Abstract
A machining tool for the fine machining of internal surfaces, with a blade carrier and cutting inserts preferably attached releasably thereto. An adjusting device for the precision adjustment of the cutting edge is provided. The blade carrier has at least one slit located closer to the longitudinal axis of the machining tool than is the cutting insert, thus creating a blade carrier segment which can be essentially radially adjusted and which carries the cutting insert and which is connected in one piece with the remaining blade carrier. The degree of freedom of the blade carrier segment permitted by the slit can be stabilized via adjusting device.
Claims19
A rotary tool, comprising:
- a blade carrier;
- at least one slit extending in said blade carrier in a straight line in a plane which is substantially parallel to a longitudinal axis of the rotary tool, thereby creating a blade carrier segment connected to a remainder of said blade carrier by a material joint;
- a cutting insert mounted to said blade carrier segment such that said at least one slit is located closer to the longitudinal axis of the rotary tool than is the at least one cutting insert;
- and
- an adjusting device comprising means for creating a first force vector and a second force vector which have opposing vector directions, the first force vector and the second force vector being substantially perpendicular to the at least one slit, said adjusting device partially located in both of said blade carrier and said blade carrier segment for radially positioning the cutting insert.

A rotary tool, comprising:
- a blade carrier;
- two slits extending in said blade carrier in a straight line in a plane which is substantially parallel to a longitudinal axis of the rotary tool, thereby creating a blade carrier segment connected in one piece with a remainder of said blade carrier by a material bridge remaining between the two slits;
- a cutting insert mounted to said blade carrier segment such that said at least one slit is located closer to the longitudinal axis of the rotary tool than is the at least one cutting insert;
- and
- an adjusting device comprising means for creating a first force vector and a second force vector which have opposing vector directions acting through the at least one slit so as to stabilize and position said blade carrier segment to said blade carrier, the first force vector and the second force vector being substantially perpendicular to the at least one slit, said adjusting device partially located in both of said blade carrier and said blade carrier segment, said adjusting device having at least an adjusting element and a fixing element.
