Abstract

A multispindle machine tool, characterized in that outside cylindrical members (19) having a plurality of spindles (2) and fixed to a support frame (3b) are inserted into the center holes (2c) of the spindles, a mist generator (22) for generating lubricant mist in the spindles and inside cylindrical members (20) having the mist generator fixed to the tip thereof are installed on the inside of the outside cylindrical members so as to be withdrawn the outside cylindrical members held in fixed state so that, under the installed state, the mist generator can generate the lubricant mist since compressed air and liquid lubricant are separately fed from the outsides of the spindles thereto through the outside cylindrical members and the inside cylindrical members and the inside cylindrical members and, under the withdrawn state, the lubricant mist is fed from the outsides to the insides of the spindles through the outside cylindrical members to jet out the mist from the tips of the cutters fixed to the tips of the spindles, whereby a mist generation system can be changed from an internal mist generating system to an external mist feed system by a simple operation, and the optimization ope…
