  2. Lathe - Wikipedia

    en.wikipedia.org/wiki/Lathe

    Modern metal lathe A watchmaker using a lathe to prepare a component cut from copper for a watch. A lathe (/ l eɪ ð /) is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about ...

  3. Copying lathe - Wikipedia

    en.wikipedia.org/wiki/Copying_lathe

    The Hermitage Museum, Russia, displays the Nartov's copying lathe used for ornamental turning: making medals and guilloche patterns designed by Nartov in 1721. [2] Nartov's lathe duplicated the pattern from a template to a blank, cutting to the preset scale. A probe traced the template and the cutter cut accordingly.

  4. Metal lathe - Wikipedia

    en.wikipedia.org/wiki/Metal_lathe

    A view inside the enclosure of a CNC Swiss-style lathe/screw machine. A Swiss-style lathe is a specific design of lathe providing extreme accuracy (sometimes holding tolerances as small as a few tenths of a thousandth of an inch—a few micrometers). A Swiss-style lathe holds the workpiece with both a collet and a guide bushing. The collet sits ...

  5. Turning - Wikipedia

    en.wikipedia.org/wiki/Turning

    A lathe is a machine tool used principally for shaping pieces of metal, wood, or other materials by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into the work causing the cutting action. Lathes can be divided into three types for easy identification: engine lathe, turret lathe, and special purpose ...

  6. Numerical control - Wikipedia

    en.wikipedia.org/wiki/Numerical_control

    A CNC machine that operates on wood CNC machines typically use some kind of coolant, typically a water-miscible oil, to keep the tool and parts from getting hot. A CNC metal lathe with the door open. In machining, numerical control, also called computer numerical control (CNC), [1] is the automated control of tools by means of a computer. [2]

  7. Turret lathe - Wikipedia

    en.wikipedia.org/wiki/Turret_lathe

    These machines can execute many part-cutting cycles without human intervention. Thus the duties of the operator, which were already greatly reduced by the manual turret lathe, were even further reduced, and productivity increased. These machines use cams to automate the sliding and indexing of the turret and the opening and closing of the chuck.

  8. Speeds and feeds - Wikipedia

    en.wikipedia.org/wiki/Speeds_and_feeds

    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.

  9. Screw-cutting lathe - Wikipedia

    en.wikipedia.org/wiki/Screw-cutting_lathe

    Henry Maudslay's early screw-cutting lathes of circa 1797 and 1800.. A screw-cutting lathe is a machine (specifically, a lathe) capable of cutting very accurate screw threads via single-point screw-cutting, which is the process of guiding the linear motion of the tool bit in a precisely known ratio to the rotating motion of the workpiece.
