Tool restoration

Using the same high precision CNC grinding machines, which are used in Guhring manufacturing plants, our recovery department is well equipped for recovery standard and special tools made of high speed steel and hard alloys to their original factory quality, condition and performance. Precision restoration provides a longer tool life and often more regrinds per tool, which leads to significant savings in both tooling and machining costs. We can provide factory repair not only for Guhring tools, but also tools from other manufacturers.

Tool coating

Coatings for cutting tools and wear parts for recent decades have been the subject of tremendous technological progress. Thin film coatings, when applied correctly, improve performance and the functionality of the tool and parts. They increase hardness surfaces, reduce the coefficient of friction and thermal conductivity and provide a chemically inert surface. As a manufacturer cutting tools Guhring offers an unrivaled level of knowledge in the field of coating. Guhring was the first who introduced TiN coating for tools in 1980 and remains world leader in the development and application of new coating technologies.

Types of coatings
TiN coating
Max. application temperature: <600 ° C
Color: golden yellow
Structure: single layer
Hardness: 2300 HV0.05
The coating introduced by Guhring back in the early 80s TiN finds application in drilling processes as an inexpensive coating covering a wide range of tools in high speed steel and carbide.
FIRE / nanoFIRE coverage
Max. application temperature: <800 ° C
Color: purple
Structure: multilayer
Hardness: 3300 HV0.05
In addition to titanium and nitrogen, FIRE and nanoFIRE coatings also contain aluminum. These coatings were introduced already at the end of the 90s and represent a further development of TiN coatings. They are characterized by higher hardness and good thermochemical resistance and are suitable for both high speed steel and carbide.
TiAlN coating
Max. application temperature: <800 ° C
Color: purple
Structure: single layer
Hardness: 3300 HV0.05
The TiAlN coating is very well suitable for cutting hard materials. TiAlN coating has similar properties as FIRE and nanoFIRE and Due to its single-layer structure, it is often used in the range of small drills.
Signum Coating
Max. application temperature: <800 ° C
Color: bronze
Structure: multilayer nanocomposite
Hardness: 5500 HV0.05
Signum belongs to the group of so-called nanocomposites. The microstructure is different very small TiAlN nanocrystals, which are incorporated into a glassy, high temperature resistant silicon nitride matrix. This results in high hardness, which makes Signum the first place, especially for the processing of hardened steels and casting materials.
Endurum coating
Max. application temperature: <800 ° C
Color: copper
Structure: multilayer nanocomposite
Hardness: 4000 HV0.05
Endurum, also a coating from the nanocomposite family, it was targeted Designed for machining carbon, free-cutting and magnesium-alloyed steels.
