Performance of SAE 52100 steel grinding using MQL technique with pure and diluted oil
(Springer, 2019-11-13)
Grinding is one of the highest dimensional accuracy machining processes in the industry. To obtain the smallest form and geometrical workpiece deviation, it is necessary to add cutting fluids as the aim of ensuring the ...
Performance of austempered ductile iron (ADI) grinding using diluted oil in MQL combined with wheel cleaning jet and different CBN grains friability
(Springer, 2020-03-01)
The large amount of heat generated during grinding is minimized using cutting fluid. However, they cause damage to human health and the environment and increase the cost of the process. Thus, reducing or replacing the use ...
Correlation of susceptibility of Cryptococcus neoformans to amphotericin B with clinical outcome
(American Society for Microbiology, 2011)
Testing of Cryptococcus neoformans for susceptibility to antifungal drugs by standard microtiter methods has not been shown to correlate with clinical outcomes. This report describes a modified quantitative broth macrodilution ...
Grinding behavior of austempered ductile iron: a study about the effect of pure and diluted MQL technique applying different friability wheels
(Springer, 2020-06-23)
Abrasion machining has stood out in the current industry due to constant improvements in the dimensional accuracy of a workpiece in its finishing process. Thus, it is necessary to use cutting fluid to cool and lubricate ...
Plasma and peritoneal fluid concentrations of ceftriaxone after intravenous and intraperitoneal administration in horses
(2018-04-01)
Intraperitoneal (IP) use of antimicrobial agents may lead to therapeutic effects with better clinical results than intravenous (IV) administration. The aim of this study was to compare plasma and peritoneal fluid concentrations ...
Aging, rejuvenation and thixotropy in yielding magnetorheological fluids
(Springer, 2013-05)
The yielding behavior of dilute magnetorheological (MR) fluids has been investigated using creep–recovery tests. At very low stress levels, MR fluids behave in the linear viscoelastic regime as demonstrated by the fact ...
Influência do fluido de corte e da concentração na retificação cilíndrica do aço 4340 e no desgaste do rebolo de CBN utilizando mínima quantidade de lubrificante
(Universidade Estadual Paulista (Unesp), 2019-07-05)
Atualmente, vários setores industriais têm buscado um desenvolvimento sustentável para os seus projetos. Dentre estes setores está a usinagem por abrasão, devido ao enrijecimento das leis ambientais e em virtude da necessidade ...
Geochemical characterization of the geothermal system at Villarrica volcano, southern Chile; part 1: impacts of lithology on the geothermal reservoir
(Elsevier, 2018-07)
Besides temperature, mineralogy, residence time and dilution are crucial for assessing water-rock interaction intensity. The geothermal system at the Villarrica-Quetrupillan-Lanin volcanic chain, Southern Chile, is located ...
Grinding performance of bearing steel using MQL under different dilutions and wheel cleaning for green manufacture
(Elsevier B.V., 2020-06-01)
Cutting fluids have a fundamental role in machining, especially in grinding, since they are responsible for lubrication and refrigeration of the cutting region. On the other hand, they may cause damage to the environment ...
