Document Type and Number:
Japanese Patent JPH08502212
Kind Code:
A
Abstract:
A tool holder for use in a machine tool spindle comprising a shank portion, a tool mounting portion and a circular flange portion. Disposed in the distal end of the mounting portion is a central aperture while disposed in the distal end of the shank portion is a threaded aperture which communicates with the central aperture. The tool holder further comprises a cylindrical sleeve member which is slidably receivable into the central aperture when a heat source is applied to the mounting portion and rigidly maintained within the central aperture via thermal contraction when the mounting portion is cooled. A tool mounting aperture extends axially through the sleeve member which is in fluid communication with the threaded aperture. The shank portion of a cutting tool is slidably receivable into the mounting aperture when a heat source is applied to the sleeve member and rigidly maintained within the mounting aperture via thermal contraction when the sleeve member is cooled. Disposed in and extending axially along the inner surface of the mounting aperture is at least one channel for forming a coolant fluid passage between the tool holder and the cutting tool.
