Milling

Milling By M & A Engineering

M&A Engineering Ltd offer a comprehensive range of portable milling equipment, with the capability of milling large areas in one set-up; optically set for accuracy.

The example below shows the linear machining of the 8 metre tracks of a bridge:

Each set-up covered an area of 2x3 metres and the track was accurately match blended at each move using an optical telescope.

In addition to the linear milling, a bespoke machine was designed and manufactured by M&A Engineering to undertake the milling of the radius tracks.

You can view a video of the Cantilever Bridge project by using the link on the right menu under general information.

Milling of Flat and Curved tracks on a Cantilever Bridge

M&A’s in-house designed, and propriety milling equipment can be applied to any site environment; for example: Petro-Chemical, Marine, Steel Production, Aggregate Production, Power generation etc.

Here, both the linear and radius milling machines can be seen working together on one side of the bridge.  Both machines are hydraulically powered and removed up to 17mm section of steel in a task lasting 24 hours a day for two weeks.

After the machining was completed, a total of 32 metres of new pre-formed wear plates were fitted to both of the linear and radius tracks.  Accurate machining ensured the bridge raises and lowers to a precise position.

Press Bed Milling

Note the severe distortion (top left photo) that has occurred to one side of a press bed. A portable milling machine is accurately aligned and set to other undamaged datums’ of the bed. Post machining has returned the bed perfectly flat and to the manufacturer’s original tolerance and specification.

On this new motor bed, the pads had to be machined flat and parallel to each other, on two levels. Again, optical alignment ensures machining to precise tolerances.

Vessel legs required precise reduction to a precise width. The machine is clocked to the existing face in both x and y axis, and then the leg is machined to the correct thickness.
