4. Three-axis linkage CNC system realizes the machining of parts milling
Modification using a three-axis linkage or a two-axis half (three-coordinate any two-two linkage) CNC system can make the programming easier and better. The CNC modification of the CA6140 horizontal lathe is the same as above. In the numerical control transformation, the X-direction stepping motor is used to control the lateral feed motion of the lathe, the Z-direction stepping motor is used to control the longitudinal feed movement of the lathe, and the Y-direction stepping motor is controlled by the FW160 universal indexing head to drive the lathe spindle VI (with the moving wire). Rotary motion of the bar workpiece). The difference between this and the ordinary CNC machining is that the Y is moved to the original straight line in the numerical control system, subtly changing to the rotating operation of the workpiece, and the running displacement length of the workpiece rotating one time is constant L y = 5 × 40 = 200 (mm) . Other CNC machining, the same as the aforementioned control.
Practice has proved that the numerical control transformation of the horizontal lathe is carried out under the premise of expanding the numerical control milling processing function, while avoiding the conditional limitation of the lack of high-grade numerical control system in the general unit, and the two sets of economical numerical control systems are skillfully connected in series (generally The unit can be equipped with), which realizes multi-axis linkage control, broadens and expands the application range of CNC lathes, and therefore has strong practicability.
