What do you mean by six axis and four linkage?
In CNC machines, multi axis linkage is used to process complex or high precision surfaces or workpiecesThe so-called multi axis refers to multiple axes on one machine (including the linear coordinate and rotating coordinate) on processed at the same time, but also in the computer numerical control system (CNC) under the control of the coordinated motion. Multi axis machining can improve the machining accuracy, surface quality and efficiency of free space. NC machining is of high speed, high precision, high intelligence, high flexibility, high automation and high reliability direction, and multi axis NC machine tool is a reflection of this.
Is the tool x, y, Z can move, and then there is a tool, the direction can rotate is the 4 axis, and then there are two directions to rotate, that is, the 5 axis. And then there are two directions to rotate, that is, the 5 axis. The three directions can be rotated, that is, the 6 axisFour moving lower programming requirements, in the processing of certain parts of the workpiece, which use only 4 degrees of freedom, the other two fixed, can simplify the programming requirements. Such as fixed distance and the axial rotary tool spindle machining, a knife, and then use a fixed two parameters processing under the knife in order to complete a process, such as the workpiece surface.
Six four axis is six axes, four degrees of freedom processing method. The three axis is x, y, Z, the remaining axis refers to the X, y, Z axis rotating reference, how much to achieve function is a few axes. The simple argument is that, each corresponding to a shaft a servo motor, multi axis linkage is the motor can work at the same time, the multidimensional space cooperation processing complex.
