Wear Rate of CBN Cutting Tool in Hard Turning of 100Cr6 Bearing Steel

Abstract:

The examination of wear and tool life of CBN cutting tools which are used for hard turning is a emphasized research theme, since the significant proportion of cost of machining associated with cutting tool. In this article we examined the wear of low CBN content cutting tool in case of hard turning of 100Cr6 bearing steel (HRC=62±2). The experiments were carried out with constant depth of cut and feed rate at three different cutting speeds. The flank wear of CBN inserts were measured after predetermined number of passes. The measured flank wear values were described as a function of cutting time and the calculated wear rate as a function of flank wear.The average wear rate were shown at three different cutting speeds.
