CNC Boring, Milling Machine And Machining Center Processing Technology

The common feature of the three-coordinate CNC boring and milling machine and the machining center is that in addition to the technological performance of ordinary milling machines, it also has the ability to process complex two-dimensional and three-dimensional complex contours.  Some of these complex contour parts only need two-axis linkage (such as secondary curve, two-dimensional contour and two-dimensional area processing), and some require three-axis linkage (such as three-dimensional surface processing), and their corresponding processing generally corresponds to It is called two-axis (or 2.5-axis) machining and three-axis machining. 

For the three-coordinate machining center (whether vertical or horizontal), due to its automatic tool change function, it is suitable for multi-process processing, such as boxes and other parts that require multi-process processing such as milling, drilling, reaming and tapping.  Especially on the horizontal machining center, after installing the CNC indexing turntable, it can realize four-side machining, and if the spindle direction can be changed, five-side machining can be realized, so it can complete the machining of more surfaces in one clamping, especially suitable for It is suitable for processing complex boxes, pump bodies, valve bodies, shells and other parts.

Four-coordinate refers to adding a rotation coordinate axis (A or B) on the basis of the three translational coordinate axes of X, Y and Z, and the four axes can generally be linked. Among them, the rotation axis can act on both the tool (tool swing type) and the workpiece (table rotation/swing type); the machine tool can be either vertical or horizontal; in addition, the rotation axis can be either The A axis (rotation around the X axis) can also be the B axis (rotation around the Y axis). It can be seen from this that most of the four-coordinate CNC machine tools/swing structures are used. But no matter which type it is, the common feature is that, relative to the static work, the movement position of the tool is not only controllable arbitrarily, but also the direction of the tool axis can be controlled in the tool swing plane, so that it can be controlled according to the processing object. 

The geometric features of the tool adjust the attitude of the tool relative to the surface of the part according to the needs of maintaining an effective cutting state or avoiding tool interference.  Therefore, four-coordinate machining can obtain a wider process range and better cnc machining effect for three-coordinate machining.
