How to distinguish three-axis machining center, four-axis machining center and five-axis machining center? +
To understand what a three-axis machining center, a four-axis machining center, and a five-axis machining center are, we must first understand the six degrees of freedom of an object. The object has six degrees of freedom in space, namely the freedom of movement along the three rectangular axes x, y and z and the freedom of rotation around the three axes A, B and C. It is customary to call the above six independent motions the six degrees of freedom.
Three axis machining center as the name suggests, only three axes are respectively XYZ axis (that is, only open movement degrees of freedom X, Y, Z, no open rotation degrees of freedom A, B, C). Three-axis machining center is our common and commonly used machining center, three-axis machining center we usually call it three-axis linkage machining center, it can be three axes with movement at the same time to achieve processing, three-axis machining center price is also cheap processing center inside, there are vertical and horizontal points, vertical three-axis machining center can effectively process only the top surface of the workpiece, Even a horizontal three-axis machining center can only process four surfaces with the help of the rotary function of the table. In daily work, we just simple processing a plane, not to do complex technology, so the three axis is the first choice.
Four axis machining center is x, Y, z axis plus A rotation axis, usually we call a axis, and the fourth axis can not only move alone but also can respectively and another axis or two axis or the four axis at the same time. Generally speaking, it can be understood that adding the fourth axis can make the plane of tool processing more widely, and can reduce the workpiece repeated clamping, improve the overall processing accuracy of the workpiece, which is conducive to simplifying the process and improving production efficiency. The fourth axis is also called the numerical control indexing plate, rotating table. It is used to process different parts of the workpiece from different angles, which effectively improves the machining accuracy and efficiency. Suitable for processing rotating workpiece, turning and milling composite parts.
Five-axis linkage machining center is also called five-axis machining center. It is a kind of machining center with high science and technology content and high precision, specially used for machining complex curved surface. This kind of machining center system has a decisive influence on a country's aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries. Five axis machining center has x,y,z,a,c five axis, xyz and ac axis form five axis linkage processing, good at space surface processing, shaped processing, hollow processing, drilling, oblique hole, oblique cutting. It is the only means to solve the processing of impeller, blade, Marine propeller, heavy generator rotor, turbine rotor, large diesel engine crankshaft and so on.
