It is reported that the SIEMNC802D numerical control system of the machine tool can realize the vertical and horizontal two-axis linkage of the grinding wheel frame, and the main grinding circle of each segment of the ball screw with a length of 10 meters and a diameter of 250 mm.
The successful development of the 10-meter CNC cylindrical grinding machine is of great significance for realizing the localization of major equipment and promoting the rapid and healthy development of Hanban's rolling functional components industry.
For a long time, due to various factors such as technology and equipment, the market of ultra-long and heavy-duty ball screws with high domestic value added has been basically occupied by foreign companies.
In recent years, Hanjiang Machine Tool Co., Ltd., one of the major manufacturers of domestic thread grinding machines and ball screws, has fully utilized the technological advantages accumulated by the company for many years, concentrated manpower, material resources and financial resources, and has successively overcomed the 10-meter CNC screw grinding machine and hard rotation. A number of key technologies in the milling process have become the first rolling functional parts manufacturer in China with a 10-meter CNC screw grinder and hard-spinning technology. It is understood that the 10-meter CNC cylindrical grinding machine is one of the main supporting equipment for the production of ultra-long and heavy-duty ball screws. Its successful development and production into the enterprise will rapidly improve the production capacity of China's large-scale high-precision ball screw. , making important contributions to the replacement of imports of domestic rolling functional components.
Electric valve is a device that drives the valve to open and close by electric motor. It is widely used in various industrial and civil fields, such as metallurgy, chemical industry, petroleum, natural gas, heating, ventilation and air conditioning, automatic control, etc. The following are some application scenarios of electric valves:
1. Fluid control in industrial production: electric valve can be used to control the flow, pressure and temperature of liquid, gas and steam to meet the needs of industrial production.
2. Oil and natural gas industry: electric valves can be used in oil and natural gas exploitation, processing, transmission and storage to control flow and pressure and ensure production safety and efficiency.
3. Chemical industry: electric valve can be used for fluid control in chemical production, such as acid-base solution, gas and liquid reactant control, to ensure the safety and efficiency of production.
4. Heating, ventilation and air conditioning system: the electric valve can be used to control the water flow, air flow and temperature in the heating, ventilation and air conditioning system to meet the requirements of the indoor environment.
5. Automatic control system: electric valve can be used with automatic control system to realize automatic control and adjustment of fluid flow, pressure, temperature and other parameters.
In short, electric valves are widely used in industrial and civil fields, which can improve production efficiency, ensure product quality and improve production safety.
