Brown & Sharpe Single Spindle screw machine. Model #2 Square Base, four-slide machine. 1 1 ⁄ 2 cap or 1 3 ⁄ 4 Air Feed.. Screw machines, being the class of automatic lathes for small- to medium-sized parts, are used in the high-volume manufacture of a vast variety of turned components.
Early lathes, those prior to the late medieval period, and modern woodworking lathes and potter's wheels may or may not fall under this definition, depending on how one views the headstock spindle itself; but the earliest historical records of a lathe with direct mechanical control of the cutting tool's path are of a screw-cutting lathe dating ...
A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles.
Second operations can be completed by using a sub-spindle, which is co-axial to the main spindle, but faces the other direction. This allows the part to be removed from the main spindle, and for additional features to be machined in the back side of the part. Plasma cutter: Involves cutting a material using a plasma torch. Commonly used to cut ...

The introduction of CNC-controlled lathes has provided a practical, everyday solution via automated CSS Machining Process Monitoring and Control. By means of the machine's software and variable speed electric motors, the lathe can increase the RPM of the spindle as the cutter gets closer to the center of the part.
Fay automatic lathe [1] The Fay automatic lathe was an automatic lathe tailored to cutting workpieces that were mounted on centers (tools with pointed ends to accurately position a center-drilled workpiece about an axis, either directly or by using a mandrel ).
The use of automatic changers increases the productive time and reduces unproductive time. It provides the storage of the tools which are returned automatically to the machine tool after carrying out the required operations, increases the flexibility of the machine tool, makes it easier to change heavy and large tools, and permits the automatic ...
