Drag marks are only caused by one of the problems discussed above,
i.e. misalignment, part movement or deflection. Customers sometimes
ask if they can correct drag mark problems by chamfering blades.
Chamfering blades will probably increase the optimum cutting
action of the blades but it will not correct for drag marks. Only
correction of the misalignment, part movement or deflection problem
will solve the drag mark problem.
