The machinery industry is extremely important to the production of the whole society

The machinery industry occupies a leading position in the economy and is the core sector of the industrial system. The development of machinery industry is one of the important links to realize modernization. Without a developed machinery industry, there would be no agriculture, national defense and modern science and technology.

The specialization of machinery industry is an important technical and economic policy, but also an extremely subtle social production organization work, to improve the level of specialization and cooperation is the need for conditions and basis. In addition to reasonable adjustment of industrial layout, the establishment of an effective circulation and transportation network, and the active use of new technology, strengthening organization and management must also be combined with the "three changes".

The "three changes" are standardization, generalization and serialization. Like specialization, its significance is not only applicable to the machinery industry, but also to the entire social production. It main task is to study the best economic benefits with the least labor and material consumption. It plays an important role in saving design costs, accelerating variety development, improving product quality and labor productivity, and facilitating use and maintenance.

1."Three changes" of mechanical products

Specifically to the machinery industry, "three changes" refers to the series of mechanical products, the generalization and standardization of parts. There are many kinds of mechanical products, a wide range of service objects, different requirements, and mutual markets between enterprises. A set or a new piece of equipment from the start from the requirements to the use, the middle must go through the main stages of research, testing, design, manufacturing, installation, use, maintenance, etc.,  A wide range of CNC machine parts, stamping parts, sheet metal parts, die casting parts, a small range to brackets, a screw, all have their production standards.

There are complete sets of single machines, complete sets of units, workshop sets, factory sets, and raw materials such as steel, non-ferrous metals, light industry, chemical industry, and oil the supply of materials and minerals involves a wide range of areas.

Only by establishing a complete industrial standard, can we ensure that the product is in line with the requirements and the quality is in line with each other. If one link is out of whack, it may affect the whole. Implement "three" in the machinery industry it is beneficial to users, manufacturers and countries. This is especially fundamental when production is organized in a specialized and collaborative manner.

2.serialization of some products

Product serialization As we all know, we must use different specifications of machine tools to process parts of different sizes, with different sizes of motors to drive different specifications of machine tools, reasonably determine the specifications of these machine tools, size and other main parameters, and form a series, is this serialization of some products.

The principle of formulating product series must meet the needs of the most changes with the least specifications and models, and pay attention to keeping consistent with similar products of major foreign companies as far as possible, in order to facilitate the import of equipment manufacturing and export supporting needs.

3.The generalization and standardization of parts

The generalization and standardization of parts When enterprises organize production, they generally divide all parts of the machine into several categories such as special parts, universal parts, and standard parts. Special parts are special parts of a machine.

Universal parts refer to certain models and even other models parts available to the machine, for example, the machine vise used to grip the work piece on the milling machine, not only can be used in the universal milling machine, but also in the vertical milling, horizontal milling, shape machine can be used; Similarly, there are various machine tool accessories, hydraulic parts, electrical components, instruments metal table, etc.

Standard parts are parts standardized by the state or the industry, which can be used in a variety of products, such as screws, rolling bearings, etc., and their use is wide and large. For such parts (also including some general parts), due to the large scale of product production, it is conducive to the use of advanced technology and special equipment, and the rational use of raw materials to achieve the economic effect of ensuring product quality and reducing production costs. Xiamen Huaner Technology Co., Ltd. is specialized in CNC machine parts, stamping parts, sheet metal parts and die casting parts, and is very familiar with metal material hardware equipment, and it is also very good for standard control, and it is weak for plastic products.

In the end,in a series of machines, the more common parts and standard parts are used, the higher the efficiency of design and production. For example, the company produces brackets, there are 2 series and 6 types of brackets in the product, the overall size is basically the same, but 99 main parts such as screws, surface treatment, screw hole position can not be used, and need to be manufactured separately.

The standardization of components provides favorable conditions for specialized production and collaboration.
