1. Different principles


3-axis processing by the linear feed axis X, Y, Z processing.


The 5-axis machining consists of linear interpolation motion of the feed axis X, Y, Z and any 5-axis in the rotating axis A, B, and C around X, Y, and Z.


2. Different processing characteristics


3-axis machining: the direction of the cutting tool remains the same as it moves along the whole cutting path. The cutting state of the tip cannot be perfect in real time.


5-axis machining: in the process of moving along the whole path, the direction of the tool can be optimized and the tool can move in a straight line at the same time. In this way, optimum cutting conditions are maintained throughout the path.


Machining center is often divided into vertical machining center and horizontal machining center according to the spindle in the state of space, the spindle of the machining center in the vertical state of space is called vertical machining center, the spindle in the horizontal state of space is called horizontal machining center.


Spindle can be vertical and horizontal conversion, known as vertical horizontal machining center or five processing center, also known as the composite machining center. According to the number of processing center columns; There are single column and double column (gantry).


According to the machining center movement coordinate number and coordinate number of simultaneous control: there are three axis two linkage, three axis three linkage, four axis three linkage, five axis four linkage, six axis five linkage and so on. Three axis, four axis refers to the machining center with the number of moving coordinates, linkage refers to the control system can control the number of moving coordinates, so as to achieve the tool relative to the workpiece position and speed control.


According to the number and function of the worktable: there are single worktable machining center, double worktable machining center, and multi worktable machining center.


According to the machining accuracy: there are ordinary machining center and high precision machining center. The general processing center has a resolution of 1 × m, a maximum feed speed of 15 ~ 25m/min, and a positioning accuracy of about l0 × m. The high precision machining center has a resolution of 0.1μm, a maximum feed speed of 15 ~ 100m/min, and a positioning accuracy of about 2μm. Between 2 ~ l0 micrometers, ±5 micrometers, can be called precision level.
