Abstract

A combined grinding, notching and marking machine can represent a valuable and economic alternative to a definite grinder for those wire producers with a limited rebar output or for larger manufacturers in search for a flexible back up unit. Our new AT710EN CNC combined machine is able to perform basically four different operations: a) notching according to all international standards with a quick and reliable technology, considering that the machine will be engaged 100% on tungsten carbide rings; b) fast marking of numbers, letters and logos and with the lowest possible tool costs; c) frinding with plunge or contour methods using either standard diamond bonded or larger electroplated wheels; d) centering the groove, the notches and logos and measuring the results of all these operations. These four different functions are performed by four different devices. The quick change of the functions and their accuracy and repeatability are granted by of a rotating head that travels on two digitally controlled axes and that is able to lodge the four dedicated equipment. The machine is governed by our renowned Rollwork® interface that is able to control, with a very user friendly approach, all the functions of the machine and to manage a useful roll database as well. This machine can execute each single task with the same efficiency and accuracy of the corresponding single machines. Therefore, also in this case, the choice between selecting this combined machine or two dedicated machines is just influenced by economic considerations and specific plant requirements.
