Description

Technical Field

[0001] The present application relates to the field of mechanical processing technology, and in particular to a dressing tool and mechanical equipment. Background Art

[0002] After the oil inlet and outlet holes on the cylinder are drilled, sharp flash will be left on the inner wall. When installing the piston, the sealing ring on the piston will be scratched by the flash. Therefore, the flash must be removed in advance and the chamfered square shell must be processed at the hole.

[0003] However, due to the limited space inside the cylinder, especially the cylinder with a smaller diameter, the angular electric drill cannot enter, and the ordinary electric drill with a grinding head can only remove flash but not chamfer. The inner wall surface may also be damaged due to the bouncing of the grinding head. Therefore, it can only be processed by manual scraping or filing, which has low processing efficiency and poor effect. Utility Model Content
