ABSTRACT:
In a wood planing machine, a rotatable cutter seat is provided with at least one axially extending cutter receiving groove and two positioning disks at two axially opposing ends of the cutter receiving groove. A cutting element received in the cutter receiving groove has two axially opposing ends formed with axially projecting tongues. The positioning disks are notched to formed recessed tongue rest faces to seat the tongues when the cutting element is placed in the cutter receiving groove, thereby placing the cutting element in a proper orientation relative to the cutter seat without contacting the former with a groove bottom of the cutter receiving groove. The planing machine further includes an indicator which indicates a thickness that will be removed from a workpiece by the cutting element. The indicator includes a pointer and a workpiece contact element associated with the pointer. The contact element is a spring-loaded rod which has a rounded contact end, preferably with a semi-spherical shape, to contact the workpiece and is movable resiliently in a vertical direction, thereby eliminating the risk of being dragged by or stuck to the workpiece.
