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 importance of choosing oil-air lubrication for high-speed bearings

The electric spindle runs at a high speed, and the good lubrication of the bearing is an important index to ensure its normal operation. Therefore, matching a suitable electric spindle lubrication system is very important.

The lubrication-related factor that affects the running accuracy of the electric spindle is the heating of the electric spindle. The internal heat source of the electric spindle comes from two aspects: 1. The heating of the spindle bearing; 2. The heating of the built-in motor of the electric spindle.

To solve the heating of the motor, the stator of the motor needs to be cooled, which can be achieved by circulating water cooling to take away the heat of the motor; to solve the problem of heating of the spindle bearing, it is necessary to remove the heat generated by the bearing operation in time. Traditional thin oil lubrication is to transport a large amount of lubricating oil to achieve intrusive lubrication. At the same time, the lubricating oil takes away the heat. This kind of lubrication method has disadvantages. First, it wastes a lot of lubricating oil. Second, the friction between the lubricating oil molecules and the pipeline during the cycle of lubricating oil generates a lot of circulating heat, which causes the oil temperature to rise. At this time, the lubricating oil Not only can it not have a good cooling effect, but it will also cause the temperature of the bearing to rise, which is not conducive to the performance of the spindle bearing. Therefore, eliminating the generation of frictional heat between molecules in the liquid becomes the key to solving the problem. Practice has shown that Oil-air lubrication can fundamentally avoid this situation. First of all, oil-air lubrication provides a small amount of lubricating oil to meet the amount of lubricating oil required by the bearing. Secondly, oil-air lubrication will not produce heat due to friction of lubricating oil molecules, and at the same time, clean compressed air will take away the heat generated by the bearing and keep the spindle running at a stable temperature. This can effectively solve the problem of thermal deformation caused by temperature rise.

Doppel has been committed to the research on oil-air lubrication of electric spindles for many years. It has mature oil-air lubrication products and rich application experience, which will bring greater value to customers.

Doppel’s electric spindle oil-air lubrication has the following advantages:

1,
A positive pressure environment can be obtained in the bearing chamber of the electric spindle to prevent the intrusion of external impurities.

2. Compressed air can have a good cooling effect on the bearing.

3,
1-8 independent lubrication points can reliably monitor the oil supply of each lubrication point.

4. The consumption of lubricating oil is controlled by metering, so the consumption is very low.

5,
The modular structure can increase or decrease the module components according to the number of lubrication points to realize multi-point combination;

6. Fully electronic program control, quick setting through convenient man-machine interface;

7, Oil-air lubrication equipment is easy to operate and use, and the maintenance cost is low.
Doppel Electric spindle Oil-air lubrication device has: oil supply, parameterized operation, simple operation, the system realizes the monitoring of liquid level, air source pressure, and flow output. At present, it has been used as a supporting tool for many home appliance spindle manufacturers.
