With the continuous development of the world's advanced manufacturing technology, the application of ultra-high speed pressing and ultra precision machining technology, the rapid development of flexible manufacturing system and the continuous maturity of computer integrated system, higher requirements for processing technology are put forward. Nowadays, the hydraulic press industry will develop to the following trend.
High speed and high precision. Speed and precision are two important indexes of CNC machine tools. It is directly related to the processing efficiency and product quality. At present, the numerical control system uses the digits and the higher frequency processor to improve the basic computing speed of the system. At the same time, the super large scale integrated circuit and multi microprocessor structure are adopted to improve the data processing ability of the system, that is to improve the speed and accuracy of interpolation operation. Linear motor directly drives the linear servo feed mode of the machine tool worktable, and its high speed and dynamic response characteristics are quite superior. With feedforward control technology, the tracking lag error is greatly reduced and the processing precision of corner suppression is improved.
Affected by the global macroeconomic downturn, the growth of machine tool consumption in the world is still relatively slow. In 2014, the global consumption of machine tools was about US $58 billion 10 million, and the consumption volume decreased from 2012 to 2013. In recent years, China's manufacturing industry continues to slump, machine tool consumption is affected, but it is still the first place in the global machine tool consumption. It accounted for 20% in 2014, followed by the US and Germany, accounting for 16% and 14% respectively.
After 2011, the growth rate of China's macro-economy has fallen down, and the macro economy has shifted from the high speed growth period to the medium and low speed growth period. In the first half of 2015, China's macro-economy is still running at a low level. The downward pressure is still large. The signs of stabilization and recovery are still not clear. The machinery industry is still in the stage of adjustment and upgrading of economic development. The machine tool industry is greatly influenced by the macro economy, and its demand will gradually rise and enter the period of low speed growth.
The machine tool industry is the basic equipment industry of an economy. Its technology level and product quality are important signs to measure the comprehensive strength of the economy and the development level of the equipment manufacturing industry. In addition, according to the key areas of key technology breakthrough to realize industrialization, the state will improve the marketing policy, play the guiding role of government procurement on the market; innovation of central government funding arrangements, the central budget for investment as a guide, to attract social capital into the advanced manufacturing industry, and gradually expand the scale of investment funds, fostering innovation and development the backbone of the enterprise and industry alliances, the integration of industrial chain resources, promote the sharing of benefits and risks.
