Summary

Slide 1
Technology innovation

Through the chemical gas phase separation, so-called CVD process (Chemical Vapor Deposition), we can coat our blades, tools, bullets and scalpels with diamond. The plasma sharpening process can significantly increase the sharpness and durability (long life).

Slide 2
Why diamond

Diamond has a unique combination of outstanding material properties. It is extremely hard, yet light, wear-resistant, chemically inert, electrically non-conductive and has a particularly low coefficient of friction. This makes diamond ideal for mechanical applications.

Plasma sharpened diamond

The production is based on two technologies developed by us:
❯ First, a nano crystalline diamond coating is applied to a carrier made of hard metal.
❯ This ultra thin layer of pure diamond is then applied polished using a plasma sharpening process.

Technology made in Germany

GFD develops and produces diamond-based products and has established itself as the world’s leading supplier of diamond microtechnology. Our products impress with their outstanding properties in the fields of medical technology, pharmaceuticals, material processing and semiconductor technology.

All our products are manufactured in Germany. Using the chemical vapor deposition (CVD) process, we can coat our blades, tools, balls and scalpels with diamond on site. The big advantage here is that we can coat components up to an edge length of 500 mm ourselves.

Diamaze PSD (Plasma Sharpened Diamond) cutting edges consist of a carbide cutting edge coated with diamond. The thickness of the diamond layer can vary between 5-25 µm. Due to the diamond coating, the service life of the blades can generally be significantly increased.

The plasma sharpening process developed at GFD now allows the sharpness of the cutting edge to be significantly increased retrospectively. This makes it possible to achieve a significant increase in service life in combination with optimized sharpness.

Innovation ➜ plasma-sharpened diamond (PSD)

Why diamond

Diamond has a unique combination of outstanding material properties. It is extremely hard, yet light, wear-resistant, chemically inert, electrically non-conductive and has a particularly low coefficient of friction. This makes diamond ideal for the most demanding mechanical applications.

How plasma-sharpened diamond is created

The production of plasma-sharpened diamond is based on two innovative processes:

  1. First, a nanocrystalline diamond coating is applied to a carbide substrate.
  2. This ultra-thin layer of pure diamond is then polished in a plasma sharpening process.

The advantages

  • Extremely high sharpness because diamond-coated and plasma-sharpened.
  • Significantly longer service life and hardly any change in sharpness over the service life.
  • Lower long-term costs due to longer service life and lower maintenance requirements.
  • Reduced machine downtimes and set-up costs.
  • Increased efficiency and cost savings due to high yield.
