Engine parts in the engine block is a more complex structure of spare parts box, Cnc machining its high precision, processing, complex process, and the processing quality will affect the overall performance engine, so it has become the engine manufacturer's focus parts one.
Engine block is the basic engine parts and skeleton, when the general assembly of the base components.Cylinder's role is supporting and ensuring the piston, connecting rod, Cnc machining crankshaft and other moving parts work, the exact location; to ensure the engine ventilation, cooling and lubrication; to provide a variety of auxiliary systems, components and engine installation.
Cylinder cast for a whole structure, and its upper part 4 cylinder mounting hole; cylinder standard cylinder is divided into upper and lower divisions into two parts; cylinder to the rear of the front-side arrangement of the previous three coaxial mounting hole of the camshaft and the idler axle hole.
Cylinder process features are: the structure of complex shape; processing plane, more than holes; uneven wall thickness and stiffness is low; processing of high precision typical of box-type processing part.
The main processing of the surface of cylinder block top surface, the main bearing side, cylinder bore, the main and camshaft bearing bore holes and so on, they will directly affect the machining ccuracy of the engine assembly precision and performance, mainly rely on precision equipment, industrial fixtures reliability and processing technology to ensure the reasonableness.
Technology program is the preparation of the master process is to process planning and key process equipment design guidance documents. Cnc machining The correct process of program design, facilitate the systematic application of new scientific and technological achievements and advanced production experience, to ensure product quality, improve working conditions, and improve process technology and process management level.
