  1. The machining of ISO N materials such as wrought aluminium alloys and cast aluminium alloys or copper presents a challenge for tools. Walter is launching a product line developed especially for this with the MC267 Advance solid carbide milling cutters. The universal milling cutters with centre cut and diameter of 1 to 20 mm are suitable for a wide range of applications, including sectors involving micromachining operations, such as the electronics industry. With two or three flutes, they can be used on machines with a different performance spectrum, for roughing as well as semi-finishing and finishing. The combination of geometry (45° helix angle) and low-vibration micro geometry enables a high level of stability and process reliability.
  2. Which company is manufacturing trains for India's first Regional Rapid Transit System (RRTS)?
  3. GKN Aerospace is leading the H2JET national partnership programme in Sweden, which aims to develop technical solutions for three key engine subsystems for medium-range civil aircraft using H2-propulsion. Hydrogen is projected to play a crucial role in aviation's decarbonization strategy because it can efficiently power aircraft while producing only water as a by-product. H2JET focuses on direct combustion, whereas GKN Aerospace's 'H2GEAR' venture, which was launched earlier this year, focuses on generating onboard electrical power via a fuel cell.
  4. particulate air filter is a device composed of fibrous, or porous materials which removes solid particulates such as dust, pollen, mold, and bacteria from the air. Filters containing an adsorbent or catalyst such as charcoal (carbon) may also remove odors and gaseous pollutants such as volatile organic compounds or ozone.Air filters are used in applications where air quality is important, notably in building ventilation systems and in engines. Some buildings, as well as aircraft and other human-made environments (e.g., satellites, and space shuttles) use foam, pleated paper, or spun fiberglass filter elements. Another method, air ionizers, use fibers or elements with a static electric charge, which attract dust particles. The air intakes of internal combustion engines and air compressors tend to use either paper, foam, or cotton filters. Oil bath filters have fallen out of favour aside from niche uses. The technology of air intake filters of gas turbines has improved significantly in recent years, due to improvements in the aerodynamics and fluid dynamics of the air-compressor part of the gas turbines.
  5. The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity can be conceptualized as quantifying the internal frictional force that arises between adjacent layers of fluid that are in relative motion.
  6. Who has been appointed as the new Chief Executive of Mahindra Electric Mobility Limited (MEML)?
