Modification of cutting tools by drag finishing

Abstract

The paper deals with a progressive method of modification of cutting tools by drag finishing process. The subject of the research is the dependence of the drag finishing time on the size of the cutting edge radius. The milling tool – solid cemented carbide mill was made on a tool grinder REINECKER WZS 60. The cutting tool was drag finished on the OTEC DF-3 TOOLS drag finishing machine. The measurements of cutting edge radius was performed on two devices: 3D optical microscope ALICONA Infinite focus G5 and contour and surface measuring machine ZEISS SURFCOM 5000. The results of the measurements are evaluated at the end of the paper.
