摘要： The holder has a recess at its cutting end, with a longitudinal slot extending rearwardly from the back of the recess to provide jaws, with a vertical bolt through the jaws to clamp the jaws against upper and lower end edges of a cutting insert received in said recess. Upper and lower opposed parallel, longitudinal edges of the recess are concavely shaped transversely, to slidably receive complementary transversely shaped parallel, longitudinal surfaces of the insert to prevent side movements or tilt of the insert in the tool holder. Once the insert is clamped in the tool holder, it will remain tightly clamped thereon even with substantial loads on the cutter insert and considerable vibrations. A high degree of accuracy will repeatedly occur in location of the cutter element in the tool holder. Additional advantage in clamping accuracy is provided if the cutting insert and matching nesting recess are made with concave-convex complementary sliding surfaces at the back ends of the recess and insert, as well as at the top and bottom.
摘要翻译：保持器在其切割端处具有凹部，其纵向槽从凹部的后部向后延伸以提供夹爪，垂直螺栓穿过夹爪，以将钳口夹紧到接收在所述凹槽中的切削刀片的上端和下端边缘休息。凹槽的上下相对的平行的纵向边缘是横向成凹形的，以可滑动地接收插入件的互补的横向平行的纵向表面，以防止插入件在工具架中的侧面移动或倾斜。一旦插入件被夹紧在工具夹具中，即使在刀片插入件上有相当大的载荷并且具有相当大的振动，它也将保持紧紧地夹在其上。刀具元件在工具架中的位置将会重复地发生高精度。如果切削刀片和匹配的嵌套凹槽在凹槽和插入件的后端以及在顶部和底部由凹凸互补的滑动表面制成，则提供夹紧精度的另外的优点。

摘要： A tool body having a longitudinal body axis has a central body recess recessed in a rear body surface thereof. The recess includes an inner recess surface, and a body recess peripheral surface extending between the inner recess surface and the rear body surface. An integral central pin extends rearwardly from the inner recess surface, and having an integral pin length measured along the longitudinal body axis from the inner recess surface to a rear pin surface thereof. In a circumferential direction about the longitudinal body axis, the body recess peripheral surface alternatingly increases and decreases in distance from the longitudinal body axis, thereby forming a plurality of angularly spaced apart longitudinal axis crests. A tool holder has a protrusion with complementary surfaces to engage the tool body. A fastening member, such as a lock nut, secures the tool body to the tool holder to form a cutting tool.

摘要： A cutting tool includes a replaceable cutting head including a forward cutting portion and a rearward mounting portion and a head through hole extending therethrough. The mounting portion includes a male coupling member. The male coupling member includes a conically shaped head abutment surface. The cutting tool includes a female coupling member including a conically shaped forward holder abutment surface and an internal thread. The cutting tool includes a fastening member having an external thread. When the cutting tool is in a locked position, the male coupling member is removably retained in the female coupling member by the fastening member located in the head through hole, the fastening member external thread and the holder internal thread being threadingly engaged with each other. The head abutment surface abuts the forward holder abutment surface thereby forming a Morse taper coupling between the male and female coupling members.

摘要： A tool coupling extends along a longitudinal axis and has a first component, a second component, and a clamp for fastening the first component to the second component. The first component has a male clamping portion, the second component has a female clamping portion, and the clamp is located in an inner cavity of the second component. The male clamping portion has a first abutment region located axially rearward of a first plane perpendicular to the longitudinal axis, the inner cavity has a second abutment region located axially forward of the first plane, and the first and second abutment regions face towards the first plane. In a fastened state, a clamp first engagement region of the clamp makes clamping contact with the male clamping portion's first abutment region, and a clamp second engagement region of the clamp makes clamping contact with the inner cavity's second abutment region.

摘要： A tool holder has a holder body, a first clamping member, and a first fastening member. The holder body includes a fixation portion and a mounting portion located rearward of the fixation portion. The fixation portion has a front fixation surface facing in a forward direction, a cylindrical fixation bore opening out to the front fixation surface and extending rearwardly therefrom, and a longitudinally extending primary slot connecting the fixation bore to a fixation envelope surface. The first clamping member occupies a first clamping bore and traverses the primary slot. The first fastening member occupies a first fastening bore which intersects the first clamping bore and opens out to the front fixation surface. The fixation bore has a fixation bore first primary diameter which decreases and increases when the first fastening member is rotated in first fastening and first unfastening directions about the first fastening member axis, respectively.

摘要： A cutting insert adaptor for an insert pocket can include one or more pairs of opposing insert abutment surfaces and pocket abutment surfaces which converge at an acute angle. The one or more insert abutment surfaces are all rotated in the same direction, relative to their paired pocket abutment surface which in turn rotates a cutting insert abutting the cutting insert adaptor relative to an orientation the cutting insert would have if it only abutted the insert pocket instead of the cutting insert adaptor.

摘要： A rotary cutting tool includes a tool holder. The tool holder has holder body and an adjustment sleeve circumferentially disposed thereabout. The adjustment sleeve has an at least one sleeve adjustment groove which decreases in distance from a sleeve central axis in a rotational sleeve direction. The tool holder further has a plurality of insert cartridges, each having an insert pocket and at least one cartridge pin. At least one pin is located in a respective sleeve adjustment groove. The tool holder is adjustable between inner and outer adjusted positions by rotating the adjustment sleeve in the rotational sleeve direction. In the outer adjusted position, the insert cartridges are displaced in an outwards adjusted direction so that the insert pockets are radially outwards compared to the inner adjustment position.
