The present situation and advantages of five-axis linkage machining center

Current situation of the development of

Five-axis linkage CNC machine tools abroad is in order to meet the polyhedron and curved surface parts processing. With the new development of composite machine tool technology, on the basis of the numerical control lathe, and can quickly produce the milling and milling center. Five-axis linkage CNC machine machining efficiency is equivalent to two sets of three axis machine tool, sometimes even can completely eliminate some large investment of automatic production lines, greatly saves space and work flow between different manufacturing unit transportation time and costs. The demand of the market to promote the development of five-axis linkage CNC machine tools in China, domestic CIMT99 exhibition five-axis linkage CNC machine for the first time on stage machine tool market. Since multiple CNC machine tool co., LTD in jiangsu exhibition since five-axis linkage gantry machining center, the first Beijing machinery research institute, Beijing first machine tool plant, guilin machine tool co., LTD., jinan second machine tool group co., LTD., and other enterprises also successively developed a five-axis linkage CNC machine tools.

At present, the domestic five-axis linkage CNC machine tools on the varieties have vertical and horizontal machining center, gantry type and floor type, adapted to different size of miscellaneous parts processing, and of five-axis linkage milling and boring and milling machine and milling center, the development of basic covers the domestic market demand. Machine tool accuracy, Beijing institute of high-precision machining center, ning river machinery group co., LTD NJ25HMC40 machine horizontal machining center and jiaotong university kunming technology co., LTD TH61160 horizontal boring and milling machining center with high precision, equivalent to that of the products of developed countries. In product sales, jiangsu multi, jinan second machine tool, electromechanical institute, Beijing ning river, guilin machine tool machine, a machine tool companies such as Beijing has won the recognition of the domestic market.

The morning of July 31, 2013 dalian cape made five axis vertical machine, high-precision Germany shipment of exports. Deputy director general of ministry of equipment department Wang Weiming said: "this high-end CNC machine tools in the western developed countries, is an important milestone in China machine tool manufacturing industry."

advantage

It is generally believed that, five-axis linkage CNC machine tool system is to solve the impeller, vane, Marine propeller, heavy generator rotor, turbine rotor, the only means of large diesel engine crankshaft, and so on processing. It is a high technology content, high precision special machine tool for machining complex curved surface, the machine tool system of a country's aviation, aerospace, military, scientific research, precision instruments, high precision and so on the medical device industry is of vital significance.

The use of five-axis linkage machine tool, it easy to let the workpiece clamping. Processing without special fixture, reduce the cost of the jig, avoids repeatedly clamping, improve the machining precision of the die. Adopts the technology of the five-axis processing mould can reduce the amount of using jig. In addition, because of five-axis linkage machine can save many special cutting tool in machining, so reduce the tooling cost. Five-axis linkage machine tool that can increase effective cutting edge length of cutting tool in machining, reduce the cutting force, improve the service life of cutting tools, reduce the cost. The five-axis linkage machining mold can quickly complete the mould processing, delivery fast, better guarantee the quality of the mould, make it easier to mold processing, and makes it easy to mould modification. In the traditional mould processing, generally with vertical milling machining center to complete the workpiece. With the continuous development of mould manufacturing technology, vertical machining center itself is showing obvious weaknesses. Modern mold processing generally use ball head milling cutter for machining the ball milling cutter head in mould processing benefit is very obvious, but if use vertical machining center, the bottom of the linear velocity is zero, so bottom surface degree of finish is very poor, if you use four, five-axis linkage machining technology in mold processing, can overcome the above shortcomings.
