MCM 5-axis portable CNC cutting & welding machines

MCM 5-axis portable CNC cutting & welding machines


The MCM series by Promotech consists of unique 5-axis portable CNC machines specifically designed to automate the most labor-intensive processes in wind tower production (both Onshore and Offshore). These machines combine 3D scanning, oxy-fuel cutting with beveling, and automated Submerged Arc Welding (SAW). The MCM is mounted directly onto the tower section, eliminating the need for costly transportation of oversized workpieces to stationary portal machines.

Features & Benefits

  • Automation Without Programming: The integrated scanning system automatically detects the individual shape of the workpiece (e.g., door frame aperture) and generates the CNC cutting and welding paths. No prior CNC programming skills are required.

  • Top-Quality Weld Preparation: Ensures a precise root gap of 1–3 mm, reducing welding defect rates to less than 1% and completely eliminating the need for post-process grinding.

  • CNC 3D Oxy-fuel Cutting: A specialized head enables complex 3D beveling for a perfect fit of door frames.

  • High Economic Efficiency: One-man operation and high deposition rates (up to 11.6 kg/h) significantly reduce labor and overhead costs, ensuring an excellent Return on Investment (ROI).

  • True Portability: Short setup time and easy handling allow for operation directly on the shop floor with available online support.

Standard Equipment

  • 5-axis Mobile Platform with an integrated CNC control system.

  • Advanced Laser Scanning System for generating individual 3D surface profiles.

  • 3D Oxy-fuel Cutting & Beveling Head for high-quality edge preparation.

  • Simple MCM Control Interface that requires no costly operator training.

  • Specialized Mounting System for secure installation on curved tower sections.

  • Technical Support Package: Recommended parameters for oxy-cutting and SAW welding.

Options

  • SAW AC/DC Welding Head: For automated submerged arc welding (inside and outside) to boost productivity.

  • Model Variations based on Tower ID: Choice of models ranging from the compact MCM Mini to the heavy-duty MCM 5000+.

  • WPQR/WPS Development Support: Assistance with the development and certification of welding procedures.

  • Online Support Connection: Remote diagnostics and real-time technical assistance.
