**How to determine the lubrication condition of a twisted axis CNC bending machine and take appropriate lubrication measures**
1、 * * Determine lubrication condition**
1. * * Machine tool surface observation method * *:
-The operator observes whether there are obvious overheating, wear, scratches, and other phenomena on the surface of the machine tool while it is running.
-If the surface color changes, turns black, or shows obvious wear, it may be the result of inadequate lubrication of the machine tool.
2. Machine tool refueling detection method:
-By sampling and testing the lubricating oil of the machine tool, determine whether the lubrication system of the machine tool is normal.
-Regularly take samples to test the acid value, viscosity, moisture and other indicators of the oil. If the test results do not meet the requirements, it indicates that the machine tool lubrication is not in place.
3. * * Machine tool sound detection method * *:
-The normal operation sound of the machine tool should be low noise.
-If the lubrication is not in place, the machine tool will produce abnormal noise, and the operator can make a preliminary judgment by listening to the sound.
4. * * Machine tool surface temperature detection method * *:
-If the lubrication of the machine tool is not in place, it will cause an increase in friction and heat of the machine tool components, resulting in an increase in the surface temperature of the machine tool.
-The operator can use a temperature detector to check the surface of the machine tool. If the temperature is too high, the lubrication system needs to be repaired.
2、 Take appropriate lubrication measures**
1. Lubrication method selection:
-Select appropriate lubrication methods based on the working conditions of the twisted axis CNC bending machine, such as box lubrication, regular lubrication, and oil-free self-lubricating.
-It is recommended to use oil cups to regularly add lubricating oil to each sliding guide surface, and the upper roller main transmission gear reducer should use box type lubrication.
2. * * Lubricating oil type selection * *:
-Calcium based grease is generally recommended for the composite bearings on the steel back of the roller shaft.
-If choosing other types of grease, it is necessary to ensure that the drip point of the grease is not lower than 160 ℃ and the penetration degree is within the range of 325-360.
3. * * Regularly add lubricating oil * *:
-Before starting work, it is necessary to lubricate each lubrication point with oil.
-After the equipment has been working for 150 hours, the lubrication system should be cleaned.
-The lubricating oil in the gearbox should be checked at all times to ensure that it is at the specified oil level.
-The lubrication system should be cleaned once a year.
4. Establish lubrication inspection records:
-Establish a lubrication inspection record table to record information such as the time, type, and amount of lubricating oil used for each lubrication.
-Regularly check records, analyze lubrication conditions, and provide a basis for adjusting lubrication strategies.
Through the above measures, the lubrication condition of the twisted axis CNC bending machine can be effectively determined, and appropriate lubrication measures can be taken to ensure the normal operation of the machine tool and extend its service life.
