Aug 11, 2017 grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual.
Based on the above considerations an experiment is set up on a grinding machine of a real factory. the responses of an industrial roll grinding machine are measured by using pietzo-electric displacement sensors, rotation speed laser and accelerometers. the corresponding results should verify.
Dec 05, 2013 “the reason a traditional centerless machine is so hard to set up is that you never really know exactly how high up the part is positioned in the machine. with electronic height adjustment of the work rest blade, we can make the contact angles constant along the entire wear zone of the regulating wheel and the grinding.
Dec 15, 2001 before, minor grinding inaccuracies by vendors would result in inconsistencies in the finished gears. with the od/id grinder, there are fewer inaccuracies because critical features are ground in one setup on one machine. as a result, ground gears are more consistent part to part, and overall quality is.
