Owners of high-altitude vehicles with smoking habits often carry lighters with them. If you, like Mr. Zhang, forget to take the lighter out of the car during a hot day, then a lighter explosion may occur at any time. Once it explodes, the resulting flames come in contact with flammable substances and may even cause spontaneous combustion of the lift truck . It should be noted that there are many spontaneous combustion phenomena caused by the explosion of a lighter in the car. In addition, flammable and explosive materials such as perfume bottles, sealed beverages and sprays are also the main culprit, especially in the case of high-temperature exposure, the possibility of such items exploding is very high. Relieve the crisis: Remind those careless car owners to check whether there are such dangerous goods left in the aerial vehicle before getting off the train. Aerial boom crisis Xiao Xu, the owner of the aerial vehicle, walked down in the scorching sun. Suddenly, he noticed a problem in the rear wheel. Many years of driving experience told him that the wheel was punctured. He slowly parked his car behind the speed bump and called the trailer. Xiao Xu's approach is very correct. He must not step on the brakes after finding a puncture, and should stop the car after slowing down. There are many reasons for causing a flat tire, especially in the summer, because the conditions for using the tire are worse than before, and the possibility of a flat tire is even greater. Relieve the crisis: Remind those owners who have been working long hours in the hot sun to try to control travel time and avoid high temperatures. If you need to drive in the hot sun for a long time, then allow the vehicle to cool down at regular intervals, and avoid using cold water to rush the truck and tires that have just been exposed . In addition, regular inspection of the tires is also very important.
The CNC milling process is a digital manufacturing process that is implemented by computer numerically controlled (CNC) machines. This process is used to produce parts with complex shapes, and the manufacturing process involves multiple steps. The following are the detailed steps of the general CNC milling process:Design: First, you need to design a CAD model of the parts you want to produce. A CAD model is a three-dimensional image created using computer-aided design software that can describe the shape, size, and features of a part.Programming: Next, you need to convert the CAD model into G-code, which is a type of computer instruction that controls the movement and operation of the CNC machine. G Code can be written manually or generated automatically using CAM software.Prepare the machine: Before you start machining, you need to check and prepare the CNC machine. This includes checking the machine's coordinate system, setting tools and cutters, and setting parameters such as the machine's speed and feed speed.Processing: After the machine is ready, the processing can begin. The machining process usually consists of multiple steps, such as roughing, finishing and drilling. At each step, the CNC machine moves tools and workpieces according to instructions in the G code to achieve the desired cutting operation.Inspection: After processing, the parts need to be inspected to ensure that they meet the design requirements and specifications. Inspection can be carried out by using measuring instruments, templates and other testing tools.Polishing and surface treatment: Parts can be polished and surface treated if needed to improve their surface finish and corrosion resistance. This can be done through the use of abrasives, chemicals and other tools.In short, the CNC milling process is a high-precision, high-efficiency manufacturing process for the production of parts with complex shapes. Through the control of CAD model and G code, the precise control of machine motion can be realized, so as to achieve high-precision parts processing.

What are the risks of high-altitude aerial vehicles in summer hot weather?
When the driver of the aerial vehicle gets off the vehicle, he places the lighter on the instrument panel. After returning for two hours, I discovered that the lighter above the instrument panel had been burned to pieces.
