Hydraulic valve (Cross hole)

Before
Tool

Rubber wheel, carbide rotary bar on the rotating tool
Problem

The shape of edge was damaged and secondary burrs generated by deburring.
After
Tool

XEBEC Stone Flexible Shaft Type (CH-PM-5B)
Result

Allows the tool to contact with bending the shaft softly (displacement of bending = 0.5mm approximately).
Enables to remove the burrs only with keeping the shape of the edge.
Achieved good processing efficiency. The process used to cause tiredness for workers due to the long and narrow shape of workpiece.
