施加给工件的外力小
这种工艺可以对工件进行左右两边同时加工，相对于单个CBN砂轮可以节省一半的时间，同时优化工件质量，例如表面精度、同心度和圆度。
此结构不仅适用于所有重要部件，而且相于两轴卧式磨床更有优势：进向力可以被抵消。
优势
In conventional grinding it is the normal forces that have the greatest impact on the workpiece, and they are usually three or four times that of the tangential forces. With simultaneous grinding the normal forces are cancelled out by the two grinding wheels being arranged opposite each other. As the wheels also run in opposing directions, the torque created by the tangential forces is also cancelled out. However, in the case of very slender or not very stable shafts being ground the conventional way, the resulting tangential forces can still cause deformation.
For the machining of these shafts the synchronous support grinding process developed by EMAG is ideal, as it includes the use of a steady that is positioned against the seat, and which advances in synch with the grinding wheels until the desired shaft dimension is ground – a design that also absorbs all the tangential forces.
