Utilization of teflon and aluminum oxide for wheel cleaning in Minimum Quantity...
Barros,Bianca Gomes; Silva,Tiago da; Canarim,Rubens Chinali; Aguiar,Paulo Roberto de; Bianchi,Eduardo CarlosResearches concerning cooling-lubrication optimization in grinding have been conducted to contribute to a more sustainable process. An alternative to flood coolant is minimum quantity lubrication (MQL), which spray oil droplets in a compressed air jet. However, problems related to wheel cleaning were reported, due to wheel loading by a mixture of chips and oil, resulting in worsening of surface quality. This wo...
Utilization of minimum quantity lubrication (MQL) with water in CBN grinding of...
Belentani,Rafael de Mello; Funes Júnior,Hamilton; Canarim,Rubens Chinali; Diniz,Anselmo Eduardo; Hassui,Amauri; Aguiar,Paulo RobertoThe use of cutting fluids is fundamental to machining processes, mainly when it comes to high heat generation, which is the case of grinding. Thus, lubrication and cooling provided by cutting fluids improve the final quality of the workpiece. However, cutting fluid usage provide some drawbacks concerning environmental, costs and health issues. Therefore, new methods for application and optimization of cutting f...
Evaluation of different methods of cooling-lubrication in cylindrical grinding ...
Simões,Rafael Plana; Bianchi,Eduardo Carlos; Oikawa,Marcos Hiroshi; Aguiar,Paulo Roberto de; Droppa Júnior,Roosevelt; Canarim,Rubens ChinaliThe current work presents a study of alternative methods of cooling-lubrication for the external plunge grinding of advanced ceramics using diamond wheels. These two alternative methods, which are intended to reduce cutting fluid expenses, are commonly referred to as the optimized cooling-lubrication method and minimal quantity of lubrication (MQL). The techniques were evaluated by process monitoring and by the...
