    The method of improving the precision of machining precision by CNC lathe

    The method of improving the precision of machining precision by CNC latheIn the machining cnter, the machining of CNC lathes generally requires the use of multiple tools, so we must organize the processing order reasonably, which is conducive to improve machining accuracy, processing efficiency and economic benefits.1. When organizing the processing sequence of CNC lathes, the same general guidelines for "basis first", "first face back hole", "first master second" and "first coarse and fine" should be followed.2. The selection of the positioning reference directly affects the organization of the processing order. The surface as the positioning reference should be processed first to provide a firm positioning reference for processing other surfaces. Because the surface of the process is selected after the positioning reference is selected, it may be the positioning standard of the next process. Therefore, after the positioning reference of each processing step is determined, the......

    How much do you know about the importance of shovel scraping on machine tools?

    What is scraping? The so-called shovel scraping is a work in which the technician uses a blade or a scraper to shovel the machine guide rail. It is the friction surface (the table top, the saddle, the headstock, etc.) that needs to be scraped and ground. The skilled person's shovel-scraping process can obtain flatness, straight angle, and straightness that are difficult to achieve by machining. The shovel is not a casual and casual operation. It is actually a method of reproduction. It is almost perfect to copy the mother. This mother is a standard plane and is also hand-built. Many people will wonder if people will be more powerful than machines. Can manual shovel can improve these machined surfaces? If it is purely its appearance, it must be impossible, and the work will not be more beautiful. Why do you have to shovel flowers? Because the purpose of the machine tool is to make other m......

  • Reasons and solutions for the unstable size of common CNC lathes

    Reasons and solutions for the unstable size of common CNC lathes

    Reasons and solutions for the unstable size of common CNC lathesDimensional accuracy refers to the degree of conformity between the workpiece size and the dimensional requirements of the machine. Therefore, in the numerical control lathe internship, in order to improve the dimensional accuracy of the part, it is necessary to pay attention to the operation skills in the machine operation. Common control methods for dimensional accuracy of parts, such as accurate tool setting, tool wear compensation adjustment, and modification of dimensional control accuracy in the program. The resulting workpiece is accurate in size but the surface is not clean.1. The tool is not sharp and the tool tip is damaged.If the tool is not sharp after being worn or damaged, re-grind the knife or choose a better tool to re- sharpen the knife.2, the machine tool generates resonance, the placement is not stableTo select a place where the ground is stable, place the CNC machine and adjust the angle. Fixed ......
