Abrasive Water Jet Machinery For Low Cost Miling

One of the main problems during milling is the unpredictability and uncontrollability of the depth of cuts. Now engineers in Spain have found a remedy for it. This new technique could enable low cost milling on difficult materials using water water-jet cutting machines. This may turn out to be a new break through in the fields like aerospace, marine, rail and automotive.



The equipment goes about the process by blasting the material with high pressure water and abrasive particles in order to erode and cut them. But it gets better than the traditional method because it does not produce hat but the traditional method produces heat damage with some materials like titanium. It is possible to even produce surfaces with variable depths by controlling the water speed and pressure and the geometry of the particles.

A research tem from research company Tecnalia and the University of the Basque Country and tried to predict the depths at different points based on the information on different processing parameters. In so many cases including certain materials can cause a high level of tool wear thus forcing the users to use expensive tools. AWJ can help overcome these problems, obviously because it prevents the heating up of the material and thus avoids any heat damage to the material. But as said earlier it is only for “certain materials” which tend to heat up when used with the traditional techniques. So, for materials like aluminium, which are not affected by the traditional methods, the traditional method can be used. That technique has been optimized for materials like Aluminium.
