The CNC VMC850 vertical machining center has strong rigidity, convenient and flexible operation, and fully enclosed protection. Suitable for box-type parts, various complex two-dimensional and three-dimensional mold cavity processing. After the parts are clamped at one time, multiple processes such as milling, drilling, boring, dumpling, and tapping can be completed. In daily use, how does the device need to be debugged, and what is the correct operation method?
Operation method of CNC VMC850 vertical machining center:
As a skilled operator, only after understanding the requirements of the machined parts, the process route, and the characteristics of the machine tool, can the machine tool be manipulated to complete various processing tasks. Therefore, a few key points of operation are sorted out for reference:
1. In order to simplify positioning and installation, each positioning surface of the fixture should have precise coordinate dimensions relative to the machining origin of the CNC VMC850 vertical machining center.
2. In order to ensure that the installation orientation of the parts is consistent with the direction of the workpiece coordinate system and machine tool coordinate system selected in the programming, and directional installation.
3. It can be disassembled in a short time and changed into a fixture suitable for new workpieces. Since the auxiliary time of the CNC VMC850 vertical machining center has been compressed very short, the loading and unloading of the supporting fixtures cannot take up too much time.
4. The fixture should have as few components as possible and high rigidity.
5. The fixture should be opened as much as possible, the spatial position of the clamping element can be lower or lower, and the installation fixture should not interfere with the tool path of the working step.
6. Ensure that the processing content of the workpiece is completely completed within the stroke range of the spindle.
7. For the CNC VMC850 vertical machining center with an interactive worktable, due to the movements of the worktable, such as movement, lifting, lowering and rotation, the fixture design must prevent the spatial interference between the fixture and the machine tool.
8. Try to complete all the processing content in one clamping. When it is necessary to replace the clamping point, special attention should be paid not to damage the positioning accuracy due to the replacement of the clamping point, and explain it in the process document if necessary.
9. 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 is not greater than ra3.2μm.
Debug method:
1. According to the requirements of the manual, add oil to each lubrication point of the CNC VMC850 vertical machining center, fill the hydraulic oil tank with hydraulic oil that meets the requirements, and connect the air source.
2. Power on the CNC VMC850 vertical machining center, and supply power to each component separately or after a power-on test for each component, and then fully supply power. Check whether there is an alarm for each component, check whether each component is normal, and whether each safety device works. Make every link of the machine tool can operate and move.
3. Grouting, after the CNC VMC850 vertical machining center starts to work, roughly adjust the geometric accuracy of the machine tool, and adjust the relative orientation of the main moving parts that pass through disassembly and assembly and the host. Align the manipulator, tool magazine, communication table, orientation, etc. After these operations are completed, the anchor bolts of the main engine and various accessories can be filled with quick-drying cement, and the reserved holes of the anchor bolts can be filled.
4. Debugging, prepare various testing tools, such as fine level, standard square feet, parallel square tubes, etc.
5. Fine-tune the level of the CNC VMC850 vertical machining center, so that the geometric accuracy of the machine tool is within the allowable error range, using multi-point pad support to adjust the bed to the level in a free state to ensure the stability of the bed after adjustment .
6. Adjust the position of the manipulator relative to the main shaft by manual operation, and use the adjusting mandrel. When installing a heavy tool holder, it is necessary to perform automatic exchange of the tool magazine to the spindle position for many times, so as to be accurate and not collide.
7. Move the worktable to the exchange position, adjust the relative position of the pallet station and the exchange worktable to achieve smooth automatic exchange of worktables, and install a large load of the worktable for multiple exchanges.
8. Check whether the setting parameters of the numerical control system and the programmable controller device conform to the specified data in the random data, and then test the main operation functions, safety measures, and the implementation of common instructions.
9. Check the working conditions of accessories, such as machine tool lighting, cooling shields, various guards, etc.
