Nodular cast iron cutting equipment for cylinder cover
Technical Field
The invention belongs to the technical field of cylinder cover machining, and particularly relates to nodular cast iron cutting equipment for a cylinder cover.
Background
An internal combustion engine includes a cylinder head. The cylinder head is a metal part of the engine that surrounds and covers the cylinder. The cylinder head is typically removable and contains components such as valves, valve seats, and other components (e.g., coolant circulation). The cylinder head helps to keep the engine cool when exposed to mechanical and thermal loads. Therefore, there are high mechanical requirements for the cylinder head member and the cylinder head material. Nodular cast iron is an important raw material of a cylinder head due to excellent mechanical properties and heat resistance. When the nodular cast iron is processed into the cylinder cover, the nodular cast iron needs to be cut, and due to the excellent mechanical property of the nodular cast iron, the cutting precision is difficult to meet.
