Journal of Superhard Materials, 2009
The results of the comprehensive studies of a highly efficient method of finishing, the so-called hard “skiving” turning, are discussed. Special features of the oblique cutting with a tool equipped with cBN-based polycrystalline superhard materials are shown, the regularities of the surface roughness formation and surface layer hardening in machining ...

Hard turning is a turning operation performed on hard materials (hardness more than 45 HRC) in order to reach surface roughness close to that obtained in grinding. The development of this technology was accompanied by the development of new cutting materials such as cutting ceramics, cubic boron nitride and polycrystalline diamond.

Journal of Materials Processing Technology, 2008
Nowadays, hard turning is frequently used to replace grinding. The economic benefits of hard turning are obvious but for achievable accuracy the situation is somewhat ambiguous. Although machine tool factories offer lathes with the same accuracy as grinding machines in some cases problems may arise in keeping the prescribed geometrical accuracy ...

FORCES AND TEMPERATURES IN HARD TURNING
Machining Science and Technology, 2006In precision machining, due to the recent developments in cutting tools, machine tool structural rigidity and improved CNC controllers, hard turning is an emerging process as an alternative to some of the grinding processes by providing reductions in costs and cycle-times. In industrial environments, hard turning is established for geometry features of

Machined surface temperature in hard turning
International Journal of Machine Tools and Manufacture, 2017Abstract Machined surface temperature is critical in turning of hardened steels because high surface temperature can lead to the formation of the white layer, which may have negative impacts on the steel fatigue life. This paper presents two experimental methods to measure machined surface temperatures in hard turning.

Chip Formation When Hard Turning Steel
Manufacturing Science and Engineering: Volume 2, 1997Abstract Hard turning of machine parts is a production process that holds considerable promise for the future since it is an effective means of increasing productivity. Instead of machining a product in the soft state, hardening the part by heat treatment, and then providing the required finish and dimensional accuracy by grinding the ...

Surface Integrity in Hard Turning
2003Highly-stressed steel components, e.g. gears and bearing parts, are appropriate applications for hard turning. Therefore the process effects on significant engineering properties of work materials have to be carefully analyzed. Roughness, residual stresses and white layers as parts of surface integrity, are function of the machining parameters and of ...

Hard Turning with PCBN Tooling
1999Material removal, at economic rates, from hardened workpieces has always presented a challenge and, until quite recently, abrasive machining processes were the only option for hard-facings. However, cutting tools based on polycrystalline cubic boron nitride (PCBN) have opened up the possibility of turning and milling as attractive alternatives for ...
