FIELD: mechanics.
SUBSTANCE: invention is referred to mechanical engineering, particularly to drilling jig manufacture. Manufacture method of high-accuracy roll-over-box jig for drilling even number of equally distanced radial holes includes lathe turning and marking of half of the total number of holes on the assembly. Reference item is installed into assembly and guiding holes are drilled in the direction from the inner to outer diametre using reference item as a jig. The screw plugs are threaded into holes and drilled using pre-drilled holes and reference item as the jig.
EFFECT: increased accuracy of jig manufacture using simple machine equipment.
