“…A grinded foil (1) is mounted on the body of the instrument (6). One end of the foil (1) is mounted in a permanent holder (5), while the other end is mounted in a sliding holder (2). The sliding holder is connected by a connecting link (3) with a clamping mechanism (4) which compensates for the elongation of the foil during grinding and enables formation of a constant tension force in the metal foil.…”

“…The direction of rotation of the grinding wheel (8) is opposite to that of the instrument's body (6) where the foil (1) is mounted. The body (6) must be attached between the grinding centers such that the cutting force acting on (1) is oriented from the permanent holder (5) toward the sliding holder (2). As a result, the tension force of the foil is maintained constant during grinding.…”

“…EP-type additives react chemically with the metal being machined, forming on the surfaces of the machined object and the machin-ing tool thin layers of products acting as a permanent lubricating film. The efficiency of the action of EP-type additives can be assessed using a fourball testing machine [2,6].…”

A method is presented for the study of surface-active properties of a fluids, in burnishing and shot peening processes used, which consists in comparing mean plastic strains of thin metal foil subjected to tensile tests in the examined fluid and in air. As a surface-active additive to the fluid (mineral oil), methyl polymethacrylate solution was used. It was found that the surfactant activity coefficient depended on the type of examined fluid as well as on the thickness of the foil being stretched. Results of analyses of the surface-active properties of a fluid can be compared only when metal foils of equal thickness made from one specific material are used. It can be supposed that the introduction of methyl polymethacrylate solution as an additive to the metalworking fluid will have a beneficial effect on the course and the results of burnishing and shot peening of metals.

“…In the cutting fluids formulation, the modified vegetable oils are more than just a biocompatible alternative, due to their biodegradable characteristics, they also have low levels of corrosivity, excellent lubricity, low volatility and good viscosity and temperature characteristics 10 . In addition, they show excellent physical and chemical adsorption properties due to their chemical structure, promoting the formation of a more resistant lubricating films…”

The Lubricity Analysis of Cutting Fluid Emulsions

et al. 2017

The new generation of cutting fluids should have some characteristics, such as low toxicity and biodegradability. A bio-cutting fluid emulsion are an excellent option because they present those properties, as well as good mechanical performance. The present study aims to investigate the lubricity of O/W emulsions (cutting fluid emulsion), varying the concentration of anionic surfactant (1%, 2.5% and 5%) and epoxidized oil (5%, 10%, 15%, 20% e 25%). A sunflower oil was chemically modified by epoxidation reaction, then its viscosity, iodine and oxirane index, density, and acidity were characterized. The performances of the emulsions were evaluated using a tribometer HFRR (High Frequency Reciprocating Rig), under hydrodynamic lubrication conditions. The ball wear scars were analyzed using an optical microscopy. The results showed that a low concentration of surfactant promote friction and wear reduction. Based on the tribological performance, the emulsions with 5% and 10% of epoxidized oil are more suitable.
