Corundum blasting

Corundum blasting is an abrasive process for surface treatment in which corundum is used as the blasting medium. This process is suitable for removing layers of rust, scale, and paint.

Cutting edge roughness

In the case of cutting tools, cutting edge roughness refers to the non-uniformity along the cutting edge. It is a measure of micro deviations between the nominal and actual geometry of the cutting edge.

Dark energy

Dark energy refers to a form of energy responsible for the expansion of the universe. This energy accounts for about 72% of the total energy contained in the universe. The existence of this hypothetical energy has not yet been experimentally proven.

Degradation behavior

Change in the physical and chemical properties of a material in response to external influences such as temperature and UV radiation. Usually results in degradation and fragmentation processes within the material.

Delivery performance

The delivery performance is defined as the relative obedience of guaranteed lead times against internal or external customers.

Dicing

Dicing is a metal-cutting process that uses peripheral grinding wheels to profile or cut substrates. The blade widths of such grinding blades can be very thin, with values in the two-digit micrometre range, allowing very fine cuts to be produced.

Dicing blade

A standard blade for silicon cutting consists of a metal matrix (nickel) with embedded diamond abrasive grains with a grain size of 4-6 µm. Blade width can typically vary between 35 – 250 µm depending on the application.

Dielectric strength

Dielectric strength reflects the electric field strength at which an electrically insulating material loses insulating properties and conductivity increases sharply. Due to damage to the material, this is an irreversible process.

ECOPROFIT

ECOPROFIT is a program recognized throughout Europe that helps companies to protect the environment and reduce costs at the same time. It combines sustainability (ecology) and economic efficiency (profit). ECOPROFIT Hannover is a joint project of the City and the region of Hannover and the local companies.

Energy Harvesting

Harvesting small amounts of electrical current from the environment (for example, from temperature differences or vibrations).
