“…To counteract this phenomenon, the grinding process is carried out at lower speeds of wheel, with values from one third to half the speed used in conventional grinding. Lowering the grinding speed also favors the formation of residual stresses with smaller values in the workpiece surface, but in turn, causes a rapid blunting of abrasive grains, especially when grinding wheels with Al 2 O 3 abrasive grains are used, as what was described in the works [2][3][4][5][6][7][8][9].…”

In this article, we described a detailed analysis of the composition of elements remaining on the amorphous carbon-treated grinding wheel active surface (GWAS) after reciprocal internal cylindrical grinding of Titanium Grade 2 ® alloy. For this purpose, the scanning electron microscope (SEM) combined with energydispersive X-ray spectroscope (EDS) techniques were used. The SEM imaging and observation of selected fragments of active surface of 1-35 × 10 × 10-SG/ F46G10VTO grinding wheel was mainly carried out by use of two advanced microscopy systems: JSM-5500LV (JEOL Ltd., Tokyo, Japan) and Auriga ® (Carl Zeiss Microscopy GmbH, Jena, Germany). During EDS measurements, the Octane plus (EDAX, Inc., Mahwah, NJ, USA)-a high-accuracy silicon drift detector (SSI) was used. Conducted SEM-EDS analysis shows that applied impregnation method ensure the presence of impregnate in a grinding wheel body, also in subsequent work cycles of tool. Observed Ti cloggings on the GWAS appear solely on dulled vertices of active abrasive grains, which demonstrates the limited impact of the impregnate in the zone of direct contact between abrasive grains and machined workpiece surface. However, lack of extensive cloggings of the intergranular spaces indicating an effective removal of long ductile chips of Ti from grinding zone aided by the introduction of an amorphous carbon.

“…The grinding of BuRTi (Ti-25V-15Cr-2Al-0.2C wt%) has been assessed by several researchers using different abrasives and operating conditions [91,92,167,202]. Novovic et al [167] evaluated the performance of conventional and porous SiC wheels against a vitrified bonded diamond superabrasive wheel when creep feed grinding BuRTi.…”

“…This results from the low heat conductivity of such materials, which causes considerable temperature increase in the grinding zone. The high machining temperature also exerts negative influence on the operational resistance of the machined surface and fatigue properties of the workpiece [10][11][12][13].…”

The following article examines the influence of glass-crystalline bond in grinding wheels with grains made from microcrystalline aluminum oxide, and specifically its effect upon the values of selected operational indicators in the process of traverse internal cylindrical grinding of surfaces made from Inconel® alloy 600. The experimental test results obtained showed that changes in the bond phase composition, including its microstructure and volume share in the grinding wheel, has significant influence upon the workpiece surface roughness, grinding power, and other basic phenomena within the grinding zone. It was proven that the heat and physicalmechanical properties of the bonds have considerable influence on the mechanism of the grinding wheel components (abrasive grains and bond bridges) wear mechanisms. The phenomena occurring in the area of contact between the grinding wheel active surface and the workpiece surface requires on, among other things, the temperature at which the bond softens, initial bond hardness, the critical coefficient of grain strain intensity K Ic , the crystalline phases generated, and the volumetric share of the amorphous and crystalline phases in the bridges binding the abrasive grains.
