Since the late 1980s, turning replace grinding with a hard case has a lot of records. Such as a single-piece low cost, process flexibility and environmental protection advantages often used to set forth the reasons for hard-turning. Hard turning continuously at encouraging double-digit growth. In most of the "world-class" manufacturing organization, hard turning has been accepted and implemented in such a form or another.

As an accepted machining technology, it is desirable progress made hard turning process is consistent with all other processing. To remain competitive, reduce the total cost of each part of the pressure constantly applied to the production. So now is the high productivity machining tool pcbn driving force of development.

This article looks at opportunities such as plunging and wiper technology, and efficient tool concept and reveals both the concept. By using the actual processing cases and surface roughness, cycle time, more accuracy, highlighting the practical ability of these different processing concept.

Hard turning is an accepted process finishing hardened workpiece materials. Compared with other processing techniques, it has a flexible, efficient and good economy. Since it has been published, along with the machine manufacturer to assist, improve pcbn new grades of development and tool manufacturing process, hard turning continue to receive significant performance increase.
