  • Offer Profile
  • Based in Kaiserslautern, Germany, we have specialized in the development, manufacturing and sale of precision tools equipped with ultra-hard cutting materials such as PCD (polycrystalline diamond), CVD-D (CVD thick film diamond), UltraDiamond (binderless) and CBN (cubic boron nitride). As a leading manufacturer of tools with lasered cutting edges, we offer machining solutions in the areas of turning, milling, grooving, drilling, reaming and tool holders. In order to be able to process ultra-hard cutting materials such as PCD, CVD-D, UltraDiamond (binderless) and CBN with precision tools economically, we recognized early on that we had to develop further from the old production technology „grinding“ to new technologies such as the „laser ablation process“.

                    • Cutting materials

                        • PCD Diamond

                        • Polycrystalline diamond (PCD), the well-known standard diamond
                          PCD is a synthetically produced, extremely tough, intergrown mass of diamond particles with random orientation in a metal matrix. It is produced by sintering selected diamond particles at high pressure and high temperatures.

                          Graphite serves as a catalyst so that the PCD crystals grow together. PCD has high thermal conductivity and good heat dissipation out of the cutting area. In addition, PCD has the highest flexural strength of all cutting materials.

                          PCD is very suitable for machining aluminium with a Si content of up to 12% and/or other abrasive fillers. The hot hardness is approx. 750°C, the areas of application are similar to those of CVD thick film diamond, however, the high economic efficiency of CVD thick film comes into play with hard-brittle materials or aluminium with a Si content of 12% or more.

                          With PCD you can machine materials like:
                          • Aluminium
                          • Zinc
                          • Brass
                          • Plastics
                          • GFRP (*First choice CVD-D)
                          • CFRP (*First choice CVD-D)
                          • Copper
                          • Graphite coarse-grained
                          • Ceramic green compact
                          • Carbide green compact

                        • CVD-D Diamond

                        • CVD thick film diamond (CVD-D), the star among diamond cutting materials
                          For machining hard-brittle materials such as ceramics, glass and glass-ceramics, hard metal, MMC and fibre composites such as CFRP and GFRP. Due to the lack of a bonding matrix, the diamond content is much higher than with PCD. In the group of ultra-hard cutting materials, binderless CVD-D is one of the hardest, artificially produced diamond cutting materials.

                          CVD-D is characterised by a high hardness as well as a high wear resistance. These properties make CVD-D the perfect cutting material for machining abrasive materials. Compared to PCD, which is damaged by the abrasive particles due to its soft metallic binder phase, the CVD-D cutting edge remains stable due to its binderless anchoring in the diamond matrix.

                          If CVD-D is used correctly, the tool life can be increased by up to 10 times (and even more) compared to PCD!

                          With CVD you can machine materials like:
                          • Aluminium >10%Si
                          • GFRP
                          • CFRP
                          • MMC
                          • Carbide >8% Co
                          • Tungsten copper
                          • Tungsten
                          • Graphite fine-grained
                          • Magnesium

                        • UltraDiamond

                        • Binderless diamond (UltraDiamond), the hardest single crystal
                          Single-crystal elements for our tool cutting corners are lasered out of diamond blanks in a defined orientation using laser segmentation technology. This new technology makes it possible to solder a monocrystal (UltraDiamond) onto any tool carrier under high vacuum, in addition to the highly hard polycrystalline cutting materials like PCD and CVD-D. Compared to PCD, the tool life can be increased by approx. 15-25 times and to CVD-D by approx. 2-5 times.

                          The areas of application are similar to PCD and CVD-D, but this monocrystalline cutting material offers a further significant increase in tool life for all applications where PCD and CVD-D reach the limits of economic viability.

                          Economical machining of very hard, highly brittle materials such as: Ceramics, glass, glass-ceramics and hard metals with low cobalt or nickel binder (
                          With UltraDiamond you can machine:
                          • Carbide
                          • Ceramic Glass ceramic
                          • Highly abrasive and brittle, non-ferrous materials

                        • CBN for hard turning

                        • Polycrystalline cubic boron nitride (CBN), chemically resistant and stable at high temperatures up to 1.400°C
                          Boron nitride powder is the starting point for the production of CBN, which has been available since the end of the 1960s. It is produced under high pressure as well as at temperatures of over 1,500°C and specially adapted to the final application through many different substrates.

                          Today, CBN is considered the second hardest material after diamond cutting materials!

                          The applications of CBN are in the automotive industry, aerospace, tool and mould making and mechanical engineering. The wide spectrum as a cutting and abrasive material includes hardened steels, cast iron, chilled cast iron, sintered materials, stellites, nickel and cobalt-based superalloys. In many applications, cubic boron nitride is preferred to diamond cutting materials because it is absolutely stable in air at temperatures up to 1,400°C. Diamond, on the other hand. Diamond, on the other hand, begins to decompose at a temperature of approx. 750°C.

                          Compared to PCD, CBN is also characterized by its chemical resistance to ferrous materials.
