HISTORY
We started our activity in the seventies dealing in construction and reconditioning of mechanical tools and equipment.
In early 1980 the growing need of our clientele to improve their levels of production while at the same time reducing costs, induced us to build the first industrial diamond tools.

TODAY
With constant dedication and technological investment we are now able to construct not only PCD (polycrystalline) DIAMOND tools but also MONODIA (synthetic single-crystal) and NATURAL DIAMOND tools for the various sectors of use.
We also hold two system patents for special machining tools to work various types of materials.

MACHINE PARK
To safeguard product quality, we have staff and a machine park at our disposal such as to allow manufacturing all our tools in-house, from the design phase up to superfinishing and final tests.

TYPES OF MACHINING
Chip-removing machining, braze welding, grinding, electrical discharge machining, microdrilling, PCD grinding, microbrazing, sintering and superfinishing of the natural diamond.
