The head has a plurality of locating surfaces spaced radially about the head which receive the finger joint cutter bits at a constant diameter. Each cutter bit is unitary and has a planar cutting face capable of being sharpened. The cutting face includes a plurality cutting teeth having linear fingering edges extending radially between adjacent base and tip edges. Each of the base edges are located at the same radius relative to the axis.

The device includes a cantilevered wall integrally connected to the tool body, that forms a portion of the pocket in the tool body that supports a side of the insert, and a wedge mechanism for elastically flexing the cantilevered wall to adjust the position of a cutting edge of the insert relative to the tool body. The wedge mechanism may take the form of a screw threadedly engaged to the tool body that has a conical head engaged against the cantilevered wall such that when the screw is turned, the conical wedge formed by the screw head flexes the cantilevered wall a small distance. The device advantageously allows fine adjustments to be made in the position of the cutting edge of an insert by the simple turning of a single screw.

Abstract: A milling tool (1) has at least one insert seat (14) which is adjustable in the axial direction. Provided for this purpose as an insert seat is a cartridge (47) which is received in a groove (41) but does not have a supporting face for the bottom face of the insert (25).

As a result, the insert seat (14) is formed by a combination of the plane face of the tool body (2) and bearing faces (51, 52) of the cartridge (47). This achieves a particularly small installation space (close tooth spacing) and rigid mounting of the insert (25).

Abstract: A milling cutter using a wedge to secure an insert within a pocket of the milling cutter wherein the wedge is tapered in both the axial direction and the radial direction. A screw urges the wedge within a tapered cavity to press the insert within the pocket along the axial wedge angle while rotation of the cutter creates centrifugal forces urging the wedge radially outward, thereby forcing the wedge against the radial wedge surface to further compress the insert within the pocket. The insert pocket may be extended to radially encompass the insert, thereby providing additional support against centrifugal forces for the insert.

Abstract: An improved knife clamping system for use in an apparatus for processing wood, such as a flaker, chipper or waferizer, that employs a rotary disc or ring, cutting knives, holding locations mounted on the disc or ring to receive the cutting knives, clamping members to engage and hold the cutting knives in position and fasteners to mount the clamping members to the holding locations. The improvement comprises providing a surface having an undulating profile to engage against the cutting knives.

Abstract: In a rotary cutter block each blade (14) is clamped in an inwardly divergent recess (12) by a wedge (16). The wedges (16) may be clamped simultaneously against their associated blades (14) by application of high pressure grease at any of one or more grease nipples (52, 54) which actuates by hydraulic plungers (22) in the bases of the wedge recesses (12). The angle of the wedges (16) is such as to provide a taper-lock between the wedges (16), the blades (14) and the recesses (12), which means that after depressurization the cutterblock can be stored or moved from one machine spindle to another without slackening of the wedges. The invention is of considerable advantage in reducing the amount of setting-up time involved in setting and grinding the blades of a rotary cutter head, since one pressurization is sufficient to tighten all the wedges simultaneously and to the same degree.

Abstract: An improved planing head for a wood planar is the subject of the present invention. A cylindrical planing head has a plurality of slots which receive the cutting blades and gib means for holding the blades in place during the planing operation.
