Abstract
A tool for the precision machining of surfaces in workpieces comprising at least two cutter inserts in the periphery of the tool body and each having at least one defined cutting edge. The cutter inserts are of different materials at least in the region of the at least one cutting edge. Guide strips on the tool body periphery between the cutter inserts guide the tool body.
Claims39
A tool for precise machining of a surface of a bore in a work piece, the tool comprising:
- a main body with a periphery;
- a first and a second cutter insert supported at the periphery of the main body, the first and second inserts each being shaped to define at least a respective first cutting edge of the first cutter insert and a second cutting edge of the second cutter insert at the main body for machining the bore surface;
- the first and second cutter inserts being comprised of respective different first and second materials at least in the region of the at least one first cutting edge and second cutting edge;
- at least one guide strip provided in the main body for engaging the bore for guiding the positioning of the tool as the tool is rotated;
- the guide strip being behind the at least one of the first and second cutter inserts in the feed direction of the tool;
- the at least one guide strip, comprises a second strip at the periphery of the main body and located around the main body opposite the first cutter insert;
- and
- the at least one guide strip further comprises a third guide strip at the periphery of the main body and ahead of the first cutter insert by about 90° in the feed direction of the tool.
A tool for precise machining of a surface of a bore in a work piece, the tool comprising:
- a main body with a periphery;
- six cutter inserts arrayed around and supported at the periphery of the main body, the inserts each being shaped to define a respective cutting edge of the cutter insert at the main body for machining the bore surface;
- the cutter inserts being respectively comprised of respective different first and second materials at least in the region of the cutting edge;
- wherein the tool has the cutter inserts for defining six of the cutting edges.
