MACHINE TOOLSInclusion - A substance that is unintentionally present in a metal and that often hasundesirable properties.Indexable insert - A cutting bit that has multiple cutting edges. Once a cutting edge is excessivelyworn, it can be indexed to another edge, or the insert can be replaced.Inner diameter - The interior surface of a hole in a workpiece.Insert - A cutting bit that has multiple cutting edges. Once a cutting edge is excessively worn, it canbe indexed to another edge, or the insert can be replaced.Interrupted cutting - Any machining operation involving a cutting edge that enters and exits aworkpiece. Milling operations involve interrupted cutting.Keyway - A rectangular slot or groove that is machined down the length of a hole.Knee - The device supported by an elevating screw that raises and lowers and guides the back andforth motion of the saddle.Knurling - A forming process that adds a pattern on the exterior of a workpiece, either for cosmeticreasons or better handling.Lapping - An abrasive process that removes the last bit of unwanted material. A lapping processsometimes uses an abrasive paste that is rubbed across the part to gradually smooth it.Lathe - A machine tool that holds a cylindrical workpiece at one or both ends and rotates it whilevarious cutting tools remove material. Turning is a common operation performed on the lathe.Lead - A bluish white metal that is very soft and ductile. Though lead can be added to steel toimprove machinability, it is less desirable because of the risk of lead poisoning.Leadscrew - The long, threaded device that controls the precise movement of the carriage ona lathe.Linear motor - A flat motor that uses a magnetic field instead of mechanical force to power themotion of machine tool components.Machinability - The relative ease with which material can be removed from metal by machineprocesses such as cutting or grinding.Machine tool - A power-driven machine that uses a cutting tool to create chips and remove metalfrom a workpiece. These tools include cutting tools, workholding devices, punches, and othermanufacturing tools.quakerchem.com | info@quakerchem.com© 2013 Quaker Chemical Corporation. All rights reserved.
