How Electron Beam Machining Process Works? In order to cut harder materials like metals or granite, an abrasive material is mixed in the water. A key factor in precision is software—not hardware. Water jet machining is a relatively fast process. It may be considered as a vertical shaper. The fluid jet drags the abrasive through the material in a curved path as the fluid lags the nozzle. The flow of the water is regulated with the help of the flow regulator. It stores the high pressurized water temporary. Plastic materials to be separated can be foils and seals. As an industry with no margin for error, the aerospace department emplo… Hard materials are normally cut up to 150mm thick. It varies with the softness or hardness of the material being cut. Good software can increase cutting speeds dramatically. Waterjet cutting is the process where by a jet of water traveling at ludicrous speed (produced by putting water under high pressure and forcing it through a small orifice) cuts through materials by eroding the material away at the point of contact. Your email address will not be published. The slotter or slotting machine is also a reciprocating type of machine tool similar to a shaper. The pump delivers water to the intensifier at low pressure of about 5 bars.
