The first thousand and forty-four chapters do their best
All equipment of Norinco is made in West Germany, and the labor protection worn by workers is also imported from Hong Kong Island. The modern management system is posted in the most conspicuous place. This is completely an advanced Western factory, and there is no trace of a domestic factory.

When they saw the knives produced by the company, the three of them were completely convinced. This kind of knives already has the quality of German knives. It may still have a certain gap between the top knives in terms of material, but it is not too different. Of course,
Some high-precision cutting tools cannot yet be produced, but this does not affect Norinco's status as the most advanced industrial enterprise in the country.
Norinco is far beyond the imagination of the three people. As He Tao said: Norinco is like an oasis in the desert, but this oasis is not responsible for quenching the thirst of tourists, but to turn the entire desert into an oasis.
's burden.
Well, He Tao, the youngest roommate, is now somewhat artistic, and his favorite is Adès. Apart from a box of books, the items he brought back from Germany were half a box of tapes. These were all saved from his usual savings.
He bought it with the money he saved, but he couldn't afford the tape recorder and planned to come back and "ask for money" from Liu Lang.
Although He Tao has some literary and artistic flair, his level is nothing to say. His three years in West Germany were not in vain, and his graduate thesis was also very high-end, on the research on gear processing of compound processing machines.
The compound processing machine is an advanced equipment that has been used internationally.
In the case of spur gear production, the previous gear processing started with the gear body processing on the lathe, then the gear cutting was performed with a hobbing machine, the chamfering was performed with a chamfering machine, and the gear shaving machine was used for finishing.
It is completed after heat treatment.
This kind of product has many advantages, but it is not suitable for the production of products with many varieties and small quantities, especially special gears. In order to solve this problem, production has been transferred to the use of compound processing machines, etc.
The tendency of general machine production line.
When using a multi-tasking machine for gear machining, you can make full use of the strengths of both cw lathes and machining centers.
All processing steps, such as gear cutting and finishing, which were previously performed by equipment, up to heat treatment, can be completed with one processing machine.
Nowadays, when producing many varieties and small quantities, the processing time can be shortened and the number of equipment and machines can be reduced through process integration, and the accuracy of processing can be improved.
He Tao has a good understanding of the mechanical manufacturing procedures through his study of compound processing machine manufacturing. He is very suitable to serve as the technical supervisor of the factory.
Lin Hai studied in the island country, and what he studied was the application of micro-drilling in mechanical processing. This belongs to a special field, and the island country calls it ultra-fine processing.
Ultra-fine machining is to make micro-drills perform highly efficiently during use. A series of factors must be considered: such as various elements of the drill bit itself, processing parameters, hole depth, completeness of installation and the structure of the workpiece, etc.
How to deal with these factors that interact with each other and are very sensitive to the drilling process? This is the core issue in micro drilling processing.
Lin Hai's graduate thesis discussed speed and accuracy, which are also the two most important factors in ultra-fine machining.
Liu Lang doesn't do much research in this area, and there is little domestic involvement in high-precision machining, while island countries have done very in-depth research in this area. Lin Hai's paper is actually of great practical value.
Let’s talk about speed first. For constant linear speed, the smaller the diameter of the tool, the higher the rotation speed required. Here Lin Hai quoted the parameters of an island company. Their 0.3 mm drill bit rotates at 3,000 rpm when processing at a linear speed of five meters.
It is equivalent to eighty turns of a ten millimeter drill bit.
0.3mm can reach 3,000 rpm, a parameter that even Liu Lang was amazed by.
The other is accuracy, which refers to the comprehensive runout after the tool is installed on the machine tool. Of course, the smaller the runout, the better. The same company can control the radial runout at 10,000 rpm when using aerostatic bearings.
Within 0.001, the parameters were quite impressive. Liu Lang deliberately remembered the name of this company: Dazhaohe Company.
Lin Hai studies ultra-fine processing, which is very useful for the next development of Norinco. Such talents must be reused.
Juniper studied in the United States, and what he learned was more "traditional", which is the so-called traditional technology, bending, reverse extrusion, cold extrusion, cold heading, embossing, blanking, bending die, forming die, and deep drawing
, expansion, boring, flanging, etc., these are common molding processes in workshops.
However, these molding processes will never be outdated at any time. The key depends on how much you master them. In addition, these processes are hidden under the mold, and not everyone can know why.
Juniper's paper discusses various forming process techniques, such as forming process stretch bending, three-dimensional stamping and cold extrusion, three-dimensional stamping and embossing, forming process leveling, stopper pins and progressive dies positioned to positive pins, guides
Plate type simple material dropping die, guide pillar type punching die, guide pillar type blanking die, three-dimensional stamping and reverse extrusion, motor stator, rotor core stamping stacking multi-station progressive die, etc.
Of course Liu Lang knew about these craftsmanship. He could tell at a glance that Juniper's level was the highest among the three. As the saying goes, he was the one who was skilled in craftsmanship.
The direction of their research actually has a lot to do with their personalities. Jun Song is a mature and kind-hearted person. When he was in college, he cooked for Liu Lang every day, so the direction of his research naturally leans towards traditional crafts.
Lin Hai studies hard and especially likes to study difficult subjects. Ultra-fine processing is just right for him.
He Tao is very interesting, very smart. If Liu Lang hadn't been there to compare him, he would have been considered a genius. Geniuses like to use tricks and shortcuts. Of course, this doesn't mean that he doesn't work hard, but that he has an active mind, so he
The direction of research is how to produce more conveniently and systematically.
The three of them each have their own strengths, and they are also the talents that Norinco needs now. Needless to say, they immediately got their first jobs in their lives.
The basic salary for the three of them is 2,000 yuan per month. In addition, they enjoy various benefits like the workers. Calculated, it will be more than 3,000 yuan per month. This kind of salary is not as good as that in developed countries, but it is similar.
, in China, they are definitely high-income earners and cannot afford a car, but houses in the capital are no problem...
The three of them are business managers, mainly responsible for product development, and are under the direct supervision of Liu Lang.
Liu Lang is responsible for technology, while Wang Zhendong is responsible for administrative management, system establishment, logistics support, product sales, and financial and tax payments. The two of them are responsible for each.
Of course, as the chairman, Liu Lang is responsible for all aspects of work, but he only provides opinions on matters other than technology and will not personally intervene.
