description: Final qualifying work of the bachelor on the topic: "Design and technological and tool maintenance of metal working on drilling machines based on the model 2A125" consists of: 84 pages, 21 drawings, 35 tables, 15 bibliographic sources, 10 applications. The technological documentation package includes: a technological chart (9 sheets A4), an operating chart (20 sheets A4), a sketch map (20 sheets A4), control chart (2 sheets A4).
 Final qualifying work consists of three parts.
The first part is devoted to the modernization of the drive of the main movement of the vertical drilling machine 2A125. Based on the given processed materials, cutting speeds were calculated, which further allowed to obtain a graph of frequencies, as well as to choose the necessary motor that meets the specified conditions. On the basis of the schedule of frequencies was selected toothed wheels with the desired gear ratios. Further calculated torque and power on the shafts of the designed drive, as well as modules, width and diameter of the gears. The test calculation of gears for contact endurance and bending was carried out. Selected spline connection with their verification by calculation according to voltage collapse. Rolling bearings are selected. The lubrication system is designed. Based on all of the above, a drawing of the main motion drive of the universal vertical drilling machine based on the model 2A125 with the specification was developed.
The second part is devoted to the calculation and design of cutting tools: shaped disc cutter, a set of taps, worm cutters for cutting cylindrical gears. For each tool, the required geometric parameters are calculated, on the basis of which the drawings are developed.
The third part is devoted to the design of the manufacturing technology of the part "Axle", for which the main technological tasks are defined, design and technological bases are identified. The method of forming the workpiece is described in detail, the workpiece itself and the route of its processing are designed, the equipment and the cutting tool are selected. Cutting conditions are determined and a set of technological documentation is issued.
