ホブ切り用水溶性切削油剤に関する基礎的研究 : 第1報,不水溶性切削油剤との性能比較(機械要素,潤滑,工作,生産管理など)

This paper deals with the performance of water-soluble cutting fluid for hobbing in terms of tool life (flank wear), crater wear and finished surface roughness using TiN and (Al, Ti)N coated tools, in order to develop water-soluble cutting fluids which have more superior cutting ability than that of water-insoluble cutting oils. Experiments were carried out using a fly tool. As a consequence, the following points were clarified: (1) When using the TiN coated tool, the soluble cutting fluid used in this test prolongs the tool life in comparison with the cutting oils up to a cutting speed of 117 m/min, but at a high cutting speed of 159 m/min, its tool life becomes shorter than that obtained with the cutting oils. (2) With the (Al, Ti)N coated tool, the tool life obtained with the soluble cutting fluid is longer than that obtained with the cutting oils at all cutting speeds tested. (3) From the view points of the tool life, the crater wear and the surface finish, the soluble cutting fluid prepared in this experiment is more effective than the cutting oils when using the (Al, Ti)N coated tool.
