Reducing Surface Defects with MAM

Magnetic-abrasive machining (MAM) is a relatively new machining technique with great promise for a variety of applications. A Belarussian SME is looking to exploit its know-how in this field through new research efforts.
Reducing Surface Defects with MAM
Machining is an old trade, though the tools of the trade are changing rapidly. Technology has brought new levels of precision to the traditional machining processes of cutting, shaping, grinding, milling and polishing. Magnetic-abrasive machining (MAM) is an example of a new technique that can target sub-micron alterations.

With MAM, a magnetically abrasive powder is manipulated by a magnetic field to modify the object's surface. Amplifying the strength of the magnetic field results in a corresponding increase in machining power. The process can be automated and controlled through the use of computers.

MAM research in a laboratory setting by a Belarussian SME identified several advantages of this technique. The main benefit is that structural defects are much less common in MAM-machined products. These products also much more resistant to corrosion, wear and other hazards.

Furthermore, MAM can be applied to repair faulty production processes (e.g. etching) as well as to prepare surfaces prior to welding, soldering and/or coating. The process can also be used to clean materials of microscopic films and other unwanted substances.

Potential areas of application include the metals and ceramics industries, which feed into other industries such as shipbuilding, automobiles, telecommunications, household goods and many others.

MAM is economically competitive with other techniques, especially considering the improved material properties it achieves. However, further research is necessary prior to commercialisation of the technology. Partners and funding are sought for research opportunities to advance the understanding and commercial viability of MAM.
