When NC apprentices have a task system

Chapter 18 Prelude Trilogy
"Ding! Dungeon NPC Deng Shan's basic exercise learning task completed: 50% progress, keep working hard!"

half?

Xu Yang knew that being familiar with the system operation panel did not mean that he had finished learning the basic operation process, because there were still three prelude steps for actual processing.

As soon as the words fell, Deng Shan continued:
"Xiao Xu, now I'm going to teach you the three steps of the prelude: clocking, minutes, and knife setting."

With that said, Deng Shan picked up a piece of leftover material.

"The machining of parts by CNC machining center is to level the workpiece first."

"My machine is a vertical machining center, so the calibration is installed vertically. It doesn't matter whether it is sucked on the protective cover of the spindle with a magnetic base or placed in the cutter head."

After finishing speaking, Deng Shan fixed the scraps with a yardstick.

In fact, Xu Yang did not dial the watch before operating the machine, because the master of Jingdiao Machine adopted the method of positioning pins to determine the horizontal and vertical of the machined parts in order to simplify the difficulty of operating the machine.

In addition, metering is all the prerequisites for CNC machining parts, so it can not be said to be the top priority.

Thinking of this, Xu Yang set his mind to observe and study with 12 points.

"Watching is a prerequisite for processing. Please read carefully and don't ask."

Deng Shan adsorbs the dial indicator on the spindle, and then touches the pointer to the workpiece.

Xu Yang found that at the beginning, when Deng Shan moved the dial indicator with the handwheel, the pointer of the dial indicator rotated counterclockwise twice and then stopped moving.

At this time, Deng Shan seemed to see Xu Yang's doubts, and continued:

"You can see that the dial indicator is directly on strike, which means that the workpiece I placed is slanted, and it is very slanted. Often this is the meaning of our dialing."

"Of course I'm deliberately teaching you how to play the watch. Otherwise, I can arrange the watch horizontally and vertically in advance to shorten the time for playing the watch, but these are not important."

After speaking, Deng Shan began to move the dial indicator.

"I choose the reference value of the dial indicator as 20, and then move the dial indicator to the right of the X-axis. If the value becomes larger, it means that the right side is higher. At this time, you only need to take the copper rod to hit the right side, and move back and forth repeatedly. X-axis, until the value of the workpiece surface swings 15-20, or 20-25. The error of five wires is acceptable. Of course, this is not absolute. If it is a high-precision mold part, the value of the swing cannot exceed one wire .”

Xu Yang read it once, and to be honest, he only understood a general idea.

Then Deng Shan demonstrated again how to make minutes.

If playing a watch is a leveling workpiece, then the minute is to find the center.

In CNC machining, sub-center rods are generally used. Of course, most hardware factories and small workshops use knives instead.

Deng Shan uses a 6mm milling cutter instead of a centering rod.

Xu Yang discovered that Deng Shan had dyed the handle of the knife red with a red pen. Is it for the purpose of scoring?
Sure enough, at this time Deng Shan turned around and said:

"Xiao Xu, do you know why I am superfluous?"

"Could it be for the center?" Xu Yang guessed.

He knew that a master in the mold industry would definitely not do meaningless things. Since he did it, it must be for processing needs.

Deng Shan showed approval and said:
"Ruzi can be taught!"

"That's right, coloring the scoring stick is just to score faster."

Look good!
After speaking, Deng Shan turned on the spindle speed.

The principle of centering is to find the center of the workpiece, so the most direct way is to touch the four sides.

First touch the X-axis of the workpiece, move the X-axis quickly until it is close to the side of the workpiece, slow down the speed, and then continue to move the X-axis in the manual mode. If the swing of the split rod becomes smaller, then it can only be adjusted to the lowest speed of the manual. Tap a few times, once the center stick is off (or the workpiece is stained red), this is the best effect-the X-axis value returns to zero.

Lift the workpiece after returning to zero, move directly and quickly to the other side of the X-axis of the workpiece, and then meet.At this time, instead of returning to zero, press the 1/2 key, and the center of the X axis will be found.

The same is true for the Y axis.

After finishing the division, there is only the final stage of the prelude trilogy—knife setting.

"Xiao Xu, how did you fight swords before?"

Deng Shan looked at Xu Yang and asked.

"Facing the knife directly at the workpiece." Xu Yang blurted out.

"Ha ha!"

Deng Shan heard the words and said with a smile:

"Well, you're doing it the old way."

"There are several types of tool setting in our machining center. The first one is to touch the surface of the workpiece, which is also an old routine."

"But I want to tell you, that is actually a non-standard tool setting method. If it is a high-precision mold, it will be miserable. The tolerance must not be up to standard."

"Why?" Xu Yang was taken aback.

Deng Shan glanced at Xu Yang, and continued:

"why?"

"High-precision mold processing is not about making a test frame, let alone drilling and milling a slot, but a design concept with high standards and strict requirements, so professional equipment is needed here-infrared tool setting instrument"

Infrared tool setting instrument?
This is the first time Xu Yang heard that there is special equipment for knife setting. It seems that the water in the mold industry is still too deep, comparable to the Pacific Ocean!
Next, Xu Yang can be said to be an eye-opener. With the automatic knife setting instrument, the speed is simply too fast.

So far, the prelude trilogy teaching has been completed!
"Ding! Dungeon NPC Deng Shan's learning task is completed: Money +400! Experience +400! Operating experience +400! Deng Shan's CNC machining experience. Congratulations to the host for getting the title-handy!"

yeah!
The task is completed, and there are many rewards.

But the title "handy?"

For this title, Xu Yang was puzzled.

"Ding! The title is an auxiliary function. After the host wears the title, it will have a special boost effect for the prelude trilogy."

"!!!"

"Isn't it?"

After some shock, Xu Yang quickly calmed down.

great!
Xu Yang's CNC machining center has just started and is in an extremely jerky state. It can be said that he dares to see but dare not do it.

it's good now.

With the boosting effect of the title of Handy, Xu Yang's hands-on ability has directly developed by leaps and bounds, and he bid farewell to the entry mode.

Just when Xu Yang was feeling happy, Xu Hui came over, looked at Xu Yang's smirk, frowned and said:
"Xiao Xu, why are you in a daze?"

Xu Yang was taken aback when he heard the words. He was familiar with Xu Hui's temper, so he naturally saw Xu Hui's displeasure.Oh, hurriedly smiled:
“Mr. Deng’s teaching was so wonderful, I was so fascinated!”

"Humph!"

Xu Hui snorted coldly, then continued to Deng Shan:

"Old Deng, I have changed the procedure for pressing the head, do you want to try it?"

"Well, it's up to you."

Deng Shan smiled slightly.

"XCMG is mighty!"

Seeing this, Xu Yang immediately stepped forward and gave a thumbs up to ease the embarrassment just now.

Hey!
As an apprentice, in order to learn technology, either to please the master, or on the way to please the master.

Wear a thousand clothes, don't flatter yourself!
At this moment, Xu Yang noticed the corners of Xu Hui's mouth rising slightly, and suddenly thought inwardly:
"not good!"

Sure enough, Xu Hui asked:
"Old Deng, how is Xiao Xu learning? Have you ever practiced the prelude trilogy?"

Deng Shan was taken aback: "Not yet."

"That's good!"

After finishing speaking, Xu Hui turned around to greet Xu Yang and said:
"Xiao Xu, since you were fascinated by listening to it just now, it means that you have studied well, so you will set up this Saigang, the prelude trilogy?"

　Rejuvenating the country through industry, CNC technology!
