Titanium is currently favored for its excellent weight-to-strength ratio (3 times that of steel), corrosion resistance, histocompatibility, and excellent high temperature performance. Aerospace titanium machin ing  parts  are particularly popular because they are lightweight and strong. However, there are many difficulties in titanium machining, here are 7 points why titanium machining is so difficult.   1. Titanium maintains high strength even at high temperatures and its resistance to plastic deformation even at cutting speeds. This enables far greater cutting forces than any steel. 2. When the chip is formed, it is very thin, and the contact area between the chip and the tool is three times smaller than that of steel. Therefore, the tip of the tool must withstand almost all cutting forces. 3. Titanium alloy has a high friction coefficient for tool materials. This increases cutting temperature and force. 4. Titanium reacts chemically with most tool materials at temperatures over 500

  The radiator cap is an essential part of a car's safety and proper operation, but it is also often the cheapest and most overlooked part of the cooling system. The radiator cap acts as a pressure relief valve, dumping hot fluid and reintroducing cold fluid, maintaining optimum pressure and temperature within the cooling system. Next, let me talk about what exactly the radiator cap does. 1. Prevent overheating Car radiator cap s maintain a certain pressure inside the cooling system and raise the boiling point of the coolant. You may be wondering why the system needs to maintain pressure. In fact, as the coolant expands as it heats, the size of the system cannot be changed and it will only increase the internal pressure. Each additional pound of pressure increases the coolant's boiling point by 2-3 degrees, which will effectively prevent the coolant from boiling and prevent the cooling system from overheating. 2. Allow coolant to flow The radiator cap has a vacuum valve that al
