Stone slab edge trimming machine - has work carrier travelling past fixed head and adjustable frames under working surface

摘要

The machine for trimming the edges of stone slabs has a wagon travelling on rails (9) which moves past a fixed grinding head (1,23) mounted on a vertical column (4) for height adjustment alongside the rails. This wagon has a support surface (6) for the workpiece, mounted on an adjustable arrangement for aligning the workpiece. This arrangement includes a lower frame (11) with one end located by a vertical spindle (12) so that it can be swung about a vertical axis. Above this is an upper frame (13) also located by the spindle, for clamping the workpiece (5). The frames are swung by rotating a handwheel (20) projecting sideways, operating a screw and nut drive. Guide runners (17) are located in the space between the upper and lower frames.
