Abstract
A combination tool including a base body with several reaming blades each having a chamfer and a guide surface, arranged around the circumference of the base body, for reaming a cylinder bore. The combination tool also has at least one grooving blade arranged axially offset from the reaming blades and which may be extended radially relative to the base body. The combination tool is provided with two guide strips, arranged in the base body, at an angle to each other, between two reaming blades which are adjacent in the circumferential direction and displaced axially relative to the above in the direction of the grooving blade.

A combination tool for use in machine tools for the machining of workpieces comprising a base body with several reaming blades for reaming a cylindrical bore, which reaming blades are distributively arranged over the circumference of the base body, and have a chamfer and a guide surface, the combination tool further comprising at least one grooving blade arranged axially displaced on the base body with respect to the reaming blades, and controllable radially with respect to the base body, wherein two guide strips are arranged at an angular distance from one another between two circumferentially mutually adjacent reaming blades in the base body, and are displaced axially with respect to the reaming blades in direction of the grooving blade, the guide strips have the same flight-circle radius as the reaming blades, and provide support during a grooving operation at an angular distance on opposite sides of a cuttingforce resultant of the at least one grooving blade within a bore.
A combination tool for use in machine tools for the machining of workpieces comprising a base body with several reaming blades for reaming a cylindrical bore, which said reaming blades are distributively arranged over a circumference of the base body, and have a chamfer and a guide surface, the combination tool further comprising at least one grooving blade arranged axially displaced with respect to the reaming blades, and capable of being radially movably controlled with respect to the base body, and at least two guide strips for providing support during a grooving operation by the at least one grooving blade, wherein adjacent reaming blades have in part varying angular distances and an axial displacement adjusted thereto.
A combination tool for machining of workpieces comprising:
- a base body having a circumference thereabout;
- several reaming blades for reaming a cylindrical bore located at angular distances from one another and spaced radially about the circumference of the base body;
- at least one grooving blade arranged axially displaced with respect to the reaming blades;
- and
- at least two guide strips arranged at an angular distance from one another and spaced radially about the circumference of the base body, the two guide strips being displaced axially with respect to the reaming blades in the direction of the at least one groove blade and located between first and second circumferentially mutually adjacent ones of the reaming blades, the guide strips having the same flight-circle radius as the reaming blades and providing support during a grooving operation by the at least one grooving blade within a bore in a workpiece.
