Improvement of Tool Life on Cutting Stainless Steel with the Internal Cooling Method

When stainless steel, a difficult work material, is cut, cutting forces increase and cutting temperature rises significantly. Consequently, the tool life of high-speed steel becomes markedly short. To reduce the cutting temperature, the tool is cooled internally with water, and to reduce cutting forces, high-velocity cutting oil is applied. With the method of cooling and lublication technique tool life becomes far longer, compared with that in ordinary cutting. Accordingly, this procedure would be very effective for cutting other difficult work materials
