A circular sawing machine for sawing panels with continuous longitudinal adjustment of the play between a carriage and the guide rail

摘要

A circular sawing machine for panels (1) comprises a base (4), a carriage (2) which moves on a rail (6) by means of bearings (7), a fixed table (3), a disk-shaped cutting tool (5), and has a longitudinal groove (C) in the rail (6), next to a race (p) for the bearings (7) on the rail (6), where the groove (c) has a surface (15) which when subjected to thrust transversally deforms the adjacent race (p) to adjust the preloading on the bearings (7); there also being elements (12) which may be inserted in the groove (c) and tightened in an adjustable fashion using means (14) against the wall (15) of the groove. In the machine, the elements (12) which may be inserted in the groove (c) are sections of a bar (13) which are longitudinally aligned without interruptions.
