Gas lighting is production of artificial light from combustion of a gaseous fuel, such as hydrogen, methane, carbon monoxide, propane, butane, acetylene, ethylene, coal gas (town gas) or natural gas.The light is produced either directly by the flame, generally by using special mixes of illuminating gas to increase brightness, or indirectly with other components such as the gas mantle or the limelight, with the gas primarily functioning as a fuel source.Before electricity became sufficiently widespread and economical to allow for general public use, gas was the most popular method of outdoor and indoor lighting in cities and suburbs. Early gas lights were ignited manually, but many later designs are self-igniting.Gas lighting now is generally used for camping, where the high energy density of a hydrocarbon fuel, combined with the modular nature of canisters (a strong metal container) allows bright and long lasting light to be produced cheaply and without complex equipment. In addition, some urban historical districts retain gas street lighting, and gas lighting is used indoors or outdoors to create or preserve a nostalgic effect.

The times are changing. Increasing efficiency competition requires more efficient processing methods. In the entire large machine configuration, the cost of the tool is almost negligible, but the actual work must be done through the cutting of the blade. Although a blade is only a very small part of the overall machine price, it is because of the cutting process of the blade that the machine can operate effectively.
The pursuit of efficiency is the driving force behind the continuous development of the tool. The high feed milling (HFM) concept currently offered by Seco Tools is undoubtedly one of them.
Significantly improved efficiency
“This milling method can achieve three times faster processing efficiency than the traditional method.†Wang Hao, Marketing Department of Seco Tools (Shanghai) Co., Ltd. told the China Industry News that the key to achieving this effect is that the high feed is not cutting. The larger depth of cut is used, but in the opposite direction, the shallow depth of cut and the high feed per tooth are used in pairs, which not only protects the tool, but also achieves a higher metal removal rate.
Wang Hao had taught mechanical courses for 9 years in a university in Shanghai, so it is unambiguous to talk about theory. He told reporters that high feed milling has great advantages in metal processing. For example, the cutting force points in the axial direction towards the machine tool spindle, which reduces vibration and thus increases tool life. In addition, more than one thousand cubic centimeters of workpiece material can be removed per minute due to the smaller depth of cut and faster feed per tooth. In actual operation, the feed rate can sometimes be increased to ten times the normal value.
Since the high-feed roughing with a small depth of cut has produced a shape that is close to the shape of the final demand, even with the roughing method, the shape of the finished product can be obtained, and the semi-finishing can usually be canceled. CNC programming is therefore simplified, and the process does not require the machine to increase the speed. In this way, you can skip the semi-finishing and directly perform the final finishing. Each machine can produce more parts per unit time.
Wang Wei said that high-feed milling and long overhang have a very harmonious cooperation. Long overhangs with high feed tools for up to three times faster machining efficiency. Since the blade is designed to be triangular and the cutting edge has a very large arc, it is possible to achieve a small depth of cut and a high feed without vibration.
He believes that for most high feed milling, the triangular insert is actually better than the round insert. The reason is that the main cutting force is at the bottom of the cutting edge. Each of Seco's high-feed milling inserts has a strong geometric angle. The geometrical angle of the tool on the machine shows less tool change, less adjustment and lower machine downtime. This means maximizing the machining time of each machine.
Wang Wei said that although the blade is small, the technical content is not normal. The selection and determination of materials, coatings, and tool structures are not easy. The shop operator who is the end user is concerned with the efficiency of the tool. This requires the tool manufacturer to provide a full range of services. Therefore, in the tool industry, technology and services have always been equal.
Service first
Wang Wei told reporters that although the annual tool consumption of users only accounts for 3% of the total cost, its influence must account for 25%. Therefore, after the tool is sold out, the service process has just begun. A series of problems such as debugging, optimization and replacement of tools are expected to be addressed and solved by tool manufacturers. At this time, the concept of selling products and selling services obviously cannot cover the connotation of these jobs.
Different from other companies, Seco not only advances the concept of serving customers, but also infiltrates this process into the whole process of user processing and production.
With a reliable product foundation, it is also necessary to meet the needs of customers through a certain customer interface. The customer interface includes the service team, service methods and service means. Seco has always been committed to improving the service to its customers. After years of accumulation, it has established a strong sales, technical support, logistics and other teams. “However, the evolving customer needs will always push us to new and higher requirements.†Wang Wei said, “So, build a team that can listen, understand, and focus on customer needs, and provide solutions and a global network. Efficient and comprehensive customer interface is an important means to meet customer needs and provide value-added services to customers."
To establish an efficient and complete customer interface, we must abandon the backward sales methods based on products and prices, and transform existing systems. The goal of the transformation is to further strengthen communication with customers, timely understand and master customer needs, and provide timely and effective solutions and support solutions.
In the process of communicating with customers, Seco has truly felt that the market competition faced by customers is becoming increasingly fierce. Customers are also increasingly aware of the growing importance of tools in metal cutting. Because today is not the era of the special machine production line oriented by the user-end process, the processing technology is shifting to the direction dominated by flexible production lines (CNC machine tools) and CNC tools. The position of cutting tools in metal cutting is becoming more and more important. To improve productivity and reduce production costs, enterprises must rely on high-efficiency cutting tools and efficient machining processes.
At the top of the high-value pyramid model is “participationâ€. When Seco goes from tool supplier to tool system supplier to machining overall solution provider, the relationship with customers will gradually change from external supplier to customer partner. Therefore, “participation†is to establish a strategic alliance relationship with customers, and to take the customer's goal as their goal. In the whole process from design to manufacturing, we provide customers with various process solutions to improve production efficiency for customers. Reduce manufacturing cost services. Only by interacting with customers and helping our customers improve their competitiveness can we truly achieve their own competitiveness and market share, and ultimately achieve a win-win situation.
