Machine tools have evolved from manual to CNC, and the production efficiency of one machine is equivalent to ten machines in the past.
CNC technology gets rid of the human factor in terms of accuracy and adaptability, and is completely controlled by computers, ensuring extremely high parts consistency.
No matter what weird-shaped parts are processed, it is nothing more than a program control problem for the computer.
In the past, processing turbines and screws was extremely difficult work, 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 technical secondary school students with a few months of training can do it.
CNC machine tools are so good, but China basically relied on imports in the 1990s, such as Japan's 'FANUC'.
People still think highly of you when selling to you, and they have to set many restrictions.
It cannot be moved or dismantled, and it must be inspected by the manufacturer at any time. Records are also kept in the machine tool, and the production purpose is not allowed to be changed, otherwise the machine will automatically lock.
Zhou Qingfeng didn't have enough professionals at his disposal before. Even if he got a CNC machine tool, he couldn't install it himself with the instructions.
This high-tech gadget is no better than the 486 computer that can be used with electricity. It has requirements for the foundation and must be absolutely stable, otherwise the accuracy will be affected.
Zhou Qingfeng wants to engage in technical research. Since he has already done CAD, he should also do CNC machine tools. Anyway, he is not the one who has a headache after reading the manual.
The 'industrial waste' shipped this time is a miscellaneous machine tool made in Jiangsu and Zhejiang. It is a product that was probably produced more than ten years ago. It does not even have an operating system, it is controlled by a Z80 microcontroller.
This thing requires programming on the computer, setting the operation of the tool and motor, and then burning a memory chip and inserting it into the microcontroller circuit board of the machine tool.
The accuracy of ordinary low-end three-axis products is not very high, so there is nothing to say about it.
However, the two forklifts that came with it made Zhou Qingfeng even more happy. With forklifts, it is much easier to transport goods and the efficiency is greatly increased.
But in the eyes of the workers in the workshop, the CNC machine tools moved out with forklifts are different. Different from the rough appearance of ordinary machine tools, this CNC machine looks high-end in appearance.
Next to the casting workshop is the machining workshop of 'Shengguang Machinery'. Master Niu from Shanghai listened to the CNC machine tools being delivered and took the initiative to direct the light trucks to unload.
"Oh, this machine tool is great. Advanced, advanced! It's more advanced than the one 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 was re-solidified to ensure that the installed machine tool was stable enough.
While driving people away, Master Niu also shouted about popular science with a smile on his face, "The factory where I used to work spent a lot of foreign exchange to buy second-hand CNC machine tools from the United States.
But the Yankees deceived us by selling a very old product, and they actually required punched paper tape for program input. These were junk items from some era, and they were sold to us as if they were treasures.
Later, the paper tape was used up, no one understood what it was, and the equipment worth millions was scrapped. What a pity."
The workers who were watching the excitement listened in confusion and whispered among themselves. Many people felt that Master Niu was talking nonsense. The CNC machine tool was so high-end, how could it be controlled by paper tape?
There is no boundary between the two.
The book charm Sophia has a special ability of 'forging documents'. Master Niu held in his hand several machine tool operating instructions with modified dates and other information, and said with absolute certainty: "This must be Japanese goods."
People were curious and asked why?
"The Japanese want to make money from us, and they are very careful. Only they can issue instructions in Chinese. If it is a German product, you have to learn German. Those Europeans are so arrogant."
The operating instructions are thick and heavy, and contain a lot of data that outsiders cannot understand.
Only Master Niu became happier the more he looked at it, "Oh, the Japanese are so meticulous in their work. The more I looked at it, the more I felt that this manual looked like it was written by a Chinese."
"Maybe it's a domestic product?" An apprentice next to him asked, "I see that the nameplates on the machine are all Chinese characters."
Master Niu immediately shook his head, "Impossible, impossible, there is no such product in China. This must be an imported product smuggled in by Mr. Zhou. The Chinese characters may be to cover up people's ears.
According to what this book says, the operation is very simple. It's amazing, it's amazing. Such a good thing can actually be obtained. With this CNC machine tool, we will save a lot of trouble in the future."
The installation of CNC machine tools requires professionals, usually sent by the original factory.
But Zhou Qingfeng didn't have any "original factory personnel". He could only select about twenty experienced people from the backbone he recruited and gathered together, grabbing the manual and immersed themselves in reading.
Schweic has been running around like a 'taiwan oil' these days. Because he understands both computers and mechanics, he has just cleaned up hundreds of 486s. Before the networking task was completed, he was sent to install CNC machine tools.
An 'ordinary' three-axis CNC machine tool comes with supporting tools, fixtures, lubricants, programming software and computers. Schweic was leading people busy with installation and debugging when a call came to his 'big brother'.
It was the classmate from Modu who introduced the job and asked mysteriously: "Old Shi, I heard that you installed CNC machine tools for some kind of 'Holy Light' private company?"
Schwitch was looking at the programming of the illustrative machine tool.
In fact, this is very simple. It is a series of command lines that set hundreds or thousands of parameters to tell the Z80 chip that controls the machine tool when to move the stepper motor, what rotation speed the spindle should have, how much the angle of the cutter head should turn, and how deep the cutting should be.
Even low-end CNC machine tools can't do any tricks.
A classmate came to ask, and Lao Shi responded, "Yes, I'm busy right now. The news spread so fast. The machine hasn't been debugged yet. How did you know about it?"
The classmate did not answer, but continued to ask: "What brand and model is the machine tool, and what is its performance?"
"I don't recognize the brand and model. A master said it was made in Japan, but I always felt something was wrong. As for the performance... I haven't finished debugging it yet, but according to the operating instructions, it is really good.
Small machine tools with three-axis linkage can handle ordinary workpieces. I noticed that the semi-closed-loop servo mechanism can process curved surfaces.
The operation manual mentions that the accuracy is ten microns, but I don’t know the specifics yet. This accuracy is not bad and can meet general needs.
It is worth noting that the tool, according to the operating instructions, the spindle speed reaches 15,000, and the cutting speed can reach 60m/min. Then this tool is really powerful."
Shiwei spoke in detail, and his classmates also listened quietly. After listening to the performance description, the other party asked, "Do you know how much foreign exchange Mr. Zhou spent to buy it?"
"He is smuggled goods."
“Don’t smuggled goods require foreign exchange?”
That’s right!
A question mark lit up in Schweic's mind. This 'Holy Light' President Zhou is also very capable. How come he can get all the good things? I never saw him having trouble.
The classmate chatted for a long time and finally asked, "Help ask Mr. Zhou if he can get a large five-axis CNC machine tool from abroad? The price is actually easy to say, as long as it is in stock."
