Problem statement: Single Point Diamond Turning (SPDT) is highly deterministic and versatile in producing various forms of precise optics. A typical example is the production of large offaxis aspheric mirrors and various infrared mirrors and mandrels. However, the fine periodical turning marks left in the surface critically limit its performance and they are difficult to be avoided for traditio...

Abstract A magnetic abrasive finishing is a non-traditional technology utilizes flexible brush comprises of particles under the influence field to perform nano-finishing. The material removal ( MR ) and percentage change in surface roughness (%∆ R are responses governing efficiency process. But, high during operation leads loss form/shape finished surface. compromise has be made considering two...

Magnetic abrasive finishing (MAF) is a fast, high efficiency and high-precision polishing method on the surface machining of metals. Furthermore, MAF also can be utilized to polish stainless tubes in industrial applications; however, are often non-magnetic material that makes it difficult for magnetic field line penetrate into tubes, thus reducing forces inner polishing. That why not easy finis...

In this article, we present a numerical model of magnetic abrasive finishing station, which was analyzed using the finite element method (FEM). The obtained results were compared with real values measured on an experimental station our own design. prepared had option adjusting flux density inside machining gap, width could be changed from 10 to 30 mm. maximum value air gap 0.8 T. distribution i...
