Abstract: To provide a control panel for machine tools that improves operability and enables even an unskilled person to easily grasp a procedure for moving a screen to a target screen. A plurality of screen data are classified into a plurality of groups and classified into main screen data and sub-screen data associated with the main screen data in each of the groups. A control section displays the main screen data and displays the sub-screen data on a display section according to a type of an input to a plurality of main screen corresponding buttons.

Abstract: A machine having a vertical main spindle include a bed having a bottom portion and a pair of walls arranged uprightly from both ends of the bottom portion, the sidewalls having horizontal upper mounting surfaces thereon. A first slider is slidably horizontally mounted on the upper mounting surfaces for movement along a first axis. A second slider is slidably horizontally mounted on the first slider and guided by a pair of guide rails arranged on the first slider for movement along a second axis perpendicular to the first axis. A jig apparatus is mounted on the bed for clamping a workpiece at a position lower than the first slider. A spindle head that vertically supports a main spindle is mounted on the second slider so that the main spindle is moved along the third axis perpendicular to the fist and second axes between the guide rails.
