Abstract
A throughaway milling cutter is disclosed: a cutter body rotatable about an axis; at least one recess formed at a front face of the cutter body and having a bottom wall and side walls; an inclined face formed at the bottom wall and inclined about the front face; a cartridge inserted in the recess movably along the inclination direction of the inclined face; a wiper cutting insert removably mounted to the cartridge and having a wiper cutting edge generally parallel to a plan perpendicular to the axis of the cutter body and a front flank face disposed adjacent to the wiper cutting edge; a wedge inserted between the side wall and the cartridge and capable of moving the cartridge along the inclination direction of the inclined face; and a means for clamping the cartridge to the recess.
Claims11
A throw-away milling cutter comprising:
- a cutter body rotatable about an axis, said cutter body having a rear face and a front face directed toward a workpiece;
- at least one recess formed at the front face of the cutter body, said recess having a bottom wall and side walls;
- an inclined face formed at the bottom wall, said inclined face being inclined toward a given direction with respect to the front face when the front face is directed upwardly;
- a cartridge inserted in the recess movably along said given direction of the inclined face;
- a wiper cutting insert removably mounted to the cartridge, said wiper cutting insert having a wiper cutting edge generally parallel to a plane perpendicular to the axis of the cutter body and a front flank face disposed adjacent to the wiper cutting edge;
- a wedge inserted between the side wall and the cartridge, said wedge being capable of moving the cartridge along said given direction of the inclined face;
- and
- a means for clamping the cartridge to the recess.
A throw-away milling cutter comprising:
- a cutter body rotatable about an axis, said cutter body having a rear face and a front face directed toward a workpiece;
- at least one recess formed at the front face of the cutter body, said recess having a bottom wall and side walls;
- an inclined face formed at the bottom wall, said inclined face being inclined toward a given direction with respect to the front face when the front face is directed upwardly;
- a cartridge inserted in the recess so as to be immovable;
- a wiper cutting insert removably attached to the cartridge, said wiper cutting insert having a wiper cutting edge generally parallel to a plane perpendicular to the axis of the cutter body and a front flank face disposed adjacent to the wiper cutting edge;
- a wedge inserted between the side wall and the cartridge, said wedge being capable of pushing the side face of the cartridge toward said given direction of the inclined face;
- said cartridge having a lower face contacting with said inclined face and an upper face mounting said wiper cutting insert, said lower and upper face being formed with at least one slit, respectively, so that the wiper cutting insert can be moved along said given direction of said inclined face when the wedge is pushed into said recess so as to elastically deform the portion adjacent to the slit.
