The important role of double disc grinding machines in bearing manufacturing
In the field of bearing manufacturing, double disc grinding machine plays a vital role. It provides a strong guarantee for the high quality production of bearings with its unique processing advantages.
First, the precision requirements of bearing manufacturing
As a key component in the mechanical transmission system, bearings have extremely high precision requirements. Whether it is dimensional accuracy, shape accuracy or surface roughness, it directly affects the performance and service life of the bearing. For example, the diameter tolerance of the inner and outer rings of the bearing is usually at the micron level, cylindricity, roundness and other shape errors must also be controlled within a very small range. At the same time, the working surface of the bearing needs to have a very high surface finish, in order to reduce friction and wear, and improve the operating efficiency and reliability.
Second, the working principle and characteristics of double disc grinding machine
Double disc grinding machine is a kind of machine tool that can grind two end faces of the workpiece at the same time. It usually adopts two grinding wheels to grind the two end faces of the workpiece respectively. When working, the workpiece is fixed on the table by the fixture, and the workpiece is driven by the feeding system to move between the two grinding wheels to achieve the grinding process.
The double disc grinding machine has the following characteristics:
High efficiency: able to process two end faces at the same time, which greatly improves the productivity. Compared with the traditional single endface grinding, the processing time can be shortened by more than half.
High precision: the use of advanced CNC system and high-precision feeding mechanism can ensure the machining precision at the micron level. Meanwhile, the sharpness and precision of the grinding wheel can be maintained in real time by the automatic dressing and compensation function of the grinding wheel.
Good stability: The machine tool has a sturdy structure and high precision in the coordination of all components, which can maintain stable performance during a long time of machining. Even in the case of high-speed grinding, the machining accuracy and surface quality can be guaranteed.
Strong adaptability: it can process workpieces of various shapes and sizes, including round, square, rectangle, etc. Meanwhile, different grinding wheels and grinding parameters can be selected according to different processing requirements.
Third, the specific application of double endface grinding machine in bearing manufacturing
Bearing inner and outer ring endface grinding
The inner and outer rings of bearings are the key components of bearings, and the accuracy of their end faces directly affects the assembly accuracy and running performance of bearings. Double disc grinding machine can grind the endface of inner and outer rings of bearings with high precision to ensure that the flatness, parallelism and surface roughness of the endface meet the requirements. By precisely controlling the grinding parameters, it is possible to process the inner and outer rings of bearings of different sizes and precision requirements.
Cage endface grinding
The cage plays the role of isolating the rolling body and guiding the movement of the rolling body in the bearing. The end face accuracy of the cage also has an important influence on the performance of the bearing. It can grind the endface of the cage, improve the dimensional accuracy and surface quality of the cage, and ensure the matching accuracy between the cage and the rolling body.
Roller endface grinding
Roller is the rolling body in the bearing, and the precision of its end face directly affects the bearing capacity and running precision. The machine can grind the endface of the roller with high precision to ensure that the endface flatness and round runout of the roller are within a very small range. At the same time, through the batch processing of the roller, it can improve the production efficiency and reduce the production cost.
Fourth, the double disc grinding machine on the bearing manufacturing quality improvement
Improvement of machining accuracy
The high-precision machining capability of the equipment can ensure the dimensional accuracy and shape accuracy of each component of the bearing, and improve the assembly accuracy and running performance of the bearing. It reduces the early failure of bearings caused by machining errors and prolongs the service life of bearings.
Improvement of surface quality
High-quality grinding of the working surface of the bearing can be achieved through precise control of the grinding parameters and selection of grinding wheels. This improves surface finish, reduces friction and wear, lowers running noise, and improves the reliability and stability of the bearing.
Increased productivity
The high-efficiency machining characteristics of the double disc grinding machine can greatly shorten the production cycle of the bearings. At the same time, through the automated loading and unloading system and CNC programming, unmanned production can be achieved, reducing labour costs and improving production efficiency.
Fifth, the summary
Double disc grinding machine has an irreplaceable and important role in bearing manufacturing. It provides a strong guarantee for the high-quality production of bearings with its high efficiency, high precision, good stability and adaptability. With the continuous development and progress of bearing manufacturing technology, the application of the machine will be more and more extensive, and make greater contribution to promoting the development of the bearing industry.
