METHOD AND MECHANISM CAPABLE OF DISENGAGING OPTIONALLY CONNECTION OF FLYYWHEEL ON MAIN SHAFT OF AUTOMATIC TOOL EXCHANGING SYSTEM MACHINE TOOL AND MAIN SHAFT

摘要

The present invention relates to an improvement in a mechanism wherein a flywheel which is idly mounted on a spindle of a machining center is easily and speedily connected with or detached from the spindle by a clutch which is fitted on the spindle adjacent to the flywheel for promoting the cutting efficiency by providing spindle inertia of two kinds; one kind for heavy cutting and another for light cutting respectively.
