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

Analysis of Cylinder Block Casting Process

The foundry of Nanjing Automobile Parts Factory (now Nanjing Automobile Factory) was originally the foundry of the general repair and parts factory of a unit. There are teams of melting, core making, styling and copper parts, which produce component blanks for repairing ordnance and auto parts such as pistons, piston rings and bearing bushes. In 1951, the factory cooperated with Beijing Auto Parts No. 5 Factory to trial-produce the Jinggangshan brand motorcycle treadmill; in 1953, it began to produce cylinder heads and cylinder liners and other auto engine parts. The equipment used included melting rate cupolas, sand mixers, and centrifugal casting Simple equipment such as machine, copper furnace and hand crane; in 1956, the factory began trial production of the M20 engine.

is a thin-walled cylinder block casting. Under the conditions at that time, the five-box manual assembly group casting process was adopted. By adopting the vertical casting process, the casting defects such as shrinkage, pores and slag inclusion in the castings were solved, and the production capacity of 20 cylinder block castings was formed. The application research of ductile iron in China began in the early 1950s. On the basis of popularizing the application of dense-baked cast iron, the foundry workshop of Nanjing Automobile Parts Factory uses magnesium silicate or copper-magnesium alloy as a nodulizer to trial production of ductile iron parts, setting a precedent for the application of ductile iron in automobile casting parts in China. At that time, the spheroidizing alloy was placed in the cupola tapping trough and flushed into the molten iron ladle with the flow to achieve the purpose of spheroidizing the molten iron.

The cast castings are cylinder liners and fixtures; in 1955, the factory trial-produced nodular cast iron crankshafts, which was a new way of producing automobile crankshafts in China by “substituting iron for steel and casting for forging”. The foundry of China Casting Machinery Nanjing Automobile Parts Factory was an automobile foundry that developed early on relying on self-reliance in the early days of the founding of the People’s Republic of China. Its completion marked the beginning and beginning of China’s automobile casting production and technology.
