Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
174 words
Travel device for a machine tool or a transfer machine, comprising: a frame provided with two parallel longitudinal components located on each side of a central passage and each provided with at least one longitudinal groove made in a lateral face located on the side opposite the other component, a slide mobile in travel, placed above said longitudinal components of the frame and provided with at least one pair of runners guided by balls and disposed opposite one another, each runner comprising a circuit of balls having a section along which the balls emerge laterally from the runner and are engaged in one of said grooves for guiding the slide, and means for displacing and positioning the slide along the frame, characterised in that the said longitudinal components of the frame comprise two separate rails (12), detachably fixed on the frame (1), and in that the slide (2) comprises control means for ensuring a prestressing of each runner guided by balls (15) in the groove (13) of the corresponding rail, towards the opposite runner.
Claim 2
Dependent Claim
