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

Mini Lubrication Application of Vertical Car

&nbsp;Minimum lubrication is used in vertical lathe processing in two application forms: external spray type and internal cooling type. <br /> &nbsp;&nbsp;&nbsp; The external spray type micro-lubrication is easy to install, as long as it does not affect the processing and the movement of other parts, it can meet the requirements. <br /> The internal cooling type micro-lubrication is that the lubricant is sprayed to the cutting area in the form of suspended oil mist particles. The key to this is to maintain the reliable flow of suspended particles. Therefore, the structure of the machine tool should be designed to ensure the transportation and transportation of suspended particles. The sealing of the channel is reliable, and the optional fixture and cutting tool should be matched to ensure that the lubricating oil mist particles can reach the cutting area. <br /> &nbsp;&nbsp;&nbsp; Vertical lathes can be used with internal cooling type micro-lubrication and external cooling type micro-lubrication. The micro-lubrication system can be equipped according to the specific conditions of the machine tool. Most vertical lathes do not have internal cooling channels, so external nozzles are often used to deliver MQL oil mist to lubricate the cutting area of ​​the cutting tool. The following is a brief description of its characteristics: <br /> &nbsp;&nbsp;&nbsp; When the lubrication device receives the processing signal, the injection system enters the working state, the lubricating oil is supplied by the micro pneumatic lubrication pump at the set frequency, and the spray is formed at the nozzle The oil mist particles reach the surface of the workpiece. The compressed air at each lubrication point is kept in a constant supply state. When the processing is completed, the lubricating device is powered off and stops working at the same time. The oil supply frequency is adjusted according to the oil film formed in the injection area as the standard. <br /> &nbsp;&nbsp;&nbsp; The system low liquid level monitoring can give an alarm when the oil level is low, and remind the maintenance personnel of the lubrication system that the oil needs to be added. The low liquid level alarm signal can be linked with the machine tool alarm system. <br /> &nbsp;&nbsp;&nbsp; The external spray type lubrication adopts precise metering micro-lubrication technology, which saves oil consumption, and reliably sprays the lubricating oil on the surface of the workpiece and cutting tool in the form of tiny oil mist particles at the terminal. Lubricant film. <br /> 1. Jet-type lubrication can save a lot of oil consumption without causing waste. <br /> 2. Lubricating medium consumption is low, measured in ml/h units; <br /> 3. Oil quantity is accurately measured and supplied accurately; <br /> 4. The system has few moving parts, reliable operation and small maintenance ;<br /> 5. The oil and gas pipeline layout is simple, easy to install and maintain. <br />
