The characteristics of the vertical machining center and its debugging method sharing

The vertical machining center is the main shaft perpendicular to the workbench. It is mainly suitable for the processing of plates, plates, molds and small shell parts. It is at least three-axis and two-linkage. Generally, three-axis and three-linkage can be completed, and some can be used by five to six axes. control.

The vertical machining center is convenient for workpiece clamping and positioning, the tool movement track is easy to observe, the debugging program is convenient for inspection and measurement, and problems can be found in time, and the machine can be stopped or modified. The cooling conditions are easy to set, and the cutting fluid can directly reach the tool and the processing surface. The Cartesian coordinate system is consistent, the feeling is intuitive, and the viewing angle of the pattern is the same.

Features:

1. Low fuel consumption and cost saving;

2. There is no problem of difficult atomization of high-viscosity lubricating oil; it is suitable for any oil;

3. Environmental protection and no pollution. Because there will be no oil mist sprayed out, it will not pollute the surrounding environment;

4. The oil supply is accurate. According to different needs, the oil can be delivered to the lubrication points such as the main shaft and screw by adding a regulating valve;

5. Automatic detection and monitoring. It can detect whether the lubricating oil is normal. If the lubrication is poor, it can alarm and stop to avoid abnormal operation of the equipment;

6. Rolling bearings are especially suitable for main shafts. It has a certain air cooling effect, which can reduce the working temperature of the bearing, thereby prolonging the service life of the spindle.

 

Debugging method:

1. Add oil to each lubricating point, fill the hydraulic oil tank with hydraulic oil that meets the requirements, and connect the air source.

2. Power on, supply power to each component separately or after a power-on test for each component, and then fully supply power. Observe whether there is an alarm for each component, check whether each component is normal manually, and whether each safety device works, so that all aspects of the machine tool can be operated and get moving.

3. Grouting. After the initial operation, roughly adjust the geometric accuracy of the machine tool, and adjust the relative position of the disassembled main moving parts and the main machine. Align the tool magazine, manipulator, exchange table, position, etc. After these tasks are completed, the anchor bolts of the main engine and each accessory can be filled with quick-drying cement, and the reserved holes of the anchor bolts can be leveled.

4. Debugging. Prepare various testing tools, such as precision levels, standard square feet, parallel square tubes, etc.

5. Finely adjust the level of the machine tool to make the geometric accuracy within the allowable error range, use multi-point pad support, adjust the bed to level in the free state, and 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 adjustment mandrel. When installing a large-weight tool holder, it is necessary to perform multiple automatic exchanges from the tool magazine to the spindle position to ensure accuracy and no impact.

7. Move the workbench to the exchange position, adjust the relative position of the pallet station and the exchange workbench to achieve a stable automatic exchange of the workbench, and install a large load on the workbench for multiple exchanges.

8. Check whether the setting parameters of the numerical control system and programmable logic controller PLC device conform to the specified data in the random data, and then test the main operating functions, safety measures, and the execution of common instructions.
