Abstract:
The article considers the improvement of machining process, namely thread cutting with screw taps, improving quality and stability of roughness of the thread surfaces of high speed cutting steel tools. A scheme of magnetic abrasive polishing and a method of selecting operating conditions of screw taps machining. In the process of elaborating the conditions of the magnetic abrasive polishing process it became clear that one needs different processes for shaping major and minor cutting edges of the taper leads, the sizing parts and the lead-in sections of screw taps. Key words: threaded joints, surface roughness, magnetic abrasive polishing, polishing conditions selection, thread quality.INTRODUCTION
