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

Use AC oil pump to circulate and flush lubricating oil and speed regulating oil system

Commissioning of the oil system. The oil circulation of the lubricating oil and regulating oil system. After the installation work of the turbine oil system is completed, the main fuel tank of the turbine is thoroughly cleaned, all the throttle orifices on the oil system are removed, and the power oil pipes, Short-circuit the control oil pipe with the oil return pipe, and short the pressure oil pipe of the steam extraction check valve with the oil return pipe. After completing the above temporary measures before flushing, replenish new oil to the main oil tank to the normal oil level. Then start the AC oil pump, and after the trial run is qualified, use the AC oil pump to cyclically flush the lubricating oil and the speed regulating oil system. The circulating flushing of the oil system is carried out in two steps. **Step by pressing the mechanical handle of the manual brake and stop on the machine head side, thereby cutting off the system’s oil supply to the speed control system, that is, the speed control system is isolated, and the AC oil pump is used to circulate the lubricating oil system until the oil The quality has passed the laboratory test. The second step is to install a blocking plate at 517mm of the power oil pressure and lubricating oil pressure distribution throttle orifice to isolate the lubricating oil system, and lift the mechanical handle of the manual brake on the side of the machine head to supply oil to the speed control system. , The oil circuit of the regulating oil system and the steam extraction check valve is cyclically flushed until the oil quality is qualified, and the oil quality* finally reaches the US MOOG four-level standard.

Setting of the oil system safety valve and spill valve After the oil system cycle is flushed, the system is restored to perform the setting of the oil system safety valve and spill valve. First put in the electric heating device of the oil tank to heat the oil temperature to about 40e, then start the AC oil pump, pass the adjustment bolt on the safety valve through the Northeast Electric Technology, set the operating oil pressure value of the oil system safety valve to 2MPa, and then pass it on the oil spill valve. The adjustment bolt of the oil spill valve sets the operating oil pressure value of the spill valve to 118MPa. The adjustment of the lubricating oil pressure and the power oil pressure is through the combined adjustment device of the power oil pressure and the lubricating oil pressure on the top of the oil tank, and the power oil pressure is adjusted to 1165MPa, the lubricating oil The oil pressure of the oil supply pipe is adjusted to 0135MPa, and the power oil pressure and lubricating oil pressure are combined adjustment device. The size of the throttle orifice at the oil inlet of each bearing bush is provided to adjust the oil pressure and oil intake of each bearing bush.
