In recent years, China's CNC machine tool industry has vigorously promoted the application of CAD and other information technologies. Many enterprises have begun and plan to implement ERP, MRPII and e-commerce. For example, Jinan Second Machine Tool Group Co., Ltd. has a CAD penetration rate of 100%. It is a national “CAD demonstration enterpriseâ€. The application of the enterprise's MRPII system is also very successful, and the modern management level is relatively high.
There are three shortcomings
However, compared with developed countries, China's CNC machine tool industry still has many shortcomings in the application of information technology.
First, the information technology foundation is weak, and the dependence on foreign technology is high. China's CNC machine tool industry has a weak technical development capability and technical foundation, and the application of information technology is not high. The existing sources of information technology in the industry mainly rely on the introduction of foreign technology, and the dependence on foreign technology is high. The digestion of imported technology still remains in mastering the existing technology and increasing the localization rate, and has not risen to the ability to form independent development of products. And the height of technological innovation capabilities. High-performance CNC machine tools with high precision, high speed, high efficiency, composite function, multi-axis linkage, etc. basically have to rely on imports.
Second, the product maturity is low, and the feasibility is not high. The average time-to-failure time of foreign CNC systems is more than 10,000 hours. The CNC system developed independently in China is only 3000-5000 hours; the average trouble-free working time of the whole machine is more than 800 hours abroad, and the best in China is only 300 hours.
Third, the ability to innovate is low and the market competitiveness is not strong. Although there are more than 100 enterprises producing CNC machine tools in China, most of them fail to form scale production, the use of information technology is insufficient, the innovation ability is low, the manufacturing cost is high, and the product market competitiveness is not strong.
Precipitated Calcium Carbonate
Uses: Can be used as filler in rubber, plastics, paper, paint and ink industries. Widely used in organic synthesis, metallurgy, glass and asbestos production. It can also be used as a medium seeding agent for industrial waste water, a antacid for stomach and duodenal ulcers, a detoxifying agent for acidosis, a SOâ‚‚ eliminating agent in SOâ‚‚-containing exhaust gas, a dairy cattle feed additive and an anti-sticking agent for oil felt . It can also be used as a raw material for tooth powder, toothpaste and other cosmetics.
Usually used as a filler, widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc., as a filler to increase products The volume is reduced, and the production cost is reduced.
Light Calcium Carbonate is made of limestone, and can be used in daily chemical products such as tooth powder, toothpaste, cosmetics, etc. It can also be used in organic synthesis, metallurgy, glass and asbestos production.
The particle size of light calcium is smaller than that of Heavy Calcium Carbonate, the oil absorption is larger than that of heavy calcium carbonate, and the price is higher than that of heavy calcium carbonate. They are all commonly used fillers in latex paint, and they are best used together. Light calcium is better in terms of sedimentation, but its oil absorption is greater than that of heavy calcium, and the price is generally more expensive than heavy calcium. Although it is not as stable as heavy calcium, it is stable. Even for exterior wall paint, its application amount is also very large. of.
