How does precision CNC grinding improve surface quality

Precision CNC grinding is a machining method that uses CNC technology to control the grinding tool to remove the surface of the workpiece. By precisely controlling the parameters of the movement path, pressure and speed of the grinding tool, high-precision machining of the workpiece surface can be achieved, thereby improving the surface quality.

The principle of precision CNC grinding to improve surface quality

1. Remove surface microscopic defects

The surface of the workpiece often has some microscopic defects in the processing process, such as scratches, pits, bumps and so on. Precision CNC grinding can remove these microscopic defects and make the surface more smooth and flat through the small cutting action of the grinding tool.

For example, in the manufacture of power transmission components, microscopic defects on the surface can affect the transmission accuracy and service life of the components. Through precision CNC grinding, the scratches and bumps on the surface can be removed, and the surface quality of the components can be improved, thus reducing the friction coefficient, improving the transmission efficiency, and extending the service life.

2. Reduce surface roughness

Surface roughness is one of the important indexes to measure surface quality. Precision CNC grinding can reduce the roughness of the workpiece surface to a minimum by controlling the movement track and pressure of the grinding tool.

For laboratory instruments and medical devices, the reduction of surface roughness can improve the accuracy and reliability of the instrument, reduce the possibility of bacterial growth, and ensure the safety of medical equipment.

3. Create an even surface texture

Precision CNC grinding can form a uniform surface texture on the surface of the workpiece according to different needs. This surface texture can improve the wear resistance, corrosion resistance and lubrication properties of the workpiece.

For example, in the manufacture of laboratory instruments, specific textures can be formed on the surface of the instrument through precision CNC grinding, improving the wear resistance and corrosion resistance of the instrument, so that it can maintain good performance in harsh experimental environments.

The key technology of precision CNC grinding

1. Numerical control system

The core of precision CNC grinding is the CNC system. The CNC system can precisely control the parameters of the grinding tool, such as the movement track, pressure and speed, so as to realize the high-precision machining of the workpiece surface.

The CNC system of iresearch Precision machinery adopts advanced control algorithms and high-precision sensors, which can realize real-time monitoring and adjustment of the grinding process to ensure the stability and reliability of the processing quality.

2. Grinding tools

The selection and design of grinding tools have an important influence on the effect of precision CNC grinding. Different workpiece materials and machining requirements require the selection of different types of grinding tools.

For example, for the workpiece material with higher hardness, it is necessary to choose a grinding tool with higher hardness; For medical devices with extremely high surface quality requirements, grinding tools with special shapes and materials need to be selected to ensure the processing effect.

3. Optimization of processing parameters

The machining parameters of precision CNC grinding include grinding pressure, grinding speed, feed rate and so on. Optimizing these parameters can improve machining efficiency and surface quality.

Through a large number of experiments and data analysis, iresearch precision machinery can optimize the processing parameters for different workpiece materials and processing requirements to achieve the best processing results.

As an advanced digital control machining type, precision CNC grinding has significant advantages in improving surface quality. By removing surface microscopic defects, reducing surface roughness and forming uniform surface texture and other principles, as well as key technologies such as numerical control systems, grinding tools and processing parameters optimization, precision CNC grinding can play an important role in the fields of power transmission components, laboratory instruments, medical equipment and so on.
