Engine parts
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.
Technical Characteristics
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.
