Embodiment Construction

[0013] see now figure 1 A cutting tool 10, such as a milling cutter, includes a body 11 having a pocket 12 and a wedge clamping system (generally indicated at 13) according to an embodiment of the present invention. It should be understood that the cutting tool 10 may include any number of pockets 12 and that the invention is not limited by the number of pockets 12 shown in the illustrated embodiment. Each pocket 12 is capable of receiving the figure 1 The insert chuck 14 and clamping wedge 16 are generally shown in FIG. The insert chuck 14 and clamping wedge 16 constitute the wedge clamping system 13 of the present invention.

[0014] Generally, the pocket 12 includes a top wall 18, a bottom wall 20, side walls 22 for engaging the blade cartridge 14 ( Figure 5 ) and rear wall 24. The rear wall 24 acts as a stop for the blade cartridge 14 when the blade cartridge 14 is mounted in the recess 12 in the locked state. The top wall 18 has a first portion 18a formed at a first...

Abstract

A cutting tool includes a pocket with a top wall, a bottom wall, a side wall and a rear wall. The cutting tool has a wedge clamping system that includes an insert cartridge and a clamp wedge. The insert cartridge includes a recess that interacts with a protrusion on the clamp wedge in such a way that the clamp wedge exerts a force vector in an axial direction when the clamp wedge is threaded into the pocket, thereby reducing deflection of an adjacent pocket of the cutting tool when the cutting tool is placed in a locked condition.

Description

technical field [0001] The present invention relates to the field of cutting tools. More particularly, the present invention relates to cutting tools having a wedge clamping system that resists centrifugal forces to securely retain a cutting insert in a pocket of the cutting tool during cutting operations. Background technique [0002] Conventional cutting tools with insert cartridges use a variety of methods to mount the insert cartridge to the tool body. One known method of clamping an insert cartridge in a cutting tool pocket is to use a clamping wedge. Unfortunately, due to centrifugal force, the insert cartridge has a tendency to fly out of the pocket at higher cutting speeds, increasing replacement times and associated costs. Contents of the invention [0003] The problem of securely clamping the insert cartridge in the pocket of the cutting tool is solved by providing the cutting tool with a wedge clamping system which resists centrifugal force to securely hold th...
