Cylindrical grinding machine is a kind of grinding machine used to reshape the exterior of objects. Cylindrical grinders can process various shapes, but the object must have a central axis of rotation. This includes, but is not limited to, shapes such as cylinders, ellipses, cams, or crankshafts. The hydrostatic guide rail and hydrostatic ...

Conical surfaces can be applied in the valves of liquid seal. In the fuel injection unit of a diesel engine, an outer conical surface at the tip of a slender needle works with an inner conical surface as injector-body seat to realize the switching and sealing of a fuel passage. So far, the conical surfaces are usually machined by mechanical grinding. The small grinding wheels < ϕ3 …
