CNC machining skills: CNC machine tool installation and debugging of the work first depends on the new CNC machine tool is a small machine tool or a large machine tool. Generally, the installation of small CNC machine tools is relatively simple, while the transportation and packaging of large CNC machine tools must be considered. Therefore, the whole machine tool has to be divided into several parts. After arriving at the work site, it must be reassembled and carefully adjusted. The workload is large and complex. Comparatively speaking, small CNC machine tools can avoid the workload of reorganization after decomposition. However, the open box acceptance and start-up debugging of small CNC machine tools must also be treated seriously and carefully to avoid mistakes and losses. Usually, the debugging of CNC machine tools must go through the following steps.
(1) At the beginning, we did it on the spot. Before the arrival of the machine tool, the installation foundation of the machine tool shall be laid according to the foundation drawing provided by the machine tool factory, and the preset holes of the anchor bolts shall be reserved; the spare parts, accessories, data and accessories shall be counted according to the packing list; the attached documents shall be kept by a special person (especially the detailed list of the parameter setting of the numerical control machine tool, etc.); According to the instructions, all parts of the machine tool must be in place on the site, and all fasteners must be in place according to the number.
(2) Connection of machine tool. Before the assembly of all parts of the machine tool, remove the antirust coating on the installation connection surface, the guide rail and the surface of all moving parts, and do a good job in cleaning the appearance of all parts. Then assemble all parts of the machine into a whole machine, such as installing the column, numerical control cabinet and electrical cabinet on the bed, installing the manipulator of the tool magazine on the column, and installing the extension body on the bed. The original positioning pin, positioning block and positioning element should be used during assembly to restore the installation position to the state before disassembly of the machine tool, so as to facilitate the next step of precision debugging. After the components are assembled, the cables, oil pipes and gas pipes are connected. There are electrical wiring diagram and pneumatic and hydraulic pipeline diagram in the manual of the machine tool, so the relevant cables and pipelines should be connected one by one according to the marks. When connecting, pay special attention to cleaning, reliable contact and sealing, and check for looseness and damage. After the cable is inserted, the screw must be tightened to ensure reliable contact. In the connection of oil pipe and gas pipe, it is necessary to prevent foreign matters from entering the pipe from the interface, so as to avoid the failure of the whole hydraulic system. When connecting pipelines, each joint should be tightened. Otherwise, during the test run, especially on some large oil separators, if one pipe leaks oil, it is often necessary to remove a batch of pipes, resulting in heavy repair work. After the cable and oil pipe are connected, the pipelines shall be fixed in place, the protective cover shall be installed, and the neat appearance shall be ensured.
(3) The connection and adjustment of CNC system includes open box inspection, external cable connection, power connection, confirmation of setting, confirmation of input current, voltage, frequency and phase sequence, confirmation of machine parameters, etc.
(4) Power on test run.
(5) Machine tool precision and function debugging.
(6) Commissioning.
(7) Organize machine tool acceptance
