Feeding mechanism of digital-controlled lathe driven by linear electric motor

The utility model relates to a feeding member of the machine tools, in particular to a feeding member of the CNC lathe which is driven by the linear-motor, comprising a slipway which is arranged on the mover of the linear-motor; a knife rest is positioned on the slipway; a linear-motor stator is positioned on the base; a linear guide rail seat is connected with the slipway. The mover and the stator are positioned in the space formed between the inner side of the two lead rails and the underside of the slipway, which are horizontally arranged. The utility model mainly solves the technical problems that the general CNC lathes can't process the non-circular parts, effectively solves the problems of the sealing, the anti-magnet, the rejection of heat, and the safety protection; and, with the aid of the linear rolling guide rail of high accuracy and the raster ruler feedback elements, as well the measures to optimize the structure design and reduce the motion inertia, the utility model improves the response speed and the feed position accuracy of the feed movement.
