GUIDING PROCESS OF A MATERIAL BLANK IN A MACHINE-TOOL, MACHINE-TOOL IMPLEMENTING THIS PROCESS AND CORRESPONDING GUIDING DEVICE

摘要

The invention relates to a guide device (10) for guiding at least one edge of a material blank in a machine tool, said device comprising a body (11) provided with a mounting section (12) and a guide section (13), and retaining means (20) for maintaining said guide device in the work table (2) of said machine tool. The retaining means (20) are provided on the side of said guide section (13) to be accessible from above the work table (2) and to facilitate interventions. The guide section (13) comprises a guide zone (ZG) provided with a guide groove (15) and a free zone (ZL) devoid of the guide groove, these two zones (ZG, ZL) being angularly offset to define two mounting positions of said guide device: a guide position and a retracted position simplifying the maintenance operations and / or the implementation of said material blank.
