What is a CNC machine tool for, and is it dangerous?

CNC machine tool is a kind of mechatronics equipment, which is an advanced machining equipment integrating computer, electrical control and mechanical structure. It is a special tool to cut materials to complete the machining of parts.

The operation of any equipment is standardized, and there will be no danger as long as it is operated safely according to the specifications. The machine tool itself will not be **, but if the operation is improper, the program error will appear some other dangerous phenomena: hitting the knife, hitting the machine tool, and things flying out and hurting people and hands.

CNC machine tool is a kind of machine digital control processing equipment, which is different from ordinary machine tools and is safer and more reliable than ordinary machine tools.

If you want to say that it is dangerous, it must be a little, any profession has a certain degree of danger, if you operate safely according to the norms, there will be no danger, if you are a girl, it is not recommended that you engage in this industry.

When you process magnesium or graphite, do you say that there is a possibility of the first grade, and when you use oil cooling, is there a possibility that the cooling oil is not selected correctly? Of course, the machine tools used to process these materials have special protection measures, but they cannot be completely eliminated! Ordinary CNC machining machine tools basically will not have the possibility of **!

If you want to learn CNC technology, if your mathematical foundation is okay, I suggest you go to the factory to hone it directly, and don't go to any technical school! What is taught in school basically does not work properly!

Your idea is really a bit fanciful. CNC machine tools are used to process the required contour parts with CNC instructions. The most dangerous thing is not **, but the collision, that is, there is a wrong knife path, or the wrong knife setting.

The spindle collides with the workbench or workpiece, and because it is closed, it is relatively safer than a normal machine.

The machine tool controlled by digital technology is used for precision machining. How can the machine tool be **, at most it is broken. As for there, I haven't been there, but generally those places don't have a good school spirit!

The lathe is a dangerous type of work, only if you violate the operating regulations, it will be dangerous, but it will not **.

I'll go, the first time I've heard of the machine tool!

Yes, go straight to the factory and learn.

1. Long-term contact with cutting fluid is easy to cause allergies!

2. If the lathe door is not closed during cutting, the workpiece is thrown out by the spindle and hurts people.

3. Programming error, or manual operation error, collision knife.

4. Iron slag flies out and into the eyes.

The workpiece flies out and hurts people, and the spindle rotates to bring people in.

Generally speaking, there are object strikes, machines.

Assault injuries, electric shocks, bai burns,

fire, poisoning and suffocation, and other injuries. The DAO depends on the actual distribution of hazards.

You can check the "Classification Standards for Accidents of Enterprise Employees".

The harm of dry CNC lathes to people includes: damage to hearing, respiratory tract and lungs will be infected, and the body will be polluted.

1. Damage to hearing.

Noise pollution, the workshop is very noisy. In the long run, it can cause damage to people's hearing, and in the most serious cases, even deafness.

2. The respiratory tract and lungs will be infected.

Iron dust pollution, some debris will be generated when machining parts. In the long run, a person's respiratory tract and lungs will be infected, and then develop related diseases.

3. The body is polluted.

The body is polluted by contaminated working fluids, and most of the parts are turned with alkaline machining fluids, which will be polluted by long-term contact.

Because CNC is the position of workers, when workers are very tired, and easy to get injured, it is easy to grind to the hands when sharpening the knife, the workpiece is easy to fall and hit the feet, the oil is easy to dirty clothes, and the hands can not be cleaned.

Precautions for CNC lathe work:

1. The workpiece must be clamped firmly.

2. Do not open the machine door during automatic processing.

3. Don't operate the machine tool with long hair, be sure to wear a work cap to work.

4. When the machine tool is running, it is strictly forbidden for anyone to invade the rotating work area with attachments.

5. Do not adjust the nozzle of the coolant when the CNC lathe is stopped.

6. Do not touch the rotating workpiece and spindle by hand or other means.

7. In the case of high-speed operation of the chuck, the jaw must clamp the workpiece to prevent the jaw from being thrown out during operation.

8. Do not wear gloves to operate the switch, otherwise, it may cause misoperation.

9. Do not pull the gear lever when the spindle is running.

10. Do not clean up the chips during the turning process.

11. When operating the machine tool, do not open the machine tool protection door.

12. The installation or removal of the tool should be carried out in the parking state.

13. When processing magnesium alloys, gas masks should be worn during operation.

14. Heavy workpieces need to be moved, and two or more people should work together to avoid danger.

15. Personnel operating forklift lifts, cranes or similar equipment or hooks must be professionally trained and accredited.

16. When operating forklifts, cranes or similar equipment, be careful not to collide with surrounding facilities. <>

CNC machine tools will have certain harm to the human body, especially the (water-based) cutting fluid used in CNC machine tools for a long time, which is more harmful.

1. It hurts, and after touching, it is dry, itchy, yellow, and some will peel off after a day or two. In the short term, you can resist it, and the delamination is good.

2. If you have long-term contact, it will be cracked, rough and ugly. The above is a white (light yellow) cutting fluid, commonly known as soapy water, which is slippery and greasy. The oil should be better, such as diesel and engine oil, which should be of higher purity and clear in color.

But the cost is higher. And the smell is heavier, often after returning home, there is a strong smell of oil, not to mention in winter, even on the quilt where you sleep, and the clothes are full of this smell inside and out.

3. In addition to the injury, other aspects are good, many mechanical industries and these have dealt with a lifetime, there is not much harm to the body, but a pair of hands is ugly. If you want to take good care of yourself, use more hand cream and make it a habit to wipe your hands whenever you wash them, and summer is no exception.

4. CNC machine tools use less soapy water and more diesel. Nitrogen can also be used to replace cuttingLiquid nitrogen is the most abundant component in the atmosphere, and liquid nitrogen, as a by-product of the oxygen production industry, is rich in resources. Liquid nitrogen is used as cutting fluid, which is directly volatilized as nitrogen and returned to the atmosphere after use, without producing any pollutants, which is a promising alternative to cutting fluid from the perspective of environmental protection.

5. The operation layout of CNC machine tools has a certain radiation to the human body. <>

There is basically no danger.

Dealing with metal and knives, bumps and bumps are inevitable, scratches and cuts are inevitable, and it is also possible to break the eyes, but there are few major accidents, such as the bridge factory, there are many sources of danger that cause death, but I have not heard of cases of death caused by dry numerical control.

The degree of danger of CNC machining in the safety supervision bureau belongs to the type of work that cannot be ranked, and it is much safer than that of drivers, chefs and other industries.

The work direction of CNC major mainly includes the following four aspects: CNC operators, CNC programmers, CNC maintenance personnel or after-sales service personnel, and CNC sales personnel.

First, you can choose to be a CNC operator, after CNC internship and CNC operation training students can be competent, but this job competition pressure is the greatest, any engineering higher vocational has this major, not to mention secondary vocational and technical school students.

At present, the CNC operation positions of China's machining industry have basically reached saturation. This work is not about the present, but about the development of the future.

Second, CNC programmer. At present, many machining socks companies use automatic programming to generate CNC machining programs, so they need to learn CAM software. Different units use different CAM software, and there are many types, but in general, the processing methods are similar, so you must learn one well.

However, being a CNC programmer is very demanding and has a lot of responsibility, so it requires rich processing experience. In this case, it is not realistic for students who have just left school to do this position immediately. It must go through a period of exercise, as short as one or two years, and as long as three or five years.

3. CNC maintenance personnel or after-sales service personnel. This position is more demanding and is the most lacking in numerical control. It is necessary to have not only a wealth of mechanical knowledge, but also a wealth of electrical knowledge.

If you choose this path, it can be very hard (such as frequent business trips), and you have to keep learning and accumulating experience.

Fourth, CNC sales personnel. The salary of this position is the most lucrative, and the professional knowledge required is not so much, but it requires outstanding eloquence and good social skills, which is not something that ordinary people can do.
