1) Use anchor screws and protective layer pads to fine-tune the level of the machine tool's plate-type bed. After leveling, move the columns, slides, and operating table on the machine tool to observe the horizontal changes of the machine tool within the full schedule of each coordinate arrangement, and accordingly adjust the geometric accuracy of the machine tool to keep it within dimensional tolerance ranges. When adjusting, the key is to focus on adjusting the shim; when necessary, you can slightly modify the inserts on the guide rails and the torque rollers.
2) Adjust the relative positions of the robotic arm, spindle bearings, and CNC tools. The hand-pulled method allows stepwise interchange of CNC tool postures, checking whether the gripping, loading, and extraction postures are precise and appropriate. During adjustment, calibration and inspection are used; if there is an error, the robotic arm's schedule can be adjusted or the robotic arm support or CNC tool positions can be moved. 3) For machines with APC interchangeable operation tables, the control table should be moved and adjusted to the interchangeable position, adjusting the relative position between the tray edge and the interchangeable kitchen countertop, ensuring a stable, reliable, and appropriate posture during automatic switching. Next, place 70%~80% of the allowable load on the kitchen countertop, perform multiple automatic interchangeable positions, and tighten all relevant screws after ensuring proper accuracy.
4) Carefully and thoroughly check whether the main control parameters in the CNC system and PLC equipment comply with the specified data information in the raw materials, then test the functions of each key operation process, safety management measures, and the implementation of common commands. For example, various movement modes (hand-pulled, running, automatic, etc.), spindle bearing gear shift commands, and whether each transmission ratio command is properly accurate.
