To this end, the invention consists of a headstock carrying the usual bearings, a spindle fitted therein7` a face gear keyed or fitted to turn with the spindle but so as to permit axial adjustment between the spindle and gear, a bearing sleeve keyed or fitted to turn with the spindle but so as to permit axial adjustment between the spindle and sleeve, a driving pulley and connected pinion fitted to turn on said sleeve and means for adjusting said spindle axially. This construction is particularly adapted for use in back geared headstocks and particularly where the machine tool with such headstock is used as an instrument of precision. |
