The machine-building enterprise is implementing a project for the technical re-equipment of production. Development of an investment project for the technical re-equipment of OAO Ok-Loza. Effects of the replacement of technological equipment

The technical re-equipment of the enterprise is one of the urgent tasks that companies in the machine-building sector face today. And here the main thing is to find a professional, experienced contractor who is able to give not only a comprehensive assessment of the state of production, but also offer modern solutions that increase its efficiency. One of the latest such projects was implemented by Pumori-engineering invest, which specializes in complex technical re-equipment. The customer is a machine-building enterprise, where it is necessary to modernize one of the machine shops to ensure efficient production given range of products.

BASED ON TECHNICAL AUDIT

The work began with a technological audit of the existing production. Specialists of the technical service of Pumori-engineering invest conducted a survey, paying attention to the technologies and equipment used at the enterprise, the production planning and management system, product quality control, etc.

At the same time, the design and technological documentation for manufactured parts and assembly units (DSE) was studied. The customer presented drawings of about one and a half thousand DSE of various types and categories of complexity. For their manufacture, the company uses modern and outdated equipment of the following types: turning, milling, turning-milling, cylindrical grinding, surface grinding and electroerosive. Based on the results of the technical audit, a concept for the modernization of production was formed, primarily in the technological sphere.

NON-STANDARD APPROACH

The second stage of technical re-equipment is the development of promising technologies for processing parts, the selection of a modern high-performance one, the calculation of its quantity, the development of a technological layout of the workshop and the calculation economic indicators project.

When working with a large number of DSUs, the standard approach is the one in which individual DSUs are combined into groups according to their design and technological features. Each group has a representative part. For its manufacture, a transient technological process is being developed with necessary equipment and labor input is normalized. For the remaining parts of the group, the so-called reduction coefficients are assigned - their use allows us to give a fairly accurate assessment of the labor intensity of manufacturing each part.

However, the complexity of this project was that due to the variety in the design of parts, materials used, accuracy and other parameters, using the standard approach, it would be necessary to form a huge number of groups with a relatively small number of parts in each. As a result, the time spent on the development of the entire range of DSE would be significant, while the duration of the project is limited by the customer. Therefore, Pumori-engineering invest specialists have developed an improved methodology. It allowed to combine parts into groups only by types of processing, and assign reduction factors based on the following parameters:

• amount of machining;
• workpiece type;
• accuracy and roughness;
• the presence of heat treatment, etc.;

This approach significantly reduced the number of teams, speeding up the project without sacrificing quality.

WORK FOR RESULT

Based on the developed technological processes and the calculated labor intensity, a list was formed, the required number was determined, taking into account the restrictions set by the customer: annual fund of working hours, maximum load factor, interchangeability of machines. Technical requirements have been developed for the equipment, according to which it is recommended specific models machine tools. Technological layout shop is designed taking into account the results of the analysis and optimization of material flows.

Today, the customer of the project for the technological modernization of production, together with Pumori-engineering invest, is implementing the proposed solutions. The project is expected to be fully completed by the end of 2018. Without waiting for the final stage, we can confidently state that the solutions proposed by the contracting company are already increasing production efficiency.
