Analysis and Discussion of the Repair Technology of Surface Defects of Lathe Guide Rail
Abstract
As an important part of the lathe, the guide rails are subjected to huge forces, so there are often certain surface defects in the guide rails. The traditional manual polishing technology is time-consuming and labor-intensive, which limits the improvement of production efficiency. Aiming at this problem, this paper introduces and discusses the advanced defect repair technology of lathe guide rails, focusing on the selection and application of abrasive materials, grinding methods and grinding equipment. Through the technical analysis of abrasives and grinding tools, the defect repair process of guide rail surface is improved to reduce manual operation, improve precision and ensure the grinding quality.

1 Introduction
The guide rail of manual lathe is an important part to ensure the accuracy and efficiency of machine processing. According to the principle of rolling friction transmission of lathe, the surface of the guide rail should be processed and manufactured with high precision. The common surface defects of the guide rail include oxidation, scratches, rust and dirt. Manual grinding is usually used to repair the defects, which is inefficient and wasteful, and can not meet the modern high-efficiency production. Therefore, it is necessary to adopt advanced repair technology ofguide rail surface defect to improve the processing quality and reduce production costs.
2 Application and Selection of Abrasives
In general, the repair defects of guide rail surface can be divided into two types: machining defects and wear and tear. In view of the fact that the manual grinding of lathe guide rail has low efficiency, the same grinding effect can be achieved if the machining defects of the guide rail surface can be complemented and corrected in time. Abrasives with specific grinding particles and different grain sizes can be selected for different machining defects. The machining defects of coarse particles and impurities of the guide rail surface can be effectively improved by selecting abrasives with large grain size. For the repair of heavy wear and tear of lathe guide rail surface, fine abrasives with large number of small particles can be selected with higher grinding effect.
3 Grinding Method and Equipment
With the rapid development of manufacturing technology, the grinding technology of manual grinding of lathe guide rail has been gradually improved. In addition to using manual hand hammer grinding, surface grinding machine can also be used for grinding guide rail surface. The surface grinding machine adopts automatic mechanical grinding, and the grinding effect is better than that of manual grinding. Moreover, the grinding efficiency is greatly improved due to its high automation. Besides, the grinding effect of the surface grinding machine is more uniform than that of the manual grinding, which can achieve the effect of improving the performance of the guide rail and reducing the processing errors.
4 Comprehensive Consideration
Combined with the characteristics of guide rail surface defects, the selection of abrasives and grinding methods should be considered comprehensively when repairing certain defects. On the one hand, the abrasive material used for grinding should be selected for different machining defects according to the surface condition of the guide rail. On the other hand, grinding equipment should be selected for different grinding methods according to the machining condition and grinding effect. The selection of abrasives and grinding methods should be comprehensively considered in order to improve the grinding effect and ensure the quality of the guide rail.
Conclusion
In summary, the repair technology of guide rail surface defect has been introduced and discussed in this paper, focusing on the selection and application of abrasive materials, grinding methods and grinding equipment. Through the technical analysis of abrasives and grinding tools, the defect repair process of guide rail surface is improved to reduce manual operation, improve precision and ensure the grinding quality.
