So Qin Tian successfully obtained a pass to enter the shipyard...... Due to the trade secrets involved, bodyguards, mercenaries, and the like are generally not allowed to enter the shipyard unless necessary.

At this time, of course, Qin Tian didn't have this problem, so he ran to the shipyard when he had time to discuss some problems in the reinforcement and transformation with White...... These problems were actually intentionally left by Qin Tian, and the quantum chip could be calculated in one step.

However, of course, Qin Tian would not be stupid enough to do this, this is because the overly perfect design will make people suspicious, and on the other hand, Qin Tian deliberately delays time to allow himself to have more opportunities to enter and exit the shipyard.

Qin Tian came into contact with CNC machine tools on the third day.

"Hey!" On this day, Qin Tian took the drawing and said to White: "We need to be careful in processing this connecting part, if the size is not right, it is easy to deform!" ”

Some connecting parts connect pressures from several directions and cancel each other out, and a slight error may lead to uneven force and eventually failure.

"It's not a big deal, Qin!" White said with some pride: "We have CNC machines!" ”

So Qin Tian stood in front of the CNC machine tool.

White didn't realize that this was Qin Tian's main purpose, and he introduced to Qin Tian with great interest: "DMG1390, five-axis linkage, you just need to enter its specifications and dimensions here......"

With that, White entered data into the DNC (Direct Numerical Control).

Qin Tian looked around at this CNC machine tool, the so-called five-axis linkage refers to three Cartesian coordinate axes and two rotary coordinate axes, simply put, it can turn the parts upside down and process freely and quickly and accurately.

In this regard, Western countries have been implementing a technical blockade on Huaxia, and not long ago produced their own machine tools, but there is still a big gap between the technical level and the DMG series in front of them.

"Oh, you're probably familiar with it...... right," White asked, looking up.

"No, White!" Qin Tian replied: "This is the first time I've seen a CNC machine, I've only heard of it before!" ”

"Really?" White laughed happily: "Then you can open your eyes!" ”

As he spoke, White beckoned to Qin Tian and motioned for Qin Tian to follow him.

Walking a few dozen meters down the iron corridor to the side, and then climbing a few more steps, White raised his head downward and said, "Look at this, DMG5380, we have three of these things!" ”

Qin Tian stepped forward and took a look, what a big guy...... The size of two basketball courts, like a steel giant, with a giant propeller lying flat on the rotating shaft in the middle, and a robotic arm cutting it quickly and precisely according to the data.

"50 meters long and weighs 1,450 tons!" "It used to make a propeller that weighed 106.3 tons and was 9.1 meters in diameter!" White said. ”

As mentioned before, the production of propeller requires precision, otherwise it will produce a large number of cavitations when it runs at high speed in seawater, and as a result, the propeller will vibrate violently, make noise, depress the rotational speed and use power, etc.

To put it simply, the "vacuole phenomenon" will not only shorten the life of the propeller itself, but also greatly reduce the sailing speed of the hull.

(Note: The "Brave", which discovered the "cavitation phenomenon", was originally designed to have a speed of 27 knots, but the actual speed was only 24 knots)

This is one of the reasons why the spiral pulp needs to be polished by CNC machine tools: manual grinding cannot have the accuracy of CNC machine tools. Among them, especially military ships, the most demanding is the submarine, because it needs to sail quietly underwater, and the "cavitation phenomenon" of the propeller creates a lot of noise.

"What about precision?" Qin Tian asked casually, in fact, he didn't need to ask at all, he just did this to make himself behave "normal".

"0.008 mm!" White replied, "About a tenth of a hair!" ”

"Unbelievable!" Qin Tian sighed.

After a pause, he asked, "Can it make anything other than building a spiral?" ”

"Of course!" White replied, "Pretty much any part you can think of, you just have to enter the drawings and it will do the rest!" ”

Qin Tian nodded, this was exactly what he needed...... It can be used to build a whole production line, or use it to build machine tools, and then you can produce what you need as you like, and Qin Tian was a little nervous when he thought of this.

However, at this time, Qin Tian could only look at it, and at the same time sighed in his heart: "Hunting" is sitting on the world's largest wealth and only using it to build cargo ships.

At this time, the phone rang, and Qin Tian picked up the phone, and the secretary's voice came from the other end: "Assignment task, ten minutes to the company's gate!" ”

"Okay!" Qin Tian replied.

Originally, Qin Tian thought that this mission was still going forward and following a large group of people as before, but to his surprise, when he arrived at the gate of the company, there was no one.

When Qin Tian was looking around, a pickup truck stopped in front of Qin Tian, and Kelly rolled down the window and beckoned to Qin Tian inside, shouting, "Get in the car!" ”

Sitting in the passenger cab, Qin Tian asked suspiciously, "No one else?" ”

"You want someone else?" Kelly asked rhetorically.

Qin Tian couldn't help but be stunned when he heard this, and then replied: "No, of course not!" ”

Kelly laughed and continued, "With you, you don't need anyone else, do you?" ”

"Maybe!"

"Maybe what does that mean?"

"Maybe it means I'm a human being, Kelly!" Qin Tian replied: "I also have things that I can't control!" ”

"Interesting!" Kelly smiled and shook her head.

"What's interesting?"

"You and Steve seem to be opposites!" Kelly replied, "He always thinks that everything is under his control, and you ...... With such strength, I always think that I am not strong enough. Are you sarcastic about me? Or us? ”

"What?" Qin Tian couldn't keep up with Kelly's rhythm.

"If you're not strong enough, what are we?" Kelly said with some excitement: "We need the protection of others, we need to bring a lot of people with us when we go out at any time in this ghost place, and even then we have to worry about whether there are moles in the people we bring, and we don't even know if it's us who lives...... Tell me, Qin, who the hell are you? What are you afraid of? ”

"I am who I am!" Qin Tian cast his gaze out the window and avoided Kelly's gaze: "I'm not afraid of anything!" ”

Of course, Qin Tian's words were not true, and at the same time, she was secretly shocked, although Kelly didn't know anything, her feeling was like a quantum chip that could analyze and find something right from the subtleties.

If there's anything humans can compare to computers, it's probably this.
