High-speed steel stayshard at high temperatures and resists abrasion.A turning machine in which the spindle axis is parallel to the ground.The precise positioning of a tool during an operation.Cutting operations that take place on the interior surface or hole of a cylindricalworkpiece.A tool commonly used to machine cylindrical forms. It is generally considered thebackbone of the machine shop.A feature that equips the turret with power-driven cutting tools such as end millsand drills. These tools can perform cutting operations off-center while theworkpiece is held still in the spindle.A multi-point tool that is used to remove metal from the surface of a workpiece.An operation performed on a lathe that feeds a tool to create an angled edge on theworkpiece.An operation performed on the lathe that creates a circular channel or passagewayaround the exterior of a workpiece.The process used to machine a long, spiraling ridge down the outer surface of aworkpiece.Cutting operations that take place on the outer surface of a cylindrical workpiece.A device used to catch a part once it is separated from the stock in a bar machine.A multi-point cutting tool with straight cutting edges used to enlarge or smoothholes that have been previously drilled.The process of using a multi-point tool to smooth the interior surface of a hole.The speed at which a workpiece spins on a lathe.A special motor used in CNC machines that turns the ballscrew to move parts withprecision.A machining tool that has one single cutting edge.The device located in the headstock that holds the workpiece in place to rotate it.Raw material that is used to make manufactured parts.A long structure that supports bar stock as it passes through the bar machine.The device at the end of a lathe that supports the end of longer workpieces.An operation performed on a lathe that feeds a tool at an angle to the length of theworkpiece in order to create a conical shape.A long, spiraling ridge that winds down the length of a workpiece.The unwanted but acceptable deviation from a desired dimension.The device used to rigidly hold a carbide insert in place. Toolholders are available instandardized sizes.The machining process used to make cylindrical parts. Turning is commonlyperformed with a lathe.A lathe that is controlled by a computer running programs driven by numerical data.Sophisticated turning centers can also perform a variety of drilling and millingoperations.
