How Do I Choose the Best Used Machine Tools?
The selection of CNC machine tools is for a manufacturing enterprise. To improve production capacity, it often starts from the aspects of production management, manufacturing process, and production equipment for technical transformation.
Selection of CNC machine tools
Right!
- The selection of CNC machine tools is for a manufacturing enterprise. To improve production capacity, it often starts from the aspects of production management, manufacturing process, and production equipment for technical transformation.
- For a manufacturing enterprise, improving production capacity often starts from the aspects of production management, manufacturing process, and production equipment for technological transformation, and these parts are mutually influential and restrictive. In the technical reform, the selection of production equipment, CNC machine tool updates, maintenance, procurement, etc. must take into account what kind of environment to use, how to manage, how to achieve the best economic results, and so on.
The selection of manufacturing equipment is to serve some products. The selected equipment may be used for part of the process of product parts, or it may be used for all processes. The level of manufacturing depends first and foremost on the design of the technological process. It will determine what methods and means are used to process, and thus also determines the basic requirements for the use of equipment. This is also the basis for technical organization and management of production. After the basic requirements for equipment selection are determined, it is also necessary to choose according to what technical level equipment can be provided on the market. For most small and medium batch manufacturing enterprises, it is a development trend to choose CNC machine tools to replace old machine tools or enhance production capacity.
Comparing the performance of ordinary and CNC machine tools, CNC machine tools have the ability to process complex shaped parts, are suitable for a variety of processing objects (flexible), have high processing quality, precision, and processing efficiency, and are suitable for CAD / CAM networking and manufacturing processing information Integrated management; high utilization rate of equipment and low uptime costs.
Choosing CNC machine tools is a comprehensive technical issue. Nowadays, whether at home or abroad, a variety of equipment can be produced and provided. After decades of development, CNC machine tools have evolved into a large family group that can complete a variety of processing and manufacturing requirements. How to choose suitable equipment from a wide variety of expensive equipment, how to make these equipment play a full role in manufacturing and meet the future development of the enterprise, how to correctly and reasonably purchase accessories, tools, and software supporting the host Technology, after-sale technical services, etc., enable the purchased equipment to achieve a better investment ratio ... These issues are all issues that buyers must consider and deal with one by one.
1. Determine the "family" of typical machining workpieces
Determining what parts to process is the first step in selecting equipment. According to the needs of technological transformation and production development, the enterprise determines which parts and processes are to be completed with new processing equipment. It is necessary to consider the long-term planning of product development. Group these parts into groups using grouping techniques to determine the typical family of parts to prepare for the main machining target. In the classification, it is often encountered that the specifications of the parts are greatly different, the shapes of the parts are greatly different, and the processing hours of various types of parts greatly exceed the full-load hours of the equipment. Therefore, it is necessary to further select a typical workpiece family that determines the production program and is closer to the requirements. . Typical workpiece families can be divided into diamonds (boxes), plates, swivels (disks, sleeves, shafts, flanges) and special shapes according to their appearances; according to the requirements of processing accuracy, they can be divided into ordinary and precision grades. Wait. The classification of typical parts is clear, and the basic processing equipment is clear.
Second, the process specification design of the typical part family After determining the processed parts, it is necessary to use the scientific viewpoint of NC machining technology to carry out a new planning and design of the process flow. This includes the change of the original process production process and the feasibility of exploring new process methods. To explore the feasibility of modern production management and logistics management, to explore the feasibility of using advanced tooling to greatly increase production efficiency, to explore the reasonable preparation process of numerical control equipment and other equipment (general, special-purpose) on the production line, etc., the purpose is to Hope to get the best process manufacturing process after using CNC machine tools. The following are reasonable processing techniques for several typical types of parts.
