In recent years, hard car parts 'unknown' surface integrity also cause some reluctance to hard turning as a key surface finishing. However, the recent development of the tool technology are likely to challenge these ideas. In particular, the new overall pcbn plunging inserts and new 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 economical car finishing high selectivity of the overall pcbn blade. Especially for machining hardened steel blade cbn100 and cbn300 overall offer and traditional carbide blade inserts or the same number of cutting edges, plus the length of the cutting edge. Due to their overall structure, provides new blade significantly higher abrasion resistance and lower cost per blade. 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.
