    The main objective of this experimental work is to evaluate and determine the wear of the abrasive wheel of silicon carbide in the process of plane grinding using front wheels on the surfaces in the aluminum heads, under the main parameters that influence said process. This work occurred in a low one a DOE experience design a factor factorial means of 2k is 4 factors at 2 levels, under the operating conditions in the grinding as: tool speed (rpm), speed of advance mm / min, depth of cut and refrigerant generating a total of 32 experiments with their replicas. The machine in which the experiments were carried out was the KR-1400 Rectifier of flat surfaces of engines (cabezote-blocks) of Argentine origin. The determination of the use was made based on the number of passes, by means of a probing clock together with a depth micrometer, guaranteeing a precision in the grinding, the operation was performed in the middle of a CAMRY balance with a capacity of 200 grams and a sensitivity of 0.01 grams, finally the measurement of the rectified surface was made with a rugosimeter Mitutuyo SJ210 is a reference to the standard ANS / ASME B46.1 Finally, the number of passes that could reach the grinding wheel abrasive car seat was six passes, with a G-use ratio of 49.87 by the use of coolant, while in the dry grinding five passes is the maximum level that I can reach, generating a wear ratio G of 35.36.
