What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

The relationship between the main parameters of bearing temperature rise and oil-air lubrication

In high-speed machining, the thermal characteristics of the electric spindle is a main factor that affects the machining accuracy, and directly affects the increase in the speed of the electric spindle.In the temperature rise of the electric spindle unit, the bearing temperature rise is an extremely important part.The temperature rise and temperature distribution of the bearing have a great influence on the performance of the bearing. It will affect the assembly of the bearing, the working clearance of the bearing, and the performance of the lubricant.An increase in temperature will worsen the lubrication state of the bearing, leading to premature bearing failure.Therefore, the thermal analysis of the bearing system can help us choose and use the bearing reasonably, and can provide a basis for the failure and failure analysis of the bearing system.
At present, the electric shaft usually adopts precision angular contact bearings that are suitable for high speed and can bear radial and axial loads at the same time.The test shows that the three main parameters of the oil-air lubrication system (kinematic viscosity of lubricating oil, compressed air pressure, compressed air flow) affect the temperature rise of precision angular contact bearings, and the following conclusions are drawn:
The viscosity of lubricating oil affects the temperature rise of the bearing through the internal friction and heating of the bearing. With the increase of the viscosity, the temperature rise of the bearing will increase, and this trend is more obvious in the high-speed section, but as the viscosity further increases, the bearing temperature rises. The ascending gradient shows a decreasing trend.The flow and pressure of the compressed air affect the temperature rise of the bearing through the convection heat of the compressed air and the bearing. Within the compressed air pressure range, the temperature rise of the bearing decreases with the increase of the pressure, but this trend is not very obvious.Increasing the compressed air flow can reduce the temperature rise of the bearing, and as the speed increases, the cooling effect will become more and more obvious.
