With the full implementation of the State Five Fuel Standard, the corresponding State Five mobile oil tanker chassis manufacturers have also made an upgrade schedule. The upgraded mobile tanker has not changed substantially from the previous one, but the price has increased substantially. So what caused the rise in the price of mobile tanker trucks? Let's take a look at the views of some businesses. The first is the increase in the cost of car purchases for mobile tankers. Because the national five standards for emission of exhaust gas are more stringent than the previous national four standards, so the overall configuration of the car is higher than that of the national four, resulting in higher operating costs for manufacturers, and thus the price of mobile tank cars. Nature also improves. Not only does the price of mobile tankers increase, such as when customers purchase chemical vehicles, refrigerated trucks, liquefied gas tankers, and other special vehicles, the price of the National Five-Series vehicles is higher than that of the National Fourth-series. Take 14.1 cubic meters of sulfuric acid chemical transporter as an example. The 155-kilowatt engine is sold at a price of 193,000 in the country's four-car chassis, and the country's five-car chassis is priced at about 205,000. This was followed by the higher purchase tax and fuel cost of the State V fluid tanker . As the increase in the price of vehicles leads to an increase in purchase tax, it also increases the cost of car purchases. In addition, the national five-engine has higher fuel quality requirements. Because the better the fuel quality, the higher the price, the higher the corresponding fuel cost. The last is the increase in the use of urea. Since the exhaust gas emission standards of the State V fluid tankers are more stringent than those of the Nation IV, the corresponding costs are higher than the previous ones in order to reduce the emissions of tail gas, which leads to an increase in the use of vehicle urea. Another point is that the configuration and after-sales service provided by each merchant is different, so the corresponding quotes for the mobile tanker will be different, so these are the factors that affect the price of the tanker.
High Precision Machining is defined as a process of changing the dimensions or the performance of workpiece with machining facilities.
According to the temperature of the workpiece while in machining, high precision machining can be divided into cold working and hot working. Usually, machining under indoor temperature, and won't change cause chemical change or phisical phase change is named cold working. On the other hand, if under temperature, higher or lower than room temperature, which will lead to chemical changes or phase changes, it will be called as hot working.
For high precision machining, the machining tolerance can be up to 0.0001-0.001mm, the surface finish Ra can be 0.02-0.1um.
Machining precision is to describe the actual geometrical parameter of the part after machining, such as the size, the form, the position, comparing with the theoretical geometry parameter. The difference from these two parameters is the machining tolerance. The number of the difference show the machining accuracy, the bigger, the lower of the machining precision, the smaller, the higher machining precision.
