Saw grit synthetic

CERAGRIT - Saw grit synthetic

For sintering temperatures up to 1,000 ° C and higher

Diamonds are generally differentiated into 2 categories: natural and synthetic. The natural diamond is the hardest known naturally occurring mineral. Both types are used as superabrasive and cutting material in the respective industries.

Since it is a material with the largest effective heat conductivity, it is also used in other sectors e.g. in the electronics industry as a heat sink or as a frequency wave filter in the communications industry.

We can meet all the requirements of the tool application, since our CERAGRIT saw grit synthetic is of consistent quality.

  • These crystals are very regularly formed with hardly inclusions and no cube shapes; the heat and impact resistance is very high.
  • Toughness: very high
  • Application: Asphalt, granite with large diameter blades, core drilling of reinforced hard concrete, wall sawing. Sawing of hard concrete with or without reinforcement and a high rate of most abrasive aggregates.

CNF 3080

  • Crystals: very clear in color, small inclusions, strong uniform shape, sometimes not fully developed
  • Application: core drilling, sawing of concrete materials in wall and wire saws, granite

    Thermal load: lower than CNF3090

CNF 3070

  • Crystals: still of uniform structure, partly fully formed; resistance: high
  • Application: natural stone industry (e.g. marble), generally suitable at low mechanical loads, and in grinding wheels with medium load

CNF 3060

  • Crystals: relatively regular in shape
  • Toughness: medium
  • Application: grinding wheels/saws at lower loads.

    Natural stones (marble), hand held tools for professional use, free-cutting inserts (e.g. socket core drill in concrete)

CNF 3050

  • Crystals: irregular shape
  • Toughness: medium, reduced after high temperature exposure
  • Application: in free-cutting socket core drills in concrete, grinding/polishing of granite and marble, DIY range

CNF 3040

  • Crystals: irregular structure, medium toughness, sharp and free-cutting
  • Toughness: little less than CNF3050, reduced after high temperature exposure
  • Application: low load machining in hand held tools (e.g. floor grinding), DIY range

CNF 3030

  • Crystals: irregular, open surface
  • Toughness: low
  • Application: for low load processing (e.g. floor grinding)

CNF 3020

  • Crystals: irregular, splintery, mostly irregular open surface
  • Toughness: low, between CNF 3010 and 3030
  • Application: for low load processing (e.g. floor grinding)

CNF 3010

  • Crystals: extremely splintery, only irregular open surface
  • Toughness: very low
  • Application: only for very slight processing

Coating types with diamond grain

Depending on the type of coating, it supports the holding forces between the grain and the bond, and / or the thermal conductivity and the reaction with the metal bond. In case of the right combination with the bond, the service life of the tools can be extended or the process properties can be optimized.

Cr

Chrome Cr 1 %

Chrome is used in metal bond systems, has good wetting properties and affinity to diamonds. During the sintering process CR3C2 is released so the retention can be improved.

Cu

Copper Cu 30 %, 50 %, 56 %

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

Co

Cobalt Co 30 %, 50 %, 56 %

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

Nickel

Nickel Ni 30 %, 50 %, 56 %

Due to the extreme retention between the nickel layer and the surrounding bond, the lifetime of the tools can be extended. 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.

CNi

Chemical Nickel CNi 30 %, 50 %, 56 %

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

TiNiS

Nickel Spikey TiNiS 56 %, 70 %

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

Si

Silicon Si 2 %

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

Ti

Titanium Ti 2 %

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

TiC

Titanium Carbide TiC 1,5 %

The use of the titanium carbide coated grit and the titanium one is similar. The contact area for sintering increases since the coating level for titanium carbide is higher.
