ABSTRACT:
The invention relates to a travel device in a machine tool having a travel slide (2) which supports a machining unit (4) and which is mounted on a frame by means of runners having balls. Frame (1) is fitted with two parallel rails (12) having a wide-mouthed groove (13) on their outer face. A base plate (3) of the slide (2) has on its lower face four runners guided by balls (15) comprising a section where the balls (16) project so as to be engaged in the groove (13) of the rail. The runners (15) are protected from machining scraps. They are also prestressed by adjusting screws (24) so as to exert permanent pressure on the rails. Such a device can be used in all machine tools or transfer installations fitted with a travel slide.
