The article considers the structural optimization results for the process of mechanic removing inside flash during the production of longitudinal electric-welded pipes with a diameter of 60.3 ... 89.0 mm. Mechanical processing was performed with a pipe electric welding unit, designed for the manufacture of pipes with a diameter of 60.0 ... 178.0 mm, using various cutting tools and grades of hard alloys. The influence of the parameters of chip formation and cutting forces on the quality of inside flash removing in a longitudinal electric-welded pipe is found. The experiments were carried out using both the basic and experimental geometry of the cutting tool. The dependence of the tool durability at the operation of flash removing on the hardness of the alloy and the wear resistance of the coating has been studied. The analysis of the results of the study of annular inserts made of a three-carbide hard alloy with a multilayer wear-resistant coating showed the possibility of reducing the consumption of cutting tools and emergency stops of the mill, improving the quality of processing and the rate of yield.
