Turning and Boring A specialized treatise for machinists, students in the industrial and engineering schools, and apprentices, on turning and boring methods, including modern practice with engine lathes, turret lathes, vertical and horizontal boring machines

Turret lathes are adapted for turning duplicate parts in quantity. The characteristic feature of a turret lathe is the turret which is mounted upon a carriage and contains the t...

It is often necessary, in connection with lathe work, to turn parts tapering instead of straight or cylindrical. If the work is mounted between the centers, one method of turnin...

The standard "engine" lathe, which is the type commonly used by machinists for doing general work, is one of the most important tools in a machine shop, because it is adapted to...

When threads are cut in the lathe a tool _t_ is used (see Fig. 2), having a point corresponding to the shape of the thread, and the carriage is moved along the bed a certain dis...

A boring machine of the horizontal type is shown in Fig. 1. The construction and operation of this machine is very different from that of a vertical boring mill and it is also u...

Notwithstanding the fact that a great variety of work can be done in the lathe, the number of turning tools required is comparatively small. Fig. 1 shows the forms of tools that...

=Turning a Flywheel on a Vertical Mill.=--The turning of a flywheel is a good example of the kind of work for which a vertical boring mill is adapted. A flywheel should preferab...

All the different types of turning machines now in use originated from the lathe. Many of these tools, however, do not resemble the lathe because, in the process of evolution, t...
