Nano-machining Experiment of Metal Materials Polishing with Ice Desk

Nano-level smooth surfaces are used more and more in high and new technology production, and requirement of them is higher and higher. Traditional polishing methods keep the surface roughness from further reduction because of the existing of abrasive materials. Nano-machining polishing on metal materials with ice desk is an originality innovation polishing method. Polishing desk is made of ice desk without abrasive materials, so nano-level surface roughness can be obtained. This paper makes some systematic researches on nano-machining polishing method on metal materials with ice desk. The paper proposes the experiment equipment that can realize the ice desk polishing on metal materials and the preparation of ice desk, work piece plate in detail. This paper also discussed the machining techniques of ice desk polishing and the disposal and measurement on work piece after machining. Metal materials polishing experiment are carried on with different kinds of water and pressure of press head. The water and pressure of press head which are best suitable for metal materials polishing experiment are obtained. Influential regularity of polishing metal materials is studied with different ice desk speed and work piece plate eccentricity. Based on theories of surface interface and metal fabric, from atomic and molecular level, microcosmic elimination mechanism of metal surface materials and variety of work piece surface roughness in ice desk polishing nano-machining on metal materials are discussed and analysed primitively
