Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to a drainage tee pipe casting cutting device. Background Art

[0002] Cast pipes are a commonly used hardware material. They are widely used in engineering and building construction. After the pipe is cast, the surface of the cast pipe will usually have excess burrs due to the gap between the molds. These burrs will affect the subsequent processing and use of the pipe. The general way to deal with burrs is to manually grind them away using grinding equipment. During manual grinding, the scale of grinding can only be controlled by the worker's experience. Improper grinding control may result in over-deep grinding, affecting the quality of the pipe. In addition, due to the need to precisely control the grinding accuracy, a high degree of concentration is required during the grinding process, which makes manual operation very tiring.
