Cutting machine surface roughness concept
In the manufacturing process of mechanical parts, the knife gangrene left by the cutting tool or grinding wheel, plastic crossing in the process of chip separation, machine tool vibration and other factors, always leave a small gap on the adjacent surface of the parts composed of small spacing and peak valley. These inhomogeneity can be seen with the naked eye on a rough surface or with a magnifying glass or microscope after finishing: the surface after finishing can be seen with a magnifying glass or microscope. To this extent, the height and spacing of small peaks and valleys on the surface of a part is called surface roughness or microroughness. Notes:
The manufacturer of the automatic cutting machine will use a level gauge to adjust the horizontal position of the machine.
Remove the cap and add about 120 liters of hydraulic oil, suitable for hydraulic oil brand. Please pay special attention to the cleanliness of the hydraulic oil.
Connect the three-phase power supply with the correct voltage to the machine. Special attention should be paid to the voltage of the three-phase power supply in accordance with the voltage indication on the machine nameplate.
Turn on the machine power and check the motor direction.
Set the height of the tool die to the appropriate depth and the machine is ready to operate.
There are many manufacturers of the machine after a period of time will be uneven pressure, the general reasons are as follows:
1. Long-term overpressure use.
2. Large worktable is used with knife die for a long time, eccentric position is used.
3. The tool die is used around for a long time.
4. Enough to buy low-quality, low-cost machines from small factories.
The above is the reason of the uneven pressure in the cutting machine factory.
How to solve: generally speaking, there are several kinds of uneven pressure, such as the depth before and after different, the depth of the left and right different, the depth of the whole area is different. If the depth of the whole area is different, it can be corrected. The whole area needs to be reprocessed.
In order to make the cutting machine equipment has a longer service life, the daily maintenance work is essential! Good maintenance can maintain the good performance of the cutting machine and the service life of the parts.
