Front Cover: MBN NANOMATERIALIA
MBN has developed a comprehensive range of materials and solutions to meet the diverse requirements of the diamond tool industry, offering products engineered to specific applications, from stone and ceramic processing to glass and concrete. The Mechanomade® series, based on high-performance iron-copper composites, represented the first generation of cobalt-free materials developed by MBN for the production of Fickert tools used in hard-stone polishing lines. This family was subsequently complemented by Nanoplus metal binders, formulated without critical elements such as copper and nickel, providing a more sustainable solution particularly suited to ceramic processing. MBN has also developed dedicated solutions for pressureless sintering, with particular focus on the production of diamond beads for wire cutting.

30)Diamond Pauber, when diamond wire is born in the quarry
A diamond wire does not simply begin on the production line. It begins much earlier: by observing a machine at work, understanding the material to be cut, talking to those who work in the quarry every day and identifying where a solution can be improved. For more than 45 years, this approach has guided Diamond Pauber in the development of its diamond wires: starting from real operating conditions and transforming needs, challenges and production goals into practical technical solutions. Because there is no single requirement in a quarry. In some situations, cutting speed and wire life are the main priorities. In others, safety plays a decisive role. Elsewhere, limited space, unusual cutting geometries or an unexpected event during cutting may call for a completely different solution. Some of the technologies developed by Diamond Pauber were created precisely in response to these different needs...34)Ferriera di Cittadella: 70 years of history, from steel to diamond wire
Seventy years are not just a number. They are a thread connecting generations, bold decisions and the ability to reinvent yourself without losing who you are. Ferriera di Cittadella celebrated this milestone on 17 May, at its Riese Pio X plant, together with employees, their families and friends: a community first, a company second. A moment to stop and recognise how much of the human experience can accumulate over seven decades of shared work. The Pirota family’s connection to steel goes back a long way: to a hardware shop in Milan in the 1800s, followed by a steel mill plant built in Friuli after the Second World War...40)DBC Makina: innovating the future of “Total Core Drilling Technologies”
Founded in 1991, DBC Makina currently develops, manufactures, and markets drilling equipment for mineral exploration and geotechnical engineering. As one of the few companies globally capable of manufacturing “Total Core Drilling Technologies”, DBC produces all necessary machinery and equipment for core drilling in-house - from diamond bits to drilling rigs - and exports them to developed countries worldwide. Underground and surface drilling rigs of all capacities are manufactured. Additionally, through joint efforts with the world’s leading drilling companies, DBC has developed specialized rigs suitable for helicopter transport, ATEX Group 1 M2 compliance for explosive environments, and operations in arctic conditions...44)The technological evolution of diamond tool operations: from the tool to the work system
Diamond-tool operations have changed profoundly in recent years. This evolution is evident in the tools themselves, but equally so in the machines that drive them. Core bits, blades, diamond wires and grinding tools have progressively become higher-performing and more specialized; at the same time, the equipment that drives them is more compact, more powerful, electronically controlled and, in many applications, automated or remotely operated. This is not simply a matter of having more powerful machines or tools that cut faster. The very concept of the work process is changing: from a machine-and-tool pairing, we are progressively moving towards a genuine work system in which multiple components must interact correctly to deliver performance, precision and operational continuity...Innovation
51)Research progress on additively manufactured diamond tools – Part 2
Abstract: With their exceptional hardness and wear resistance, diamond tools hold an irreplaceable position in critical fields such as precision machining, geological exploration, and construction engineering. However, traditional manufacturing processes like powder metallurgy still face numerous limitations in terms of structural design optimization, the controllability of diamond particle distribution, and the shortening of production cycles. In recent years, additive manufacturing has emerged as a disruptive technology that precisely constructs three-dimensional structures in a layer-by-layer manner, offering new possibilities for the customized design and functionally integrated manufacturing of high-performance and complex-structured diamond tools. This paper systematically reviews the recent research progress on the additive manufacturing of diamond tools. It focuses on summarizing the fabrication characteristics and performance of metal-bonded diamond tools, resin-bonded diamond tools, and ceramic-bonded diamond tools prepared by different additive manufacturing processes. On this basis, the paper further discusses the key technical challenges and future development directions in this field, with the aim of providing a theoretical reference and technical guidance for the design optimization and engineering applications of additively manufactured diamond tools...66)Application of response surface methodology in lunar deep rock layer drilling experiments in low-temperature and anhydrous environments
Abstract: The Chang’e project has completed a sampling mission of the shallow lunar soil layer; however, the exploration of the deep lunar rock layer remains unaddressed. To further investigate the feasibility of deep lunar rock drilling and identify the factors affecting the rate of penetration (ROP) and power in low-temperature, H2O less environment, a model was developed. This study utilized the Box-Behnken method to design a response surface experiment, where the number of polycrystalline diamond compact (PDC) cutters, the backward inclination angle, the chip removal conditions, and the temperature were considered as the key influencing factors. A response surface model for ROP and power was established. The results indicated that the number of PDC cutters, the backward inclination angle, the chip removal conditions, and the temperature significantly affected both ROP and power, with the interaction between the temperature and the backward inclination angle having a particularly strong impact on the ROP. The regression model demonstrated high predictive accuracy for both ROP and power, with goodness of fit (R2) values of 0.95 and 0.96, respectively. The optimal combination of the backward inclination angle, number of PDC cutters, temperature, and chip removal conditions, derived from the response surface experiment, was 25°, four, -15 °C, and 1, respectively, which resulted in high drilling efficiency and low power consumption. This study offers new insights for the design of deep lunar drilling experiments, as well as support for the future optimization of drilling tools...News and Events
