This article illustrates the production method and mechanical & physical properties of polycrystal cubic boron nitride (PCBN) cutting tool material. As shown by the turning machining of hardened steel, cold-hardened cast iron and composite materials, PCBN cutting tool is superior in cutting performance to cemented carbide and ceramics cutting tools. In recent years, with great improvement in production process and overall mechanical properties of PCBN cutting tool material, it can effectively make rough machining of ferrous metal. This article contributes to the popularization and application of this cutting tool.

Cubic boron nitride is becoming an alternative cutting tool material for machining under demanding conditions, displaying superior wear performance and machined parts with higher quality. The current need to reduce the cobalt content in these tools led to this study and focused on alternative binder materials for cubic boron nitride cutting tools. This work addresses several nickel–cobalt-based materials, regarding their microstructure, mechanical (hardness and shear strength), and tribological performance. The best results were attained when adding tungsten carbide to nickel–cobalt, once nickel–cobalt–tungsten carbide was found to display the higher mechanical properties, together with the higher wear resistance.

The article considers the problems of forecasting the performance of cutting tools equipped with replaceable ceramic cutting bits. It is proposed to forecast the operability of ceramic tools on the ground of dependence between its performance characteristics and the microstructural parameters of the tool material. It is proposed to determine the parameters of ceramic bits microstructure by a nondestructive testing methods based on measuring the specific electrical resistance of ceramic materials. As a result of the study we have undertaken, a relationship was detected between the performance and specific electrical resistance of ceramic cutting tools.

Ti-6Al-4V components are the most widely used titanium alloy products not only in the aerospace industry, but also for bio-medical applications. The machine-ability of titanium alloys is impaired by their high temperature chemical reactivity, low thermal conductivity and low modulus of elasticity. Polycrystalline cubic boron nitride represents a substitute tool material for turning titanium alloys due to its high hardness, wear resistance, thermal stability and hot red hardness. For determination of suitable cutting parameters in dry turning Ti-6AL-4V alloy by Polycrystalline cubic boron nitride cutting tools, the samples, 300mm in length and 100mm in diameter, were dry machined in a lathe. The turning suitable parameters, such as cutting speed, feed rate and cut depth were determined according to workpieces surface roughness and tools flank wear based on orthogonal experimental design. The experiment showed that the cutting speed in the range of 160~180 m/min, the feed rate is 0.15 mm/rev and the depth of cut is 0.20mm, ideal workpiece surface roughness and little cutting tools flank wear can be obtained.

Three different cutting tools (ceramics CC6050, cubic boron nitride CB7025, carbide GC2025) were used for dry cutting of 3 groups of ADI which were heat-treated separately under different quenching temperatures. With the unified cutting parameters, the wear of tool flank of each cutter was studied and the main influencing factors of the wear were analyzed. Results showed that when the cutting parameters ap =0.2mm, f =0.16mm/r, vc =108m/min and the cutting tool was determined, the higher the quenching temperature was the lower the hardness of the test bars were and the tool flank wear was less; When the quenching temperature was determined, the more the produced BUE (build up edge) of the cutting tool was the less the tool flank wear was.
