Do you want to receive change for laser cutting? What does laser cutting do?

Laser cutting does not need to be connected to the zero wire, because it is cut at the speed of light emitted by a special laser.

This must be connected to the zero wire, because if he is connected to the zero wire, the speed of his result may become a little faster, so in the next process, you can wire it according to his wiring instructions.

All single devices must be connected to the neutral and ground wires of the live wire, and you should be talking about the ground wire, not the neutral wire. But it must be grounded, and it is very dangerous not to be grounded.

Laser cutting should need to be replaced with change, this should be connected to the zero line, if you don't approve of staying, he should not be able to guarantee the safety.

Of course, it is also necessary to connect the zero wire, so that the laser cutting is more powerful and safer.

It is best to pick up Ningxian, because Ningxian is safer when it is accessed, and it can ensure that it is safer when cutting.

Hello, here I helped you inquire, you need to connect the zero line, you can go to the master of the practitioner to help you take a look.

Laser cutting does not need to be connected to the zero line, laser cutting does not need to be connected to the zero line.

Laser cutting should be corrected to connect the zero line, so that it can be carried out first, otherwise it is not in zero three, there should be no way to use it.

In order to ensure safety, it is also necessary to connect the zero line.

Glad for your question, don't connect the zero line here, because it's normal, some zero line it will cause some specific reactions.

Generally, if you have this kind of number of days, you can check it online.

This is actually very simple, he doesn't need to take it, this is okay.

Laser marking technology is one of the largest application areas for laser processing. Laser marking is a marking method that uses a high energy density laser to irradiate the workpiece locally, so that the surface material vaporizes or undergoes a chemical reaction of color change, so as to leave a permanent mark. Laser marking can print a variety of words, symbols and patterns, etc., and the character size can range from millimeters to microns, which has special significance for the anti-counterfeiting of products.

The ultra-fine laser beam after focusing is like a tool, which can remove the surface material of the object point by point, and its advancement lies in the fact that the marking process is non-contact processing, and does not produce mechanical extrusion or mechanical stress, so it will not damage the processed item; Due to the small size of the laser focus, the small heat-affected area, and the fine machining, it is possible to complete some processes that cannot be achieved by conventional methods.

The "tool" used in laser processing is the focused light spot, which does not require additional equipment and materials, and can be continuously processed for a long time as long as the laser can work normally. Laser processing is fast and inexpensive. The laser processing is automatically controlled by the computer, and there is no need for human intervention during production.

Laser marking technology function:

What kind of information can be marked by the laser, only related to the content of the design in the computer, as long as the artwork marking system designed in the computer can be identified, then the marking machine can accurately restore the design information on the appropriate carrier. Therefore, the function of the laser marking software actually determines the function of the laser marking system to a large extent.

Laser gases are oxygen, carbon dioxide, helium! The cutting gas is oxygen and nitrogen, but this is a CO2 laser.

Carbon dioxide glass laser tube.

First, the obvious advantages of laser cutting technology over other methods.

1) Cut***. The width of the incision is narrow (generally high precision (general hole center distance error, contour size error, good incision surface roughness (generally RA, the cut seam generally does not need to be reprocessed to weld.

2) The cutting speed is fast. For example, with 2kw laser power, the cutting speed of 8mm thick carbon steel is; The cutting speed of stainless steel with a thickness of 2mm is small, the heat affected zone is small, and the deformation is minimal.

3) Clean, safe and pollution-free. The working environment of the operator is greatly improved. Of course, in terms of accuracy and incision surface roughness, CO2 laser cutting cannot surpass electrical machining; In terms of cutting thickness, it is difficult to reach the level of flame and plasma cutting.

However, the above significant advantages are enough to prove that CO2 laser cutting has replaced and is replacing some traditional cutting methods, especially the cutting of various non-metallic materials. It is an advanced processing method that is developing rapidly and is becoming more and more widely used.

4) Non-contact cutting. There is no contact between the torch and the workpiece during laser cutting, and there is no wear and tear of the tool. Machining parts of different shapes does not require changing the "tool", only the output parameters of the laser need to be changed. The laser cutting process has low noise, low vibration and no pollution.

5) There are many types of cutting materials. Compared with oxyacetylene cutting and plasma cutting, there are many types of laser cutting materials, including metal, non-metal, metal-based and non-metal-based composites, leather, wood and fiber. However, for different materials, due to their different thermophysical properties and laser absorption rate, they show different laser cutting adaptability.

Second, the disadvantages of laser cutting.

Due to the limitation of laser power and equipment volume, laser cutting can only cut plates and tubes of medium and small thickness, and with the increase of the thickness of the workpiece, the cutting speed decreases significantly. Laser cutting equipment has a high cost and a large one-time investment.

1.Abide by the safety operation procedures of the cutting machine and operate in strict accordance with the operating instructions;

2.The operator of the laser processing machine must be specially trained, reach a certain level, and be allowed to operate under the premise of the consent of the safety administrator;

3.Specify the laser safety management area, and set up warning signs at the entrances and exits of the management area, including: the power of the laser processing machine, the type of laser, the prohibition of outsiders from entering, the protection of eyes and the name of the safety manager, etc.;

5.When the equipment is working, the operator shall not leave the post or entrust someone to take care of it without authorization, and shall cut off the power or stop the machine;

6.The operator of the laser processing machine or the personnel who approach the laser during the use of the laser should wear appropriate laser protective goggles and wear protective clothing, and there must be good indoor lighting in the area where the protective goggles are worn to ensure the smooth operation of the operator;

The laser cutting machine has a lot of laser energy, so you should pay attention to safety, wear glasses, and it will also produce a lot of dust, so you have to wear a mask. The cutting material is sharp, wear gloves. Laser People Home replied Hope to adopt Thank you.

1. The operator must strictly abide by the safety operation procedures of the laser cutting machine.

2. The operator must consult all the instructions that come with it or have received the training of our customer service personnel, and be familiar with the equipment structure

performance, master the knowledge of the operating system.

3. Wear labor protection equipment according to the regulations, and wear protective glasses that meet the requirements near the laser beam.

4. Do not process a material before it is clear whether it can be irradiated or heated with a laser, so as not to produce smoke and vapor.

potential dangers.

5. When the equipment is started, the operator shall not leave the post without authorization or entrust someone to take care of it.

The primary factor in purchasing equipment is that the performance of the equipment should be stable and the quality should be good. At present, many laser equipment manufacturers are developing new products while ignoring the improvement of old product quality. This requires us to keep our eyes open when purchasing, and to analyze the structure of the product, especially the selection of laser processing equipment, to understand whether its mechanical properties are reasonable and reliable, whether the software control is convenient to operate, whether the connection between the computer and the equipment is very convenient, and whether the operation process is very clearly manifested.

Any piece of equipment will be damaged to varying degrees during use, so in terms of repairing after damage, whether the maintenance is timely and the cost has become the second issue to consider. Therefore, in the purchase, it is necessary to understand the after-sales service problems of the enterprise through a variety of channels, such as what the response mechanism is, whether the maintenance charges are reasonable, and so on. In fact, buying is a very simple process, and the choice is the most important thing, which needs to be investigated.

How to choose a good laser engraving and cutting machine.

There are many brands and types of small laser cutting machines on the market, and the following Hanma will teach you how to choose a good machine.

1. Pay attention to the function of the engraving machine, the engraving motor of the engraving machine has high power and small power. Some engraving machines are only suitable for the processing of materials such as two-color plates, architectural models, small signs, three-dimensional handicrafts, etc., this process has been popular for a while, but because the engraving power is too small, it greatly affects its application range. The other is the engraving machine with a high-power engraving head, which is divided into two categories, one is a large-format cutting machine

The format is generally more than one meter, but this.

The accuracy of the engraving machine is generally poor; The other type is the medium-format engraving machine: this kind of engraving machine is generally used for fine processing and organic signage production.

2. To understand the performance and function of the engraving motor, the engraving head motor of the engraving machine is also very critical, and the engraving head motor is working continuously for a long time, so if the engraving head motor is not good, it will also affect the use of the engraving machine.

3. The second is the speed adjustable range of the engraving head motor, the general speed adjustable range is several thousand to 30,000 revolutions per minute, if the speed is not adjustable or the speed adjustable range is small, then it means that the application range of the engraving machine is greatly limited, because the engraving of different materials must use different engraving head speeds.

4. The manufacturing process of the engraving machine body: the high-power engraving machine requires the body to be precise and stable when working, so the platform on which the guide rail is installed must be horizontally milled. The installation platform of Hanma laser is one of the few in the industry that is processed by a large gantry milling machine, and the precision and stability of the laser engraving machine have been rapidly improved.

5. The controller is generally divided into two categories: one type of controller is only to drive, and all its computing work is completed by the computer, and the computer is in a waiting state when the engraving machine is working, and the typesetting work cannot be carried out. Another kind of controller adopts single-board computer or single-chip microcomputer control, this controller is actually a computer, so as long as the engraving machine starts to work, the computer can immediately carry out other typesetting work, especially when engraving for a long time, the advantage is particularly obvious.

6. Screw rod and guide rail are also an important part of the engraving machine, good screw rod and guide rail is the guarantee of its accuracy and performance when the engraving machine is used for a long time.

7. No matter how good a laser cutting machine is, users will encounter a variety of problems in the process of use, and when encountering unsolvable problems, whether the enterprise can provide timely solutions is particularly essential, which is also an important factor for users to consider in the purchase of laser cutting machines.

Quality, after-sales service, if you are not buying a local machine, you have to see if there is an after-sales point in your local area, in case there is a problem with the machine, you can't find the after-sales one.

1.First of all, when we buy a laser cutting machine, we must understand what kind of material and thickness this machine can cut, and what kind of specific products can be produced and processed, so that we can choose the appropriate laser cutting machine according to our needs.

2.Is the strength of the manufacturer of laser cutting machine big enough? This can be judged by the number of users of the manufacturer's high-power laser cutting machine, and it is best to choose a manufacturer with an annual output of more than 100 high-power laser cutting machines.

Because some leather bag companies sell a few units a year, they will not produce laser cutting machines in a few years, and customers will not be able to maintain the equipment after a few years.

3.Is the ** of the laser cutting machine reasonable? Understand the market price, ** too high must be bargained. Too low, pay attention to the quality.

4.Is the after-sales service timely? When you hear the manufacturer tell you that there is an after-sales service point in the local area, you must take the time to go to the scene to see whether the manufacturer's after-sales service store and service personnel are really in the local, and to see if there are spare parts in the local area, otherwise, if there is a failure, you have to wait for the accessories, and other maintenance personnel from the field to do the train over, at least 2 days or more.

If you can't buy a train ticket, you'll have to wait a few more days.

5.Is the steel plate laser cutting machine a flying optical path? At present, the flying optical path technology of the laser cutting machine has been very mature, and the vast majority of manufacturers can do it, if there are manufacturers who recommend mixed optical path or semi-flying optical path laser cutting machine to you, then you must stay away from him, because this outdated technology has long been abandoned by the laser industry in the field of steel laser cutting machine, and only a very small number of foreign brands are still recommending this outdated product to Chinese users.

6.Is the laser power appropriate? At present, the laser power used for steel plate laser cutting is generally 2000w 3000w 4000w, if someone recommends a laser below 2000w, you must not choose, because it is unbearable; If someone recommends a laser above 4000w, you should also think carefully about whether it is necessary.

7.Finally, when we choose, we should also pay attention to whether the use of laser cutting machine can save various raw materials, and some machinery will waste some consumables in the process of use, so that our cost will be greatly increased, and if we reduce the intake of these costs, our profit point will become larger. Therefore, the energy saving of the laser cutting machine is also crucial.

Lixing Laser (a large domestic laser cutting machine manufacturer, ISO9001-ISO2000 certified enterprise, EU CE certification and Swiss SGS certification enterprise, the production of laser cutting machine any graphics and text, very convenient and easy to operate: environmental protection, pollution-free.
