Corrugated roller superhard surface grinding and polishing machine tool and processing technology thereof

Abstract

The invention relates to a machine tool for grinding and polishing the superhard surface of a corrugated roller and its processing technology. The grinding machine tool of the present invention includes an indexing mechanism, a thimble, an electrode clamp assembly, a working fluid supply mechanism, a longitudinal feed screw, a bed, a spindle box, and a longitudinal feed motor, wherein the longitudinal feed screw and the longitudinal feed The output shaft of the motor is connected, and the electrode fixture assembly is installed on the longitudinal feed screw that can drive it to move longitudinally. The indexing spindle box is connected with the indexing mechanism, the workpiece and the electrodes in the electrode fixture assembly are respectively connected with the two poles of the power supply, and the working fluid supply mechanism sprays the working fluid between the workpiece and the electrodes of the electrode fixture assembly. The invention has simple structure and high efficiency. The processing technology of the present invention is based on electric machining or compound machining, which overcomes rigidity with softness, small force, and is flexible and changeable.

Description

Technical field: [0001] The invention relates to a machine tool for grinding and polishing the superhard surface of a corrugated roller and its processing technology, which belongs to the innovative technology of the corrugated roller grinding machine tool. Background technique: [0002] Corrugating roller is an expensive and easy-to-wear heart part in corrugating board machine. Its quality, especially the level of wear resistance, has a great impact on cardboard production cost and production efficiency. The surface treatment of the corrugated roller has changed from initial hardening heat treatment to hard chrome plating, and then to thermal spraying tungsten carbide, which greatly improves its wear resistance. Although the tungsten carbide roller exhibits excellent characteristics, due to the super strong and hard coating, the roughness of the original Ra3.0μm after thermal spraying should reach the Ra0.8μm required by the use, and ordinary grinding wheels cannot be groun...

AI Technical Summary

Problems solved by technology

Although the tungsten carbide roller exhibits excellent characteristics, due to the super strong and hard coating, the roughness of the original Ra3.0μm after thermal spraying should reach the Ra0.8μm required by the use, and ordinary grinding wheels cannot be ground. The diamond grinding wheel cannot be reshaped after the grinding wheel is worn out, so the existing process and equipment cannot be used in the manufacture of superhard corrugated rollers
