Abstract
Reamers, when operated with large amounts of material removed and at high reaming speeds, encounter difficulties when they ream in material in which permanent structural changes occur on the application of heat and subsequent rapid cooling. These difficulties are avoided in that the transition region between the main cutting edge and the minor cutting edge follows a constantly curved path at least one end region of which runs tangentially to at least the minor cutting edge.
Claims23
A cutter plate for a single cutter reamer, having a chip cutting surface comprising
- a main cutting edge,
- a minor cutting edge, and
- a transition region between said main and minor cutting edges, wherein said transition region in a plan view of said chip cutting surface follows a constantly curved path with an end region that runs tangentially at least with an extension of said minor cutting edge.
Process for the reaming of bores with a large amount of material removed and high cutting speeds in materials that can be hardened by heat comprising:
- employing a cutter plate of a single cutter reamer that has a main cutting edge and a minor cutting edge, and
- a transition region between said main cutting edge and said minor cutting edge that follows a constantly curved path with an end region that is tangential at least to an extension of said minor cutting edge.
