The Turning Lathe
Anatomy of a Turning Lathe
The novice who has never examined a Turning Lathe, but, having seen others using it, thinks he should also like to try his hand at the work, naturally wants to know its construction. He hears of chucks, and mandrels, headstocks, tailstocks, steady rests, tool posts, etc. but the terms convey to his mind nothing but mystery.
The construction and perfection of all this magnificent array of highly developed machinery has only been made possible through the use of the machines for the use of the machinist, the machine tools of the present day, which must first have been perfected and adapted to the many needs and requirements which the advanced state of mechanical science demanded. These machine tools were made possible by the earlier examples of the most simple devices.
In this direction, chiefly, in our own time, the foot lathe, by which many of the earlier tools and machines were for the most part built; and as new uses for it were found, new devices, attachments, and accessories were devised and applied, and in this gradual development and improvement in its design, its construction, and the materials of which it is built, the early and crude foot lathe has become the magnificent machine of the present day, and in which the American mechanic takes a just and pardonable pride.
It is conceded that of all the machines employed by the mechanic to aid him in his work the lathe holds the honor of having been the first machine tool, From it, in one way or another, all other machine tools have been developed; as they are, practically considered, but modifications of it, or special tools for doing quicker and better, the several operations which may be, and formerly were, performed upon the lathe.
The immense variety of work performed by turning machines necessitates great variations in their construction; but mode of operation is always the same, and consists essentially in fixing the work in position by two pivots, or otherwise, causing it to revolve freely around an axis of revolution, of which the two pivots are the poles, and holding a chisel or other cutting-tool so as to meet it during its revolution, taking care that the cutting tool be held firmly and steadily, and moved about to different parts of the work till the required shape is obtained.
Wood Turning Basics – Lathe & Tools 2 of 2
Beginning wood turning. A look at lathe tools and a cutting exercise.
The essential elements of a simple metal turning lathe are :
- suitable means for supporting and holding the work upon centers;
- proper mechanism for rotating the work;
- and a cutting-tool properly held and supported upon a
- traveling device actuated by suitable mechanism.
- The first of these essentials comprise the bed, head-stock, and tail-stock
- The second essential comprises the driving
mechanism, consisting of the driving-cone, back gearing, etc. - The third essential consisting of the carriage, tool block, and cutting tool,with the necessary gearing for moving it, and the connecting parts for transmitting power for that purpose from the main
spindle of the lathe.
Here are the major parts of the turning lathe.
- Bed and appendages, including the legs or cabinets, lead-screw, the feed-rod, carriage
rack, tail-stock, moving rack (when the lathe is large enough to require one) - Head-stock and appendages, including such feed-gears as
are necessary to connect with the feed-rod in case of a geared feed. A quick change gear device may be used and is not an integral part of the bed or head. - Tail-stock and appendages, such as holding-down bolts,
binders, and, when the lathe is large enough to require it, the mover bracket, gears, shafts and crank; and if the tail-spindle is handled by a hand-wheel in front, the brackets, shafts, spur and bevel gears, etc. - Carriage and appendages, including gibs and a solid tool block if one is used. If the lathes are built with compound rests they may be classed with the carriage.
- Apron and appendages, including the apron in its complete assembled form ready to attach to the carriage.
- Rests, including the compound rest (when not classed with the carriage, the full swing, pulley or wing rest, center rest, back rest.
- Countershaft and its appendages, including the hangers, pulleys or friction pulleys as may be necessary.
- Taper attachments, special tool holders, or tool-rests, and all similar parts that are deemed extras.
- Change-gears are sometimes listed as a part of the bed or these may be part of a special quick change device or a part of the head-stock or the bed.
