Abstract
The invention relates to a machine reamer, with a shaft-like base body (10) and a reaming head (12), projecting axially from the front face of the base body. According to the invention, the reaming head is in the form of a one-piece exchangeable cutting tip (12), which may be chucked into a tip seat (14) on the front face of the base body (10), in a coaxially self-centering manner, in order to maintain a high precision coaxialism, despite low material and construction requirements.
Claims33
A machine reamer comprising a shaft-like base body (10) and a reaming head projecting axially from the end face of the base body, characterized in that the reaming head is designed as a one-piece exchangeable cutting tip (12), which can be chucked in an auto-centering manner into an end face of a radially expandable tip seat (14) of the base body.
A reaming head for a machine reamer, characterized in that it is designed as a one-piece exchangeable cutting tip (12), which has a shoulder (24), which axially projects beyond a rearward facing planar surface (22), and which has at least three key surfaces (26), which are arranged spaced at equal angular distances from one another, and the planes of which supplement one another to form a regular, preferably equal-sided pyramid.
The reaming head for a machine reamer, characterized in that it is designed as a one-piece exchangeable cutting tip (12), which has a shoulder (24), which axially projects beyond a rearward facing planar surface (22), and which has an outer conical section and an outer polygon-sided section arranged between the outer conical section and the planar surface (22).
The reaming head for a machine reamer, characterized in that it is designed as a one-piece exchangeable cutting tip (12), which has a shoulder (24), which axially projects beyond a rearward facing planar surface (22), and which has a cylindrical fitting portion and an outer polygon-sided section arranged between the fitting portion and the planar surface (22).
