Turning with Diamond and CBN

High precision turning

Nowadays, turning with ultra-hard cutting materials – diamond and CBN – has become an indispensable part of production. Especially in series and high-volume production processes, LACH Diamond and CBN turning tools stand for:

Maximum tool lives with highest possible workpiece quality
Cost-optimized processes due to productivity increases

Satisfied customers

“We have been using LACH diamond tipped inserts and end mills for over 12 years. Lach Diamond tooling is always of the highest quality, order after order.  So much in fact, we have been able to set up entire processes around their tooling which has increased production and efficiencies substantially. Processes that we were unable to accomplish without Lach Diamond tools. We regularly see upwards of 50x tool life increase over standard carbide tooling.” 
Bryan Tyler, Mersen USA

Diamond and CBN meet the high demands for high-precise and efficiency-oriented production.

Diamond- and CBN-tipped turning tools or cutting inserts allow maximum cutting and feed speeds together with surface qualities reaching even ranges of the grinding technology (0,1 µm). Cost- and time-consuming process steps are significantly reduced or even completely avoided as e.g. in case of hard turning (instead of grinding).

Without LACH DIAMOND the use of super-hard cutting materials would not have been possible. So, around 40 years ago, LACH DIAMANT, LACH DIAMOND’s German counterpart, was the first company in the world to use the spark erosion process in order to „form“ the man-made diamond – the polycrystalline diamond (PCD) – for the use in the tool sector – which had been impossible until then – and thus revolutionized all industry sectors. The efficient mass production in several industries like e.g. laminate flooring in the wood and plastic processing sector as well as later also in the automotive industry was born.

Since then, the application possibilities and properties of diamond and CBN turning tools have constantly been multiplied and perfected. As a consequence our customers are able to ensure process safety, quality and tool life even in case of high demanding conditions and difficult to machine materials.

To ensure that our partners are always one step ahead within their market, LACH DIAMOND offers highly competitive tools, e.g. the “full chip control” with the PCD-chipbreaker programme »IC-plus« world’s best (pat.).

“Turning instead of grinding”

Turning of hardened steels with newly developed CBN cutting inserts.

The demand of the automotive and supply industries for a durable cutting material for turning hardened steels has been met with the development of new CBN cutting materials like the types B610 and B600 used by LACH DIAMANT – and with highest surface qualities of e.g. Ra 0,1 µm.
