MACHINE TOOLS - Quaker Chemical Corporation

MACHINE TOOLSSuperalloy - An alloy consisting of numerous alloying elements that is very expensive and designedto exhibit certain mechanical properties at elevated temperatures.Surface grinding - A common grinding process generally used on flat surfaces that feeds aworkpiece beneath a rotating grinding wheel.Tailstock - The part located at the end of a lathe opposite the headstock that supports the end oflonger workpieces.Tap - A multi-point tool that is used to cut internal threads into a hole.Taper turning - 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.Tapping - The process of cutting internal threads in a round hole with a multi-point tool.Threading - The process of cutting a long, spiralling groove into a workpiece with a single-point tool.Threading processes are essential for the creation of fasteners.TiAlN - Titanium aluminum nitride. TiAlN coatings help improve the wear resistance of carbideinserts at elevated temperatures.Titanium carbide - TiC. A more recent material used to make carbide cutting tools that offersimproved chemical stability and crater resistance.Titanium nitride - TiN. A compound used to coat high-speed steel and carbide tools toreduce friction.Tolerance - The unwanted but acceptable deviation from the desired dimension.Tool chatter - The development of surface imperfections on the workpiece caused by vibrations ofthe cutting tool.Tool failure - The point at which a cutting tool is no longer useful for machining. Flank wear,chipping, and cratering all eventually lead to tool failure.Tool life - The length of time that a cutting tool can function properly before it begins to fail.Tool wear - The rate at which the cutting edge of a tool wears away during machining.Torque - The ability of a machine to exert a torsional force at a particular speed. The torque of amachine will vary across its speed range.Toughness - The ability of a metal to absorb energy without breaking or fracturing.quakerchem.com | info@quakerchem.com© 2013 Quaker Chemical Corporation.
