On January 26th, the domestic retail price of refined oil products ushered in a new round of adjustment window. "Economic Information Daily" reporter learned from a number of social monitoring agencies, the current measurement range of 50 yuan / ton near the red line, is expected to be stranded or slightly increased.
Recently, international oil prices have been at a high level of turmoil. Brent has shifted downwards after he has soared $70/barrel. Although the U.S. crude oil production showed signs of recovery, many oil-producing countries successively expressed their determination to reduce production. This gave the bulls a "tenting pill." In addition, stocks continued to decline, the International Monetary Fund raised its global economic growth forecast and the dollar fell below the 90 mark. These factors provide the oil market with strong underlying support.
As of the close of January 23, the light crude oil futures prices for March delivery on the New York Mercantile Exchange rose 0.90 US dollars to close at 64.47 US dollars per barrel, an increase of 1.42%. London Brent crude oil futures for March delivery rose by 0.93 U.S. dollars to close at 69.96 U.S. dollars, an increase of 1.35%.
China's "Administrative Measures on Oil Price" stipulates that domestic gasoline and diesel prices should be adjusted every 10 working days according to changes in crude oil prices in the international market. The effective date of price adjustment is 24 hours on the date of price adjustment. When the price adjustment rate is lower than 50 yuan per ton, no adjustment will be made and the cumulative or offset will be included in the next price adjustment.
On January 24, Beijing time, Zhongyu Information estimated that the crude oil change rate was 2.7%, and Zhongyu crude oil was valued at 66.673 US dollars/barrel, which was an increase of 1.751 US dollars/barrel from the benchmark price. It is temporarily expected that the zero limit price of refined oil will be raised at 24 o'clock on January 26th. 60 yuan/ton. Jinlianchuang and Longzhong Information estimated that the price of gasoline and diesel will be increased by RMB 55/t, and the new round of refined oil price adjustment window will be opened at 24:00 on January 26. However, Zhuo Chuang Information Oil Product Analyst Zhang Yuxin believes that the current round of oil price increase is likely to be less than 50 yuan/ton, so this round of refined oil retail price adjustment may achieve the first time during the year.
Zhongyu Information Analyst Ma Jiancai said that after the market outlook, international crude oil still has downward pressure, and the domestic market's current round of retail prices may still be raised or stranded. With the end of the year, end-users will start or will continue to reduce, resulting in further reduction of diesel demand, the operators enter the market operation is limited, the high inventory manufacturers do not rule out continue to increase promotional efforts. With the gradual arrival of the Spring Festival holidays, the demand for petrol is relatively strong. Some companies are preparing goods in advance. It is expected that domestic gasoline will be better than diesel in the short term.
CNC Milling Machine is an automatic processing equipment developed on the basis of general milling machine.The processing techniques of the two are basically the same, and the structure is somewhat similar.CNC milling machines are divided into two categories: without a tool magazine and with a tool magazine.The CNC milling machine with a tool magazine is also called a machining center.
Features
In addition to the characteristics of ordinary milling machines, CNC milling has the following features:
1.The parts are highly adaptable and flexible, and can process parts with particularly complicated contour shapes or difficult to control dimensions, such as mold parts and shell parts;
2.It can process parts that cannot be processed or difficult to machine with ordinary machine tools, such as complex curve parts and three-dimensional space surface parts described by mathematical models;
3.Parts that can be processed in multiple processes after being able to process a single clamping position;
4.The processing precision is high, the processing quality is stable and reliable, the pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1μm. In addition, the numerical control processing also avoids the operator`s operation error;
5.High degree of production automation, can reduce the labor intensity of the operator. Conducive to the automation of production management;
6.High production efficiency. CNC milling machines generally do not need special process equipment such as special fixtures. When replacing workpieces, it is only necessary to call the machining program, clamping tool and tool data stored in the numerical control device, thus greatly shortening the production. cycle.
Secondly, the CNC milling machine has the functions of milling machine, boring machine and Drilling Machine, which makes the process highly concentrated and greatly improves the production efficiency.
In addition, the spindle speed and feed speed of the CNC milling machine are infinitely variable, so it is beneficial to choose the best cutting amount.
