In recent years, hard car parts 'unknown' surface integrity also cause some reluctance to hard turning as critical surface finishing. However, the recent development of tool technology is likely to challenge these ideas. In particular, the new overall pcbn blade and insert new car technology has been proven and traditional grinding process can be comparable or better accuracy.

    In one of the recent development of high cbn100 Xiangshan and cbn300 so hard car to finish high economical choice overall pcbn blade. Especially for machining hardened steel blade cbn100 and cbn300 overall provision and traditional carbide tipped blade or the same number of cutting edges, plus a long cutting edge. Due to their overall structure, a new blade to provide a significantly higher abrasion resistance and lower cost per blade. In a study of the high mountains of the overall blade with the other five different tool manufacturers tipped blade comparison, each edge cost savings from 25% to 208% range.

    As an added advantage, cbn100 and cbn300 also makes it possible to plug the car. Interpolated using the entire car is a part of the cutting edge of the cutting edge or to create a highly productive form of hard turning right angle cutting. This relatively new technology has been proven to reduce the processing time up to 90%, the surface integrity of the production of the same parts with those grinding.
