The object of this dissertation is to analyse a drilling process of an automatic horizontal boring machine the SVD2 for drilling of bearing holes. There were problems with vibrations during drilling process, causing an extreme noise and this dissertation solves them. First of all it was necessary to analyse the vibrations, to examine a machining process and measure machine dynamics and statics. Another task was to compare measured results with mathematical models and after their analysis to design structural and other solutions. The SVD2 machine was designed on the basis of a previous type the SVD. Its conversion to a new one was based on adding of six spindles. As a result a number of drilled bodies was increased from one to four, so a performance was increased four times. That is why there was an original intention to rebuilt the other two spindle machines. To leave the basical parts of the machine without any modification ( such as a reinforcement of a mount and adjusting of a bigger distance of a side linear spindle guideway and a cross linear guideway of a support for clamping devices), would be unsuitable solution, which was confirmed after a measurement and a following analysis.
