With the rapid development of the automotive industry, efficient, high-precision, and high-stability machining of complex major automotive parts is an effective way to shorten product production cycles and improve enterprise efficiency and competitiveness. CNC machining technology makes producing and manufacturing rapid prototypes of complex automotive parts possible. At the same time, virtual manufacturing technology, flexible production technology, and CNC technology integrated manufacturing technology is widely used in modern automotive processing and manufacturing. The intellectual development of CNC manufacturing technology in the manufacturing process of auto parts will become the development trend of the auto manufacturing industry.

Why is CNC custom machining technology important for high-precision cylinder parts?

Accuracy is key for high-performance engines. The cylinder is one of the most important parts of any engine. The engine chamber is where the fuel is burned, generating the vehicle’s power. The ability of an engine to run smoothly and efficiently depends on whether the cylinder parts are produced using a high-precision manufacturing process.

In the past, cylinder parts were manufactured using traditional methods, such as casting and forging. While these methods are still used today, they have some limitations regarding precision and accuracy. CNC custom machining technology has revolutionized the way cylinder parts are manufactured. CNC machines are ideal for manufacturing high-precision automotive engine cylinder parts today as they can produce complex shapes and intricate designs with extremely high precision. This is especially true for customized high-performance automotive engine parts.

With CNC technology, cylinder parts can be manufactured to extremely tight tolerances, ensuring a perfect fit and high performance. CNC machines can also produce complex shapes and designs that conventional methods cannot. This means that manufacturers can create custom-designed cylinder parts to meet the specific requirements of a particular engine.

Automotive engine block 5-axis CNC machining process

An automotive engine comprises two main components, the cylinder block and the cylinder head, which are bolted together. The cylinder block material should be made of aluminum alloy. Because the aluminum alloy cylinder block is lightweight and has good thermal conductivity, sufficient strength, good castability, and machinability.

The main machining surface of the cylinder block has ten: front and back, above, below, bearing upper cover seating surface, crankshaft semicircular surface, crankshaft support surface, cylinder bore, crankshaft bore, reference surface, and reference hole. The cylinder body structure shape is complex and difficult to process; to ensure accuracy and efficiency, we choose a high-precision five-axis CNC machining center for aluminum alloy cylinder body processing.

Five-axis CNC machining cylinder block of the main processes are: crankshaft bore semicircular surface rough and finish boring, determine the axial width rough and finish boring processing, determine the width of the journal parts on both sides of the milling, the third bearing surface rough and finish machining, bearing surface oil groove processing back and forth, cylinder bore rough boring, cylinder bore internal chamfering processing, the upper and lower rough and finish milling, front and rear rough and finish milling, moving with reference surface milling, bearing cover seat rough and finish milling, cylinder bore crankshaft bore reference hole Machining.

When five-axis machining, we should consider chip discharge to ensure that there is no chip residue on the machining surface and use wear-resistant high carbide inserts to obtain a high brightness and high surface finish. The cutting edge is chamfered to prevent chipping of the cutting edge and damage to the surface. When boring, the boring bar is equipped with carbide to inhibit workpiece deformation.

What can automotive parts be machined by CNC?

Today’s CNC machines include 3-axis and 5-axis machining and turning with power tools. These features provide more ways to manipulate and maneuver material in the machine, so not only can curves be trimmed rather than right angles, but they are often more complex and can produce good results. Not surprisingly, this has led to many applications, including some critical automotive parts. Two main categories of parts can be machined by cnc today.

Automotive parts such as engine blocks, cylinder heads, rotary shafts, drive shafts, gears, gearboxes, brake drums, wheel hubs, gear rockers, rocker shafts, and other parts with complex curved surfaces.

Motorcycle parts include the oil pump housing, oil pump cover, left and right crankcase, cylinder block, cylinder head cover, oil plug, case, rocker arm shaft, and other parts.

What materials and surface treatments are available for CNC machining auto parts?

The internal structure of the car is very complex; to ensure its strength, electrical and thermal conductivity, wear resistance, weight reduction, and other requirements, different parts need to be processed with different materials; CNC machining of automotive parts commonly used materials are: aluminum alloy, zinc alloy, magnesium alloy, stainless steel, steel, etc., but also according to different processes and materials customize a variety of surface treatment, such as anodic, powder coating, painting, sandblasting, electroplating, electrophoresis, laser engraving, silk-screen printing, polishing, etc.

Conclusion

In summary, CNC custom machining technology has revolutionized the manufacturing of high-precision automotive engine cylinder parts. The ability to produce custom-designed parts with superior precision and accuracy has made CNC machines an essential tool for the automotive industry. The benefits of CNC technology include precision, efficiency, customization, quality, versatility, and consistency. With its wide range of applications, CNC custom machining technology is expected to play a key role in the future of high-performance engine manufacturing.
