What is the definition of "faceplate"?
A special fixture that is designed to hold a workpiece as it rotates on the lathe or turning center. A faceplate is often required if the workpiece is not cylindrical.

Class Vocabulary

Vocabulary TermDefinition
bar stock Stock that is sold in the form of long cylindrical, hexagonal, or square bars.
cast aluminum Aluminum that is poured as a liquid into a mold and cooled into a solid shape. Chuck jaws are often made of cast aluminum because it is easily machined.
center The device located in the tailstock of a lathe or turning center that supports the end of a cylindrical workpiece opposite the spindle.
chuck A workholding device with three or four jaws that clamp and hold a cylindrical workpiece as it rotates on a lathe or turning center.
collet A tapered workholding device with prongs that grip a workpiece passing through a hole in the center. Each collet is designed to match a specific workpiece diameter.
counterweight A weighted device that is used to properly balance a rotating workpiece or workholding setup on the lathe or turning center.
faceplate A special fixture that is designed to hold a workpiece as it rotates on the lathe or turning center. A faceplate is often required if the workpiece is not cylindrical.
fixture A customized workholding device that is designed to effectively support, locate, and hold a specific type of workpiece. A workpiece with multiple, complex dimensions often requires a dedicated fixture.
four-jaw chuck A chuck that uses four jaws to surround the part. Most four-jaw chucks are independent chucks, with jaws that open and close independently of one another.
hydraulic power Power created by the motion and pressure of fluids.
independent chuck A chuck with jaws that open and close independently. Independent chucks can be adjusted to accommodate irregularly shaped workpieces.
lathe A machine tool commonly used to create cylindrical forms. A lathe holds a cylindrical workpiece on one or both ends. The cutting tool is gradually passed along the surface of the rotating part.
low-carbon steel Carbon steels that contain less than 0.3% carbon. Low-carbon steels are easy to form, and they are used to make machinable chuck jaws.
milling machine A machine that uses a multi-toothed milling cutter to remove metal from the workpiece. A milling machine is most often used to machine flat or rectangular workpieces.
range The difference between the smallest and widest workpiece diameter that a chuck can hold between its jaws.
self-centering chuck A chuck with jaws that open and close together. Self-centering chucks accurately position a workpiece along the centerline of the chuck.
serrated Having a surface with a series of small teeth or notches. Serrated vise jaws offer improved gripping strength.
spindle On a lathe or turning center, the part of the machine that rotates while the workpiece is held in a chuck, collet, or faceplate.
stock Raw material that is used to make manufactured parts. Stock is often sold as bar stock or flat plate stock.
tapered Gradually decreasing in size from one end of the object to the other. Collets are tapered.
three-jaw chuck A chuck with three jaws. Most three-jaw chucks are self-centering, with jaws that open and close in unison.
turning A machining operation used to make cylindrical parts. A single-point cutting tool passes along the outer surface of a cylindrical workpiece as it rotates, and gradually removes a layer of material.
universal workholder A workholder that is designed to accommodate a variety of workpiece sizes and shapes. Chucks, collets, and vises are universal workholders.
vise A workholding device with one fixed jaw and one moveable jaw. Vises are often used to hold simple rectangular or cubic workpieces on a mill or machining center.
workholding device A device used to locate and hold a workpiece. The workholding device references the tool performing the operation on the part being held.
workpiece A part that is being worked on. It may be subject to cutting, welding, forming, or other operations.
