Structural Characteristics and Working Principle of Five-Axis Linkage Machining

1. Definition of Five-Axis Linkage Machining: There are at least five coordinates on a machine tool, which are three linear coordinates and two rotary coordinates respectively.

2. Five-axis machining characteristics:

(1) Three-axis machine tools can not be processed or need to be clamped too long

(2) Improving the Accuracy, Quality and Efficiency of Free Space Surfaces

3. The difference between five-axis machining and three-axis machining; the difference between five-axis machining and three-axis multi-two rotating axes, the establishment of five-axis coordinates and the determination of Z-axis code: the determination of the axis direction of machine tool spindle or the vertical direction of worktable clamping workpiece as Z-axis X-axis; the determination of the horizontal plane parallel to the workpiece installation surface or the selection of the direction of the vertical axis of rotation with workpiece in the horizontal plane as X-axis, far as X-axis. The direction away from the axis of the spindle is in the right direction.

4. Linear coordinates X axis Y axis Z axis rotation coordinates A axis, B axis, C axis A axis: rotation around X axis A axis B axis: rotation around Y axis B axis C axis: rotation around Z axis C axis XYZ+A+B, XYZ+A+C, XYZ+B+C three forms of five-axis.

5. Five axes are divided into two categories according to the position relationship of the spindle: horizontal and vertical.

6. The five axes are determined by the relationship between the rotating spindle and the linear motion. The structure of the five axes linkage is as follows:

(1) Double rotary table (A+B for example) superimposes a A-axis rotary table, small turbine, impeller and compact die on the B-axis rotary table.

(2) A+B+C Rigid Precision with One Rotation and One Pendulum

(3) Double pendulum head worktable is large, powerful, suitable for large workpiece processing, gantry type
