Inconel is a heat and pressure resisting alloy often used in jet engine component.
It is generally considered difficult-to-cut material, and indeed difficult to work on.
In machining this material, we realize cross hole drilling with cylindricity of 0.01mm, inside diameter tolerance of 0.005mm.

Material: Inconel718
Hole diameter: 12mm
Hole depth: 130mm
Roughness: Ra1.6

Processor: Rotary table Machining Center
Tool: Special tool

More the angle of the drilled cross hole is acute, harder to drill vertically to make true circle, having the drill reamer drawn toward the first drilled hole.
Our advance technique and tool can make a vertical drilling in true circle which technique others are yet to be able to realize.
