Chapter 144: To each his best
All the equipment of NORINCO Group is made in West Germany, and the labor protection worn by the workers is also imported from Hong Kong Island, and the modern management system is pasted in the most conspicuous place.
When seeing the knives produced by the company, the three people are completely convinced, this kind of knives already have the quality of German knives, perhaps there is a certain gap between the top knives in terms of materials, but it is not too much, of course, some high-precision knives can not be produced, but this does not affect the status of North Industries Group is the most advanced industrial enterprise in China.
NORINCO Group is far beyond the imagination of the three people, as far as He Tao said: NORINCO Group is like an oasis in the desert, but this oasis is not the responsibility of tourists to quench their thirst, but the burden of turning the entire desert into an oasis.
Well, He Tao, the youngest roommate, now has some literature and art, his favorite is Adesi, the items he brought back from Germany are half a box of tapes in addition to a box of books, which are bought with the money he usually saves money, but he can't afford to buy a tape recorder, and he is going to come back to ask Liu Lang for money.
Although He Tao has some literary and artistic atmosphere, his level is not in vain, three years in West Germany was not in vain, and the graduate thesis is also very high-end, on the research of gear processing of composite processing machines.
The multitasking machine is an advanced equipment that has begun to be used internationally.
In the case of spur gear production, the previous gear processing started from the gear body processing on the lathe, and then the gear cutting process was carried out with a hobbing machine, the chamfering machine was chamfered, and then the finishing was carried out by the shaving machine, and then it was completed by heat treatment.
This product has many advantages, but it is not suitable for the production of high-mix, low-volume products, especially special gears, and in order to solve this problem, there is a tendency to shift production to the production line of general-purpose machines such as multitasking machines.
When using multitasking machines for gear machining, it is possible to make full use of the advantages of both C-lathes and machining centers.
All machining processes, such as tooth cutting and finishing, which were previously performed by equipment, up to heat treatment, can be performed on a single processing machine.
Nowadays, when producing a large number of products and a small number of products, it is possible to shorten the processing time and the number of equipment and equipment by intensive processes, and improve the accuracy of machining.
He Tao has a great understanding of the mechanical manufacturing process through the study of compound processing machine manufacturing, and he is very suitable for the work of technical supervisor in the factory.
Lin Hai studied in the island country, and learned the application of micro drilling in machining, which belongs to a special field, and the island country calls it ultra-fine machining.
Ultra-fine machining is to make the micro drill play a high efficiency in use, which should consider a series of factors: such as the various elements of the drill bit itself, processing parameters, hole depth, the perfection of installation and the structure of the workpiece.
How to deal with these factors that affect each other and are very sensitive to the drilling process? This is the core problem in micro drilling processing.
Lin Hai's graduate thesis was about speed and precision, which are also the two most important factors in ultra-fine machining.
Liu Lang does not have much research on this aspect, and there is little high-precision processing in China, while the research in this area is very deep in island countries, and Lin Hai's paper is actually very practical.
First of all, the speed, the constant linear speed, the smaller the diameter of the tool, the higher the required speed, here Lin Hai quoted the parameters of a company in the island country, their 0.3 mm drill bit in the processing at a linear speed of 5 meters when the speed of 3,000 revolutions, that is, equivalent to 80 revolutions of a 10 mm drill bit.
0.3 millimeters can reach 3,000 revolutions, a parameter that even Liu Lang is amazed.
The other is the accuracy, refers to a comprehensive runout after the tool is installed on the machine tool, of course, the smaller the runout, the better, the same company, in the case of using aerostatic bearings, at 10,000 rpm, the radial runout control is within 0.001, the parameters are quite cattle, Liu Lang specially remembered the name of this company: Dazhao and the company.
Lin Hai's research is ultra-fine processing, which is too useful for the next development of NORINCO Group, and this kind of talent must be reused.
Juniper studied in the United States, and he learned more "traditional", which is the so-called traditional technology, stretch bending, reverse extrusion, cold extrusion, cold heading, embossing, blanking, bending die, forming die, drawing, expansion, turning, flanging, etc., which are common molding processes in the workshop on weekdays.
But these molding processes are not outdated at any time, the key depends on how much you master, and these processes are hidden under the mold, not everyone can know why.
Juniper's paper discusses the skills of a variety of molding processes, such as forming process - drawing and bending, three-dimensional stamping - cold extrusion, three-dimensional stamping - embossing, forming process - leveling, stepper pin and progressive die to the positive pin positioning, guide plate type simple material drop die, guide pillar type punching die, guide pillar type blanking die, three-dimensional stamping - reverse extrusion, motor stator, rotor core stamping stacking multi-station progressive die and so on.
Of course, Liu Lang knew these crafts, and he could see at a glance that Juniper's level was the highest among the three, and the so-called great ingenuity was referring to him.
The direction of their research actually has a lot to do with their personality, Juniper is an old man who is kind-hearted, and when he was in college, he cooked for Liu Lang every day, and his research direction naturally tended to traditional crafts.
Lin Hai studied hard, especially like to study difficult knowledge, and ultra-fine machining is just right for him.
He Tao is very interesting, very smart, if there is no Liu Lang on the side to compare, he is also a genius, genius people like to take shortcuts, of course, this is not to say that he is not hardworking, but active thinking, so the direction of his research is how to produce more conveniently and systematically.
The three of them have their own strengths, and they are also the talents that NORINCO needs today, needless to say, they immediately got the first job in their lives.
The basic salary of the three is 2,000 yuan per month, and they enjoy the same welfare benefits as the workers, which will exceed 3,000 yuan per month, which is not as good as that of developed countries abroad, but it is not about the same, in China, it is an absolute high-wage class, and the car cannot be bought, but the house in the capital is no problem.............
The positions of the three are all business executives, mainly responsible for product development, and are under the direct supervision of Liu Lang.
Liu Lang is responsible for technology, and Wang Zhendong is responsible for administrative management, system establishment, logistics support, product sales, and financial taxes.
Of course, Liu Lang, as the chairman of the board, is responsible for the overall work, but when it comes to matters other than technology, he only puts forward opinions and will not interfere personally.
