Tools made from diamond, the hardest substance in the world, and from cubic boron nitride (CBN) with hardness akin to diamond are used in various industries around the world.
Recently, technological innovation has further accelerated, with the increasing demand for diamond/CBN tools. We are developing tools to meet market needs while conducting research and development, anticipating the future.
In the diamond products business, we are committed to developing new products and new technologies with the themes: "high efficiency processing," "high-performance processing at nano level" and "environmentally friendly processing."
|Example of applications||Improved efficiency, longer life and higher accuracy in finishing holes of sintered alloy and cast iron.|
We are developing diamond wheels for grinding various semiconductor materials.
Making full use of the know-how of semiconductor material processing we have cultivated over the years, we have realized a dedicated design tailored to the characteristics of each material and processing needs.
|Wafer size||4 in.
Tools made of ultra-hard materials are mainly used for hole finishing of sintered alloy or cast iron, which are widely used in the automobile field; nevertheless, higher efficiency and longer service life are still required. To meet these needs, we have developed tools using CBN material suitable for machining sintered alloy and cast iron.
We succeeded in developing a CBN reamer that can achieve dramatically high efficiency, long life and high precision compared with cemented carbide tools.
