The Model RSV is a rotating spindle viscometer that uses the constant angular velocity method to measure viscosities at specific temperatures. These measurements are then used to generate a curve of ...

along a rotating grinding wheel. This abrasive process removes a layer of material from the surface of the workpiece. Its cutting variables include wheel speed, spindle speed, surface or work speed, ...

Spindle whorls are round ... indicating a deliberate design for balance during rotation. The research team used three-dimensional scans and advanced computational technology to analyze the ...
