In this paper, based on three different processing equipment, aiming at the processing of five spiral ball grooves of tractor brake pressure plate, three processing schemes are formulated, which are ordinary machine tool, numerical control machine tool and modular machine tool respectively. Through the analysis of the implementation process of the scheme and the comparison of processing characteristics, the preliminary scheme 3 adopts the combined machine tool processing scheme as the alternative scheme From "guarantee of machining accuracy, calculation of man hour quota to calculation of equipment load rate", the applicability, feasibility and superiority of the scheme are further verified. It has a certain reference significance for the formulation of similar parts processing scheme.<br>
