Abstract
A reaming tool has a shaft and a shaped head with at least one cutter. The shaped head is produced from a blank having a base body of a base material on its envelope surface with at least one rectilinear or helical groove-shaped recess running around it, into which high hardness cutting material is sintered.
Claims11
A reaming tool with a shaft (12) and a head (13) on which at least one cutter (21a) is provided,
- in which said head (13) is produced from a blank (17) that comprises a base body (18) of a base material with an envelope surface with at least one substantially rectilinear or helical groove-shaped recess (19) running around it, into which at least one high hardness cutting material (21) is sintered,
- wherein said at least one high hardness cutting material (21) comprises at least one guide (21b).
A process for production of a reaming tool (11) with a shaft (12) and a head (13) with at least one cutter (21a) and at least one guide (21b) comprising:
- at least positively connecting said shaft (12) to a blank (17) that has at least one groove-shaped recess (19) arranged on its envelope surface into which at least one high hardness cutting material (21) is sintered,
- producing at least one chip groove (22) in said blank (17) with a grinding wheel,
- moving said grinding wheel towards said recess (19) receiving said high hardness cutting material (21), and
- bringing said at least one hardness cutting material (21) to an intended dimension as said guide (21b).
A process for production of a reaming tool (11) with a shaft (12) and a head (13) with at least one cutter (21a) and at least one guide (21b) comprising:
- at least positively connecting said shaft (12) to a blank (17) that has at least one groove-shaped recess (19) arranged on its envelope surface into which at least one high hardness cutting material (21) is sintered,
- producing at least one chip groove (22) in said blank (17) with a grinding wheel,
- employing said at least one groove-shaped recess to produce at least one seating for a cutter (21a) in said blank (17) with a grinding wheel, and
- bringing said at least one cutter (21a) and said at least one guide in said blank (17) to an intended dimension.
A process for production of a reaming tool (11) with a shaft (12) and a blank (17) which has a base body (18) of base material, with at least one cutter (21a) and at least one guide strip (21b) comprising:
- at least positively connecting said shaft (12) to said blank (17) that has at least one groove-shaped recess (19) arranged on its envelope surface into which at least one high hardness cutting material (21) is provided,
- bringing the external diameter of said blank (17) to the dimension of the flight circle diameter of said at least one cutter (21a),
- producing at least one chip groove (22) in said blank (17) with a grinding wheel,
- moving said grinding wheel toward said recess receiving said high hardness cutting material (21),
- bringing said at least one cutter (21a) to said intended dimension, and
- producing said at least one guide strip in said blank (17), more material being removed at said base body (18) than at the outermost point of at least one guide strip (21b).
A reaming tool with a shaft (12) and a head (13) on which at least one cutter (21a) and at least one guide (21b) is provided,
- in which said head (13) is produced from a blank (17) that comprises a base body (18) of a base material with an envelope surface with at least one substantially rectilinear or helical groove-shaped recess (19) running around it, into which at least one high hardness cutting material (21) is sintered,
- in which said at least one high hardness cutting material (21) is arranged on said base body (18) and comprises guides (21b) and at least one cutter (21a) seated in said at least one recess.
A reaming tool with a shaft (12) and a head (13) on which at least one cutter (21a) is provided,
- in which said head (13) is produced from a blank (17) that comprises a base body (18) of a base material with an envelope surface with at least one substantially rectilinear or helical groove-shaped recess (19) running around it, into which at least one high hardness cutting material (21) is sintered,
- further comprising a chip groove (22) that, seen in the direction of rotation, is machined in said base body (18) preceding said at least one hardness cutting material (21), and said at least one high hardness cutting material (21) comprises at least one cutter (21a) and at least one guide (21b).
A reaming tool with a shaft (12) and a head (13) on which at least one cutter (21a) is provided,
- in which said head (13) is produced from a blank (17) that comprises a base body (18) of a base material with an envelope surface with at least one substantially rectilinear or helical groove-shaped recess (19) running around it, into which at least one high hardness cutting material (21) is sintered, further comprising guides formed from said high hardness cutting material, in which said groove-shaped recesses (19) correspond in number to the number of said cutters (21a) and said guides (21b).
