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

      In one recent development is the Xiangshan high CBN100 and CBN300 so hard the car finishing economical high selected solid PCBN inserts. Special offers and traditional or carbide tipped blade cutting edge for the same number of overall machining hardened steel blade CBN100 and CBN300, plus the length of the cutting edge. Back due to their overall structure, the new Blade provides significantly higher wear resistance and lower cost per edge. In a study Seco 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. Interpolation using the entire car is a part of the cutting edge or cutting edge to create high productivity in the form of hard turning at right angles to the cutting. This relatively new technology has been proven to reduce the processing time by up to 90%, the surface integrity of parts produced with those same grinding.
