MACHINE TOOLSBoring - The process of using a single-point tool to enlarge a pre-existing hole. Boring is commonlyperformed on a lathe but is also possible on a mill.Brasses - A non-ferrous alloy containing copper and zinc.Brazing - A joining process that is used to combine dissimilar metals at temperatures lowerthan welding.Brittle - Difficult to bend, stretch, or form without breaking. Brittle metals tend to producediscontinuous chips.Broach bar - A multi-point cutting tool with a series of progressively changing teeth that can bothremove metal and finish the surface of a workpiece in one pass.Broaching - The use of a cutting tool with a series of teeth that is used to change the shape ordimensions of a hole. Broaching can also be used to remove material from a workpiece surface.Broaching machine - A machine that uses a multi-point cutting tool to shape and finish either theinterior of a hole or the surface of a workpiece.Built-up edge - Deformed metal that adheres to the cutting edge of the tool under high pressuresand temperatures.Burr - A sharp, unwanted bit of material remaining on an edge after machining. Burrs canpotentially cut individuals and often interfere with assembly.Carbide - A common cutting tool material that is used to make both indexable inserts and solidcutting tools. They provide a cutting edge that is very hard and wear resistant. Carbide tools areoften coated.Carbide insert - A cutting bit made of hard material that has multiple cutting edges. Once a cuttingedge is excessively worn, it can be indexed to another edge, or the insert can be replaced.Carbon tool steel - A type of steel designed with improved wear resistance, toughness,and strength.Carriage - The section of the lathe that slides back and forth along the ways and supports thecross-slide and cutting tool.Case hardening - The heating of a metal within a carbon-rich environment to increase carbonlevels on the metal surface. Case hardening creates a hardened exterior shell.Cast - Metal that has been poured as a liquid into a mold and cooled into a solid shape.quakerchem.com | info@quakerchem.com© 2013 Quaker Chemical Corporation.

MACHINE TOOLSCasting - A metal part that is formed by pouring molten metal into a mold. The metal then coolsand solidifies into its final shape.Center - The device located in the tailstock that holds in place the end of the workpiece oppositethe spindle.Centerless grinding - A common grinding operation in which a cylindrical part is supported on awork rest blade and guided between a grinding wheel and a regulating wheel.Centrifugal force - A force that attempts to pull an object traveling in a cylindrical path away fromthe center of rotation.Ceramic - A hard, brittle material that can withstand high temperatures. Ceramic cutting toolsrequire high cutting speeds and rigid machinery.Cermet - Any cutting tool material consisting of ceramic particles in a metallic binder. Cementedcarbide tools are a type of cermet.Chamfering - Machining an angled edge around the end of a cylindrical workpiece.Chemical vapor deposition - A special process that uses chemical reactions to coat a cuttingtool at the atomic level with fine layers of coating material. Carbide tools are coated by chemicalvapor deposition.Chip - An unwanted piece of metal that is removed from a workpiece. Chips are formed when a toolcuts or grinds metal.Chip breaker - A device located on the cutting tool or toolholder that is designed to prevent chipsfrom forming into long pieces.Chipping - Tool wear resulting in the loss of small slivers from the cutting edge of the tool. Chippingis often caused by an excessive feed.Chromium - A shiny, hard, steel-gray metal used in ferrous alloys to add hardness and wearresistance to steel.Chuck - A device that holds a workpiece in place as it rotates. The chuck commonly has three orfour jaws that can be adjusted to fit various sizes.Circular saw - A power saw that cuts with a toothed or abrasive disk rotating at high speed.Circular sawing - The use of a round saw blade with teeth around its perimeter.quakerchem.com | info@quakerchem.com© 2013 Quaker Chemical Corporation.
