Screwing Machine

| View Cart ⇗ | Info

“The machine is in fact a lathe with a few special features, such as the hollow mandrel, which enables it to operate upon a bar of any length. Dies mounted on a modified form of slide-rest cut the thread to the full depth at a single traverse, and a simple arrangement enables nuts to be tapped with equal facility. In some other varieties of screwing machines, more particularly those intended for hand power only, the outward resemblance to the turning lathe is less apparent, but if their action is looked into it will be found that in them as in almost all machine tools it is the principle of the slide which is mainly conducive to their success.” —The Encyclopedia Britannica, 1903
