  • Guide channels are introduced in a known manner by mechanical processing on machine tools or transfer lines, ie drilled. These are done in several elaborate, high-precision work steps Central main ducts and sidetracking channels, which make junctions to individual needs sites, are drilled into the component. Subsequently, numerous, unnecessary accesses must be closed permanently and safely. Very long, linear guide channels, such as those of the main oil passage in a cylinder crankcase are today even occasionally poured by pouring a pipe or by saving by a corresponding casting core.
