of environmental protection and green manufacturing is continuously strengthened. Therefore, agile and advanced manufacturing technology will become the main means for enterprises to win competition and survive and develop. The combination of computer information technology and manufacturing automation technology is becoming more and more close, and the proportion of CNC machine tools, which are an important basis for automated flexible production, will increase in production machines. Second, the status quo of CNC flat grinding and the main CNC system The surface grinder adopts the numerical control system relatively late than the lathe, milling machine, etc. because of its special requirements for the numerical control system. In the past ten years, with the help of CNC technology, the continuous dressing of the grinding wheel on the grinding machine, automatic compensation, automatic exchange of grinding wheels, multiple worktables, automatic transfer and clamping of workpieces and other operational functions have been realized, and numerical control technology has been gradually popularized on surface grinders. In recent years, Hannover, Tokyo, Chicago, and domestic large-scale machine tool exhibitions, CNC grinding machines have occupied the majority of the entire grinding machine exhibits, such as Germany BLOHM company, ELB company and other famous grinding machine manufacturers no longer produce ordinary grinding machines, Japan's Ben, Rixing and other companies have also produced full-function CNC flat grinding in batches. While developing high-grade CNC flat grinding, they are actively developing medium and low-grade CNC flat grinding. In the past few years, the BRILLIANT series two-axis CNC forming grinding machine produced by ELB Company of Germany has the vertical and horizontal axes as the numerical control axis and the vertical direction as the hydraulic control. The grinding wheel is finished with the diamond roller mounted on the worktable, which has a wide application range; SUPER-BRILLIANT series It is a three-coordinate CNC plane and a forming grinder. The bed is made of natural granite. The geometric precision is extremely high. The guide rails are linear rolling guides. The mechanical drive has no backlash, thus ensuring a good surface finish of the workpiece. BRILLIANT-FUTURE is the above two. A series of improved products, the bed is made of artificial granite, the longitudinal pressure rail is used, the toothed belt is driven, the vertical and horizontal rails are preloaded linear rolling guide, ball screw drive, three-axis CNC control AC servo motor, 0.5 Measurement resolution of μm. At the same time, ELB has developed the latest state-of-the-art grinder products, namely the CAM-MASTER series of flexible grinding units based on mechatronics and computer technology, the CAD-MASTER series and the COMPACT-MASTER series of grinding centers, with the most control axes. It can reach 24 axes. In addition, due to the full implementation of modular design, the manufacturing cycle of special grinding machines is shortened. ELB has also developed a variety of high-efficiency special grinding machines, such as SFVG100/2 special grinding machines, with tiltable grinding heads, continuous dressing, and slow-feeding. , oblique cutting into the grinding function, with 11 CNC control shaft, such as the same grinding center. UK JONES%26amp; SHIPMAN company and American AB company developed A-B8600 numerical control system for FORMAT5 type CNC flat grinding, CNC controlled hydraulic valve, driving longitudinal adjustable speed movement, horizontal and grinding head feeding ball screw pair , DC servo motor drive, intermittent wheel dressing, CRT graphic simulation display. At the same time, other types of CNC systems can be used to meet the requirements of different users. Next page One-hole Basin Faucets are much more user-friendly than the rest basin faucets. Installation is simple and requires the drilling of only one hole.
