Micro-fine grain carbide tools wear longer

Micro-fine grain solid carbide miniature tools with new cutting geometry and very small diameters provide a wear resistance in pre-hardened steels close to that of CBN tools.

Hitachi Tool places considerable emphasis on research and development, and it is this company policy that has enabled Hitachi Tool to continuously generate innovative tool solutions, in particular to meet and anticipate the requirements of the tool, die and mould-making industries.

Constantly increasing pressure on time and costs in the field of tool, die and mould-making mean reduced cycle times and more efficient machining processes are essential.

In order to meet these requirements, Hitachi Tool has developed the new range of Epoch Super Hard Ball micro-fine grain solid carbide miniature tools.

In recent times, the materials used in tools and dies and mould-making have become ever harder, making the machining of them that much more difficult.

In addition, the high degree of wear on the tools prevents moulds with peak tolerances from being manufactured easily.

As a result, the focus has been to use CBN tools for harder materials.

However, these can often not be used dependably for long machining times without suffering from breakage.

The newly developed Epoch Super Hard Ball now achieves a reduction in the gap between solid carbide and CBN tools.

The new cutting geometry coupled with our tried-and-tested TH45+ NANO-PVD coatingand the optimised micro-fine grain solid carbide substratenow provide users with a wear resistance close to that of CBN tools.

The back-draft geometry of the cutting edges also ensures steady, dependable machining with even the smallest diameters and with minimised vibration levels.

The closest possible tolerances on the radii and shafts enable highly accurate finishing.

The Epoch Super Hard Ball has a standard tolerance of -0.007mm to +0.003mm on the radius.

The tools have high resistance to weareven with materials over 60HRC (up to 72HRC).

The Epoch Super Hard Ball is available in sizes R 0.05mm to R 1.0mm, which makes it the ideal choice when machining the smallest of workpieces.
