What are the basic knowledge of CNC machining center

 The CNC machining center is a high-efficiency automated machine tool that is composed of mechanical equipment and a CNC system suitable for processing complex parts.

 The CNC machining center is also one of the most widely used CNC machine tools in the world.

  • ​1. Learn to live up and down.Someone would say, this is not easy? Is it simple, but some people can't do it well. Going to work also requires skills, and this does require accumulation of experience. Commonly processed workpieces will be clamped with flat-nose pliers or three-jaw chucks, some are pressed with a pressure plate, and some workpieces need to be clamped by tooling. Due to different materials, different processing shapes, the size of the clamping force, whether the pressure is balanced, will affect the accuracy of the workpiece processing, and the deformation of the workpiece after processing. Often when a colleague uses flat-nose pliers to clamp a workpiece to make a fine hole, the gauge can go down before the pliers is loosened, and the gauge can't go down when the pliers is loosened. This is because the clamping force has not been mastered. The clamping force is large, the workpiece is deformed, the clamping force is small, and the workpiece ran away during the milling process, which is not good.
  • 2. Learn to align, score, and set the knife.This is very basic, the basic skills of a machining center.
  • 3. Learn to sharpen drills.Dry machining center, if you often need to punch holes, the drill bit must be able to grind. If not, you should still spend more time practicing on the grinding wheel.Drill bit formula: the cutting edge is flat against the wheel surface, the drill shaft is inclined to release the front angle; the sharpening from the edge to the back, swinging up and down, the tail does not warp.
  • 4. Learn to read drawings.The drawings must be read, the drawings are the language of robots. Without understanding the drawings, there is no way to analyze the process, let alone programming. You must be careful when looking at the drawing. First of all, you must see whether it is the first or third corner drawing, and then see where the benchmark is, and there are some important dimensions, especially the geometric tolerances in the drawings.
  • 5. Understand the knowledge of commonly used tools.It is necessary to understand the commonly used tools and their uses. Know what tool is used for.
  • 6. Understand common material properties.does not need to be too deep, but you must understand the characteristics of common materials. For example, if you don't understand the hardness of this material, the speed feed given by your program may be unreasonable.
  • 7. Learn to program with computer software.Programming is divided into manual programming and automatic programming. Due to the complexity of the workpiece in the machining center, it is still necessary to learn to program with computer software. You can learn mainstream software such as UG, PowerMILL, etc.
  • 8. Learn to use measuring tools.For commonly used measuring tools, you must use them skillfully. Such as vernier caliper, micrometer, inner diameter gauge, depth gauge, etc.
