AUTOMATION OF MACHINING OF THREADED HOLES OF ULTRA-SMALL DIAMETERS

We study the process of automating the production process when threading in holes of ultra-small diameters (d ≤ 1,4) in aluminum alloy parts in high-performance machining centers. The proposed schematic diagram of the processing of the threaded hole midget diameter for high-performance machining centers with the use of cutting blade anode-mechanical processing (AMO). Advantages of the offered scheme of processing in comparison with traditional methods that allows drawing a number of conclusions were shown. Application of the proposed scheme of blade anodic-mechanical treatment allows to increase the reliability of the processing’s threading operation in the holes of ultra-small diameters compared to the traditional scheme of processing with the use of lubricating coolant, and also allows you to automate the process of threading in holes of ultra-small diameter
