MACHINE TOOL EQUIPPED WITH MOVABLE COVER

摘要

The machining space of a machine tool is covered by a cover. A wall section is arranged on the bottom section of the cover of a machine tool, in such a manner that there is a slight gap between the telescopic cover and the side faces of the wall section. Since the gaps between the side faces of the wall section and the side faces of the telescopic cover are small, then it is possible to prevent cutting chips from going into a space beneath the telescopic cover and accumulating under the telescopic cover.

主权项

1. A machine tool, comprising:
a saddle which is supported on a first guide member provided on a bed and which moves relatively in a first direction with respect to the bed; a table which is supported on a second guide member provided on the saddle and which moves relatively with respect to the saddle in a second direction intersecting with the first direction; a column having a spindle; a cover which covers the periphery of the bed; and a movable cover which is provided on both side faces or one side face in the first direction of the saddle, both ends or one end thereof being fixed to the cover and the movable cover being formed to be able to perform a telescopic motion in synchronization with the movement of the saddle, wherein the cover has a front face cover provided on an opposite side to the column with the table interposed therebetween, side face covers provided to the left and right of the front face cover, and a bottom section which is connected to the bed from the front face cover and the side face covers, and a workpiece is machined by causing a tool installed on the spindle and the workpiece which is set on the table to move relative to each other, and wherein a wall section which projects upwards from the bottom section and extends long in the first direction is provided in the bottom section of the cover, inside the movable cover.
