The work consists of three parts. In the first part, the upgrade of the vertical drilling machine model 2A125âs main drive unit is done according to the processed materials and structural formula, which are specified in the assignment. The drawings of the main drive unit and the spindle unit are based on the results of the calculations. The second part contains the technology of the âplugâ component manufacturing, as well as the description of the workpiece, machines, and cutting tools selection. Processing route is designed and technical documentation is compiled. The third part is devoted to calculation and designing of such cutting tools as prismatic profiled cutter, set of taps and hobbing cutter for cylindrical involute gears. Drawings are provided for each tool. Practical value of this work lies in an increase in the performance and efficiency of the machine. Additionally, the tools designed are intended to replace their import analogues.
