Process for making sectionalized precision components

In a process for fabricating precision components of the type comprising a member which is of a sectionalized construction including a plurality of sections joined together in assembled condition at an interface defined by a respective parting surface of each section, the steps of forming a plurality of sections having a shape and size such that the assembly thereof at the parting surface of each section substantially defines the sectionalized member, applying a thin film of adhesive to at least one said parting surface at each interface, adhesively securing said sections together at the interface defined by the respective parting surface of each section into a bonded assembly in which the sections are disposed in an assembled relationship corresponding to their ultimate operating disposition, finishing at least some of the surfaces of said bonded assembly including a surface incorporating an exposed edge of said interface to the desired final dimensions and surface finish, and thereafter cleaving said bonded assembly and separating the mated finished said sections.
