CNC 5-axis machine tool

5-axis machining offers endless possibilities for the size and shape of parts you canefficiently process. The term "5-axis" refers to the number ofdirections in which the cutting tool can move. On a 5-axis machining center,the cutting tool moves on the X, Y, and Z linear axes and rotates on the A andB axes to approach the workpiece from any direction. In other words, you canwork on five faces of a part in a single setting.

Developmentstatus

Foreignfive-axis linkage CNC machine tools have appeared to adapt to the processing ofpolyhedrons and curved parts. With the new development of the compoundtechnology of machine tools, on the basis of CNC lathes, a turning and millingcenter capable of milling is soon produced. The processing efficiency offive-axis linkage CNC machine tools is equivalent to two three-axis machinetools, and sometimes it can even completely eliminate the investment of somelarge-scale automated production lines, which greatly saves floor space andfive-axis linkage revolving transportation working between differentmanufacturing units. Time and cost. Advantage

Itis generally believed that the five-axis linkage CNC machine tool system is theonly means to solve the processing of impellers, blades, marine propellers,heavy generator rotors, steam turbine rotors, large diesel engine crankshaftsand so on. It is a high-tech and high-precision machine tool specially used forprocessing complex curved surfaces. The machine tool system has a significantinfluence on the aviation, aerospace, military, scientific research, precisionequipment, high-precision medical equipment and other industries of a country.

1.The first is the use of linear motor drive technology. After more than tenyears of development, linear motor technology has become very mature. Theproblems of susceptibility to interference and high heat generation that havejust been developed for linear motors have been solved. The positioningtechnology of linear motors not only stops quickly at high speeds, but alsosome machine tool manufacturers use damping technology to solve them. Theadvantages of linear motors are linear drive, no transmission chain, no wearand no backlash, so it can achieve the best positioning accuracy. Linear motorshave high dynamics, and acceleration can exceed 2g. The linear motor drive isalso featured by high reliability and maintenance-free.

2,followed by the use of dual drive technology. For the wide table or gantrytype, if the middle drive is used, the driving force cannot be guaranteed inthe center, which will easily cause tilt and make the dynamic performanceworse. The use of dual drives, dual encoders, and one drive module can make thedynamic performance perfect. One drive command, the dual drives work at thesame time, and the grating ruler detects whether the two points are balanced.If they are not balanced, they are balanced by different commands. Of course,the development of five-axis linkage machine tool technology is far more thanthat, many technologies will be reflected in future machine tool products.
