The grinder machine seems to act on area, which may cause annoying red notifications when grinding an object standing close by another object that requires a higher tier grinder, or lead to unintentional grinding a nearby object of grindable tier. I'd suggest to select objects to grind solely with hitscan at the aiming point, and apply grinding only to the aimed object.
