摘要： The invention relates to a multi-edged machining tool for the post-machining or precision machining of bores. The tool has at least one cutting insert with a pre-determined nominal diameter measurement and with cutting edges that are distributed substantially uniformly around the periphery, in addition to a guide body assembly that is axially offset in relation to said edges. The guide body assembly can be an integral component of a substantially cylindrical guide body that consists of a solid carbide. In some embodiments, said guide body forms at least n helical guide ribs which are equidistant around the periphery and which have a nominal diameter substantially smaller than the nominal diameter measurement of the cutting insert by a value equating to double the dimension of the lubricant gap that is formed during the operation of the tool.

摘要： Described is a multi-blade cutting and drilling finishing tool for machining deep or stepped bores. The tool comprises at least a first blade set having a nominal diameter and blades distributed essentially uniformly over the circumference. In order to make it easier to guide the tool along the central axis, a guiding strip set in the form of very accurately positioned cutting inserts is located axially behind the first blade set with respect to the axial direction of the tool in which the tool advances forward to machine the deep or stepped bores. Each of the cutting inserts is aligned with one of the blades of the first blade set in a direction parallel to an axis of the tool, and each of the cutting inserts has a nominal diameter which is smaller than the nominal diameter of the first blade set by essentially twice the size of a lubrication gap forming between the guiding strip set and the deep or stepped bores when the tool is used.

摘要： Described is a multi-blade cutting and drilling finishing tool, in particular a reamer, for machining deep, especially stepped bores. Said tool comprises a set of blades having a predetermined nominal diameter and blades that are distributed in a substantially regular manner along the circumference. In order to make it easier to guide the tool along the central axis, a set of guiding strips in the form of very accurately placed and preferably cylindrically ground cutting inserts is located behind the set of blades in the advancing direction. Each of said cutting inserts is axially flush with the blades of the adjacent set of blades in the advancing direction of the tool and has a nominal diameter which is smaller than the nominal diameter of the set of blades substantially by twice the size of a lubrication gap forming when the tool is used.
