    摘要： A milling device (1) for binding machines (2), for milling the back (D) of blocks (B) of sheets (S) to be bound, in which the machine (2) comprises a support plane (P) of the back (D) of the blocks (B) during their advancement. The device (1) comprises a disc-shaped plate (8) defining a main axis (V) and having a substantially circular outer peripheral edge (8A), an upper face (9) arranged facing the back (D) and a lower face (10) coupled to an electro-spindle (3), one or more cutting tools (13) which can be anchored in one or more centring points (A) of the upper face (9) to grind the back (D) by rotating the plate (8) and wherein each tool (13) comprises a cylindrical body (14) with a cutting edge (15) having a curved profile with centreline (M). There are provided for means (21) for anchoring the cylindrical body (14) to the plate (8) so that the centreline (M) is parallel to the tangent (T) on the outer peripheral edge (8A) in the centring point (A) of the tool (13) and so as to selectively direct the centreline (M) towards the one or the other rotation direction (R). A binding machine (2) which comprises the rotary milling tool (1) described above.

    摘要： A rotatable grinding tool (1) comprising a disc-like body (2) defining an intended direction of rotation (D), in which the grinding tool (1) is rotatable about a central axis (A) of the disc-like body (2), and a front side (3) intended to face a surface to be grinded, and a back side (4) opposite to the front side. The grinding tool (1) further comprises, on the front side (3) of the body (2), a plurality of teeth (5) each extending radially along said front side (3), wherein said teeth (5) being arranged spaced apart from each other. Particularly, the teeth (5) are formed integral with the body (2).

    摘要： A double-sided cutting insert (1) for use in a helical milling cutter with rectangular basic shape and four different working positions. A peripheral surface (10) extends around the cutting insert between two major faces (2, 3) and has two longer main side faces (11, 12) and two shorter main side faces (13, 14). A main cutting edge (31-34) is formed at an intersection between each longer main side face (11, 12) and each major face (2, 3). An inclined chip guiding surface (41-44) extends between each shorter main side face (13, 14) and each major face (2, 3). Each chip guiding surface intersects an abutment surface (5a, 5b) of the adjacent major face on both sides of a longitudinal centre plane of the cutting insert. The invention also relates to a helical milling cutter comprising a plurality of such cutting inserts.
