HISTORY

Ceramic cutting tools revolutionized the automotive manufacturing industry

In 1958 NTK started selling ceramic tools.
At the time, it was common to machine cast iron brake discs using carbide tools.
Automobile production increased which led to the demand for an increased number of parts to be manufactured. Ceramic cutting tools answered the demands with efficient high-speed machining conditions.
Our products have been a great support to the Japanese automotive parts manufacturers.
NTK is proud to support the entire global manufacturing industry today and into the future.

The evolution of Information Technology (IT) has expanded the use of Automatic CNC lathes (Swiss CNC lathes)

In 1992 NTK began selling Swiss automatic CNC lathe tooling.
The expansion of personal computers and automated equipment lead to an increase in demand for precision parts. To meet these needs NTK lead the industry in launching a complete Swiss tooling line including replaceable inserts.
The carbide inserts brought a reduction in edge grinding process time, longer tool life and more consistent workpiece dimensions.
As a result, an efficiency to the production of precision parts was realized. NTK is proud to provide its support to this industry.

Birth of BIDEMICS, an innovative new tool material positively impacting the ever-expanding aerospace market.

BIDEMICS sales launched in 2015, for machining heat resistant alloy parts.
To meet the increasing demand for aircrafts, engine parts manufacturers need to look for effective ways to improve their productivity.
Aircraft engine parts made from heat resistant alloys are extremely difficult to machine. Even mainstream whisker ceramic inserts needed to be replaced every 5 minutes.
NTK met the challenge and developed BIDEMICS to achieve double the tool life of whisker ceramic and providing superior performance with high-speed machining of heat resistant alloys.
NTK is proud to support the global aerospace manufacturing industry today and into the future.

ABOUT NTK

Today's NTK CUTTING TOOLS

Today, NTK's cutting tools are delivered to customers around the world from facilities located in 11 countries.
Since sales of ceramic tools began in 1958, NTK has expanded its product range to include products that contribute to highly efficient, high-precision machining, such as BIDEMICS for machining heat-resistant alloys and Swiss Tooling for CNC automatic lathes.

Support

A sales network and follow-up system to ensure that NTK products can be used with confidence at machining sites around the world.
Our sales, engineering, manufacturing, and quality control departments work together to provide products and services that are truly needed by the people who actually use cutting tools.

Development

Our corporate message is "Beyond Ceramics, Exceeding Imagination," and NTK's cutting tools aim to embody this message.
We will continue to develop unprecedented materials and products by utilizing the experience and technology we have developed in ceramic tools and Swiss tooling.
Please accept NTK's challenges, including "BIDEMICS Type S" (under development)", which aims to cut steel at a cutting speed of 1000m/min.

Quality control

Since cutting tools are also a manufactured product, some variation occurs.
We take pride in delivering the highest quality inserts by minimizing variations so products conform to strict specifications.
