Use and Quality Judgment of Vertical CNC Machining Center of CNC Milling Machine

CNC milling machine is an automatic processing equipment developed on the basis of ordinary milling machine. The processing technology of the two is basically the same and the structure is similar. CNC milling machines are divided into two categories: no tool magazine and tool magazine. CNC milling machines with tool magazines are also called machining centers.

　　 CNC milling machine vertical CNC machining center in addition to the characteristics of ordinary milling machine, CNC milling also has the following characteristics:

　　 1. Flexible handling of parts, can handle parts with particularly complex contours or difficult to control dimensions, such as modular parts, shell parts;

　　 2. It can handle parts that can not be processed or difficult to be processed with ordinary machine tools, such as complex curved parts described by mathematical models and three-dimensional space surface parts;

　　3. Parts can be processed after fastening and positioning for multiple positioning operations;

　　 4. High-precision processing, stable and reliable processing quality, the pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1μm. In addition, the control of processing numbers can also avoid operator error;

　　 5. High degree of production automation, which can reduce the operator's work intensity. Suitable for automation of production management;

　　 6. High-efficiency CNC milling machines generally do not require the use of special accessories and other special process equipment. When replacing parts, it is only necessary to call the machining program stored in the numerical control device, clamp the tool, and adjust the tool data, which greatly shortens the production time. Cycle two, the CNC milling machine has the functions of drill bit, trampoline and drilling. The vertical CNC machining center of the CNC milling machine in the manufacturing process has a high concentration, which greatly improves the production efficiency. In addition, the speed of the spindle and the advancing speed of the CNC milling machine are infinitely variable, so it is beneficial to choose the optimal cutting amount.

　　 I think a good machining center still has a price. This is not to say that the price is low, but to bring the value of the equipment to the customer at a certain price. We do not require the production of 45 million nationwide. The equipment can achieve the processing effect of millions of imported equipment, but at least the price is worth it. More general question, so the answer is not detailed, we will respond about 600,000 according to the home team. First of all, let me talk about the accuracy of the first two. I think accuracy is not a problem for current machining centers. Whether it is a national private service system or a private import system imported from abroad, micron accuracy is not a problem. General processing manufacturers can reach "silk" or 0.01 mm, which is good. Choose more expensive equipment. Therefore, accuracy is not the most important condition for judging the quality of equipment.

　　Second, I think it should be "stiff". Compared to choosing "flexibility" as a machining center, you have to deal with flexibility, which means it can handle other models at any time, and I must say "rigid" means that it is consistent in quality when dealing with the same model Every product. For example, I want to make a hole with a diameter of 54 and a tolerance of ±0.05. The machining center is the first one, no problem, do it a second time. , Out of the brand, the third can be qualified again, the fourth and prejudice.
