Introduction Today's manufacturing industry is facing the challenge of difficult-to-cut materials and difficult-to-cut materials in modern manufacturing industry is increasingly important, especially in the aerospace, automotive, tooling and other manufacturing fields, its outstanding material properties, such as high strength, heat resistance, wear resistance, corrosion resistance, etc. to improve product performance has made great economic benefits.
Faced with high hardness materials and the complexity of the molded parts, special processing to become a hot research issue processing field [1-3].
The materials of parts which maybe touch the electrolyte are stainless steel.

Introduction Polymer-derived microcellular ceramics are lightweight materials consisting of a microcellular structure.
Due to the combination of properties resulting from the polymer-derived ceramic material and the microcellular structure, these ceramics have a high potential for a number of industrial applications such as filters, insulators, gas sensors, catalytic carriers, absorbents, and lightweight structural materials [1-3].
The porosity of the microcellular ceramics was calculated from the bulk density of the microcellular ceramics and the theoretical density of the strut materials.
