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

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

Precautions for the selection of oil and gas lubrication products for high-speed electric spindles

High-speed electric spindles are currently mainly used in high-speed engraving and milling machines and grinders. The reliable guarantee of high-speed operation of electric spindles and the choice of products are particularly critical. The current lubrication methods are divided into: grease, oil mist, and oil and gas. Grease-lubricated electric spindles are not high in speed, and all bearings are packaged when they are selected. For high-load electric spindles, this lubrication method is both advantageous, and the advantage is that the investment cost of electric spindles is low. Oil mist lubrication: In fact, when the electric spindle is designed with only one lubrication inlet, this lubrication method is not conducive to the reliable and effective supply of lubrication, excessive consumption of oil and the risk of pollution to the operating environment. The economic cost is not good. Oil-air lubrication: Due to the obvious advantages of oil-air lubrication, current electric spindle design manufacturers generally adopt it. Let me talk about the requirements for oil and gas lubrication of electric spindles: 1. Lubricant cleanliness grade: 13/10 (ISO4406);

2. Air cleanliness: the air filtration accuracy is 0.01 micron;

3. Air dryness: dew point is +2℃;

4. The inlet gauge pressure in front of the bearing nozzle: 2-3bar;

5. Oil and gas pipeline: the inner diameter is 2 to 2.5mm, and the transparent pipeline with small bending radius is not easy to bend;

6. The length of the oil and gas pipeline: the ideal length is 1 to 4 meters. The spiral pipe at the distance from the terminal lubrication point is conducive to oil storage. When the bearing stops and runs again, it is helpful for the oil and gas to be in place quickly and shorten the response time. So when choosing oil and gas lubrication products, you must first meet the above requirements. In addition, the performance of oil and gas lubrication products can achieve good oil and gas transmission to the electric spindle and achieve reliable and stable operation.

1. Precisely quantified oil, and the amount of oil delivered to each lubrication of the bearing end can be adjusted arbitrarily, ranging from 5-40mm3.

2. Digital display time setting: It can realize the arbitrary setting of the oil supply cycle time.

3. Pressure monitoring: It can monitor the oil and gas delivery pressure or the gas source pressure, with priority to monitor the oil and gas pressure.

4. Oil supply status monitoring: As the amount of oil supplied per unit time of the electric spindle is small, and the interval of oil supply is 3min-7min, or even longer, the stability test of each lubrication point each time is an important indicator.

5. Bearing cavity pressure: the oil and gas pressure should be adjustable and set.

6. Display and fault feedback: The operating status of the product and the faults that appear have local display and remote feedback functions, such as: high or low air pressure failure, low liquid level, oil supply failure, etc. The above points are the guarantee to ensure the stable and reliable operation of the electric spindle. Therefore, it is necessary to carefully select suitable products when selecting oil-air lubrication. <br />
