Abstract

PROBLEM TO BE SOLVED: To make works at the time of attaching/detaching a work and changing a stage easy by freely ascendably and descendably mounting a chip scattering preventing cover on an elevating and lowering working unit. SOLUTION: Because a guide stay 6 lowers for a main body 1 when a working unit 2 lowers up to a working location, a cylindrical member 9 rotates a rod 7, sliding the rod 7. A cylindrical member 8 inserted into the rod 7 lowers a guide member 11 along a guide 10, lowers a cover 14 and is set to surround a work 5 on a bed. By this cover 14, chips and cutting agent do not scatter. When working is finished, the working unit 2 is elevated to an origin location and the cover 14 is returned. As a result, the possibility of an erroneous operation is eliminated and the cover 14 is safe because the cover 14 is moved in the vertical direction by the operation of a working machine without hindrance for a chip changing work on a tool rest 4 and a work mounting/removing work.
