Engine Parts Polishing

Automobile engine as the core component of the car, its performance is directly related to the car's power, economy and environmental protection. The Polishing process of engine parts is a key link to further improve the performance of the engine. In this paper, we will elaborate on the concept, importance and process of polishing automotive engine parts.

First, the concept of automotive engine parts polishing

Automotive engine parts polishing refers to the use of mechanical equipment on the surface of the engine parts grinding, polishing, in order to improve its surface finish, reduce the roughness, so as to improve the performance of the engine. Polishing not only improves the surface quality of the parts, but also improves their wear resistance, fatigue resistance and corrosion resistance, prolonging the service life of the engine.

Second, the importance of automobile engine parts polishing

1. improve engine performance: polished engine parts surface finish is higher, can reduce frictional resistance, reduce energy loss, thereby increasing engine power and torque. 2. extend engine life: polishing treatment can not only improve the surface quality of accessories, but also improve its wear resistance, fatigue resistance and corrosion resistance.

2. Extend engine life: polishing treatment can eliminate microscopic cracks and defects on the surface of the accessories, improve their fatigue resistance, reduce engine wear during operation, and extend the service life of the engine.

3. Reduce maintenance costs: Polishing can reduce the wear and tear of engine parts, reduce the maintenance frequency and maintenance costs.

4. Improve fuel economy: the surface of engine parts after polishing is smooth, the resistance of fuel in combustion is reduced, the fuel utilization rate is increased, so as to improve fuel economy.

5. Reduce emission pollution: polishing treatment can reduce the wear and tear of engine parts, reduce exhaust emissions, reduce environmental pollution.

Third, automobile engine parts polishing process

1. surface cleaning: put the engine parts into the cleaning solution, the use of ultrasonic or high-pressure water flow cleaning, remove surface oil, impurities, etc. 2. rough grinding: clean the engine parts into the cleaning solution, so as to reduce fuel economy.

2. rough grinding: put the cleaned parts into the rough grinding machine for grinding, remove the surface of the oxidation layer, rust, etc., to improve the surface finish.

3. fine grinding: put the roughly ground fittings into the fine grinding machine for grinding to further reduce the surface roughness and improve the finish.

4. Polishing: Put the fittings after fine grinding into the polishing machine for polishing, and utilize the polishing paste to grind the surface and improve the surface finish.

5. Cleaning: The polished fittings will be cleaned to remove the impurities such as polishing paste on the surface.

6. Inspection: Inspection of polished fittings to ensure that the surface finish, roughness and so on in line with the requirements.

Summarize:

Automotive engine parts polishing is important for improving engine performance, extending service life, reducing maintenance costs and reducing emission pollution. Through the polishing of engine parts, the overall level of the engine can be effectively improved to meet the needs of consumers for automotive power, economy and environmental protection. Therefore, the polishing process of automobile engine parts has a wide range of Application prospects in the field of automobile manufacturing.
