Chapter 444: CNC machine tools (1)

The development of machine tools from manual to numerically controlled has a production efficiency equal to the past ten.
Numerical control technology is free of human factors in terms of accuracy and adaptability, and is completely controlled by the computer, ensuring extremely high part consistency.
No matter what weird parts are processed, it is nothing more than a program control problem for the computer.
It used to be extremely difficult to process turbines and screws, requiring technicians with more than seven or eight years of experience to be competent.
Now as long as the machine has the corresponding capabilities, ordinary secondary school students who have been trained for several months can do it.
NC machine tools are so good, but in the 1990s, China basically relied on imports, such as Japan's FANUC.
People can still stand up to you and have many restrictions.
It cannot be moved or disassembled, and must be inspected by the manufacturer at any time. Records are also kept in the machine tool, and it is not allowed to change the production purpose, otherwise the machine locks automatically.
Before Zhou Qingfeng's men did not have enough professionals. It was impossible for him to hold the manual to install the CNC machine tool.
This high-tech gadget is no more than a 486 computer that can be used when powered on. It has requirements on the foundation, and must be absolutely stable, otherwise it will affect accuracy.
Zhou Qingfeng wants to engage in technology Now that cad is done, then CNC machine tools should also be engaged. It wasn't him who had a headache reading the instructions anyway.
The 'industrial waste' shipped this time is a miscellaneous machine tool made in Jiangsu and Zhejiang. It is a product about ten years later, even without an operating system, which is the single chip control of the z80.
This stuff needs to be programmed on a computer, set the operation of the cutter and motor, and then burn a memory chip and insert it into the single-chip computer circuit board of the machine tool.
Ordinary three-axis low-end products, the accuracy is not very high, there is nothing to say.
However, the two forklifts that came with it made Zhou Qingfeng even more happy. With a forklift, moving goods is much simpler and more efficient.
However, in the eyes of the workers in the workshop, the CNC machine tools moved by forklifts are different. Unlike the appearance of ordinary machine tools, this numerically-controlled gadget appears high-end in appearance.
Next to the foundry workshop is the machining workshop of ‘Shengguang Machinery’. Master Niu from Modu listened to the CNC machine tools and took the initiative to direct the unloading of light trucks.
"Oh, this machine is good. Advanced, advanced! It's more advanced than what I use at Modu."
Workers around the truck watched the crowd. Master Niu pushed the crowd away and instructed the forklift to move the machine into the workshop. The floor of the workshop has been re-solidified to ensure that the installed machine is sufficiently stable.
Master Niu was rushing to catch people, but at the same time, he was carrying out science popularization with a smile and smile. "The factory I used to spend a lot of foreign exchange on US used CNC machine tools.
But Yankees pit us and sell very old products. The program input actually uses punched paper tape. It's a scumbag of any age, and it was sold to us like a baby.
Later, the paper tape was used up, and no one understood the thing, and millions of devices were scrapped. What a pity. "
Seeing the incomprehension of the lively workers, talking verbally. Many people feel that Master Niu is talking nonsense. How high-end is the CNC machine tool, how can it be controlled by paper tape?
The two don't cross the border.
The book charm Sophia has a special ability is ‘forged documents’. Master Niu is holding a few machine tool instructions that have been modified with information such as dates. He is extremely certain:
This must be Japanese.

Everyone was curious and asked why?
"The Japanese want to make our money, they still have a very careful heart. Only they can produce manuals in Chinese. If it is German, you have to learn German. The Europeans can be arrogant."
The operating instructions are thick and heavy, and contain a lot of data that outsiders cannot understand.
Only Master Niu became more and more happy, "Oh, the Japanese are doing meticulous things, and the more I read, the more I feel that this manual is written by Chinese."
"Maybe it's our domestic product?" An apprentice probe asked next to him, "I see the nameplate on the machine is in Chinese characters."
Master Niu shook his head immediately, "Impossible, impossible, there is no such product in China. It must be imported goods smuggled by Mr. Zhou, and Chinese characters may be used to cover people's eyes.
According to the book, the operation is very simple. It's amazing, it's amazing. Such good things can come in. With this CNC machine tool, we will save a lot of trouble in the future. "
The installation of CNC machine tools requires professionals, and the original factory usually sends them.
But where is Zhou Qingfeng's "original staff", he can only choose twenty or so experienced from the backbone he has recruited to gather together and read the manual carefully.
Shiwei has been running around like 'Jing Jin You' these days. Because he knew both computers and machinery, he had just cleared out a few hundred 486s, and before he finished the networking task, he was sent to install a CNC machine tool.
'Ordinary' three-axis linkage CNC machine tools, supporting tools, fixtures, lubricants, programming software and computers are all available. Shi Wei is busy with installation and commissioning, a phone call to his 'brother'.
Or the classmate who introduced the work, God asked mysteriously, "Old history, I heard that you installed a CNC machine tool for a" Holy Light "private company?"
Shiwei is looking at the programming of explanatory machine tools.
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 move the stepper motor, what speed of the spindle, how many angles the cutter head rotates, and how deep the cutting is.
Even low-end CNC machine tools can't play tricks.
The classmate asked, Lao Shi answered, "Yeah, I'm busy. The news spreads fast, and the machine hasn't been debugged yet. How did you know?"
The classmates did not answer, but just continued to ask: "What brand, what model, and the performance are different?"
"I do n’t know the brand and model. A master said it was a Japanese product, but I always felt something wrong. Performance, debugging has not been done yet, but it is really good according to the operating instructions.
Small machine tools with three-axis linkage can deal with common workpieces. I noticed that the semi-closed-loop servo mechanism can process curved surfaces.
The operation manual says that the accuracy is ten micrometers, and the specifics are unknown. This accuracy is not bad, and general needs can be met.
It is worth noting that the spindle speed of the tool is up to 15,000 and the cutting speed can be 60m / min. Then this knife is really amazing. "
Shiwei talked very carefully, and his classmates listened quietly. After listening to the performance description, the other party asked, "Do you know how much foreign exchange do you always buy?"
"He's smuggling."
"Don't you exchange money for smuggled goods?"
That's right!
A question mark lighted up in Shiwei's mind. The Zhou of the "Holy Light" is always too patient. How can he get all the good things? I never saw him sad.
The classmates talked for a long time, and finally asked, "Help me, Mr. Zhou, can he get a five-axis linkage large-scale CNC machine tool abroad? In fact, the price is easy to say, as long as it is available."
With this question, Shiwei understood.
