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

The effect of oil-air lubrication on the performance of electric spindle

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 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 has become the key to solving the problem.practice shows that,Oil-air lubricationThis situation can be avoided fundamentally.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.

DopsyElectric spindle oil-air lubricationIt 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. Modular structure, module components can be increased or decreased 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 lubricationThe equipment is easy to operate and use, and the maintenance cost is low.
DopseyElectric spindleOil-air lubricationThe device has: oil supply, parameterized operation, simple operation, and 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.
