Q&A: Diamond/ CBN tools

What are the characteristics of diamond and CBN?
Diamond is the hardest among all substances except in high temperature range, and with high thermal conductivity. CBN (cubic boron nitride) has similar characteristics to diamond.
What are diamond/ CBN tools?
They are tools used to machine various materials making full use of the characteristics such as high hardness and high thermal conductivity.
What kind of tools do you have?
We have tools for scraping and polishing materials, cutting and drilling tools, and wire drawing tools.
Where are the tools used?
The tools are used in various industries including automobiles/machine parts, electronic parts, and glass/ceramic parts.
What is grinding?
Grinding is a processing method of rotating a grinding tool holding numerous diamond grains or CBN grains at high speed and grinding the material by pressing the tool against it.
What are the characteristics of diamond/ CBN grinding tools?
By the characteristics of high hardness and high thermal conductivity, they provide high-efficiency machining.
For mass production processing, reduced processing cost can be achieved.
Where are the diamond grinding tools used?
Grinding tools are mainly used for mass production of hard and brittle materials such as electronic parts, and glass and ceramics parts. We offer grinding tool products that demonstrate superior performance in various materials, processing methods and processing machines in our lineup.
Where are the CBN grinding tools used?
The CBN grinding tools are mainly used for mass production of car parts and molds, of ferrous materials and heat-resistant material parts. our line-up offer grinding tools that have superior performance in various materials, processing methods and processing machines in our lineup.
What are truing and dressing?
Truing and dressing are processes, unique to the grinding process, to recover sharpness and shape accuracy of the grinding tool.
We offer products that demonstrate excellent performance in truing and dressing of various grinding tools.
What is cutting?
Cutting is a processing method of pressing a cutting tool holding a single-or multi-edged diamond or CBN against the rotating material.
Where are the diamond cutting tools used?
Diamond cutting tools are mainly used for car parts where nonferrous metal material such as aluminum is used, and high efficiency and high precision machining of optical molds. Our lineup offers cutting tool products that demonstrate excellent performance in various materials, processing methods, and processing machines.
Where are the CBN cutting tools used?
CBN cutting tools are mainly used for mass production of ferrous car parts and machine parts. Our line-up offers cutting tool products that have excellent performance in various materials, processing methods, and processing machines.
What kind of processing are dies (tools) used for?
Dies are used for making the outer diameter of the metal wire smaller and lengthen the wire in the length direction.
Where are the dies used?
Dies are used for drawing copper wires used as motor windings wires and electric wires, aluminum wires used for electronic parts, and stainless steel wires used for screens, etc.
