CNC machining center is a high efficiency automatic machine tool, which is composed of mechanical equipment and CNC system, and is suitable for machining complex parts. CNC machining center is also one of the most widely used CNC machine tools with the highest output in the world. Its comprehensive processing ability is strong, the workpiece can be clamped at a time to complete more processing contents, and the processing accuracy is high. It is equipped with a tool magazine, which is suitable for single piece processing with complex shape and high precision requirements, or small and medium batch production of many varieties.

What basic knowledge should a NC friend who has just contacted NC machining center or is committed to the development of this industry master? Today, I will give you a list of my experience. Only by constantly improving their own technology, will better development in this industry, wages will also have a corresponding increase. (of course, the skill is good, and the salary is not necessarily high, which is sometimes helpless.)
1. Learn to live up and down.
Someone would say, isn't that easy? It's easy, but some people can't do it well. It also needs skills to live. It really needs experience. Generally processed workpieces will be clamped with flat pliers or three jaw chuck, some with pressing plate, some workpieces still need to be clamped with tooling. Because of different materials and different machining shapes, the accuracy of workpiece machining and the deformation of workpiece will be affected by the size of clamping force and the balance of pressing force. There are often colleagues who use flat tongs to clamp workpieces for fine holes. Before loosening the tongs, the Tong gauge can go down. When loosening the tongs, the Tong gauge can not go down. This is that the clamping strength is not well controlled. The clamping force is large, the workpiece is deformed, the clamping force is small, and the workpiece runs in the milling process, which is not good.
2. Learn to align, divide and align.
This is very basic. It is the basic skill of the machining center.
3. Learn to grind the bit.
Dry machining center, often need to drill, the drill must be able to grind. If not, you should spend more time on the grinding wheel.
The pithy formula of grinding bit: the cutting edge shall be leveled and the wheel surface shall be lean, and the cutting axis shall be inclined to set out the front angle; the back shall be grinded from the cutting edge to the back, and the tail shall not be tilted up or down.
4. Learn to read drawings.
Drawings must be able to read. Drawings are the language of robots. Do not understand the drawings, there is no way to analyze the process, let alone programming processing. When you look at a drawing, you must be careful. First, you need to see whether it is the first angle drawing or the third triangle drawing, and then you need to see where the datum is. There are also some important dimensions, especially the geometrical tolerance in the drawing, which should be paid more attention to.
5. Understand common tool knowledge.
For commonly used tools and their use, it is necessary to understand. Know what knives are used for.
6. Understand common material properties.
It doesn't need to be too deep, but it's important to understand the properties of common materials. For example, if you don't understand the hardness of this material, the program you compiled and the speed feed given may not be reasonable.
