Discussing on machining the guide roller of complex nickel ahoy by the lathe with PCBN tool;

Rationally choose geometry parameter and cutting data of PCBN tool, in order to raise processed quality.

The characteristics,latest structural design and application of PCBN tool are introduced.

Comparison of wear during dry and wet cutting of quenched steel with PCBN cutting tool

The applicable machining materials of PCBN cutting tools and rational selection methods for geometry parameters, cutting data and insert brands of PCBN cutting tools are introduced.

Based on the experiment used the PCBN cutter dry-cutting hardened GCr15 bearing steel, the wear curve of the tool flank is obtained and the wear characteristics and mechanism of PCBN tool are investigated through observing the wear types of the tool with scanning electron microscope.

By analyzing the machining features of rollers for rolling sealing strips used in car window, a NC machining process to hard cut the complex shape of rollers by using PCBN cutter is presented.

The cutting experiments were carried out to investigate the cutting performances including the cutting forces, chip morphology and cutter's wear characteristic during precisely turning the hardened GCr15 bearing steel with the PCBN cutter.

Study on interrupted turning of hardened steels with PCBN tools

a fully coupled thermal-stress finite element analysis,which considers the temperature effect on material physical and mechanical property and the change of flow stress that depends on the plastic strain, strain rate and temperature,was developed in this study to simulate the flow chip and saw-tooth chip formation when high speed hard cutting hardened steel GCrl5 with PCBN tools.

In order to manage the multimedia information of PCBN cutting tools synthetically,this database is developed on the platform of Visual Basic, at the same time, it also uses the connection technology of Visual Basic and the management system of Microsoft SQL Server 2000.

In order to inquire about and make management of various information of PCBN cutting tools, a consultation and management multimedia database system of PCBN cutting tools is presented.

By analysis the main technology characteristics of the module, The processing methods of high speed boring positioning hole was discussed, with high hardness、 thermal rigid and chemical stability of PCBN cutting tools on the vertical machine center.
