Abstract
Disclosed is an enclosure or housing for a machine tool that includes a rear wall, two side walls, a top wall and a partial front wall. A door, is positioned above the partial front wall and covers that portion of the housing not covered by the remaining walls. The door is constructed in two sections with one section lying above the other in a closed position. The two sections are preferably joined by a hinge, and a door is opened by lifting the bottom section in an upward direction which thereby causes a top section to also lift until the rear faces of the top and bottom sections meet at an acute angle. A pair of rollers is connected to the lower section and the roller will roll on a track on the side walls while at the same time the upper section swings on the hinge which connects the upper section to the top wall. A door counterweight facilitates the lifting of the door and maintains the door in an open position.
