Drilling technology solution in the maintenance center of small firms

The basic characteristics of the drilling technology, view of tools for drilling, descriptions of the parts and angles of twist drill are described in the first part of this project. In the second part of this project there are descriptions of various drilling technologies, the choice of cutting conditions and the choice of cooling and lubricating emulsions and oils. The range of tools, machinery and clamping equipment in the workshop machinery maintenance sugar factory in České Meziříčí are described in the next part of the project. Also specific technological conditions for the production of precision holes (with a use of a calculator) was determinated. After that their production was performed. In the end the possibilities of production machinery maintenance workshops during production of holes using drilling tools are shortly valorized
