CNC milling machine assembly method.

一, The installation of CNC milling machine:

The general CNC milling machine is a mechatronics design. It is shipped from the manufacturer to the user, and is shipped in the whole machine without disassembly. Therefore, after receiving the machine tool, the user only needs to follow the instructions. Pay attention to the following aspects:

1. Unpacking: After the machine is unpacked, first find the random technical documents according to the packaging mark, and check the attachments, tools, spare parts, etc. according to the packing list in the technical documents. If the physical object in the box does not match the packing list, you should contact the manufacturer in time. Then, read the instructions carefully and follow the instructions to proceed with the installation.

2. Lifting: According to the lifting diagram in the manual, put a wooden block or thick cloth in the appropriate position to prevent the steel wire rope from damaging the paint and the processing surface. During the lifting process, the center of gravity of the machine tool should be minimized. If the electric turtle of the CNC machine is separated, the top of the cabinet usually has a lifting ring for lifting.

3. Adjustment: For CNC milling machine, the main machine is shipped from the whole machine. It is adjusted before leaving the factory. Users should pay attention to the installation: oil pressure adjustment, automatic lubrication adjustment and key inspection to prevent the vertical sliding device of the lifting platform from functioning. Wait.

二, The CNC milling machine debugging and acceptance: For the general CNC milling machine, the host is shipped the whole machine, has been adjusted before leaving the factory. However, users should pay attention to the following points before use: CNC milling machine debugging:

1. Adjustment of oil pressure: Because hydraulic shifting, hydraulic tension and other mechanisms require appropriate pressure, after the machine is unpacked, the oil seal for rust prevention is removed, that is, oil is poured into the oil pool, and the oil pump is turned on to adjust the oil pressure. The pressure of 1-2 Pa can be.

2, automatic lubrication adjustment:

CNC milling machines mostly use automatic timing quantitative lubrication station for oil supply, check whether the lubricating oil pump starts at the specified time before driving. These time adjustments are typically made by relays. It is important to check whether the vertical sliding device of the lifting platform is protected. The inspection method is very simple. When the machine is powered on, fix the table to the bed, use the dial gauge to point to the work surface, then suddenly power off the workbench, and observe whether the work surface sinks through the dial gauge. 0. 01—0. 02mm is allowed, too much slip will affect the consistency of batch processing parts. At this point, the self-locking adjustment can be adjusted.

3. Acceptance of CNC milling machine: For the acceptance of CNC milling machine, it is mainly based on the professional standards promulgated by the state. There are two kinds of ZBJ54014-88 and ZBnJ54015-88. Before the machine tool leaves the factory, it has been inspected according to the above two standards in the factory. The product qualification instructions issued by the quality inspection department, the user can follow the items in the qualified instructions, according to the actual detection methods of the unit, random inspection or all re-inspection Item accuracy, if there are unqualified items, can make representations to the manufacturer. If the re-inspection data meets the requirements of the factory certificate, it can be recorded in the file for future reference.

三, The use conditions of CNC milling machine:

Compared with the machining center, the CNC milling machine is similar to the machining center except for the lack of automatic tool change function and tool magazine. It can drill, expand, ream, boring, boring and tapping the workpiece, but it is mainly Used to mill the workpiece. Generally, the following machining contents are often used for CNC milling: within the contour of the workpiece, the shape, especially the contours such as non-circular curves and list curves given by mathematical expressions. Give the spatial curve of the mathematical model. Complex shapes, large sizes, and areas where scribing and detection are difficult. It is difficult to observe when machining with a universal milling machine, measuring and controlling the inner and outer grooves of the feed. High-precision holes and faces that are coordinated in size. A simple surface or shape that can be milled together in one installation. The use of CNC milling can double productivity and greatly reduce the general processing content of manual labor. The following processing contents are not suitable for rough machining where CNC milling requires long-term manual adjustment. A portion of the blank where the machining allowance is insufficient or not stable. The processing contents must be coordinated according to special tooling, such as standard samples, coordination plates, and mold tires. Simple roughing surface. The part that needs to be machined with an elongated milling cutter, such as a narrow long groove or a high rib plate, is a small transitional arc.
