CPC Central Committee and State Council on the revitalization of northeast old industrial base initiatives, like the spring breeze blew through the Northeast earth. Total investment of 61 billion yuan of treasury bonds of 100 technological transformation projects, beginning the prelude to the Northeast. So in the end these projects need what kind of machine tool equipment?
The most sought after CNC machine tools
High speed, high precision, high efficiency and multi-axis CNC machine tools is the key equipment for the Northeast market needs. The shape of curves and surfaces for complex processing, multi-axis NC machine tools with special functions can not be replaced. Large turbine blades, pump pump wheel, impeller, housing, aviation engine impeller, blade, complex aircraft structural parts, ship propeller, screw compressors, complex shapes need to adopt multi-axis tool CNC machining. Currently, five-axis NC machine tool imports dominate. As technology advances and the development of mechanical and electrical products and equipment category, multi-axis (in particular, more than four-axis linkage) applied more and more CNC machine tools. Among these technology projects, the need to equip a group of five-axis vertical machining center, five-axis vertical-horizontal machining center, five-axis machining center, five-axis CNC grinding machines, five-axis high speed machining center bridge , 5 axis CNC milling machines, etc..
Heavy, super heavy duty and high precision CNC machine tool market demand gradually expanding. Northeast China's heavy-duty, mining, metallurgy, power generation, shipbuilding and petrochemical equipment manufacturing base. The main products are the key pieces of large heavy-weight, and some are overweight, large parts, such as a large rolling mill, roller, large generator base, spindle, marine diesel engine parts, pumps, fans, compressor base, cylinder body large aircraft structural parts, such as heavy-duty machine bed column. Most of the weight of such large parts, complex shapes, high precision, need heavy-duty, super heavy-duty CNC machining. With the military, machine tools and high-tech industry development, increasing demand for high-precision CNC machine tools. Currently, the major technical transformation of enterprises plan to increase the number of the corresponding heavy, super heavy duty and high-precision CNC machine tools.
Efficient, dedicated or specialized machine applications in the ascendant. High efficiency is the eternal pursuit of the manufacturing sector. Private or specialized CNC machine tools in the manufacturing sector will play an increasing role in some special type of machine tool industry is more urgent. Locomotive manufacturing, auto parts manufacturing, air conditioning and refrigeration equipment manufacturing, aerospace equipment manufacturing and so on efficient, dedicated or specialized CNC machine tools with greater needs.
Urgent reform the old equipment
China is the world's manufacturing power, metal cutting equipment has a capacity of 300 million more than the rate of about 2% of NC, NC transform the old equipment, a huge market. Northeast old industrial base survey found that many large state-owned enterprises, with a lot of metal cutting equipment, but equipment are quite serious, NC equipment was still very low, most of the CNC Equipment 2% to 4%, and some machine tool enterprises, NC rate of less than 5%. Some sectors have heavy, super heavy-duty machine tool more, but outdated equipment can not meet the production demands, NC transformation needed.
In the research discovered that some companies in the Numerical Control Transformation of large equipment has achieved good results. Military enterprises such as Shenyang, a large-scale import of the three milling machine, control system update, restore performance, good results. Shenyang Pump Co., Ltd. made on a CNC lathe landing problems and defects are modified and have achieved good results.
Experts believe that the transformation of the old equipment should first conduct a feasibility analysis: For the mechanical structure behind the ordinary equipment accuracy has been lost, we should not reform; to maintain good mechanical properties and the accuracy of the control system behind the machine, should be carefully studied in what grade of NC system reform; for early NC machine tool factory, due to numerical control systems and components have been behind some of the features, but also the possibility of transformation; for heavy-duty, precision machine tools, should be cautious, be tested, to take practical feasible reform program.
The user to reflect, to improve production level and production efficiency, production line in large-scale use of general machine tools, NC urgent reform. CNC machine tool demand in China has started from the economic mainstream shifted popular type, mainly due to universal application of NC machine tools have been more mature, using the wide, good cost performance. In this research, the part of universal type CNC lathes, CNC milling, medium-sized machining centers, grinding machines, electric machines have very large market. Yong Hu technological transformation mainstream equipment. Aviation, aerospace, military enterprises, universal CNC machine tools is also a large proportion. I am an expert from China Agriculture Net, usually analyzes all kind of industries situation, such as mango pulp , hardware distributor.
