How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

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

Explore the lubrication methods of electric spindle bearings

Effectively controlling the temperature rise of the high-speed rotating electric spindle bearing is a very important indicator of the electric spindle, and the temperature rise of the spindle is closely related to the bearing. The method to reduce bearing temperature rise is:
(1) Reduce the dynamic friction of the bearing;
(2) Adjust and improve the heat dissipation environment of the bearing.
Commonly used electric spindle lubrication has the following methods:<br />
1. Grease lubrication<br /> &nbsp;&nbsp;&nbsp;&nbsp; Under normal circumstances, the heat per unit time of the bearing increases as the temperature rises, and the viscosity of the lubricating oil will decrease accordingly. In order to avoid overheating and injury of the bearing, it is necessary to fully add lubricating oil. However, the increase in oil volume also increases the resistance of stirring and increases the dynamic friction loss, thereby increasing the resistance of the electric spindle. If a small amount of grease is used for lubrication, not only will it not achieve the purpose of low friction, it will also not bring out the heat of the bearing. The high-speed rotation of the high-speed electric spindle accelerates the deterioration of the grease and reduces the service life of the grease. <br />

2. Oil mist lubrication The temperature of the bearing increases the service life of the electric spindle. Another advantage is that due to the oil mist lubrication of the electric spindle, the inside of the bearing seat has a certain air pressure, which avoids the damage of the electric spindle caused by the abrasive particles entering the shaft shell of the electric spindle. However, oil mist lubrication has problems of environmental pollution and inaccurate oil control. <br />

3. Oil-air lubrication<br /> Oil-air lubrication has the following characteristics:<br />
(1) A very small amount of lubricating oil can be continuously and stably supplied to the bearing;<br />
(2) Less environmental pollution. After placing the oil-air-lubricated electric spindle in a propylene box for about 2 hours, the air pollution level in the measuring box is about 0.03 mg/m. Pollution is less than that of oil mist lubrication. The reason is that oil-air lubrication has less oil than oil mist lubrication, and the lubricating oil and compressed air flow into the bearing in two phases. <br /> (3) It is difficult for dust or moisture and cutting fluid to enter the electric spindle bearing. The compressed air keeps the inside of the electric spindle bearing positive pressure. <br />
