Machining centers are commonly used equipment in industrial applications for processing metal parts. Generally, a swing table is set on the processing table, and metal parts are placed on the swing table for processing. During the processing, the processing table moves along the guide rail to process the metal parts into the desired shape.
In the process of using the machining center, try to complete all the processing content in one clamping. When it is necessary to replace the clamping point, pay special attention not to damage the positioning accuracy due to the replacement of the clamping point, and specify it in the process file if necessary. For the contact between the bottom surface of the fixture and the worktable, the flatness of the bottom surface of the fixture must be within 0.01-0.02mm, and the surface roughness should not be greater than Ra3.2um.
Which parts should be maintained when using a machining center? Let’s take a look together below.
1. Check the safety devices of the CNC vertical lathe.
(1) All limit switches, indicator lights, signals, and safety protection devices are complete and reliable.
(2) The electrical installations are well insulated, the installation is reliable and grounded, and the lighting is safe.
2. Check and adjust the iron filings, pressing plates, gaps, fixing screws, nuts, and handles of various parts, which are flexible and easy to use.
(1) The gap between the inclined iron, pressing plate, and sliding surface of each part is adjusted to within 0.04mm, and the moving parts can move freely.
(2) There is no looseness or missing of fixing screws and nuts in various parts.
3. Cleaning, dredging, lubricating and cooling system, pipelines, including oil holes, oil cups, oil lines, and felt filter devices.
(1) The oil window is clear and bright, the oil mark is eye-catching, the oil is in place, and the oil quality meets the requirements.
(2) The inside and outside of the oil tank, oil pool, and filter device are clean, free of dirt and impurities.
(3) It is necessary to ensure that the oil line of the CNC machining center is complete, the linoleum is not aging, the lubricating oil path is unblocked, and there is no oil or water leakage.
(4) The oil gun and oil can are clean and easy to use, the oil nozzle and oil cup are complete, and the hand pump and oil pump are easy to use.
