SEM Studies in Textile Finishing Processes

Cyclodextrins in Textile Finishing

Surface finishing of unused rotary endodontic instruments: a SEM study.

During endodontic therapy, cleaning of root canals is performed using endodontic files and auxiliary chemical substances, and it is important that the endodontist be familiar with the instruments used in daily practice. This study evaluated, under scanning electron microscopy (SEM), the quality of the surface finishing of unused rotary endodontic instruments. Fifty sizes 20, 25 and 30 rotary fi...

Cutting Tools in Finishing Operations for CNC Rapid Manufacturing Processes: Experimental Studies

This paper reports an advanced approach in the application of CNC machining for rapid manufacturing processes (CNC-RM). The aim of this study is to improve the quality of machined parts by introducing different cutting tools during finishing operations. As the cutting is performed in different directions, the surfaces presented on part can be classified into several categories. Therefore, suita...

Corrective Abrasive Finishing Processes for Freeform Surface

Traditionally, abrasive finishing process focus on producing excellent surface finish on regular form shapes. Ever increasing demands in freeform features in aerospace, energy and medicine industry requires abrasive finishing technology not only provides excellent surface finish but also is capable to correct the errors on freeform surfaces. The paper presents current development of corrective ...

ECO-optimization of pre-treatment processes in metal finishing

8 Saving of bath chemicals and freshwater consumed within metal finishing systems and the reduction of wastewater produced can be important steps towards more sustainable processes. Furthermore, the application of regenerators is usually energy intensive. Accordingly, in an “eco–eco” (ECO) trade-off, importance should be given to both economic benefits as well as to several ecological measures....
