1. Improvement of the main bearing part

The manufacturing accuracy of the main bearing and related parts directly affects the processing accuracy and overall effect, so it is necessary to start from the manufacturing accuracy of the main bearing and accessories to improve the manufacturing accuracy, and then strengthen the preload work of the rolling bearing to ensure that even if a certain error occurs during the rotation of the main bearing, it will not be reflected on the workpiece, thereby ensuring the accuracy of workpiece processing.

2. Correct selection and use of tools

Tools are important tools for workpiece processing. In order to improve the accuracy of workpiece processing, we must first work hard on tool selection, such as choosing tools made of new wear-resistant materials, and select the geometric parameters and usage of tools according to the specific conditions of processing. Then, we must perform correct pretreatment before using the tool to minimize the wear of the tool during specific use and ensure the accuracy of workpiece processing.

In addition, there is the correct selection of workpiece materials and the prediction of the heat that may be generated during the processing, and effective methods are used to prevent deformation caused by heat. Finally, in one clamping of the part, try to use the same tool to complete more machining surfaces to reduce the number of tool changes, simplify the machining route, and avoid errors caused by misalignment of the datum.
