KNOW-HOW

Production

Cutting materials

Diamond segments are compounded by blending metal powders and synthetic diamonds. The segments are sintered to the desired shape and dimensions by compression molding at high temperature and pressure. The result is a metallic matrix with embedded diamond grains.The amounts and types of metal and diamond components used are formulated specifically for the intended application, i.e. the materials to be processed. The formulation is a key factor for the tooling's cutting performance and wear behavior.
The cutting effect of the diamond segments is provided by the diamond grains which protrude out of the metal matrix. The segment composition is engineered to provide smooth operation and highly effective cutting performance.

Milling and grinding of:

  • Concrete
  • Reinforced concrete
  • Natural stone
  • Artificial stone
  • Deposits / fouling
  • Cast iron
PCD segments are made from a tungsten carbide base material with diamond micropowder on its surface.
A special sinter process with high pressure and temperature is used to transform the loose micropowder into a homogeneous diamond layer. The PCD blanks made in this manner are then cut into individual PCD segments and configured with cutting geometry as required for the intended application.
The cutting effect of PCD segments is provided by a cutting edge which is tailor-designed for the application field at hand. PCD tooling provides aggressive cutting behavior with rapid volume removal.

Milling of:

  • Concrete
  • Natural stone
  • Artificial stone
  • Deposits / fouling
  • CIPP liners
  • PVC
  • Roots
Tungsten carbide granules are recycled material recovered from turning or cutting inserts used in the metalworking industry. The inserts are transformed to granular material by a crushing process providing the required grain size distribution.
Tungsten carbide granulates are available in a broad spectrum of grain sizes ranging from very fine (0.3 – 0.5 mm) to coarse (3.0 – 4.0mm). This provides high flexibility for design of tailor-made tooling for specific applications.
The cutting effect is provided by the tungsten carbide granules protruding from the tooling surface. Grain size and grain spacing can be selected as required to further optimize cutting performance.

Milling and grinding of:

  • CIPP liners
  • PVC
  • Roots
