residual stress is a key factor that influences the reliability, precision, and life of final products. earlier studies have alluded to the fact that the grinding process is usually the source of a tensile residual stress on the part surface, while there exists a temperature
on the measurement of surface grinding temperature 289 consistent with findings reported by anerchik et al  where the workpiece speed was found to have the greatest influence on grinding temperature although cylindrical grinding conditions were used incited by: 65
abstract: as inner cooling grinding can break the closure of grinding area and solve practical engineering problems resulting from too high grinding temperature, it can be used to realize the grinding of difficult-to-machine materials, such as titanium alloy, in a general
the temperature of importance relative to surface integrity in grinding is the mean temperature of the work surface distributed over the arc of wheel-work contact (9w). the mean work temperature over the arc em v vs. x vs y b 's t k, pc a) 10 8 iq n 6 m > 4 v 2 0cited by: 3
the reduced number and controlled position of abrasives easily lead to reduced grinding forces and low grinding temperature. the grinding experiments of 42crmo4 (65 hrc) conducted by engineered wheels  indicated that, the maximum normal and tangential grinding forces decreased by 60% and 80% when the specific material removal rate was lower than 20 mm 3 /(mm*s) in comparison with cited by: 63
· pdf formation, grinding zone temperature and surface roughness in grinding aisi-1040 steel. the experimental results indicate significant reduction in cutting temperature on application of high-pressure coolant, which enables favorable chip formation and a better
in autogenous milling, temperature can significantly influence the grinding efficiency, particularly if the temperature falls below about 10 c. these efficiency changes can be reduced by preventing recycle water from becoming chilled, and by thawing frozen rock
one researcher found that when the workpiece surface temperature is below the boiling point of the fluid, a liquid phase will be present in the grinding arc. as the temperature of the surface increases, the liquid will undergo nucleate boiling, which can enhance
the grinding workpiece used in this study was a high-temperature nickel base alloy gh4169. the base oils of mql included castor oil, soybean oil, rapeseed oil, corn oil, peanut oil, palm oil, and sunflower oil. table 1 lists the chemical composition of gh4169, and table 2 cited by: 32
temperature of the grinding cement is reduced. c, strengthen the ventilation of the mill strengthening the ventilation of the mill can take away a part of the heat, but according to the calculation of the heat balance of the mill, the heat carried away by the
to explore the influence of the water vapor cooling conditions on grinding temperature field of titanium alloy tc4 material, ansys simulation and test methods are adopted in this paper. simulation and experimental studies show that: water vapor as coolant can
· pdf therefore, grinding under reduced temperature by means of water vapor was tested as a novel application. a pin mill with 5hp motor was used to grind chili with water mixing during milling in which water is considered as the coolant. the temperature of the 0
in order to predict the effect of the grinding temperature on the metallurgical state and hardness distribution in the workpiece subsurface after grinding, the reaction rate kinematics (equations (19) - (23)) were coupled with a thermal analysis, similar to the one
heat-producing grinding force and grinding power can he reduced by using sharp wheels, soft wheel grades, and frequent dressing (king and hahn, 1986). another method of controlling temperature is to employ cubic boron nitride (cbn) wheels.
10/2/2009· cs unitec’s tiger shark-plantex elastic discs feature a reduced grinding temperature and high material removal rates. they do not glaze with aluminum particles, so the discs are ideal for aluminum grinding applications, the company says.
