Q: How many times can heads be machined?
A: Cylinder heads can typically be machined multiple times, depending on the material and extent of the machining. For airsoft cylinder heads, machining is usually done once for precise fit and performance. Over-machining can reduce the head's structural integrity, so it's essential to follow manufacturer recommendations and ensure the head remains within tolerances.
Q: What is the job of a cylinder head?
A: The cylinder head in an airsoft gun plays a crucial role in sealing the compression chamber. It helps to channel the air from the piston to the barrel, ensuring efficient propulsion of the BBs. In real firearms, the cylinder head also houses the valves and provides a seal between the combustion chamber and the cylinder.
Q: What are the materials used in the manufacturing of cylinder head?
A: Cylinder heads for airsoft guns are commonly made from aluminum, steel, or durable polymer materials. CNC-machined cylinder heads are often made from high-grade aluminum for precision and durability. Real firearm cylinder heads can be made from various metals and alloys, including aluminum, steel, and cast iron.
Q: Why do cylinder heads fail?
A: Cylinder heads can fail due to several reasons, including material fatigue, improper machining, excessive wear, overheating, or damage from impacts. In airsoft guns, failure may occur due to incorrect fit, poor quality materials, or improper maintenance.
Q: Is it OK to reuse cylinder head bolts?
A: In many cases, it's acceptable to reuse cylinder head bolts if they are in good condition and have not been stretched or damaged. However, it's essential to check for any signs of wear or damage. In critical applications, such as in real firearms, it is generally recommended to use new bolts to ensure proper sealing and safety.
