CERADIA CNF - Abrasive grit synthetic

CNF 3100

Especially distinctive crystalline structure with high impact resistance and thermal strength as well as a uniform particle shape. It is able to absorb high mechanical stress in metal bond tools. Typical applications are in glass edge processing (automotive),

CNF 3090

Distinctive crystalline structure of a slightly lower strength than CMG 100. CMG 90 is mainly used in metal bond tools and offers a particularly high stability even of high temperatures. Applications are in the automotive industry (glass processing, engine blocks),

CNF 3080

High-quality, crystalline abrasive grit with a small amount of inclusions. The crystal shape is little more irregular and due to the inclusions less thermally resistant. Good strength. Suitable for glass processing, décor grinding, facet grinding and drilling of crystal glass; metal grinding. Used in metal bond applications.

CNF 3070

This diamond grit is suitable for processing automotive glass and décor glass and still offers a high thermal and mechanical stress resistance. It is also suitable for grinding wheels applied in areas with lower stress but bigger wheel widths and contact lengths.

CNF 3060

Due to the composition of a variety of differently structured grain shapes CMG 60 is suitable for a broad range of metal bond tool applications in the glass and ceramic industry. The composition makes the grit fast cutting. The amount of evenly spread crystals ensures the stability of the tool.

CNF 3050

The structure of this grit makes it suitable for general grinding tasks with only little cutting stress. The grit shape is rather irregular with an emphasis on fast cutting. CMG 50 is also found in glass processing.

CNF 3040

A rather irregular diamond grit used for free-cutting purposes. Areas of application are: the dental industry, the grinding of steel and carbide combinations and the cutting of glass and quartz.

The coating can protect the diamond from erosion and at the same time expands the area of action of the diamond grit. This way the energy consumption is reduced and the cutting ability is increased.

Cr

Chrome Cr 1 %

The retention of Chrome can be improved with CR3C2 which is released during the sintering process. Chrome has good wetting properties and affinity to diamonds, it is used in metal bond systems.

Cu

Copper Cu 30 %, 50 %, 56 %

The copper coating extends the lifetime of the tools. It improves the retention of the diamond and expands the heat distribution. The coating is suitable for soft bonds.

Co

Cobalt Co 30 %, 50 %, 56 %

The cobalt coating improves the retention of the diamond and increases the oxidation temperature of the diamond and the sintering temperature.

Nickel

Nickel

Nickel Ni 30 %, 50 %, 56 %

The coating can protect the diamond from erosion and at the same time expands the area of action of the diamond grit. This way the energy consumption is reduced and the cutting ability is increased. The surface of this kind of coating is smooth. The lifetime of the tools can be extended due to the extreme retention between the nickel layer and the surrounding bond.

CNi

CNi

Chemical Nickel CNi 30 %, 50 %, 56 %

The energy consumption is reduced, since the retention between diamond and bond, as well as the lifetime are improved. Due to the very rough structure of the coating the specific surface is enlarged.

TiNiS

TiNiS

Nickel Spikey TiNiS 56 %, 70 %

This coating extends the lifetime of the tool, improves the sharpness and increases the specific surface and the retention between matrix and diamond. It is predominantly used in soft bond at reduced sintering temperatures.

Si

Si

Silicon Si 2 %

The chemical coating improves the retention between the bond and the diamond. Silicon coatings increase the wear resistance, the thermal resilience and prevent the ability to disintegrate iron.

Ti

Titanium Ti 2 %

During the tool production the bubble free titanium coating prevents the erosion of iron, chrome and tungsten at high temperatures. It prevents the bursting of the grit, extends the lifetime of the tool and improves the preservation of the bond and the diamond.

TiC

TiC

Titanium Carbide TiC 1,5 %

The contact area for sintering increases and so the coating level for titanium carbide is higher. The industrial use of the titanium carbide coated grit is comparable to the titanium one.
