The machine tool develops from manual to CNC, and the production efficiency of one machine is equal to the past ten machines.
Numerical control technology has got rid of human factors in terms of accuracy and adaptability, and is completely controlled by computer, which guarantees extremely high parts consistency.
Regardless of what weird parts are processed, it is nothing more than a program control problem for the computer.
In the past, machining of turbines and screws was extremely difficult work, requiring a skilled worker with more than seven or eight years of experience to be competent.
Now, as long as the machine has the corresponding ability, ordinary secondary school students with a few months of training can do it.
CNC machine tools are so good, but the country basically relied on imports in the 1990s, such as Japan's FANUC.
People can still value you when they sell it to you, and many restrictions must be set.
It cannot be moved or dismantled, and must be inspected by the manufacturer at any time. Records are still kept in the machine tool, and production use is not allowed to be changed, otherwise the machine will automatically lock up.
Before Zhou Qingfeng did not have enough professionals. He couldn't install the CNC machine tool himself with the manual.
This high-tech gadget is not comparable to a 486 computer that can be used with electricity. It has requirements for the foundation, and absolute stability must be guaranteed, otherwise the accuracy will be affected.
Zhou Qingfeng wants to engage in technical training. Now that CAD has been done, let's also do CNC machine tools. Anyway, it is not him who has the headache to read the instructions.
The'industrial waste' shipped this time is a brand-name machine tool made in Jiangsu and Zhejiang. It's probably a product more than ten years later. It doesn't even have an operating system. It is controlled by the Z80's single-chip microcomputer.
This thing needs to be programmed on the computer, set the operation of the cutter and the motor, and then burn a memory chip into the single-chip circuit board of the machine tool.
Ordinary three-axis low-end products, the accuracy is not too high, there is nothing to say.
However, the two forklifts that came with him made Zhou Qingfeng even more happy. With a forklift, it is much easier to carry goods and the efficiency is greatly increased.
But in the eyes of the workers in the workshop, the CNC machine tools moved out with a forklift are different. Different from the rough shape of ordinary machine tools, this CNC gadget appears high-end in appearance.
Next to the foundry workshop is the machining workshop of "Shengguang Machinery". Master Niu from Magic City listened to the delivery of CNC machine tools and took the initiative to direct the unloading of light trucks.
"Oh, this machine is good. Advanced, advanced! Advanced than the ones I used in the Magic City Factory."
A circle of workers gathered around the truck to watch the excitement. Master Niu drove the crowd away and directed the forklift to move the machine tool into the workshop. The floor of the workshop has been re-cured to ensure that the installed machine tools are stable enough.
Master Niu drove people, but at the same time he yelled for science popularization with a smile, "The factory I used to spend spent a lot of foreign exchange on buying second-hand CNC machine tools from the United States.
But the Yankees cheated us. They sell very old products, and the program input actually uses punched paper tape. These shattered gadgets of what age are sold to us as treasures.
Later, the paper tape was scrapped, and no one understood the thing, and the million-dollar equipment was scrapped. What a pity. "
Watching the lively workers were ignorant and whispered. Many people feel that Master Niu is talking nonsense, how high-end the CNC machine tool is, how can it be controlled by paper tape
The two don't overlap.
Shumei Sophia has a special ability to'forge documents'. Master Niu is holding several machine control instructions with revised dates and other information in his hand, and he is extremely sure: "This must be a Japanese product."
Everyone was curious and asked why
"The Japanese want to make our money, they are still very careful. Only they can publish the Chinese manual. If it is German, you have to learn a German. Those Europeans are arrogant."
The operating instructions are thick and heavy, and contain a lot of data that outsiders can't understand.
Only Master Niu looked more and more happier, "Oh, what this Japanese does is meticulous, and the more I look at it, the more I feel that this manual seems to be written by a Chinese."
"Maybe it is our domestic product?" An apprentice probe asked next to him, "I think the nameplate on the machine is all Chinese characters."
Master Niu immediately shook his head, "Impossible, impossible, this kind of product is not available in China. This must be the imported goods smuggled in by Mr. Zhou. The Chinese characters may be used to cover people's eyes.
According to the book, the operation is very simple. Amazing, really amazing. Such good things can actually get in. With this CNC machine tool, we will save much trouble in the future. "
The installation of CNC machine tools requires professionals, who are usually sent by the original factory.
But where did Zhou Qingfeng come from the'original staff', he could only pick up 20 experienced people from the backbone he had recruited and gathered together, clutching the instructions and immersing himself in reading.
Svitch has been running around like a panacea these days. Because he knew both computers and machinery, he had just cleared out hundreds of 486s, and the task of networking was not completed, so he was sent to install CNC machine tools.
'Ordinary' three-axis linkage CNC machine tools, matching tools, fixtures, lubricating fluid, programming software and computers are available. Schweitzer was busy with the installation and debugging, and a call was made to his "big brother".
Or the classmate of Magic City who introduced the work, the god mysteriously asked: "Old Shi, I heard that you installed CNC machine tools for a private company in the "Holy Light"?"
Schweitzer is watching the instructions to learn the programming of the machine tool.
In fact, this is very simple. It is a series of command lines to set hundreds or thousands of parameters, telling the Z80 chip that controls the machine tool when to activate the stepper motor, what rotation speed of the spindle, how much angle the cutter head rotates, and how deep the cutting is.
Low-end CNC machine tools can't play any tricks either.
A classmate came to ask, and Old Shi answered, "Yes, I'm busy. The news spreads so quickly, the machine hasn't been debugged, how did you know?"
The classmate did not answer, but continued to ask: "What brand is the machine, what model, and what's the performance?"
"I don't know the brand and model. A master said it was a Japanese product, but I always felt something was wrong. What about the performance... The debugging hasn't been done yet, but according to the instructions, it is really good.
Small machine tools with three-axis linkage can deal with ordinary workpieces. I noticed that the semi-closed-loop servo mechanism can be used for surface processing.
The operation manual says that the accuracy is ten micrometers, but I don't know the specifics. This accuracy is not bad, and general needs can be met.
It is worth noting that the tool, the spindle speed is up to 15,000 in the operating instructions, and the cutting speed can be 60m/min. Then this tool is really powerful. "
Sevich said very carefully, and his classmates also listened quietly. After listening to the performance description, the other party asked, "Do you know how much foreign exchange you spend on buying each week?"
"He's smuggled goods."
"Smuggled goods don't need foreign exchange?"
That's right!
A question mark flashed in Swich's mind. This'Holy Light' Zhou always has too much capacity, how can he get any good things? I never saw him feel sad.
The classmates chatted for a long time, and finally asked, "Help Mr. Zhou, can he get a large-scale 5-axis CNC machine tool from abroad? The price is actually easy to say, as long as the stock is available."
With this question, Seviche understood.
