INTRODUCTION
The volume of production in the automotive industry of the President of the Republic of Uzbekistan Shavkat Mirziyoyev has decreased 2.8 times over the past three years. This has a significant impact not only on the growth rate of industrial production, but also on the growth of GDP. The volume of imports in this area is several times higher than exports, and the level of localization remains below 20% of imports.
Only 13% of the 21,000 standards of the International Organization for Standardization have been introduced in our country.
We have huge reserves. However, a total of $ 1.54 billion in forecasts was not met last year. Of this, $ 570 million will go to the enterprises of the Cabinet of Ministers. The $ 970 million target was not met by regional businesses. The number of countries to which our products are exported decreased from 176 in 2010 to 138.
Let's talk about the tasks ahead in 2017. We need to export $ 10.8 billion worth of goods.
In 2016, it is necessary to implement contracts for the export of products worth a total of $ 7.7 billion at international industrial fairs in Tashkent and abroad.
Implement 12 social and infrastructure programs for 2017-2021. Of these, 8 programs were approved. In the near future, it is necessary to develop and submit a package of documents on the improvement of transport and trade services, the reconstruction of roads and drinking water supply systems.
Based on the annual program given inhe weight of the part, we chose the type of medium series production.
The conditions in this type of production enterprises require flexibility, taking into account the requirements of compactness and market economy.
The equipment and devices selected in the technological process are aimed at increasing labor productivity and reducing costs.
The technological process, which consists of modern metalworking methods, casting, vibrating cleaning machines, pressure treatment methods, allows to achieve the required level of production in a timely manner and in a timely manner.
The following requirements must be met in the project.
1. Use of the technological process used to reduce grain time.
2. Use of cheap and compact metal cutting machines and cutting tools.
3. Wide use of standardized and standardized equipment.
4. Use of modern project organization methods.
5. Achieve more surface treatment in one installation.
These requirements reduce the cost of technological equipment and reduce the cost of production.
The equipment and fixtures we design are standardized and the equipment is highly efficient and therefore meets the above requirements.
So, with our project, we can contribute to the development of our .
