An external cylindrical grinder is a machine tool that adds the outer surface and shoulder end face of cylindrical or conical workpieces. It can not only grind the outer surface of the workpiece, but also the cutting surface and end face of the workpiece.
Usually, machine tools use grinding wheels as grinding tools to grind the surface of workpieces, which also belongs to the field of metal cutting. The structure of a machine tool is not complicated. From its appearance and the grinding action of the grinding wheel in the working area, it can be basically determined that an external cylindrical grinder is usually composed of a worktable, a headstock, a tailstock, a grinding wheel holder, a feed mechanism, as well as some electrical systems and hydraulic control devices.
The bed is the core of the entire machine tool and the platform that carries all the devices and components on the machine tool. At the same time, the bed is also an important indicator for judging its quality. A good machine tool bed is made by integral casting and can effectively melt the parts that are later mounted on the bed. The worktable is the main area for grinding processing, and the worktable of an external cylindrical grinder will have some hydraulic devices that fix the workpiece in conjunction with a top pin to accurately position the workpiece. The head frame, tail frame, and grinding wheel frame are respectively the worktable head fixing frame, worktable tail fixing frame, and grinding wheel fixing frame, whose main function is to fix the components at the corresponding positions.
