Tiny metal spheres are needed for tiny ball valves and tiny ball bearings, which are needed for all kinds of miniaturized machines. Hollow spheres are lighter, and thus have less inertia, and thus can be made to move faster in these very small applications, where response time is often critical. But how do you make a hollow metal sphere 2mm across? Turns out …

1. The Force with which a hollow, buoyant Steel Sphere is propelled upwards from under water at significant depth changes as the sphere ascends to higher elevations closer to the water surface? It seems counter-intuitive to me that the force exerted on the sphere 3 meters below the water surface, is identical to the force a 1000 meters below ...

Gong et al. [14] used a hollow-sphere abrasive belt to grind titanium alloy and found the abrasive grains worn in the form of macro fracture that played a role of self-sharpness. It is generally stated that serious abrasive belt wear would reduce material removal efficiency and the consistency of surface integrity when grinding large-size or ...

Yes, high-speed machining can be done without a cutting fluid. The main purpose of a cutting fluid is to lubricate and to remove heat, usually accomplished by flooding the tool and work piece by the fluid. In high speed machining, most of the heat is conveyed from the cutting zone through the chip, so the need for a cutting fluid is less.
