The smartLine variant is a flexible, modular machine concept. "The secret of our smartLine range is its modular structure," points out Dr. Markus Stanik, managing director of Elb-Schliff. "We leverage a modular machine kit for the customized assembly of both surface grinding and complex profile grinding machines."

The BG series machines are equipped with a moving table or traveling column, depending on the workpiece, and are designed for grinding complex and large tools such as broaches. Depending on machine size, the components have lengths ranging from 1,000 mm at a workpiece diameter of 10-200 mm up to a maximum workpiece length of 3,000 mm and a diameter of 600 mm.
