Ceramic Cutting Tool Inserts

Running an interrupted cut with ceramics keyway hex stock or milling you need to run faster.

Ceramic cutting tool inserts.

Its use behavior greatly influences the key machining parameters tool life cutting speed and surface quality. Over the years we have developed a full line of ceramic silicon nitride whisker ceramic and carbide inserts as well as state of the art tool coatings. Totally backwards with ceramics. The spirit of technological innovation spawned the technical ceramics division which began manufacturing ceramic cutting tool inserts in the late 1950 s.

Bosch s products and services from ger. Ssangyong materials 15th anniversary o. Without cl figure 1 a these laths cannot be detected except by lengthy point to point x ray microanalysis. All of the grades show superior high temperature hardness heat resistance and chemical stability.

Ntk s premium ceramic grades ensure the user higher productivity. 1 24 of 273 results for industrial scientific. If you chip a carbide insert you slow down. You chip a ceramic insert you speed it up.

This chart shows the relative strengths of various insert shapes. In figure 1 the microstructure of an al 2 o 3 zro 2 ceramic cutting tool insert is revealed to contain 1 µm zro 2 particles light imaging α al 2 o 3 mid gray and 5 10 µm laths of an impurity phase dark imaging. Whilst cbn has a better tool life the cost per edge of a ceramic insert is a fraction of that of cbn approx one twentieth whilst feed rates chip thickness around 0 1mm and cutting speeds range between 50 200m min are not significantly higher. But the tool tip generally carries much of the stress.

Robert s son dave started with romay in 1981 taking over operations in august of 1996. It starts with round on the outside edge being strongest and moves to 35 which is the weakest. Ntk offers many types of ceramic cutting tool materials silicon nitride based alumina based and whisker based in a variety of geometries to meet customer demands. Cutting with reinforced ceramic inserts put a strain on the tool holder and machine.

Ntk is driven by a spirit to expand on the expertise accumulated through years of research and development to manufacture the highest quality products to propel manufacturing markets. His specialty was cutting tool inserts in particular ceramics.
