There are many types of horizontal machining centers with movable columns. There are three types, all of which are movable columns. The workbench is fixed, the column moves in the X direction, the headstock is hung on the side to move in the Z and Y directions; the workbench is moved in the Z direction, the column is moved in the X direction, and the headstock is moved in the Y direction; the workbench is moved in the X direction, and the column is moved in the Z direction Movement, the spindle box moves in the Y direction; these three types are the moving column horizontal machining center. The movable column horizontal machining center has high rigidity, large load capacity, and is suitable for heavy cutting and rough machining. There are three types of horizontal machining centers with fixed columns. The column is fixed, the spindle box moves in Y direction, the workbench moves in Z and X directions, the spindle box moves in Y and Z directions, and the workbench moves in X direction. Kind; the spindle box moves in the Y and X directions, and the work table moves in the Z direction; this is the fixed column horizontal machining center, the horizontal machining center of this type of structure has good structural rigidity, high machining accuracy, and installation adjustment Convenience and other features.
Check the wiring of the power supply transformer of the test element, find that the wiring is wrong, reconnect it. The horizontal machining center is installed with the power supply module, and the power supply module is normal after power on. For manual operation, some axes cannot run. Check the position module, there is no input. Further inspection, the two axial photoelectric encoders have been damaged. All manual operation is normal after replacement. Then it runs automatically and everything is normal. Through this example, when the maintenance personnel disassemble the components during maintenance, the position of the components and the wiring are marked, and there are detailed records. When installing the components, carefully check the correctness of the wiring.
When choosing a numerical control system, it is necessary to integrate a variety of factors, such as the use environment, workpiece conditions, processing technology, procurement budget, etc. For example, when choosing a three-axis vertical machining mold, you can choose Fanuc0iMD-A or Mitsubishi M70-A. , You can choose Fanuc0iMD-B or Mitsubishi M70-B. It is recommended to choose Siemens 840D or Fanuc31i when choosing the five-axis vertical overtime system. If it is used for teaching, you can choose the five-axis of Huazhong or Guangshu. In occasions where processing requirements are not high and budgets are limited, domestic CNC systems or Taiwan systems can be selected.
