【発明の名称】カートリッジタイプの高速フライス
Document Type and Number:
Japanese Patent JPH10508259
Kind Code:
A
Abstract:
A cartridge-type milling cutter is provided having a cartridge mounting mechanism that resists the centrifugal load applied to the cartridges at high rotational speeds. The milling cutter includes a generally cylindrical cutter body, at least one replaceable tool cartridge having a trailing face, and a leading face having a cutting insert for cutting a workpiece, and a mounting mechanism for detachably securing the tool cartridge onto the cutter body. The mounting mechanism includes a recess in the cutter body for receiving the cartridge that includes a radially canted wall for providing dovetail-type resistance to radial movement of the cartridge, and at least one compressively loaded set screw in the cutter body for compressively engaging the leading face of the cartridge in order to seat and retain it within the recess. During the operation of the cutter, the centrifugal load is substantially borne by the combination of the radially canted wall and the set screw. The mounting mechanism preferably also includes a screw, optionally radially-oriented, that passes through a through bore in the sides of the tool cartridge for providing additional insurance against the loosening or breaking away of the cartridge during high speed operation.
