TECHNICAL FIELD

[0001] The utility model belongs to crystal growth furnace processing technical field, especially a kind of polishing tool for crystal growth furnace accessory machining. BACKGROUND

[0002] The volume of crystal growth furnace is huge, and the rack for supporting it is also extremely large. In the traditional processing method, the rack is usually formed by welding steel pipes and steel plates obtained by cutting. When the steel pipes are cut, many burrs will be generated on the cutting surface. In order to improve the processing accuracy, the burrs need to be polished and removed.

[0003] When polishing the cutting surface of the steel pipe, one end is usually fixed by a triangular chuck, and then the other end is polished by rotating the steel pipe. However, for some long steel pipes, if only the triangular chuck is used for fixation and support, the support force will be concentrated on one end during the rotation of the steel pipe, which may cause damage to the end of the steel pipe, and the stability of the rotation of the steel pipe cannot be guaranteed, thereby affecting the polishing effect.
