The present paper presents a relatively new technology called rotary broaching for processing external and internal profile surfaces –. The technology can be implemented on lathes (turning centers, multi-task machines) and milling machines with CNC, using a special holder with a tool having the geometry of the processed profile surface installed on it. The tool holder has a specific geometry, providing an angular location of the tool axis relative to the machined surface of 1֠, offering the possibility of machining. One of the main advantages of this technology is that it allows the processing of profile surfaces in blind holes and closed external surfaces, for example, on the steps of rotating parts. It requires preliminary preparation of the treated surface, where for internal profile surfaces, it is necessary to process a starting hole with a certain diameter and length, depending on the size of the profile surface. Furthermore, processing by this technology implies obtaining high productivity, as it works with feed for a speed of 0.01 ÷ 0.12 mm/rev and spindle speed (workpiece) 1000 ÷ 3000 min-1 depending on the processed material. According to the manufacturers of tools used for a rotary broach, various types of material with tensile strength Rm up to 1400 N / mm2 can be processed, such as stainless steel, cast iron, aluminum and copper alloys, titanium, brass, and others.
