Multi-spindle drilling machines are widely used in economic mass production. In use are two different layouts:A horizontal or preferred a vertical multi-spindle drilling machines. The main representatives of this group of machines, in addition to frequently used spindle drilling machines, are articulated spindle boring machines, equipped with adjustable spindles. They can be adjusted easily to process the desired hole pattern. In this way, to process a plurality of simultaneously drilled holes within predetermined machine intervals is possible. Multi spindle drilling machines do not offer this flexibility in processing. Their spindles are arranged rigidly. Therefore, this type of machine is only used in high volume production.
