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 rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

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 />
