However, existing centerless grinder feeding devices have several shortcomings. Firstly, the feeding devices lack flexibility, making it difficult to quickly and accurately adjust to different bearing sizes and varying feed positions on the centerless grinder. This results in low equipment adaptability, requiring frequent changes or adjustments to the feeding device when machining bearings of various sizes, increasing production preparation time and costs.
