Cutting the concept of machine surface roughness
In the manufacturing process of mechanical parts, the knives left by the cutter or the grinding wheel, the plastic cross in the process of chip separation, the vibration of the machine tool, etc., always leave a small gap and peaks and valleys on the friendly side of the part. Roughness. These inhomogeneities can be seen with the naked eye on the rough surface or after finishing with a magnifying glass or microscope: the finished surface can be observed with a magnifying glass or microscope. To this extent, the height and spacing of the small peaks and valleys on the surface of the part is referred to as surface roughness or micro-roughness. Precautions:
The automatic cutter manufacturer will use the level to adjust the horizontal position of the machine.
Remove the fuel tank cap and add about 120 liters of hydraulic oil for the hydraulic oil brand. Pay special attention to the cleanliness of the hydraulic fluid.
Connect the correct three-phase power supply to the machine. Pay special attention to the voltage of the three-phase power supply should be consistent with the voltage indication on the machine nameplate.
Turn on the machine and check the motor direction.
Set the height of the tool mold to the appropriate depth and the machine is ready for operation.
There are many manufacturers' machines that will experience uneven pressure after a period of time. The general reasons are as follows:
1. Long-term overpressure use.
2. The large workbench is used with the small knife mold for a long time, and is used in an eccentric position.
3. The die is used for a long time around.
4. Enough to buy low quality, low cost machines from small factories.
The above is roughly the reason for the uneven pressure of the cutting machine manufacturers.
How to solve: Generally speaking, there are several kinds of uneven pressures, such as different depths before and after, different depths on the left and the right, and different depths in the whole area. If the depth of the entire area is different, it can be solved by correction. The entire area needs to be reprocessed (back to the factory is more troublesome).
In order to make the cutting machine equipment have a long service life, daily maintenance work is essential! Good maintenance maintains the good performance of the cutting machine and the life of the part.
