CBN grade for turning hardened steel<\/span><\/strong><\/h2>\n

New coated CBN grades for advanced turning methods of hardened steels<\/strong><\/span><\/h2>\n

BC8210 - For continuous and slightly interrupted cutting .Exceptional tool life in high speed machining.<\/span><\/strong><\/p>\n

The BC8210 exhibits excellent resistance to scoring, side surface wear and cratering, thus providing a stable machining process under high-speed cutting conditions.<\/p>\n

Coated PcBN grade for turning hardened steels in high speed machining applications<\/p>\n

Geometries<\/strong>: CNGA, DNGA, CCGW, DCGW,<\/p>\n

Features<\/strong>: For continuous and slightly interrupted cutting, gold plated for easy wear detection<\/p>\n

Advantage<\/strong>: High speed machining with exceptional tool life.<\/p>\n

BC8220 for General Applications<\/strong><\/p>\n

NEW PVD COATING WITH AN IDEAL BALANCE BETWEEN WEAR RESISTANCE AND CHIP RESISTANCE <\/span><\/strong><\/span><\/h4>\n

Achieves impressive tool life over a wide range of cutting conditions.<\/span><\/strong><\/span><\/h4>\n

BC8220 uses a new, specially developed, super multi-layer PVD coating. The high resistance to both abrasion and chipping is achieved thanks to the significantly improved adhesion between the substrate and the coating. Combined with the easy identification of the cutting edges used by the gold TiN surface layer, BC8220 provides high performance and reliability in a wide range of machining applications on hardened steels.<\/span><\/strong><\/span><\/p>\n

Extremely suitable for a wide range of applications, from continuous to heavy intermittent cutting. It also has excellent wear resistance against cratering and breakage thanks to the new PcBN base material, and together with the new coating, the tool life is significantly extended.<\/p>\n

\u00a0Features<\/strong>:Optimized substrate technology with ultramicroparticle binder. The ultramicroparticle binder improves the performance of the most linear cracks to avoid sudden cracking.By increasing the heat resistance of the binder, the wear resistance is increased.<\/p>\n

Field of application<\/strong><\/p>\n

For turning hardened steel, coated CBN inserts are the 1st recommended grade as they have a higher wear resistance than uncoated CBN inserts.<\/p>\n

However, when cutting where a high load is applied to the cutting edge the coated layer tends to peel off and chipping is likely to occur.<\/p>\n

Therefore, in the following three cases, the use of uncoated classes is recommended: MB8200 Series - UNCOVERED PCBN FLOATING STONES<\/strong><\/p>\n

Severely interrupted cutting :<\/strong> Chips and fractures are likely to occur due to intermittent impacts on the cutting edge.<\/p>\n

The hardness of the workpiece is low :<\/strong> The working material itself does not have enough rigidity, which causes vibrations during cutting. Chipping and chipping are likely to occur due to intermittent impacts.<\/p>\n

Cutting with a feed rate or depth of cut of 0.1 mm or less :<\/strong> As the cutting takes place in the R zone of the corner, the load becomes high and chipping and fractures are likely to occur.<\/p>\n

MB8210 - <\/strong> Provides stable machining in continuous and light intermittent cutting of low hardness applications.<\/p>\n

MB8220 -<\/strong>Shows excellent cutting performance in medium interrupted machining.<\/p>\n

The new breaker BL<\/strong> provides good chip control at medium to light cutting depths.
\nA diverse range of chipbreaking tools is available for a wide range of applications.<\/p>\n

Conventional breaker types have a vibration problem when machining long and small diameter workpieces, and their range was not sufficient to meet user requirements. Consequently, a new breaker geometry was needed,a to be developed and extended to T- and V-shaped inserts.<\/p>\n

In response to these problems and demands, breaker BL<\/strong> was developed as a breaker for light - medium cutting depths.<\/p>\n

Low cutting resistance edge design suppresses vibration and chatter.<\/p>\n
