Abstract
Abstract An apparatus for cutting holes in structures and details having cylindrical surface with the aid of a cutter mounted with a possibility of simultaneous displacement in horizontal and vertical planes, in accordance with a mode set by a profiling device whose cams are placed on both sides of the cutter and are connected with the latter by means of a rod pivotally connected to the cutter and the cams, which rod, capable of tilting in a vertical plane, serves to maintain the cutter position at the level of a preset distance between the cutter and the surface of a structure in which a hole is being cut.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
121 words
An apparatus for cutting holes in structures and details having cylindrical surface, comprising: a cutter mounted with a possibility of simultaneous displacement in horizontal and vertical planes; a profiling device adapted to set the mode of the vertical displacement of said cutter; profiling cams of said profiling device; members serving to connect said profiling cams with said cutter, in which members said profiling cams are mounted with a possibility of unobstructed vertical movement independent of each other; a rod serving to additionally couple said cutter and said profiling cams, both the cutter and the cams being connected to said rod by means of pivot joints, the pivot joint of said cutter being mounted with a possibility of displacement along said rod.
