Automotive engine parts processing tool scheme

The engine is responsible for generating the power needed to move the vehicle. Today, in the need to reduce emissions and improve power efficiency, the development of engines is increasing.

New materials, regulations, and other drivers have brought a lot of investment into research and development. The main trend is the miniaturization of internal combustion engines in order to minimize environmental impact. Another development trend is powertrain electrification.

Tesa Precision solutions and tools for engine parts are backed by in-depth application expertise. With a dedicated engineering team that supports the automotive industry with a wide range of quality solutions, we also have a presence on the international market. Here, we will share selected high-productivity solutions for some of the challenging features in engine parts production.

Cylinder block

The cylinder block is the main structure that acts as the engine, it is the housing of a number of different moving parts that together produce the power required for vehicle movement.

The cylinder block is the part that acts as the main structure of the engine, it is the housing of a number of different moving parts that together produce the power required for the movement of the vehicle.

For many years, engine blocks have been made of cast iron alloy because of its high strength, low cost and good wear resistance. However, as engines have become more complex, new materials have been introduced to reduce engine weight and improve strength and wear resistance. Today, the most commonly used material for passenger car engines is aluminum alloy, due to its lighter weight and excellent casting properties. Commercial vehicles will continue to use cast iron, but more high-strength alloys.

The manufacturing process of the cylinder block involves the largest number of machine tools in the production of automotive parts, as well as several complex processes and tight tolerances. The high quality of the cylinder block is essential to the performance of the vehicle. For these types of parts, economical manufacturing is very important.

Cylinder head
The cylinder head transmits air and fuel to the combustion chamber and plays the role of covering the cylinder. It is also a housing for many different parts.

The cylinder head is used to transport air and fuel to the combustion chamber, and because it is located on top of the cylinder block, it acts as a cover for the cylinder. It is also the housing for many different parts such as valves, spark plugs and fuel injectors.

In addition to the cylinder block, the manufacturing process of the cylinder head also involves the largest number of machine tools in the production of automotive parts. In addition, several complex processes and tight tolerances are involved, especially when machining the valve seat and valve guide as well as the top surface. Since the cylinder head is an important part of the engine, its quality is crucial to the performance of the vehicle. For these types of parts, economical manufacturing is also very important.

Crank shaft

This part is used to convert linear motion and power into rotational motion to make the shaft rotate and thus the vehicle move.

The asymmetrical and relatively slender crankshaft forms the heart of the internal combustion engine in all vehicles, from motorcycles to heavy trucks. It is also one of the most challenging parts to process. Considering the structure of the crankshaft, the high tolerance requirements, and the challenging machinability of the material (forged steel or ductile iron), only the use of truly optimized tools and methods can be successful.

Camshaft

The camshaft is used to control the valve operation, thus synchronizing the combustion cycle.

In internal combustion engines, camshafts are used to control valve movement and synchronization. It consists of a shaft with multiple CAM lobes, one camshaft for each valve. The CAM blade exerts pressure on the valve (or some intermediate mechanism) as it rotates to force the valve open.

Connecting rod

The connecting rod is used to transmit linear motion from the piston to rotate the crankshaft.

The connecting rod is used to transmit linear motion from the piston to rotate the crankshaft. It is under tremendous stress from reciprocating loads, stretching and compressing with each rotation. The reciprocating load increases square with the increase of engine speed. Unlike the earlier methods of cutting with a milling cutter, the large end is now usually cracked. When cracking the large end, it may be necessary to preprocess a laser crack, which puts high requirements on the subsequent boring process.

The connecting rod manufacturing process must be precise in terms of important tolerances and at the same time must be highly economical.
