Problems solved by technology

The grinding wheel dresser and guide wheel dresser configured on the centerless grinder are mainly diamond pens that can be adjusted independently. However, since each component moves independently, the motion error introduced is relatively large, which makes the dressing accuracy low and the dressing process takes less time. It is difficult to meet the high-efficiency and high-precision processing requirements of cylindrical rollers
[0005] Therefore, it is urgent to develop a new ceramic cylindrical roller centerless grinding technology to effectively solve the problem of low dressing accuracy of grinding wheels and guide wheels in centerless grinding, which affects the processing accuracy, and the problem of time-consuming dressing process affecting processing efficiency.

Abstract

The invention discloses a ceramic cylindrical roller penetrating type centerless grinding machining method. The method is characterized in that a trimming wheel is arranged at the side portion of a guiding wheel, and tool electrodes are arranged on the side portions of a grinding wheel and the trimming wheel. According to the method, during machining, metal bonding agents on the surfaces of the grinding wheel and the trimming wheel generate anodic dissolution through an electrolytic mode so as to realize online synchronous trimming, so that the grinding wheel and the trimming wheel perform trimming on the same reference, and the high trimming precision on a mechanical structure is guaranteed; in addition, online electrolytic trimming can avoid grinding wheel surface passivation and blockage so that the grinding wheel can maintain good grinding performance for a long time; and meanwhile, the guiding wheel performs online trimming, so that the contact friction coefficient of the guidingwheel and a cylindrical roller is stable, the cylindrical roller machining precision is high, the surface quality of the cylindrical roller is guaranteed, and the machining efficiency is high. The invention further provides a ceramic cylindrical roller penetrating type centerless grinding machining device correspondingly. According to the device, high-efficiency and high-precision grinding machining of the ceramic cylindrical roller is realized.

Description

technical field [0001] The invention relates to a high-efficiency and high-precision centerless grinding method and device for ceramic cylindrical rollers, belonging to the technical field of precision and ultra-precision machining. Background technique [0002] Cylindrical rollers, as a rolling element, have the ability to withstand high loads due to their linear contact with the raceway, and are especially suitable for mechanical equipment with large loads and high-speed rotation, such as high-speed machine tool spindles, wind power generators, rail locomotives and other fields. With the development of high-speed and high-precision mechanical equipment spindles, ceramic cylindrical rollers have excellent comprehensive properties such as high hardness, high rigidity, high temperature resistance, and corrosion resistance, and are considered to be the best materials for manufacturing bearing rolling elements. [0003] Through-type centerless grinding technology is the main w...
