Also found traces of deformation from the action of bending to the tungsten carbide inset cutter, depending on the orientation of its slip on the face. Fixing and rubbing, fretting-corrosion, damage to the local areas of the walls of the holes caused by scrolling the tungsten carbide inset cutter around its axis in the opening of the rolling-cutter teeth row. In the case of the use of tungsten carbide inset cutter with symmetrical exacerbation of the breeding part, the orientation of the creature's impressive head of the tungsten carbide inset cutter is determined by an effective angle to the axis of the crown of the tungsten carbide inset cutter pick. Calculations show that an angle of 45 ° is optimal.252-253entungsten carbidefretting-corrosionrollingcuttercrownroller conecutter bitsConference Abstract© Національний університет “Львівська політехніка”, 20172Slipchuk A.
