摘要： A drilling tool, in particular a reamer, for drilling out a workpiece core bore to a nominal diameter by means of a main blade formed on a drill body is disclosed. The main blade has a radially external cutting edge which extends along a drill-body longitudinal axis as far as a blade corner arranged at the drill tip, wherein during the drilling-out operation, the drilling tool is drivable into the workpiece core bore with a rotary movement and a feed movement. The drilling tool has at least one groove blade which is arranged so as to precede the blade corner of the main blade in the direction of rotation of the tool. During the drilling-out operation, the groove blade produces a groove in the inner wall of the core bore drilling, the blade corner of the main blade being guided in the groove with an at least reduced cutting load.

摘要： 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.

摘要： A method for reaming a hole in a metal substrate that minimizes the tendency of long and stringy metal chips to be formed that can surround the reamer with a nullsteel wool-likenull mesh or mass of material, as well as an improved reamer for carrying out this method. The reaming method involves longitudinally advancing the chamfered end of the reamer into the hole at an increased rate of at least about 5 mils (0.13 mm) per cutting edge as the hole is reamed during rotation of the reamer. For holes or bores having a length (L) that is at least about 3 times the cutting diameter (D) of the reamer, a preferred subsequent step is to momentarily reduce the rate of advance of the chamfered end into the hole to about 1 mil (0.025 mm) or less per cutting edge for from about 1 to about 5 rotations of the reamer. The improved reamer has a body, at least three flutes formed in the body, each flute terminating at a chamfered leading end and having a chamfer face proximate the chamfered end, the chamfer face having a chamfer angle of from about 20 to about 30null and having a leading edge of the margin that trails the rake face of the flute, i.e., a negative radial rake angle.
摘要翻译：一种用于铰链金属基底中的孔的方法，其最小化可以用“钢丝绒状”网状物或块状材料围绕铰刀的长而线状的金属屑的趋势，以及用于承载的改进的铰刀出这个方法。扩孔方法包括在铰刀旋转期间孔被延伸时，以每个切削刃至少约5密耳（0.13mm）的增加的速率纵向推进铰刀的倒角端到孔中。对于具有至少约3倍于铰刀的切割直径（D）的长度（L）的孔或孔，优选的后续步骤是将倒角端部进入孔的速度瞬间降低到约1密耳（0.025mm）或更少，每个切割边缘约1至约5旋转铰刀。改进的铰刀具有主体，在主体中形成至少三个凹槽，每个凹槽终止于倒角前端并且具有靠近倒角端的倒角面，倒角面具有约20至约30°的倒角角度，以及具有跟踪长槽耙面的边缘的前缘，即负径向前角。

摘要： A boring tool includes a clamping shaft and a boring body. Between the end face of the boring body and the clamping shaft, at least one main blade extends along a longitudinal axis of the boring body and includes a blade web with a rake face facing a groove-shaped chip space, and a free surface on the outer circumferential side, these converging at a cutting edge which runs along the boring body longitudinal axis and which removes material on an inner wall of a pre-bored workpiece core bore hole as a result of said boring tool being rotated. The main blade extending along the longitudinal axis of the boring body transitions at the end face, of the boring body into a groove blade that is aligned transversely to the longitudinal axis of the boring body. This groove blade allows the boring tool to be displaced, prior to removing the material by rotation, into the core bore hole in an axial lifting motion such that a groove is formed which extends along the longitudinal axis of the core bore hole, the main blade of the boring tool engaging in this groove.
