Advanced automation technology helps transform the machine tool manufacturing industry
The degree of automation of machine tool products has a crucial impact on the speed and accuracy of machine tools, and has become an important factor in distinguishing machine tool grades. Advanced automation technology and products will undoubtedly become an important direction for the transformation of machine tool manufacturing industry, and its development potential will be highlighted in this change. In machine tool products, especially high-end machine tools, automation technology and products are used in almost every part of the control mechanism, actuators and measurement and feedback mechanisms. At present, almost all kinds of automation products used in machine tools and machine tool production lines In the midst of new changes. As a manufacturing power, China's machine tool industry has been in a high position in recent years. Before the financial turmoil, this high-growth situation has been maintained for seven consecutive years. During this period, the manufacturing volume of Chinese machine tools also rose from the world's ninth to the world's third, and the output value increased nearly six times. The title of "World Factory" undoubtedly means huge market demand. This demand is like a huge thrust. It once pushed the machine tool manufacturing industry to the forefront. It seems that there will never be a stagnant trend. However, the arrival of the turning point is still inevitable. Whether it is the raging and spreading of the financial turmoil or the internal changes in market demand, it has put a severe test on the machine tool manufacturing industry. At this moment, the transformation of the machine tool manufacturing industry is more urgent than ever. The steps of product structure adjustment are started almost simultaneously in various domestic machine tool manufacturing enterprises. Adapting to and responding to market demands as soon as possible under the new situation is the common aspiration of these enterprises. In fact, product structure adjustment is an important part of the transformation of machine tool manufacturing industry, and the degree of automation of machine tool products has become one of the important factors to distinguish machine tool grades. Advanced automation technology and products will undoubtedly become an important direction for the transformation of the machine tool manufacturing industry, which will be a huge pull for the automation product market. And how will the automation market respond to this questionnaire full of opportunities? Policy and demand drive the transformation of machine tool manufacturing It can be seen that after the financial crisis was detonated, the momentum of the machine tool industry has dropped significantly. In reality, however, the market's changes in the demand structure of machine tool products have been subtly occurring before the financial crisis. According to Wu Bolin, Director General of China Machine Tool & Tool Industry Association, from January to September 2008, the machine tool industry increased sales by 32% compared with the same period last year, total output value increased by 31%, and profit increased by 30%. The data still maintains a steady and rapid development, but at the same time it also shows some characteristics. First of all, the sales situation of domestic machine tool products has undergone major changes. In the case of metalworking machines, sales increased by 32% and production increased by only 2%. This shows that the market for low-end, small-size products has declined, while the market for high-end, high-value-added products has increased. On the other hand, from the perspective of import demand, from January to September 2008, the import value of China's machine tool industry has increased significantly, and the number of imports has decreased. Taking a large number of machining centers and CNC lathes as an example, the price of each imported machining center has increased by an average of 13,000 US dollars, and the average numerical control lathe has increased by 90,000 US dollars. This reflects that the demand for foreign high-end machine tools is not falling. . In summary, the domestic low-end machine tools are gradually showing overcapacity. At the same time, domestic enterprises have insufficient production capacity for medium and high-end machine tools, and the trend of demand changes is self-evident. At this moment, the advent of the financial crisis is playing a catalytic role, making the contrast of this situation more obvious. On the one hand, its impact on the manufacturing industry has caused a sharpening of the demand for some low-end machine tools. On the other hand, the series of projects that the country has responded to the financial crisis and expanded the huge investment in domestic demand once again stimulated the demand for high-end machine tools.

ABS plastic,full name acrylonitrile–butadiene–styrene copolymer,
Acrylnitrile butadiene Styrene copolymer has a good thermal and dimensional stability and high impact strength(also at low temperature).It is strong,shows a good scratch resistance and has a good dimensional stability .ABS Plastic can be used in temperatures ranging from -50'C to +70'C .it mainly have ABS SHEET,ESD ABS SHEET,FIREPROOF OF ABS SHEET,ABS+PC SHEET.
Classification:
ABS plastic according to impact strength can be divided into: ultra high impact type, high impact type, medium - resistant type and so on;
ABS plastic can be divided into: injection, extrusion, pressure delay, vacuum and blow molding.
ABS plastic can be divided into: general grade, heat resistance grade, plating grade, flame retardant grade, transparent grade, anti-static, extruding plate and pipe grade, etc.
Advantages:
1.Good mechanical strength, high impact strength
2.Resists scratching, Excellent abrasion resistance
3.Good electrical properties, moisture and creep resistance
3.High dimensional stability, good luster
4.Good chemical and stress cracking resistance to inorganic salt solutions, alkalis and many acids(strong oxidizing acids is a exception).
Disadvantages:
1.Endurance in water ,endurance in corrosion of inorganic salt. But not endurance in organic solvent.
2.ABS Plastic is easily to cracked by the effects of the organic solvent.
3.Poor weather resistance, easily to change color and become brittle because of the sunlight.
Application:
1. Electronics & electric appliances: antenna socket, coil former, wiring board, convertor, speaker,connector, and other parts;
2. Food industry parts;
3. Building model, model mockup;
4. Electronic industrial parts, freezer and refrigeration industry;
Notes:
1. ABS Plastic is strict requirements for flame retardant grade ABS to prevent the decomposition of flame retardants.
In the start of the power, the cartridge should be cleaned with general grade ABS plastic and then processed.
(point to stop for more than 20 minutes before the downtime), on the one hand must cut cylinder temperature below 100 ℃, on the other hand must be emptying the material inside the cylinder, and general level ABS cleaning cylinder rear can stop.
The purpose is to make flame retardant ABS not decomposed.
2. The use of reworked material for primary or secondary sex thousand net, without impurities, no decomposition of ABS plastic reworked material, can be used directly after crushing, also can mix with the new material, the mixing ratio is generally not more than 25% of the new material, so as not to affect performance.
For more than 5 times more than 5 times or adding the fresh material with colorant, generally not mixed with the new material, mainly to prevent the color difference.
ABS Plastic must be dried and processed in accordance with the regulations, whether it be separately regenerated or mixed with new materials.
