Focus - Servo motor manufacturers, precision machining plants, Dongguan die castings, as the lifeline of precision machining plants, in the past, there were basically no reworked parts for CNC machine tools. Therefore, if the main precision machining basically only has the possibility of discarding, how to ensure the machining accuracy in the machining process? The machine manufacturer explains the focus of the relevant knowledge. Precision CNC machine tools generally use more than two tools, and by rationally arranging the processing sequence, it helps to improve the processing accuracy. When arranging the processing process, the processing principles that must be followed are those stipulated by the benchmark linearity, primary and secondary, secondary and surface inspection departments. The position of the datum plane directly affects the processing environment of the subsequent process, so the datum surface must be processed first in order to provide an accurate position reference for the subsequent process. Processing data can serve as the next processing reference. If the positioning datum of each process is roughly arranged, from one process to the host front end to the entire precise process sequence.
Before arranging the work program, it is also necessary to know whether the preprocessing of the precision machine tool needs to wake up, such as: high blank precision, more accurate and reliable positioning, or processing balance, no preprocessing is required, the processing process should be directly arranged, so the blank reference should be determined Accuracy, if pre-processed, is generally done by the machine tool.
When machining parts in a machine shop, it is difficult to guarantee a machine between standard and non-machined surfaces. If the drawing machined surface is wrong, it must be left on the unmachined surface of the blank material balance treatment to ensure the compound and machined drawing requirements between the standard surface and the non-machined surface.
The Importance of Machining Work Protection?
CNC lathe has good processing flexibility. High adjustment and high machining accuracy have long been concerned by automobile manufacturers, meeting the needs of each CNC lathe processing user, and becoming the goal pursued by automobile manufacturers. During the machining process, each component is strictly Execute process discipline, see drawings, see control points, roughness and technical requirements of related parts, determine the machining process of production parts. Here's the importance of machine work protection
In the production process of large-scale machining, the process directly related to the conversion of raw materials into products is called process. Including blank manufacturing, parts processing, heat treatment, quality inspection, mechanical assembly. The adjustment and maintenance of machine tools is an auxiliary process to ensure the normal process of tool and fixture manufacturing. The host should wear protective equipment before working. Gloves and scarves are prohibited.
Before starting the machine tool, you must understand the purpose and operation method of each handle, and check whether the operation of each part of the machine tool is normal. Before starting the machine, the tool and workpiece must be clamped with a wrench. Large machining machines should not be started without the permission of a person in the know. Do not change speeds, clear debris, or measure dimensions before the machine is started. Do not touch the operating parts. If there is foreign matter or debris on the machine, do not blow with your hands or mouth. When the host is working, if it is found that the object is loose or the equipment is abnormal, it should stop immediately. After the operation, the machine tool and the machine tool workplace should be cleaned up, and tools, workpieces and other items should not be placed on the machine tool table.
During large-scale machining, do not touch moving parts such as tools and workpieces, and do not lean on the machine tool to avoid other accidents. When two people operate the machine at the same time, they should have a clear division of labor and cooperate closely.
