Inner diameter processing of long alumina pipe

This sample is a prototype of a alumina ceramics with an outer diameter of 26 mm, an inner diameter of 22 mm, and a length of 192 mm as a long alumina pipe.

We finished the inner diameter, but since the aspect ratio (L / D ratio) exceeds 8 processing becomes very difficult thing.

You can understand the longness of the sample from the size on the measuring table.

The measurement results of this sample are as follows.

Small diameter mold ULTRA PRECISION MACHINING

This sample is a prototype of a zirconia ceramics with an outer diameter of 7 mm, an inner diameter of 3 mm, and a length of 6 mm as a small diameter ceramics mold.

Required accuracy for this sample is very severe.
Roundness of 3 mm inside diameter, cylindricity within 0.0005, squareness to inner diameter and end face is within 0.0005.



The photograph shows a measurement scenery of roundness, cylindricity, squareness.
I think that you can understand the smallness of the sample from the size on the measuring table.

The measurement results of this sample are as follows.



We have cleared 0.0005 for both the roundness and the cylindricity.



Even though processing of the squareness is very difficult, we cleared 0.0005 here.
