Who knows the shortcomings of Atlas, demands objectivity and impartiality 20

Atlas. The main head is water-cooled, the heat dissipation at first is not bad, but it is easy to scale for a long time, and there will be a high-temperature jump in three days, especially its low-power machine, our company bought two in 2009, 75kw and 55kw, it was good to use at the beginning, and then there were a lot of problems since March last year, and it was annoyed to death every day, and the most hateful thing is its after-sales service.

Once I called ** at more than 10 in the morning to call their people to repair, but the next day at more than 1 o'clock in the afternoon, I almost let the boss to fire, alas, take the short hand, their machine actually uses a lot more electricity than the standard electricity power, especially a 75 and 75 +, at that time I was told that the actual consumption is 82 results in buying a machine to test is 98, their business is authentic **, sell out the machine will not do anything, now I am afraid that they will have problems, a problem The section chief asked me why, alas, I was killed.

Atlas first only produced twin-screw air compressors in China, and now it is the trend of single-screw air compressors. The single screw is more efficient, more energy-saving, more stable and more advanced than it. I think that the machines of some brands in our country have far surpassed them, because foreign countries have reservations about single-screw technology, so if you can buy Atlas's single-screw machine, the price is definitely more incomprehensible.

Second, Atlas's after-sales service is very poor, probably because they sell too much, once there is a problem, sometimes no one comes for a long time. And the cost is not generally high. I also suffered the loss of believing in foreign brands, and I will not consider foreign brands next time.

The neighbor unit bought 5 domestic machines, which is very good, and the brand is not reported in order to avoid suspicion. The monthly electricity bill is less than ours, and we only have 3 units. And the specifications are all about the same.

The operation is also stable. It hurt me to educate my boss a lot.

Upstairs two brothers, off and Atlas's after-sales service is very poor, I feel the same, but as far as Atlas products are concerned, it is still possible, as an international brand, in terms of technology can only be compared with Ingersoll Rand, the two products can be said to have their own merits, in terms of after-sales Ingersoll Rand's service is much better than Atlas, but the first aspect of Ingersoll Rand is a little higher, and one thing has to be said that our company just opened the factory in 2004 to buy two oil-free machines, At that time, there were these two to compete for the bid, because we just opened the factory, never used these two products, the company decided to buy one, in addition to the after-sales service is not the same, the product has not appeared a big problem, but Atlas loves high temperature jumping, from the end of the year before the beginning of Atlas gas volume has dropped a little, to February today, the gas volume is not very sufficient, and Ingersoll Rand's this year has also declined a little, and later maintenance of their service personnel to see, said that the host screw coating has a little bit off, So there was a drop in gas volume, and then they took it back and sprayed it again, and now the gas volume is the same as when I first bought it, Atlas they asked us to replace a pair of screw rotors, so from this point of view, there is no big gap in the quality of the two products in the first 5 to 6 years, and it will be different after the year, and now the company plans to add two injection production lines, and now there are two products in the long run, or Ingersoll Rand is slightly better, and the air compressor that is going to be added in the later period is still enough to order Ingersoll Rand.

The after-sales service is quite bad! Other models are not clear, we bought the oil-free air compressor SF6, and it took about 100 hours to repair the rotor. It took only 2 hours after 1900 years to repair, and the metal shell of the rotor cracked!

**Contact said that it was out of the warranty period, repair**40,000, call 400** to complain, and I felt that I was losing money and hung it directly** ignore you.

Now it is basically localized, high temperature, poor service, expensive accessories and so on. Don't be too superstitious about foreign cards. Otherwise, I really can't afford to hurt.

Where do you use it, the Atlas machine is prone to high temperature jumping! ~

First of all, according to the market share of mainstream brands: Japanese and European and American:

Japanese: (mainly the vast majority of domestic Japanese companies are theirs) are basically ESTIC DDK melon production technology research.

European and American departments: (The vast majority of European and American companies are theirs.) Atlas, Apex, Bosch, Horsehead, Depai.

Performance is comprehensive:

Tier 1: Atlas Rationale: After all, industry rule-makers.

The second ladder: horse head Apex estic Bosch Depa.

The third tier: Guasheng, DDK Technology, Ingersoll Rand, etc.

Advantages and disadvantages: the first ladder:

Atlas: Advantages: relatively high accuracy (with the technological progress of other manufacturers, there is not much difference from the second echelon), developed after-sales team, complete technical performance, industry overlord.

Disadvantages: ** is very high (now the market is sluggish and has begun to lose money to sell), the later cost is very high (after all, the after-sales network needs money), and the maintenance personnel have performance requirements.

Tier 2: There is not much difference in the technology of this echelon, but the focus is different.

Advantages: Matou: The technology is very close to Atlas, and it seems that it does not pay much attention to research and development, but it is very strong in marketing (please refer to various exhibitions), and their monitors are still very cost-effective.

Apex: Similar to the performance of the horse head, there is not much contact, no evaluation.

ESTIC: As the only Japanese company in the second tier. The pulse pattern was the first to be studied.

Dual-mode handheld is the selling point, ** is cheaper than European and American companies, and the later maintenance cost is also very low (Japanese general advantages), after all, Japan is also very fierce overtime, and it is not as old as Europe and has time to maintain. But the press or something is really average, so let's be an honest tightening machine.

Bosch: The business covers a wide range, in addition to servo tools, other clutch types, and ordinary tools are also done. I don't know much about it, so I don't make a review.

Depai: Different from the previous ones, this company mainly focuses on small torque, which also has advantages over the previous ones, and the accuracy below 5nm is high, so it is recommended to choose. **Slightly more expensive.

The third echelon, not to mention, in terms of servo tightening, there is a significant gap between the performance and the first two echelons, and there is no way to compare. In terms of advantages, it is cheaper than the first two tiers. If the technical requirements are not high, it is recommended to choose.

Personal opinion: do not wash and do not spray, if there is anything wrong, please correct and supplement. It's not easy to give a thumbs up for typing.

136 Saias 2926 Tightening Machine Composition: 9353, Ho.

Beijing Hyundai, Tianjin Pinghe Auto Parts (wheel assembly and spare parts tightening), Shandong Heavy Duty Truck, Hangzhou Heavy Duty Truck, Jaguar Land Rover, Shenyang Axle (screw tightening of tires, engine and axle assembly), Zoomlion, Sany Heavy Industry, Zhiqi, CNR Group EMU Project (high-speed rail wheels, brake disc assembly and twisting), CGN.

1. Tighten the main machine of the machine.

It mainly includes electric wrench assembly, tightening machine shell body, tightening machine control cable, etc.

2. Tighten the main control cabinet of the machine.

It mainly includes standard electrical cabinets, air conditioners, isolation transformers, low-voltage electrical components, distribution boards, a set of industrial computers and color displays, tightening machine system software, main control units and tightening shaft axis control units, etc.

3. Tightening machine hanging track system and balance suspension device.

It mainly includes rail pulleys, hoisting devices, balancers, cylinders, valves, hangers, booms, etc.

Nutrunner working engineering:

At the tightening station, the operator holds the handlebar, and adjusts the upper and lower height through the rising and descending buttons, controls the operation to make the tightening shaft sleeve align the nut and maintains a certain amount of compression, clicks the start button on the handlebar, and the tightening machine system will recognize the cap, tighten at high speed, sit down, pre-tighten, and finally tighten, and exit the automatic tightening process after unloading after qualification.

During the tightening period, if there is any unqualified, it can be automatically loosened and re-tightened, or it can be automatically reversed and loosened and tightened by the reset button on the operation box, or the unqualified can be loosened and tightened separately by the manual forward and reverse switch on the operation box.

Atlas. Pros of Copco:

Precision, Quality, Durability, Performance, Innovation, Functionality, After-sales Service, Ergonomics.

Better than other brands in terms of brand awareness, Atlas. Disadvantages of Copco:

**More expensive than other brands.

The tightening machine depends on which one, the wireless charging type is currently the most advantageous Ingersoll Rand, ** cheap things are good. Armed with a tightening wrench, Atlas, and a horse's head are good. The axis is not etic, plus the bus needs to be equipped with a main controller, the axis is the most cost-effective, it is not bad and maintenance-free, and the service is the best in several homes, Ingersoll Rand and Apex are rare now.

First of all, it is necessary to determine the specific needs, and Atlas and Ingersoll Rand have their own advantages in the full range of products. In terms of performance alone, Atlas will have some advantages over Ingersoll Rand, and if it is cost-effective, Ingersoll Rand will be more prominent. Ingersoll Rand's services have also been enhanced in recent years.

Don't choose DDK's, the quality stability and reliability are poor, and the service is not good. There is no direct sales in China.

Desoutter and Atlas are two brands that operate independently, not sub-brands, this must first be clarified, and secondly, Desoutter and Atlas are the most complete product lines, which can cover the entire production line, and function, durability, after-sales and so on are the first echelon, but ** is a little more expensive, other brand products are not so high-end compared to these two, and the product line is not so complete.

APEX is the most professional tool manufacturer in this industry, and the entire line of automotive assembly products can be covered. Including wire body, hand tools, power tools, nutrunners, professional sockets. Volkswagen, BMW, Mercedes-Benz, Ford, GM...

Big brand car manufacturers use it a lot. Disadvantages, late entry into China, many name changes, and poor publicity.

Both the Desoutter brand and the Atlas brand are owned by the Wallenberg consortium, and both companies are operated independently, so how can you say that they are affiliated.

Atlas COPCO is a leader in the field of assembly, the products are high-end assembly tools, the products are incomparable to other brands in precision control, assembly quality, ergonomics, but also relatively high, low-end tightening tools such as BCP is also about 1W, high-end such as PFD6000A tightening tool with a controller is also around 15w.

I have used Atlas, Horse Head, Estic, the first two are similar, because the first two are the same group, from the controller, stun gun, power arm, TPS are similar, there is a more obvious difference is the processing speed of the controller. Atlas is more than twice as fast as the horse, and with MES communication, the entire communication process takes 600ms for the Atlas and 1400ms for the horseIn addition, ESTIC, compared to the first two, it is pulsed, and the first two are direct, and the tightening accuracy is claimed to be 3%, which is higher than the first two, but in fact, it is also.

The communication is similar.

Ingholland is relatively cost-effective, and its life span is similar to that of Atlas.

Hydraulic pulse tools, Atlas's should be the best of this kind of tools, the best reason: the least reaction force, the lightest weight, the smallest volume.

However, the best cost-effective hydraulic pulse tool should be melon.

Hydraulic pulse tool (no matter whose tool it is), disadvantages:

1. The accuracy is not accurate, the hard connection is less than 10%, the soft connection is less than 25%, and there is drift.

2. Difficult maintenance, low life and high failure rate. No matter who you are, you need to tighten it 20,000 times to change the oil, and when you change the oil, you need to vacuum and remove bubbles. If the maintenance is not in place, 100,000 times tightening is the limit of this type of tool, and even if it is maintained in time, it may be 300,000 times of tightening is also the limit of this tool.

The most feared problem of this kind of tool is oil leakage, once the oil leaks, it is basically equivalent to scrapping, and it is difficult to repair. (This shortcoming: no matter whose salesperson you don't ask, he won't tell you, even if you ask, some salespeople will make up some lies, and Hulong claims how advanced his tools are.) Because, by the time you find out, he's already got the sales).

3. It is difficult to set the torque, because the tool is tightened by impact force, it is not very suitable for the torque tester to set the torque, the torque needs to be detected by the marking method, and it is very difficult to adjust the torque.

Advantages of Hydraulic Pulse Tool:

The reaction is much smaller than the tightening torque, and the tightening torque of 600 Nm can be held by human hands.

The specific contrast is the kind, and the tools they involve are too extensive.

Pneumatic ones are also divided into hydraulic pulse type, impact type, mechanical type, wrench, tightening machine, direct drive type, automatic type, semi-automatic type, gun type, straight type, angle type, etc.

They are all international first-line brands, but the business priorities of each brand are different. Atlas Copco has a rich product line of air compressors, among which the market share of oil-free compressors is very high.

In terms of air production quality, under the same power consumption of Atlas, the gas production is large, and the air oil content is low; In terms of the cost of the first equipment purchase, there is little difference between Atlas Copco and Ingerso, and God is just cheaper. After-sales service outletsAtlas has many service outlets, which is more convenient.
