MACHINE TOOLSGrooving - The process of cutting a narrow channel or passageway into the outside diameter of acylindrical workpiece.Gummy - Excessively soft and difficult to machine. Gummy metals produce long, stringy chips.Hacksaw - A saw that contains a blade made of high-speed steel, molybdenum, or tungsten alloysteel that cuts in one direction.Hacksawing - The use of a long blade mounted in a bow-shaped frame. Cutting takes place using areciprocating, or back-and-forth, motion.Hardness - The ability of a metal to resist scratching and penetration.Head - The part of a drill press that contains the spindle and the motor.Headstock - The end of a lathe that holds the spindle and the drive that rotates the workpiece.Heat treatment - The heating and cooling processes used to change the structure of a material andalter its mechanical properties.High-speed machining - An approach to metal cutting using recent speed technology that allowsmachining centers to do more work. HSM uses small diameter tools to perform multiple, rapid,light cuts.High-speed steel - A material used in cutting tools to machine metals at high cutting speeds. Highspeedsteel stays hard at high temperatures, has great hardness, and is resistant to abrasion.High-velocity machining - Another term used for high-speed machining. Some manufacturers preferthis term because it emphasizes other variables besides spindle speed.Honing - A process that uses abrasive stones to reshape dimensions from a previous operation.Honing can also be used to achieve a certain surface finish. \ A precision abrasion process inwhich a relatively small amount of material is removed from a surface by means of abrasive stones.The goal is to obtain a desired finish or extremely accurate features.Hot working - The shaping of metal at temperatures above its recrystallization phase. Hot workingtypically leaves a tough, scaly surface on the metal.HSK toolholder - A type of toolholder with a short, hollow taper that contacts the spindle on twosurfaces. HSK toolholders provide improved rigidity during HSM operations.Hybrid bearing - A bearing that consists of ceramic balls that travel within a steel race.Hydrostatic bearing - A bearing that uses pressurized fluid to support the rotating shaft.quakerchem.com | info@quakerchem.com© 2013 Quaker Chemical Corporation.
