In ultrasonic machining with a diamond impregnated tool, the finishing techniques for polishing such surfaces of items from ceramics or ceramic composites demand equipment with the multi-axis movement of both the tool and the work.
Thus, finishing of ceramic turbine airfoils or blisks is considered to be rather complicated.
This equipment is designed for machining procedures of high efficiency when treating heavy-duty parts used in aerospace engineering.

These composites are composed of ceramic matrices combined with ceramic fibers based on alumina or silicon carbide.
Therefore bulk ceramics are mainly found as small highly charged parts in engineering.
Polymer derived ceramics are manufactured from silicon containing precursors which are converted into a ceramic.
All values were set into comparison to traditional engineering materials.

This International Standard deals with evaluation of bio-materials based on highly pure and stabilized bio-ceramics.
A ring from zirconia ceramics is loaded onto a flat plate from PEEK.
In the near future the full test will be completed, as required in the international standard - that means with five pairs of specimens from zirconia ceramics and PEEK.
