The application provides a wire feeding device and a busbar welding machine. The wire feeding device comprises a wire pressing wheel assembly, a wire feeding wheel assembly, a connecting seat and a wire guide tube. The wire pressing wheel assembly is used for pressing a wire harness. The wire feeding wheel assembly is arranged on one side of the wire pressing wheel assembly. The connecting seat is connected to the side of the wire feeding wheel assembly away from the wire pressing wheel assembly. The wire guide tube is connected to the connecting seat and forms a wire guide cavity. The wire feeding wheel assembly is used for moving the wire harness into the wire guide cavity. The wire feeding device of the application can automatically move the wire harness and accurately control the wire feeding length. The wire harness is guided by the wire guide tube, so that the wire harness can be accurately delivered to a specified position. The wire harness processing effect is not affected by unstable and inaccurate movement of the wire harness, thereby ensuring the pretreatment effect of the wire harness.

The application discloses a process method of sand blasting before machining for high-quality and high-efficiency machining of hard and brittle materials, and belongs to the technical field of precision machining of hard and brittle materials. In view of the problems of easy edge collapse, cracks and low machining efficiency of hard and brittle materials in cutting, sand blasting treatment is performed on the surface to be machined of a workpiece before mechanical cutting machining, a uniform micro-crack damage layer is formed in a controllable manner on the material surface layer by using the impact of high-speed abrasive particles, and the bonding strength of the surface layer is weakened; subsequent cutting machining is then performed, so that the material is mainly removed in brittleness and secondarily removed in ductility, the cutting force and tool wear are significantly reduced, defects such as edge collapse and cracks are inhibited, and the machining surface quality and machining efficiency are improved. The process is simple and has strong adaptability, and can be widely applied to the precision and high-efficiency cutting machining scenes of various hard and brittle materials such as ceramics, monocrystalline silicon and sapphire.
