Selection of Means of Work for Mass Production of Increased Quality Openings With Assembly Works

Modern mechanical engineering sets up new demands regarding accuracy and quality of parts, which positively influences its perfomances, and subsequently the production of precise orifices. There are numerours and justified reasons for the productions of the precise openings in mechanical engineering, espacially in modern aircraft and rocket industry. Certain construction of brouches and devices allow the production of the precise orifices, even at unaviable places. Replacing drilling, reaming and other less effective methods of producing precise openings, broaching at assembly operations in one of current issues of airplane parts assembly technology. Despite to relatively expensive broaching production, the simplicity of treatment process with high preciseness and productivity, this treatment has large applicability. The paper deals with checked results in production conditions
