MCM | 5-axis portable CNC cutting & welding machines

Why MCM for doorframe cutting and welding ?

Promotech’s MCM machines are a true portable CNC cutting and welding machines. They can work on
round, conical or flat surfaces as well as on multi-surface parts. These machines are designed and manufactured by Promotech and are made of highest quality European parts.

The application of a door frame to a wind tower, which requires cutting, beveling, assembling and welding processes, is a time consuming operation that deeply affects the manufacturing cycle.

Promotech’s MCM Machines – Portable CNC Oxy-Cutting & Beveling and SAW Welding accepts two technologies that apply door to tower:

■ Door frame welded directly on tower
■ Door frame welded in a rectangular plate, which is then welded in the tower section
■ Cutting & Beveling openings in Big-size Monopiles, and maximum plate thickness up to #150 mm

and It’s One-man operation.

In all cases MCM machines produce perfect joints, door frame fit up and MCM SAW welds in “full penetration” class acceptability level B according to ISO 5817. Less than 1% of welding defect rate and no grinding by finished welded seam of the door frame inside and outside tower section it’s confirmed by customers in Wind Business.
