Bearing is an important part of mechanical equipment, its processing process includes roughing and finishing two links. This paper will introduce the technical points of bearing roughing and finishing, in order to improve the processing quality and efficiency of bearings.
Technical points of bearing roughing
Choose the right processing equipment: according to the material and size of the bearing, choose the right processing equipment, such as lathes, milling machines, drilling machines, etc.
Determine reasonable processing technology: according to the structure and technical requirements of the bearing, develop a reasonable processing technology, including processing sequence, cutting amount, coolant selection, etc.
Ensure processing accuracy: In the roughing process, it is necessary to ensure processing accuracy, especially the concentricity of the inner ring and the outer ring, to avoid difficulties in finishing.
Technical points of bearing finishing
Selection of high-precision processing equipment: finishing needs to select high-precision processing equipment, such as CNC grinding machines, super lapping machines, etc., to ensure processing accuracy and surface quality.
Determine the best processing technology: According to the accuracy and surface quality requirements of the bearing, determine the best processing technology, including grinding mode, grinding speed, feed rate, etc.
Strict control of the processing environment: finishing needs to be carried out in a constant temperature, constant humidity and dust-free environment to ensure processing quality and stability.
The surface quality of bearings has an important effect on their service performance and life. In the process of roughing and finishing, it is necessary to pay attention to the control of surface quality. Specific measures include: selecting the appropriate cutting fluid or grinding fluid to reduce thermal damage and wear on the workpiece surface; Reasonable control of feed rate and cutting speed, to avoid the surface of the workpiece chip and scale and other phenomena.
In the process of bearing processing, accurate measurement is an important means to ensure processing quality. In both roughing and finishing, multiple measurements are required to ensure that the dimensional accuracy and form and position tolerances of the workpiece meet the requirements. At the same time, the use of advanced measuring equipment and technology can improve the measurement efficiency and accuracy.
In short, the technical points of bearing roughing and finishing include selecting the appropriate processing equipment, determining the reasonable processing technology, ensuring the processing accuracy, selecting the high-precision processing equipment, determining the best processing technology, and strictly controlling the processing environment. At the same time, paying attention to surface quality control and accurate measurement is also an important means to improve the quality of bearing processing.
