The MCM – 5 axis portableshape cutting and welding machine

MCM advantages:

• Most processes can be performed in a fully programmable cycles.

• Simple and user friendly interface enables an easy input and configuration of cutting/beveling parameters. Innovative control system and software allow for double-sided beveling in one operation and ensures precise movement of cutting torch and active compensation of torch position with regards to work piece curvature.

• During welding processes system maintains programmed torch position.

• Cutting/beveling/welding on flat, concave, convex and conical surfaces is available.

• The MCM machine is fully portable.

• MCM can be firmly and quickly positioned with a set of magnetic feet.

• High quality and efficient double-sided beveling in one operation is possible.

• A multi language user friendly control system interface is available.

• Custom made versions are also available.

• Both SAW or FCAW welding methods can be implemented on the same unit.

Promotech’s portable cutting/beveling/welding machine is designed for cutting and beveling holes on flat, convex, concave surfaces, pipes, tanks and special conical shaped tubular structures such as wind towers.

The MCM machines enable programmable and complete both sided oxy-fuel or plasma hole cutting and beveling all in one set up and in most cases in one operation.

Optionally the MCM machine can be equipped with a welding head attachment for either SAW or FCAW applications such as door frames in wind towers.

The MCM’s advanced

control system makes

programming fast and

without need of any

external, costly CAD/CAM

software. It contains a

library of pre programmed

basic geometrical figures

such as rectangle, circle,

ellipse and rectilinear

ellipse. It also guides the

operator through all steps

of programming till the

whole job is defined.

Configuration of Welding Equipment

MCM can be equipped with SAW welding equipment (recommended).

On customer’s request the following devices (for SAW) can be installed to the MCM:

MCM can be integrated with power sources from different manufacturers in coordination

with the customer.

Integration for other welding technologies like MIG/MAG or FCAW is also possible on request.

• wire spool mounting system

• wire feeder

• welding controller

• power & control cables

• contact nozzle

• flux feeding system

• flux recovery system (option)

FORWARD

Programming process begins by choosing a required shape from built-in library. Next an operator inputs specific dimensions related to the job at hand. (Drawing No 1)

Then the operator chooses beveling type, defines the way of burning lead-in & lead out and determines basic parameters of cutting. (Drawing No 2)

Once the necessary data is entered, numerical controller of the machine generates the torch path and angles. If the hole to be cut has got its own individual oval shape the operator can “teach” the machine and customized the hole (see MSS in next page) (Drawing No.3)

RETURN

Operator can also transfer his own software in G-CODE format to MCM through USB port using a flash-type memory stick. (Available as an option)

Thanks to the 5th axis MCM

machine is able to operate with

constant bevel width.

MCM’s 5th axis controls torch

position with accuracy up to

0,1°, what provides precise

beveling angle and maintains

constant bevel width.

This very unique feature is highly valuable when beveling curved shapes on cone shaped convex or

concave structures. Constant beveling width with changing beveling angles is typically dependent on a

type of welding to be applied. MCM’s ability to maintain bevel width while changing the beveling angle

around the oval hole (e.g. manhole for wind towers) offers huge opportunities to save costs by

optimization of weld material deposition.

Typical beveling geometry:

Single bevel 1/3 – 2/3 double bevel Single bevelDouble bevel

MCM machine offers a new and unique feature. This new feature has been developed especially for the

wind tower industry. A special tool and software named MSS allows to “teach” the machine an imperfect

shape of an oval hole which needs to be cut, bevelled and welded. Door frames which are welded into wind

towers usually have their individual oval shapes which are far different from each other. Thus a need for

custom made shapes each time a door frame needs to be welded into a wind tower.

MSS - measuring slide system consists of:

•measuring arm,

•sliding clamp,

•main beam with linear scale.

•software

Operator places the aluminum beam with

perpendicular measuring slide on the doorframe

and makes width measurement at selected

points (both left and right side of the frame).

Then the measured values are entered into to the machine’s controller. Next the MSS software calculates

the exact hole shape and automatically generates the torch path.

It is cost effective, precise and quick way of doorframe shape programming. The whole operation can take

a couple of minutes and each time results in close to an ideal fit between beveled hole and door frame.
