1 thought on “How to choose Dongguan CNC milling machine processing manufacturers?”

  1. Milling machine () mainly refers to the machine tools that use the various surfaces of the workpiece with milling cutters. Generally, the milling cutter is mainly moved by rotation movement, and the movement of workpieces and milling cutters is the feed movement. It can process planes, grooves, and can also process various curved surfaces, gears, etc. Milling machine is a machine tool for milling and drilling with milling cutters. In addition to being able to milling planes, grooves, wheel teeth, threads, and flower keys, it can also process more complicated fabrics. The efficiency is higher than the plane. It is widely used in the mechanical manufacturing and repair departments.
    Muling machine is a widely used machine tool that can process planes (horizontal planes, vertical planes), grooves (key grooves, T -shaped grooves, dycles, etc.) on the milling machine, Spiral), spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can be used to process the surface of the rotary, the inner hole processing, and the cutting off. When the milling machine is working, the workpiece is installed on the workbench or on the attachment of the separation head. The milling cutter rotates the main movement. It is supplemented by the inlet motion of the workbench or milling head to obtain the required processing surface. Because it is a multi -blade cut cutting, the production rate of milling machines is high. Simply put, milling machines can millronile, drilled and pilot machining machine tools.
    Neramial milling machines can be processed for complex appearance and characteristics. Milling machining centers can be performed by tri -axis or multi -axis milling. It is used for processing, molds, inspection, tires, thin -walled complicated curved surfaces, artificial prosthesis, leaves, etc. When selecting CNC milling and processing content, the advantages and key role of CNC milling machines should be given full. CNC milling machines are a CNC machine tool with a strong processing function. The rapidly developing processing centers and flexible processing units are produced on the basis of CNC milling machines and CNC tools. Both are inseparable from milling methods. Because the CNC milling process is the most complicated and the technical problems that need to be solved are the most. Therefore, when people study and develop CNC systems and automatic programming languages, they have also focused on milling and processing.
    This Milling machine processing:
    The processing surface shape of the milling machine is generally composed of straight, arcs or other curves. Ordinary milling machine operators are based on the requirements of the pattern. Continuously change the relative position between the tools and the workpiece, and then cooperate with the selected milling cutter speed to make the tool cutting the workpiece to process the workpiece of various shapes.
    This machine tool processing is to divide the tool and workpiece motion coordinates into minimum units, that is, minimum displacement. According to the requirements of the workpiece program, the CNC system moves each coordinate to the minimum displacement, so as to achieve the relative movement of the tool and workpiece to complete the processing of the parts.
    The functional characteristics of CNC milling machine:
    It CNC milling processing, in addition to the characteristics of ordinary milling machine processing, also has the following characteristics:
    1, strong adaptability and flexibility of parts processing, good flexibility, can process outline shape shape Special complicated or difficult to control the size parts, such as mold parts, shell parts, etc.;
    2, parts that can process ordinary machine tools that cannot be processed or difficult to process, such as complex curve parts described in mathematical models and three -dimensional space described by mathematical models and three -dimensional space described Curved parts;
    3. After the processing can be processed at a time, parts of multiple processes must be performed;
    4, high processing accuracy, stable processing quality, and the pulse equivalent of CNC devices is generally 0.001mm. High -precision CNC systems can reach 0.1 μm. In addition, CNC processing also avoids the operating errors of operators;
    5. High degree of production automation can reduce the working intensity of the operator. It is conducive to the automation of production management;
    6. High production efficiency, CNC milling machines generally do not need to use dedicated crafts such as dedicated fixtures. When replacing workpieces, you only need to call the processing procedures, fixture tools and adjustment of tools stored in CNC devices. Data is sufficient, so the production cycle is greatly shortened. Secondly, CNC milling machines have the functions of milling machines, beds, and drilling machines, which highly concentrate the process and greatly improve production efficiency. In addition, the main axis speed and feed speed of the CNC milling machine are stepless transmission, so it is conducive to the optimal cutting amount;
    The characteristics of CNC milling machines:
    1. Processing characteristics
    It is a frame-shaped plane or unqualified levels of all levels. If the processing site is the curved contour, it should be determined according to the geometric shape of the curved surface. According to the requirements of the parts processing requirements, on the basis of general CNC milling machines, increase the CNC header or CNC rotation workbench. At this time, the system of the machine tool is a four -coordinate CNC system, which can process spiral grooves and blade parts.
    2, size
    The lifting desktop -type CNC milling machine with smaller specifications. Its workbench width is mostly below 400mm. It is most suitable for the processing of small and medium -sized parts and complex surface contour milling tasks. Large specifications such as Dragon Gate milling machines, the workbench is more than 500-600mm, which is used to solve the processing needs of large -sized complicated parts.
    3, accuracy
    The accuracy standards for CNC milling machines in my country, of which the CNC stand -type milling machine lift packets have professional standards. The standard stipulates that the positioning accuracy of its linear motion coordinates is 0.04/300mm, the repeated positioning accuracy is 0.025mm, and the milling essence is 0.035mm. In fact, the precision of the machine tools has considerable reserves, which is about 20%compressed by about 20%compared with the national standard. Therefore, from the perspective of accuracy, general CNC milling machines can meet the processing needs of most parts. For parts with higher accuracy requirements, a precision CNC milling machine should be considered.
    4, batch
    For large quantities, users can use special milling machines. If it is a small and medium -sized and frequent periodic repetitive production, it is very suitable to use CNC milling machines, because the first batch of preparation of many fixtures and procedures can be stored and reused. In the long run, it is inevitable that a high degree of automation milling machine instead of ordinary milling machines to reduce the increasing productivity of workers. rn数控铣床的主要功能:rn(1)点位控制功能:数控铣床的点位控制主要用于工件的孔加工,如中心钻定位、钻孔、扩孔、锪孔、 Various holes and other holes and holes are processed.
    (2) Continuous control function: Through the straight -line interpolation, arc interpolation or complex curve interpolation motion of CNC milling machines, the plane and curved surface of the milling processing workpiece.
    (3) The radius compensation function of the tool: If it is programmed directly according to the contour line of the workpiece, the actual contour line will be larger when processing the contour of the workpiece. A knife -diameter value. Using the method of compensation for the radius of the tool, the CNC system automatically calculates the center trajectory of the knife appliance, so that the center of the knife is deviated from the contour of the workpiece, a tool radius value, thereby processing the outline that meets the requirements of the drawing. Use the function of the radius of the tool to change the amount of compensation for the radius of the tool, and it can also compensate for the amount of wear and processing errors to achieve rough processing and fine processing of the workpiece.
    (4) The length of compensation function of the tool: Change the amount of compensation for the length of the tool, which can compensate the length deviation of the tool after the knife is changed. It can also change the plane position of the cutting processing, control the axial positioning accuracy of the tool.
    (5) Fixed recycling processing function: Applying a fixed circulation processing instruction, which can simplify the processing program and reduce the workload of programming.
    (6) Sub -program function: If the shape of the processing workpiece is the same or similar, write it into a subroutine and call it by the main program, so that the program structure is simplified. Quote the function of the subroutine to modular the processing program. It is divided into several modules according to the process of the processing process, and the subroutines are compiled separately, which is called by the main program to complete the processing of the workpiece. This modular program is easy to process and debug, and optimizes processing technology.
    The processing range of CNC milling machine:
    (1) Plane processing: CNC machine tool milling plane can be divided into the level (XY) processing of the workpiece, the positive plane (XZ) processing of the workpiece, and the side level of the workpiece (YZ) processing. As long as the two -axis semi -controlled CNC mill machine can complete such a flat milling processing.
    (2) Curfach processing: If you milling complex curved surface, you need to use three -axis or even more axis linkage CNC milling machines.
