Cermet Indexable Inserts

Cermet is a composite material that combines ceramic and metallic materials. Ceramic Inserts provide long tool life and excellent surface finish.

Meanwhile, with excellent chemical stability, Ceramic Turning Inserts has the advantage of high wear resistance, and their service life is 1-3 times that of traditional carbide CNC Tools.


Cermets, especially Ti(C,N)-based Cermet Turning Insert, exhibit high chemical stability against the material being processed, resulting in the weakness of processing friction and the decrease of contact temperature, thus effectively preventing the interdiffusion of atoms between the tool and the work piece material and significantly improving the anti-adhesion wear performance.
Ti(C,N)-based Cermet Cutting Tools exhibit excellent red hardness and excellent resistance to crescent crater wear under high-speed cutting conditions.

What Is Cermet?

Cermet is made of metal and ceramic materials. It has both the advantages of metal and the characteristics of ceramics. Because of its high toughness, high hardness, and high oxidation resistance, it is highly regarded in rockets and high-speed aircraft.

The metal raw materials most commonly used to make cermets are iron, nickel, cobalt, etc. The most commonly used ceramic raw materials are oxides, silicides, borides, carbides, and nitrides. The production of cermet is also relatively simple. The firing method is the same as that of ceramics, except that the metal powder is mixed into the ceramic soil to produce different shapes according to requirements.

What Is the Difference Between Ceramic Blades and Cermet Blades?

Ceramics have higher hardness than cermets, and cermets have better toughness than ceramics. The ceramic blade contains only ceramics, and the cermets are mixed with metal and ceramics. The cermets are for steel, cast iron, stainless steel finishing, semi-finishing

Ceramic blades are new-type blades made of high-tech nanotechnology. The sharpness is more than ten times that of steel blades. Therefore, ceramic blades have the characteristics of high hardness, high density, high-temperature resistance, magnetization resistance, and oxidation resistance.

The ceramic knife is developed using high-precision ceramic high voltage, so it is called a ceramic knife. Ceramic knives are known as "noble knives". As a product of modern high technology, they have advantages incomparable with traditional metal knives; they use high-tech nano-zirconia as raw materials, so ceramic knives are also called "zirconium gem knives". You can see it.

What Grinding Wheel Is Better for Cermet Blades?

First, the material of the abrasive must be diamond. For non-metallic hard and brittle materials, diamond is just against it.

Secondly, the cermet blade you mentioned may be a toughened cutting ceramic material. Generally speaking, resin diamond is good at grinding hard and brittle materials, but hard and tough materials tend to heat up during grinding. Efficiency and wheel life are not good,

Comprehensive consideration should be given to ceramic bonded diamond wheels, ceramic heat resistance, wheel life is good, and can ensure that the diamond is held under high cutting conditions, the high grinding efficiency is commonly used SDC wheels.

At present, most ceramic knives on the market are processed with a nano material "zirconia". The zirconia + alumina powder was pressed into a mold blank with a weight of 300 tons, and then sintered at 2000 degrees Celsius. After grinding with diamond, it was equipped with a handle to make a finished ceramic knife.
