Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to a steel bar burr milling device. Background Art

[0002] Milling refers to the use of rotating multi-edged tools to cut workpieces. It is a highly efficient processing method. During operation, the tool rotates and the workpiece moves. The workpiece can also be fixed, but the rotating tool must still move. The machine tools used for milling include horizontal milling machines or vertical milling machines, as well as large gantry milling machines. These machine tools can be ordinary machine tools or CNC machine tools. The rotating milling cutter is used as the cutting tool for cutting. Milling is generally performed on a milling machine or a boring machine. It is suitable for processing planes, grooves, various forming surfaces, and special surfaces of molds.

[0003] In the process of rebar threading production, incomplete removal of burrs on the end face of the wire head or inadequate surface treatment may cause burrs on the surface of the rebar. The existing process is to manually grind the burrs on the end face of the rebar using an angle grinder, which is inefficient, has poor grinding quality, high labor intensity, and high safety risks. The quality and effect of manual grinding will have a certain impact on the threaded connection. Utility Model Content
