Study Of The Generation Of Microburrs In The Process Of Drilling And Its Subsequent Elimination By Deburring, Of Tubes Cylindrical Aluminum AA6065-T9

Abstract. Creation of microburrs drilling constitute a potencial danger because their detachment can modificate the correct operation of a mechanism. The burrs must be eliminated completely in the case of pistons brake, ensuring a high productivity and a low cost. In this work has been studied the mechanism for the creation of microburrs in thru holes drilled ((|)2,02 mm) of a aluminium alloy piston AA6065-T9 in order to various parameters such as the type of drill bit, feedrate, cutting speed and lubrication, imposing a minimum feedrate of 450 mm/min not to reduce the current production. Creation of microburrs drilling is inevitable and several deburring processes have been analyzed for their total elimination. After a few first essays. It has been determined that in order that the deburring are effective must be worked with minimal and known position burrr drillings
