Pipe parts for aircraft (Cross hole)

Before
Tool

Rubber grindstone in the rotating tool

Problem

Finish quality varied from the skill of workers. It took around 40 minutes to deburr 16 holes (150 seconds/hole).

After
Tool

XEBEC Stone Flexible Shaft Type (CH-PM-6B)

Result

Insert the spherical grinding stone with the cross hole and contour the edge while pulling the tool lightly. Stable quality with shorter cycle time realized.
