Abstract: A tool body (12) for a shell end mill (10) is described with at least one helical chip guiding groove (24) arranged at the circumference of the tool body (12) for chip dissipation and at least two receptacles (28) for indexable cutting inserts (26) arranged at the chip guiding groove (24). In this case, the receptacles (28) each comprise a base surface having a bore for receiving an indexable cutting insert fastening screw (34) and at least one first abutment surface adjacent to the base surface. The transition between the base surface and the first contact surface is a groove. In addition, a cutting tool is described with such a tool body, wherein a two-sided indexable cutting insert (26) is attached in each receptacle (28).

Abstract: A wedge clamp includes a top wall, a bottom wall, a front wall, a rear wall opposite the front wall, and a fluid port traversing from the front wall to the rear wall. The fluid port has a front opening and a rear opening to allow cooling fluid to pass therethrough. In one embodiment, the front opening is a rounded isosceles trapezoid in shape with a pair of parallel substantially planar side walls of different length and a pair of arcuate side walls connecting the pair of planar side walls. The rear opening has a greater surface area proximate the rear wall and a smaller surface area proximate the front opening, resulting in a funnel-shaped opening to cause an increase in velocity of the cooling fluid passing through the fluid port.
Abstract translation: 楔形夹具包括顶壁，底壁，前壁，与前壁相对的后壁，以及从前壁向后壁移动的流体端口。 流体端口具有前开口和后开口，以允许冷却流体通过。 在一个实施例中，前开口是具有不同长度的一对平行的大致平坦的侧壁的圆形等腰梯形，以及连接该对平面侧壁的一对弓形侧壁。 后开口具有靠近后壁的更大的表面积和靠近前开口的更小的表面积，导致漏斗形的开口，以引起通过流体端口的冷却流体的速度增加。

Abstract: The invention relates to a method for producing a blisk comprising a plurality of blade profiles and channels extending between the blade profiles using a bell-type countersink having a conical lateral surface, wherein the method comprises the steps providing a disk-shaped blank, and, to form the channels in the blank, plunging the bell-type countersink into the blank on a lateral surface of the blank and thereby moving it in a direction along a generating line of the bell-type countersink, wherein the displacement of the bell-type countersink is a 3-axial movement on a linear path and/or a 5-axial movement on a curved path. The invention also relates to a bell-type countersink.
