Abstract
A tool body includes an insert seat for receiving a cutting insert for chip-removing machining. The insert seat includes a bottom surface and support surfaces upstanding from the bottom surface. Each support surface comprises at least three ridges separated by grooves. Each groove has a depth greater than zero and no greater than 0.015 mm. An insert mounted in the seat by a screw has a center hole whose axis is offset from the axis of a threaded hole of the body in which the screw is connected. That offset distance creates a prestress of the insert toward the ridges. The depth of the grooves (i.e., the height of the ridges) is substantially less than the distance of the offset.
Claims13
A tool body including an insert seat adapted for receiving a cutting insert for chip-removing machining, the insert seat including a bottom surface and support surfaces upstanding from the bottom surface, each support surface comprising a plurality of ridges wherein adjacent ridges are separated by a groove having a depth greater than zero and no greater than 0.015 mm;
- and wherein said groove has a width (b1) separating said adjacent ridges from one another, the width being in the range of 0.1</=b1 </=0.4 mm.
A tool for chip-removing machining comprising a tool body including at least one insert seat in which is disposed a cutting insert for chip-removing machining, the at least one seat including a bottom surface and support surfaces upstanding from the bottom surface, each support surface comprising a plurality of ridges, wherein adjacent ridges are separated by a groove having a depth greater than zero and no greater than 0.015 mm, wherein the insert is carried by the bottom surface and abuts against ridges of each support surface;
- and wherein said groove had a width (b1) separating said ajdacent ridges from one another, the width being in the range of0.1</=b1</=0.4 mm.
