The machine is designed for cleaning the corners of PVC profiles after welding. It offers high durability and reliable operation for different profile thicknesses. All PVC profile corner cleaning operations are combined in one computer controlled CNC machine. The system supports simple DXF programming, automatic lubrication, USB file transfer, and optional network access for remote control. It can optionally be connected to a two-axis robotic turning station and adapted to a four-head welding machine.
