"Do you know how to mill propellers?"
"No factory in Zhongyun dares to boast that they can mill propellers, not even Huaxing Heavy Industry!"
"You definitely don't know what complex surface processing is, and you also don't know that if you want to mill propellers with a 5-axis machining center, you have to redesign it."
"High speed propellers require high precision from the seven blades, and you definitely don't know either. Normal 5-axis machines can only use ball end milling tools to cut these complex surfaces. "
"Ball end milling tools have zero linear speed in the center of the milling tool, so tell me, how do you guarantee precision?"
"You don't know anything, and you just want us to mill propellers?"
The foreman was both angry and amused, and blabbered a bunch of nonsense.
Several workers next to him also explained to Ye Qing, saying that without a professional 5-axis machine, it was no doubt a joke to want to process a qualified seven blade propellers.
It was guaranteed that after a few nautical miles, the propellers would break due to uneven forces.
"Haha ~ look at you pretending to know when you don't know, you really make me laugh to death, what CNC machining center." The young man who just jumped into the water to take pictures, perhaps because he wanted to show more of his face in front of the beauty. They simply treated Ye Qing, who was dressed in famous brands and looked very elegant, as an enemy.
Xia Muqing naturally stood on Ye Qing's side, not to mention that the two were business partners, just based on the fact that Ye Qing saved her once before, she had to stand on Ye Qing's side without reservation.
"If you can't process it, then you can't process it. What do you mean by laughing at others?" Xia Muqing's face was cold as she angrily stared at these people.
"Okay okay, stop laughing, hurry up and get to work." The foreman loudly scolded, but in the end, he couldn't hold his expression for more than three seconds before he couldn't help but laugh again.
"If you can't mill it, it's your technical problem."
Ye Qing didn't get angry, and smiled at Xia Muqing: "If the propellers are so difficult to process, then let me ask you, how much does it cost to import a pair of propellers?"
"It's not expensive. It's only 24,000 to import a pair of seven fan leaves. There are some professional factories in China that can do it, but the precision is a bit lacking. "The foreman knew that Ye Qing wasn't short on money, and that watch in his hand could probably be exchanged for a lot of propellers.
However, this did not mean that the shipbuilding factory's technology was not good enough.
"Such a cheap price. But you can't make it. If it's not a technical problem, then what is it? "
The foreman laughed disdainfully. "If you have the ability, then go ahead and build it. I'll give you one year. I'll give you one hundred thousand."
"I'll pay one million!" A worker who was tying a rope to the yacht and preparing to pull the yacht away from the dock interrupted.
Ye Qing sighed and turned to walk into the factory yard.
Xia Muqing quickly caught up with him and tried to persuade him. "Boss Ye, don't be angry."
"No?" Ye Qing was really not angry.
"Then you …" Xia Muqing thought that Ye Qing must be furious and didn't want to stay at the pier any longer.
"I'll make the propellers." Ye Qing smiled at her.
"What … did you say?" Xia Muqing looked as if she had seen a ghost. Although Tiancheng Mining Group didn't have a processing center, there were mountains of machine tools and machines. It wouldn't be a problem to cover the entire Dragon Creek Beach.
Xia Muqing naturally had some understanding of machine tools, so she was very surprised and thought that Ye Qing was talking nonsense.
"Brother Di, even if you're angry, you don't have to gamble like this." If the two of them were familiar with each other, Xia Muqing would definitely touch Ye Qing's forehead to see if he had a fever.
"Aren't propellers only made by a professional propeller factory? You definitely know that there are specialists in the industry."
"I know." Ye Qing pretended to be very depressed.
"But …"
"But I don't know why, but when I saw you at the pier just now and heard that it would take a week to fix, you were very disappointed."
"I … I was also very sad."
"So … I want to hand-make a pair of propellers for you!"
At this time, Xia Muqing didn't look like she had seen a ghost. Instead, she looked like she had seen an angel kissing a devil.
"Haha …" Ye Qing saw her incredulous look and couldn't continue acting. He held his stomach and laughed loudly.
He wanted to make propellers purely because he didn't want the yacht to stay here for too long. In addition, the production workshop just happened to have suitable materials for making propellers.
The most common materials for civilian propellers were copper alloy, aluminum alloy, and stainless steel. Ordinary metal materials were easy to rust and corrode.
There was a large pile of aluminum alloy in the workshop, and the thickness was even better. It was enough to make seven-bladed propellers.
The fewer the propellers' blades, the greater the curvature of each blade, and the thicker the material needed.
On the contrary, the more blades there were, the less material needed. However, the curvature of the blades was very large, and some could even be bent into the shape of a fish hook. The aluminum alloy plates Ye Qing bought were completely thick enough.
Moreover, civilian propellers didn't have as stringent quality requirements as military propellers. There was no need for any heat treatment at all. They could be used directly after processing. Those who pursued quality only needed to apply a layer of anticorrosive protective paint.
"You … you …" Xia Muqing knew that Ye Qing was joking with her, but she still blushed and felt very shy.
Of course, this didn't mean that Xia Muqing liked Ye Qing. Xia Muqing had seen all kinds of outstanding men. She was blushing purely because she was shy.
"Then why don't you go?" Xia Muqing, who finally reacted, found it funny. She didn't believe that Ye Qing could make high-speed propellers.
Ye Qing went to the office first, and Xia Muqing followed him in to see what this guy was up to. In the end, she found Ye Qing sitting at his desk and playing with the computer.
"Remember to inform me when you're done." Xia Muqing stretched her soft waist and winked at Ye Qing. "I'm going to the yacht to catch up on my sleep. I'll wait for your gift."
"No problem!" Ye Qing snapped his fingers.
To make propellers, he naturally needed the propellers' blueprints.
Ye Qing first logged onto the Sunbird Yacht Manufacturing Company's official website, but he couldn't find the detailed specifications of the propellers. He directly used QQ to contact customer service and said that he wanted to order a yacht, the model at the dock.
Customer service quickly sent over a bunch of information, including the detailed dimensions of the propellers. The manufacturer was also praised in text, and it was emphasized that it was made in Germany several times.
After memorizing the model, Ye Qing searched for the CAD and CNC blueprints of the propellers.
The information on civilian propellers was very open source, and there was a lot of it online. Especially on the domestic Internet, Ye Qing even found a few blueprints that were claimed to be the propellers of nuclear submarines.
Soon, Ye Qing found the exact same CAD blueprints of the propellers at the dock and downloaded them into a USB flash drive.
This process only took a little over ten minutes. Xia Muqing went back to the yacht to catch up on her sleep, and it just so happened that no one came to disturb Ye Qing.
After closing the door of the production workshop, Ye Qing directly summoned two master artisans.
They were born with processing precision + 8%, processing efficiency + 8%, and the binding precision + 2% of the second-level factory. It could be said that in terms of processing precision, no worker in the world could compare to the skills of a master artisan.
Two square aluminum alloy plates were quickly cut out, and the plates were placed on the completely black technology rapid metal engraving machine for personal use.
The rapid metal engraving machine was completely overkill for engraving stone.
Carving soft metals like gold, silver, copper, aluminum, lead, and so on was its specialty.
Because aluminum alloy was much tougher than stone, the speed of the engraving machine was a bit slower.
From time to time, Ye Qing would look to see if anyone came to spy. About twenty minutes later, the two propellers' embryos were freshly produced.
There were two CNC machining centers in the workshop, and the two propellers were processed together. First, the holes were drilled, and then the threads were tapped.
Finally, the finishing process was done by two master artisans who could be called human flesh machines. They directly used a polishing machine and two thousand mesh fine sandpaper to polish the propellers.
Ye Qing went out for a walk, and the shipyard workers worked for half a day before they finally towed the yacht to the beach in front of the dock.
At this time, the sea had not yet risen, so naturally, there was no way for the yacht to sit on the beach. They could only tie a rope to fix the yacht.
After returning to the office, Ye Qing deliberately dawdled for a while, then got up and went to the production workshop.
The two long completed seven-fan high-speed propellers were already lying quietly on the ground, emitting a silver-white light.
Perfect!
Perfect to the point of impeccable. Even the most picky engineer would not be able to find a single flaw.
The limit of the human eye's discrimination was 0.1 millimeters.
Experienced fitters, hand-made tools, could control the accuracy to 0.03 millimeters.
Then the question was … …
What about non-humans?
The master artisans were nothing special, but the system introduced that they were very good at processing precision parts.
Then there was the attribute of + 8% precision, the monster factory also had a 2% precision, and a 2% lifespan bonus.
These added together gave the master artisans the ability to be proud of the world's veteran fitters.
So the two propellers on the ground were first carved into the embryos by the black technology rapid metal engraving machine, and then after the master artisans hand-polished and controlled the precision, they directly had the qualifications to look down on the original factory's precision.
Even if it was Germany's Fort McClendon, the company specializing in the production of the yacht's propellers at the dock. Their top engineers came to compete with the master artisans on the precision of manual processing. Their wife, son, and mistress, all of them would lose, and they would not win.
When the level three monster factory came out, maybe they could take this group of master artisans to the major high precision processing plants to show off!
