Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, and in particular to a flexible polishing device with a conductive nozzle. Background Technology

[0002] The contact tip is a key component in welding equipment, typically mounted at the front of the welding torch, serving as a guide and conductive channel for the welding wire. It is in direct contact with the welding wire and plays a crucial role in transmitting welding current during the welding process. During the machining of the contact tip, its surface is relatively rough and contains burrs, requiring the use of a grinding device to remove them.

[0003] In existing technologies, grinding devices may lack sufficient design flexibility, making it difficult to be compatible with various types of conductive tips. This means that different grinding devices or complex equipment adjustments may be required for different types of conductive tips, increasing equipment costs and management complexity.
