How to maintain the laser machine?
14 Aug , 2020
With the application of laser machine more and more widely, we need to laser machine more and more places.How to maintain the laser machine?How to deal with the problem of laser machine?
1, linear guide guide lubricating oil: laser engraving machine used for a period of time, engraving, cutting the smoke, dust has a corrosive effect on the guide, so it is necessary to maintain the guide regularly.Turn off the laser engraving power, clean the guide rail with a clean soft cloth, and then drip lubricating oil on the guide rail. After lubricating oil is finished, let the slider roll back and forth in the guide rail to ensure that the lubricating oil enters the inside of the slider.When the oil is finished, let the slider roll back and forth in the guide rail. Then, install the guide rail first. Pay attention to not fixing the guide rail first, install all the fixing nails and keep them horizontal, fix the belt and the slider, then install the lens, and adjust the X direction.
2, mirror focusing mirror wipe: Laser engraving machine Laser cutting machine after using for a period of time, smoke and dust will adhere to the lens surface, affect the engraving, cutting depth, will also affect the engraving, cutting accuracy.Generally in a week or so (according to the use of laser cutting machine engraving machine frequency) with anhydrous alcohol will be three mirrors, a focusing mirror carefully wipe clean.
3, bearing oiling: laser cutting machine to use a lot of bearing, in order to ensure good cutting, carving effect, part of the bearing need regular gas (except oil bearing), with a clean soft cloth on the bearing of the floating of erase, the oil suction needle by needle, and then inject slowly with the needle bearing, slowly rotating bearing when filling in
4. Elastic adjustment of synchronous belt (belt) : There are several synchronous belts in the driving system of laser cutting machine
. If the belt is too loose, the engraving font will double; if the belt is too tight, the belt will wear down.After using for a period of time, please adjust the tensioning screw of the synchronous belt, adjust the synchronous belt to the appropriate elastic, engraving text does not appear double shadow, and laser engraving machine laser cutting machine running noise is very low, or consult the technical personnel of the manufacturer.
5, the maintenance of the laser tube, laser engraving machine, laser tube is the use of circulating water cooling, use for a long time, the tube there will be some white scale, we can join a small amount of vinegar in the circulating water, drain away the tube, and then use clean water to laser tube inner loop washed clean, so that the laser tube will be in the best working state, the life will be extended.
Problem 1: When opening the software, the computer prompts "Failed to open the card, please check the prompt of the card" solution:
Solutions: 1. Check whether the driver of the board card is installed or change the board card into a PCI slot; 2.2. Reinstall the two data connection wires to check whether there is a broken needle;3. If there is a problem with the board card, replace it.
Problem 2: When opening the software, prompt: three-axis alarm, initialization error Number 4.
Solutions :1. Check whether the two data cables of the computer and the machine are properly connected; 2.2. Check whether the fuse of the transfer board in the control box is burned off and change the fuse;3. Check whether the 5V12V power supply is normal
Problem 3: There is a misalignment during engraving, or the size is wrong,
Solution 1. Check whether the path of engraving software is correct or not;2. Check the clearance size of the screw rod and whether the fastening screw of the polished rod is loose;3. Check the correct setting of software parameters
Question 4: when walking on the X-axis for a certain period, the axis does not lift the knife. Press up to walk but down.
Solutions :1. Check whether the Z-axis motor is in normal operation, power and drive current; 2.2. Check whether the z-axis motor wire has bad contact or discontinuous in the middle
Problem 5: Spindle motor does not turn or reverse
Solution :1. Check the parameter setting of frequency converter; 2.2. Whether the signal line of the frequency converter is connected backwards
Question 6: There is a phenomenon of knife smashing.
Solutions :1. The z-axis motor is not powerful enough, and the coupling is loose; 2.2. The current of shaft driver is too low, or the signal wire is connected wrong
Problem 7: When the software is turned on, the shaft is turned off.
Solutions : 1. Problems with the driver or bad contact of the computer output signal line;2. Poor motor wire contact
