The machine can process bullnose profiles between 15 and 60 mm in thickness, which are obtained by the use of standard plane diamond wheels and do not require the use of profiled tools. The engagement and disengagement of the abrasive on the edge to be polished can be programmed even in the presence of irregular work pieces, and polishing of straight edges has been improved by the introduction of gentle rocking movement of the heads (plus or minus 2 degrees). With the use of a special diamond tool, a light bushhammering type finish can be obtained on straight or bullnose edges up to a maximum thickness of 60 mm. The frontal bar is no longer required, and the forward and reverse pressure controlling the abrasives is independent and does not require counter pressure. The conveyor belt slides over an interchangeable wear-resistant stainless steel surface and is fitted with a square cross-section guide way recessed into the work surface near the pressure units, thereby avoiding belt displacement during processing operations.
