1) The workpiece center is not fixed. This is a unique feature of unintentional grinding.

(2) the workpiece itself positioning. The grinding surface of the workpiece is also the positioning surface, the original error and grinding error will be reflected as positioning error, thus affecting the workpiece grinding point near the shape error. According to this feature, some people think that in terms of roundness and waviness, inadvertent grinding without centering grinding high precision, it is not accurate. Because in a reasonable choice after the geometric layout, inadvertent grinding with active function.

(3) the movement of the workpiece by the wheel, guide wheel and pallet joint control. The stability of the workpiece movement depends not only on the machine movement chain but also on the actual conditions of the workpiece, guide wheel and pallet (eg workpiece shape, weight, guide wheel and pallet material, surface condition, machine form) and Grinding amount, geometric layout.

(4) Inadvertent grinding is easy to automate the production process.
