Contact Arm

Atlas Copco contact arms determine the working pressure and contact geometry between the abrasive belt and the workpiece on belt sanding tools. Selecting the correct contact arm profile, flat, serrated, or radius, for the surface being finished directly influences cut rate, surface finish quality, and belt life. Genuine Atlas Copco contact arms are dimensioned and hardened for the specific tool model to ensure consistent sanding performance.
