Many people have heard of CNC machining, but they don't know much about it. What is CNC machining? What is the structure of the machining center? Today I will give you a popular science.
CNC machining, also known as numerical control machining, refers to processing using numerical control tools. Since the CNC processing program is compiled, it is controlled by the computer. Therefore, CNC machining has the advantages of stable processing quality, high precision, good repeatability, ability to process complex-shaped surfaces, and high processing efficiency. The CNC machining center adopts a single-column fixed and table-top movable structure. It is mainly composed of a bed, a column, a slide table, a table, a spindle, a screw, a guide rail, a lubrication system, a cooling system, a CNC console and an electrical control system.
Generally speaking, the factors that affect the efficiency of CNC machining include equipment failure, production management, process technology, CNC tools, personnel skills, and product structure. Then, what is the reason why product structure specifically affects the efficiency of CNC machining?
1. The specifications, sizes and structures of various parts are very different, and the versatility of process equipment such as machine tools is not high;
2. Many enterprises are often faced with production tasks of multiple varieties, small batches, and short production cycles, so the process system is required to have a high response speed;
3. The structure of the product parts is complex and difficult to process;
4. Thin wall, prone to processing deformation. There are many thin-walled and deep-cavity structures, which are typical weakly rigid structures;
5. The selection of cutting tools and cutting parameters is a difficult point. Because the development of the cutting tool industry cannot keep up with the pace of development and application of new materials, it also lacks the support of cutting processing database.
How to improve the processing efficiency of CNC machining? Generally speaking, the method to improve the efficiency of CNC machining is:
1. Change the perception of CNC technology
CNC technology is a comprehensive technology. In addition to CNC machine tools, there must be corresponding supporting technology and talent support, especially people play a decisive role in the CNC processing process, management personnel, engineering and technical personnel, engineering maintenance personnel and operators The technical capability directly affects the production efficiency of CNC machine tools.
2. Develop an effective tool management system
For example, adjust the tool in advance to reduce the installation and adjustment time of the tool on the machine tool, and manage the tool through the management system to reduce errors caused by manual management.
3. Management of fixtures.
Because the selection of fixtures is directly related to the installation time and measurement time of the workpiece, the management of fixtures should be realized.
