Centerless grinders are grinding equipment suitable for mass production. They can easily achieve high-power, high-speed and wide grinding wheel grinding. The grinding roundness can reach 0.0005-0.001mm, and the surface roughness can reach Ra0.1-0.025m. To achieve efficient grinding, it is very necessary to configure an automatic feeding device on the centerless grinder. It can realize the automatic operation of the equipment more safely and reliably, improve the utilization rate of the equipment, reduce the number of operators, and reduce the labor intensity of workers. The automatic feeding device of the centerless grinder can greatly shorten the production cycle. The products ground by the centerless grinder are divided, arranged, counted, etc., and are grabbed by the manipulator fixture.
