The CM1S automatic cleaning machine carries out the cleaning of the PVC corner weld bead by combining a cutter unit and two knives for the upper and lower part of the frame. The specially shaped cutter units are equipped with a quick change to facilitate the changeover operation. The knives fit the surface of the profile thanks to a self-levelling system.

The whole working cycle is coordinated by an internal PLC that controls the clamping of the welded frame and starts the cleaning cycle. CM1S is equipped with two useful arms for the support and the management of the frame rotation. The machine, properly equipped with the necessary tools, can work all types of standard profiles, acrylic and coated.
