Disintegration and recycling possibility of selected abrasives for water jet cutting

Abstract

This paper presented a study of abrasive disintegration in a 400 MPa Abrasive Water Jet (AWJ). Abrasive particle size and distribution play a major role in machining and cutting efficiency of abrasive water jets. Tested garnet abrasive, commonly used in the abrasive water jet treatment, and corundum. It is of scientific interest to observe the disintegration of these particles which have been interactive with uncommonly used abrasive materials. Time impact of abrasive grains on the workpiece is very short and not all the grain in the stream of being able to do the work of cutting, you should expect the possibility of recovering the abrasive treatment. Considerable importance is the increase in cutting capacity crushed grains due to reveal new cutting edges. Based on a feasibility study this paper will present some results on achieved cutting data and shows also wear of the used focusing tube -the main part responsible for the formation of the jet.Keywords: Abrasive; water jet; grain size; recycling.Valoración de la desintegración y reciclaje de los componentes abrasivos en procesos de cortes con agua ResumenEste trabajo presentó un estudio de la desintegración abrasiva en un chorro de agua abrasivo de 400 MPa (AWJ). El tamaño y la distribución de partículas abrasivas juegan un papel importante en el mecanizado y la eficacia de corte de los chorros de agua abrasiva. Abrasivo de granate probado, comúnmente utilizado en el tratamiento con chorro de agua abrasivo y corindón. Es de interés científico observar la desintegración de estas partículas que han sido interactivas con materiales abrasivos poco comunes. El impacto del tiempo de los granos abrasivos en la pieza de trabajo es muy corto y no todo el grano en la corriente de poder hacer el trabajo de corte, debe esperar la posibilidad de recuperar el tratamiento abrasivo. Considerable importancia es el aumento en la capacidad de corte de granos triturados debido a revelar nuevos bordes de corte. Con base en un estudio de factibilidad, este documento presentará algunos resultados sobre los datos de corte obtenidos y muestra también el desgaste del tubo de enfoque utilizado, la principal parte responsable de la formación del chorro.Palabras clave: Abrasivo; chorro de agua; tamaño de grano; reciclaje.

Research into the Disintegration of Abrasive Materials in the Abrasive Water Jet Machining Process

“…This is the basis for comparison with the other abrasives tested: recycled garnet, corundum, and olivine. This study is an extension of the preliminary results published earlier in a much smaller scope [11].…”

“…A feasibility study of abrasive materials usage under a 400 MPa AWJ was presented by Perec [ 11 ]. Garnet and fused alumina were tested and preliminary results on the disintegration of these abrasive materials were shown.…”

Surface Topography Analysis of Mg-Based Composites with Different Nanoparticle Contents Disintegrated Using Abrasive Water Jet

“…WJ is currently used mainly for the disintegration/machining of materials with special mechanical properties, including titanium alloys [ 7 , 8 ], difficult-to-machine alloys [ 9 ], rocks [ 10 , 11 ], glass [ 12 , 13 ], graphite [ 14 ] and different composite materials [ 15 , 16 , 17 ]. Technological parameters [ 18 , 19 ] have been studied in order to achieve the required surface quality in the disintegration of static [ 20 ] and/or rotating workpieces and to apply WJ and AWJ technology to the field of precision machining [ 21 ], especially difficult-to-machine and thermolabile materials [ 22 , 23 , 24 ]. Experimental analyses of topography and AWJ technology-related causes of roughness and waviness of the machined surface have been investigated in previous studies [ 25 , 26 , 27 , 28 ] in order to predict the surface roughness quality, which is also necessary for newly developed materials, including metal matrix nanocomposites (MMNCs).…”
