摘要:
The invention concerns a milling tool for slot milling and a set of milling inserts of the milling tool. The milling tool comprises a tool body (2), a plurality of separated first seats (11; fig 6 ), which form root insert seats for root inserts (21) arranged one after the other along a first line, a plurality of separated flank insert seats (12,13; fig 6 ) that comprise a plurality of second seats (12) for flank inserts (22) arranged one after the other along a second line on a primary side of the root insert seats, and a plurality of third seats (13) for flank inserts (22) arranged one after the other along a third line on a secondary side (7) of the root insert seats. Each flank insert seat (12,13) comprises a bottom surface (16), an inner side surface (17), and an outer side surface (18). Each flank insert (22; Figs 17-21 ) comprises an under side (51), an opposite upper side (52), and a circumferential edge side (53) connecting the upper side (52) and the under side (51). A centre axis (A) extends through the upper side (52) and under side (51) of the flank insert (22). The edge side (53) of the flank insert (22) forms a rake face.

A clamping mechanism clamps a cutting insert in a tool body. The clamping mechanism has a clamping arm seated within a clamping arm pocket. The clamping arm includes a clamping protrusion extending rearwardly from a rear surface of the clamping arm. The cutting insert has a bore having an insert retaining surface and is seated within an insert pocket. Upon tightening the clamping arm into the tool body, the clamping protrusion presses against the insert retaining surface and the cutting insert is securely abutted within the insert pocket.

A high speed planer head. A threaded member (34) having a frustoconical portion wedges against a knife (104), to clamp a knife to a hub for rotating the knife about an axis of revolution. The knife has a front and back side, two cutting edges (136a, 136b) and mirror image symmetry about a mirror plane passing through the knife. To cut both a planar face and two opposed, radiused corners, the cutting edges include respective linear face-cutting portions disposed between two concave, arcuate corner-cutting portions.

The present invention relates to a tool for chip removing machining comprising a tool holder in order to releasably hold at least one cutting insert (13). The cutting insert is arranged to be fixable in an insert pocket of the tool holder by means of a locking screw (14). The locking screw has a head (15) and is in threaded engagement with the tool holder via a threaded joint (16; 17B), which is arranged to allow tilting of the locking screw in a working direction (R) of the tool when the locking screw is partly unscrewed, so that the cutting insert can be removed from the insert pocket. The head is arranged to clamp against a part of a front side (22), as seen in the working direction (R), of the cutting insert. The tool holder comprises at least one space (17D) at least partly arranged to receive the head when the screw is partly unscrewed.

The present invention relates to a router tool for edging the peripheral edge of eyeglass lenses. The tool comprises a longitudinally extending body rotatable on the axis thereof. A first blade extends axially and radially from the body, and has a first cutting portion for shaping an edge of a lens to a first configuration. A second blade is provided that is axially spaced from the first blade. The second blade extends axially and radially fromt he body, and has a second cutting portion for shaping an edge of a lens to a second configuration different than the first configuration. The present invention also relates to an edger having the disclosed router tool, and a method for shaping the edge of eyeglass lenses.

A milling tool (1) consists of a central body (2) in which at least one radial housing seat (3) is provided, at least a cutting knife (4) housed in the housing seat (3) and a locking assembly (5) also housed in the housing seat (3) and adapted to lock the knife (4). The milling tool comprises at least two lateral positioning pins (12) adapted to engage respective housings (13) formed in the cutting knife (4) and at least one base positioning pin adapted to engage a respective housing (17) formed in the base (4b) of the cutting knife (4). The two lateral positioning pins (12) extend or from a locking assembly (5) or from a supporting wall (6) of the housing seat (3), while the base positioning pin (16) extends from a bottom portion of the housing seat (3).
