It is not difficult to advertise in the evening newspaper, and when he takes out his business license, tax registration certificate, etc., takes out his ID card, and adds enough money, the other party will help him write an advertisement, and write his recruitment requirements and related benefits.

This time he recruited CNC machining workers, administrative personnel and salesmen, the basic salary is 3,000 yuan, the bonus is added according to the size of the contribution, the worker can be rewarded according to the number of processing, the salesman is rewarded according to the business commission, and the executive is rewarded according to the company's profit increase rate.

After the registration of the recruitment advertisement in the evening newspaper business department, Peng Huading went to the electromechanical market to purchase metal materials.

Because the workpieces processed by Yuejiang Shipping Company are basically ordinary No. 45 steel, and the stores that sell metal profiles have this kind of steel and steel ingots, Peng Huading has no instruments and equipment at hand, and it is not difficult to see the quality of these No. 45 with his eyes for a while, so he has to bargain with the store on the price, after knowing that the price of a certain brand of steel ingots is higher, he will go to another store to inquire and bargain, if the price of the same brand of steel ingots is still higher, he will determine that the quality of this brand of steel ingots is better, Just buy this brand.

After all, in the same situation, the quality of goods with high prices is slightly more reliable.

To be on the safe side, he started by buying only 100,000 yuan of ingots, and told the shop that if he had good quality and a fair price, he would come here again.

100,000 yuan is indeed not much in a large enterprise, but for a person like Peng Huading who comes to inspect the door, he buys 100,000 yuan at once, which is a big move. The owner of the store was alarmed, and automatically offered to cut and deliver it to Peng Huading.

This saved Peng Huading a lot of trouble. He also knew that this was the store that wanted to make friends with him, and also wanted to know the strength of Peng Huading's Yunfeng Technology Company, if Yunfeng Technology Company had a lot of demand for metal materials, they would definitely want to hug Peng Huading's thighs.

It's hard to do business right now.

Peng Huading paid a deposit of 50,000 yuan to the store, and after telling the other party the address of his company, he took the receipt given by the store and returned to the company.

Now he has to program the relevant programming on the CNC machining center according to the drawings provided by Liu Yangjun and write the machining program of the workpiece.

Peng Huading has a high level of mechanical and electrical knowledge, including CNC technology. For this kind of simple workpiece, it is not difficult to make up relevant excellent programs, the only thing that is a little tricky is that he is not very familiar with the current CNC machine tools, and the relevant instructions have to be learned one by one. In his opinion, the current CNC machine tools are still outdated, and the unit distance of each feed is still too large, that is, each feed processing is very "rough". Naturally, it is difficult to process a very precise workpiece.

He really wanted to make some improvements to the CNC machine, but unfortunately he didn't have the time or money to make these improvements right now.

If you really want to improve the CNC machine tool, you must not only improve the control system of the machine tool, but also improve the lead screw, subbox, gearbox and servo system of the machine tool. It is also necessary to update the more advanced stepper motor, to reinforce the overall shell of the machine tool, and to add several axes with several degrees of freedom......

To improve a backward CNC machine tool into an advanced CNC machine tool, its pay will not be a new machine tool simple, or even more processes. More constrained.

He said to himself: "Let's wait, wait until my company grows up." If you have money in hand and more technicians in the company, you will open a new CNC machine tool, so that not only will you be very relaxed, but others will not suspect anything. ”

In addition to programming the workpiece on the CNC machine, he also had to build a computer model on his self-assembled equipment and design the envelope of the workpiece on the computer.

Whether it is the "workpiece surface etching system" he assembles, or the "workpiece surface compensation system", there is a knife tip like a turning tool, which is defined as a probe, which will run its own trajectory in strict accordance with the computer's control, and encounters an excess part of the workpiece "intrusion" into the trajectory it runs, and the probe of the "workpiece surface etching system" will weld off the "invasive" part with a laser, and if the workpiece is smaller than the standard size, far away from the running track of the probe, the "workpiece surface compensation system" The probe then allows the surrounding metal ion solution to form an alloy layer on the surface of the workpiece.

As long as the reader with a little knowledge of machining can imagine, in order to "workpiece surface etching system" and "workpiece surface compensation system" of the probe wave, the operator must design a set of envelope for the workpiece in advance, that is, the theoretical space range of the workpiece, out of the envelope of the workpiece part to be eliminated, and less than the envelope of the workpiece part to be compensated, only the work is completely except in the envelope, no more, no less, that is the most standard workpiece.

The design of the envelope on the computer is sometimes very simple, such as a standard round bar, a few words of the source program can solve the problem, as long as the coordinate origin, radius, length, the number of the envelope jù model can be completed. For example, the standard cube is also simple, that is, the origin and the edge length.

However, it is not possible to be so simple for commonly used workpieces, especially for those workpieces with twisted surfaces, it takes a lot of time to design an envelope that meets the requirements, sometimes even several days, and many tests and modifications are required to meet the requirements.

He first wrote the CNC program, which was written while reading the manual of the CNC machine tool and looking at the instruction book about programming.

By the time the ingot seller sent the ingots to the company, he had already programmed the processing of the two workpieces.

The delivery store can be said to be full of hope, but when he saw that Yunfeng Technology Company was deserted, except that the boss was an old man guarding the door, he couldn't help but feel cold.

After unloading the goods, the store and the driver forced a smile on their faces and left.

Peng Huading didn't have any embarrassed expression, and after sending them away, he began to prepare to start the machining center and began to try to produce the workpieces that he had already programmed.

After nearly an hour of preparation, such as installing the tool, preparing the coolant, and moving the ingot cut by the store to the cutting table for reinforcement, etc., the processing is carried out.

I have to say that Peng Huading's technology is excellent, and the quality of the machining center sold to him by Zhang Jianxun is also good, plus the relatively simple parts he deliberately selected, so the processed workpieces are qualified after measurement.

Peng Huading did not stop there, he took the two workpieces processed by the machining center to another secret studio, which was equipped with the workpiece precision repair system he assembled.

He first measured the two workpieces with the precision measuring system here, saved the number jù in the zài computer, then installed one of the workpieces in the "workpiece surface compensation system", first took the time to design its envelope according to the design drawings of the workpiece, built the number jù model, and then used the "workpiece surface compensation system" to compensate for the part that had been overcut during the machining process.

After the workpiece was taken out of the "workpiece surface compensation system", he measured the workpiece, and now the compensation has achieved obvious results, the dimensional error is greatly reduced, and the original over-cut part has been well compensated, and the part that has not been over-cut has not increased before.

And the mechanical properties of those compensated parts fully meet the requirements.

Next, he reinstalled the workpiece in the "workpiece surface etching system", shared the model of the number of workpieces he had just built, and then burned and etched the excess part of the workpiece with a laser......

After the completion of the workpiece, he made a comprehensive measurement of the workpiece, and was pleased to find that the accuracy of the workpiece has increased from the original IT7 to IT6! In particular, the concentricity of the cylindrical part is significantly improved.

IT6 is already a very good accuracy, even the general machine tool spindle, bearings and other only need this level.

IT7 is often used in civilian products with higher precision, and the accuracy required by the parts of Yuejiang Shipping Company is almost all of this level, of course, there are some parts that belong to the level of IT8.

IT8 is medium precision and is widely used in agricultural machinery, textile machinery, printing and dyeing machinery, bicycles, sewing machines, medical equipment and other parts.

Seeing that his efforts had obvious results, Peng Huading was very excited: "Hehe, as long as the precision repair system is improved, won't it be easy to improve the accuracy of the workpiece to IT5 or even IT4 in the future?" That's great! ”

Originally, he was going to continue the repair of the second workpiece, but he received a call from Xue Dashan in the communication room: "There is a girl who claims to be named Guo Yi and has come over with two beautiful girls to visit the company." ”

He had no choice but to put down the work in his hand, carried two workpieces out of the secret studio, and after locking the secret studio, he put the workpieces in the computer room of the CNC center, and then went out to greet Guo Yi, Wang Ji, and Shu Yao.

Now Guo Yi, Wang Lu, and Wang Ji already hold 10% of the shares of Yunfeng Technology Company, and the shares that Wang Lu originally invested in have become equally divided between the three of them.

Obviously, the three of them didn't want to make money from Yunfeng Technology Company, they thought that this small company couldn't make much money, and out of fun, the three girls who were not short of money at all were divided in this joking way.

Now they have no idea what that 10 percent stake will mean in the near future.

Guo Yi and Wang Ji want to come to see the company, it can be said that they are the company's partners, or shareholders come to see their own things, and Peng Huading has no reason to refuse. However, he did not want them to see his secrets, which were not known to anyone, at least for the time being, and he was afraid that they would not know how much trouble they would cause if they publicized them without knowing how much trouble they would cause.

"Peng Huading, what are you doing? We came to see you from Nanshan City, but you hid yourself, don't you feel embarrassed? Seeing Peng Huading come out, Wang Ji asked angrily.
