Ceramic Cutting Tool Inserts

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.

Ceramic cutting tool inserts.

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. You chip a ceramic insert you speed it up. 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. There are so many different machining tasks that can be efficiently and economically solved with ceramtec s range of cutting materials and indexable inserts for workpieces made of cast iron steel hardened steel and special materials.

Bosch s products and services from ger. Cutting with reinforced ceramic inserts put a strain on the tool holder and machine. His specialty was cutting tool inserts in particular ceramics. With carbide you can run a higher sfm turning than milling interrupted cut and all.

Running an interrupted cut with ceramics keyway hex stock or milling you need to run faster. Ssangyong materials 15th anniversary o. If you chip a carbide insert you slow down. 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.

This chart shows the relative strengths of various insert shapes. But the tool tip generally carries much of the stress. Indexable inserts price and other details may vary based on size and color kyocera tpg 18151t00320 pt600m grade ceramic 60 degree triangle positive rake angle neutral turning insert for continuous in hard material 10 pcs. 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.

Ntk s premium ceramic grades ensure the user higher productivity. All of the grades show superior high temperature hardness heat resistance and chemical stability. It starts with round on the outside edge being strongest and moves to 35 which is the weakest. The spirit of technological innovation spawned the technical ceramics division which began manufacturing ceramic cutting tool inserts in the late 1950 s.

Without cl figure 1 a these laths cannot be detected except by lengthy point to point x ray microanalysis. Totally backwards with ceramics.
