Hydraulic valve (Crosshole)

Effects after installation

Before
Tool

Rubber wheel, carbide rotary bur on rotating tool

Problem

Deburring broke shapes of edge and secondary burrs generated.

After
Tool

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

Effect

Allows the tool to contact, bending the shaft lightly (about 0.5mm displacement of bending).
Possible to remove only the burrs and keep the shape of the edge.
Achieved better processing efficiency; the process used to cause tiredness for workers due to the long and narrow shape of workpiece.
