The machine tool has developed from manual to numerical control, and the production efficiency of one machine is worth ten in the past.

CNC technology is free from the human factor in terms of accuracy and adaptability, and is completely controlled by the computer, which ensures a very high consistency of parts.

And no matter what odd-shaped parts are machined, it is nothing more than a matter of program control for the computer.

In the past, machining turbines and screws was an extremely difficult job, requiring a technician with more than seven or eight years of experience.

Now, as long as the machine has the corresponding ability, ordinary secondary school students with several months of training can do it.

CNC machine tools are so good, but the country basically relied on imports in the nineties, such as Japan's 'Fanuc'.

People still look up to you when they sell you, and they have to set a lot of restrictions.

It cannot be moved, cannot be disassembled, and must be inspected by the manufacturer at any time. Records are also kept in the machine, and it is not allowed to change the production purpose, otherwise the machine will automatically lock.

Before, Zhou Qingfeng did not have enough professionals. When he got a CNC machine tool, it was impossible for him to install it with the manual.

This kind of high-tech gadget is no better than a 486 computer that can be used with electricity. It has requirements for the foundation, and it must ensure absolute stability, otherwise the accuracy will be affected.

Zhou Qingfeng wants to engage in technology, since CAD is done, then CNC machine tools are also done. Anyway, it's not him who has a headache when reading the manual.

The 'industrial waste' transported this time is a miscellaneous machine tool made in Jiangsu and Zhejiang. It's probably a product more than ten years later, and it doesn't even have an operating system, which is the single-chip microcomputer control of Z80.

This thing needs to be programmed on the computer, set the operation of the tool and motor, and then burn a memory chip and insert it into the circuit board of the single-chip microcomputer of the machine tool.

Ordinary three-axis low-end products, the accuracy is not very high, there is nothing to say.

But the two forklifts that came with it made Zhou Qingfeng even happier. With forklifts, it is much easier to move goods and more efficient.

But in the eyes of the workers in the workshop, the CNC machine tools that are moved out with forklifts are different. Different from the appearance of crude benzene of ordinary machine tools, this CNC thing looks high-end in appearance.

Next to the foundry workshop is the machining workshop of 'Shengguang Machinery', and Master Niu from Modu listened to the CNC machine tools and took the initiative to command the unloading of light trucks.

"Oh, this machine is good. Advanced, advanced! It's more advanced than what I used in the Magic Capital Factory. ”

A circle of workers surrounded the truck to watch the excitement, and 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-cured to ensure that the installed machine was stable enough.

Master Niu drove people away, but at the same time shouted with a smile on his face, "The factory I used to stay in spent a lot of foreign exchange to buy second-hand CNC machine tools in the United States.

But the Yankees cheated us, selling very old products, and the program input actually had to use perforated paper tape. This is all a broken thing of what age, and it is sold to us like a baby.

Later, the paper tape was scrapped, no one understood it, and the million-dollar equipment was scrapped. It's a shame. ”

Watching the lively workers listen to the ignorance, and talk about it from ear to ear. Many people feel that Master Niu is talking nonsense, how high-end the CNC machine tool is, how can it be controlled with paper tape?

The two don't have a boundary.

Shumei Sophia has a special ability of 'forging documents', Master Niu held a few machine tool control instructions with modified dates and other information in his hand, and said with great certainty: "This must be a Japanese product." ”

The crowd was curious and asked why?

"The Japanese want to make our money, and they are very careful. Only they will produce instructions in Chinese. If it's German, you'll also have to learn German. Those Europeans are arrogant. ”

The operating instructions are thick and heavy, and they contain a lot of data that outsiders can't understand.

Only Master Niu was happier the more he watched, "Oh, this Japanese thing is meticulous, and the more I look at it, the more I feel that this manual seems to be written by Chinese." ”

"Maybe it's our domestic goods?" An apprentice probe 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 goods smuggled in by Mr. Zhou, and there are Chinese characters that may be used to cover people's ears and eyes.

According to the book, the operation is very simple. It's amazing, it's amazing. This kind of good stuff can actually get in. With this CNC machine, we will save a lot of trouble in the future. ”

The installation of CNC machine tools requires professionals, and the original factory generally sends people.

But where did Zhou Qingfeng get any 'original factory personnel', he could only pick about 20 experienced people from the backbone he recruited to get together, and read hard with the manual.

Shi Wei has been running around like a 'jack of all trades' these days. Because he understands both computers and machinery, he has just cleared out hundreds of 486s, and the task of networking has not been completed, so he was sent to install CNC machine tools.

'Ordinary' three-axis linkage CNC machine tools, supporting tools, fixtures, lubricating fluids, programming software and computers are available. Shi Wei was busy with the installation and commissioning with someone when a phone call came to his 'big brother'.

Or the Modu classmate who introduced the work, asked mysteriously: "Old Shi, I heard that you installed CNC machine tools for a 'Holy Light' private company?" ”

Schwich was looking at the programming of the illustrative machine.

In fact, this is very simple, that is, a series of command lines to set hundreds of parameters, telling the Z80 chip that controls the machine tool when to move the stepper motor, what spindle speed, how much angle the cutter head turns, and how deep the cut.

Low-grade CNC machine tools can't play any tricks.

When a classmate came to ask, Lao Shi answered, "Yes, I'm busy." The news spreads so fast, and the machine hasn't been debugged yet, how do you know? ”

The classmate didn't answer, but continued to ask: "What brand is the machine tool, what model, and what is the performance?" ”

"I don't know the brand or model, and one of the chefs said it was Japanese, but I always felt that something was wrong. The performance is ......, and the debugging hasn't been done yet, but according to the operating instructions, it's really good.

Three-axis linkage of small machine tools, ordinary workpieces can be dealt with. I noticed that the semi-closed-loop servo mechanism can be used for surface machining.

The operation manual says that the accuracy is ten microns, but the specific details are not known. This accuracy is not bad, and it can cope with general needs.

It is worth noting that the spindle speed is 15,000 and the cutting speed can be 60m/min. Then this knife is really powerful. ”

Shi Wei spoke very carefully, and his classmates listened quietly. After listening to the performance description, the other party asked, "Do you know how much foreign exchange you spend on every week?" ”

"He's smuggling."

"Don't you want foreign exchange for smuggled goods?"

That's right!

A question mark lit up in Swift's mind. This 'Holy Light' Zhou is too capable, how can he get any good things? I didn't see him sad.

The classmates chatted for a long time, and finally asked, "Help ask you Mr. Zhou, can he get a foreign five-axis linkage large CNC machine tool?" The price is actually easy to say, as long as it is in stock. ”

This question, Shi Wei understood.
