1. GENERAL INFORMATION
1.1. Application
The BM-21S is a bevelling machine designed to bevel materials made of stainless steel.
The machine can bevel plates, as well as pipes with outer diameters of 150–300 mm
(6–12’’), at an angle of 0–60° and with the bevel width of up to 21 mm (13/16’’).
Additionally, the machine contains dampers to reduce vibrations.
When equipped with an optional guide, the machine can bevel pipes with outer
diameters of 300–600 mm (12–24’’).
