Class Vocabulary

Term	Definition
ANSI	The American National Standards Institute. ANSI is a non-profit organization that works to standardize many aspects of the business marketplace.
arbor press	A device used to install a bushing in a jig plate. The use of an arbor press prevents any distortion of the bushing.
bushing	A hardened steel tube used to guide cutting tools such as drills and reamers.
case-hardened steel	Steel that has a surface layer hardened by special heat treating methods.
concentricity	The degree to which a given dimension resembles a perfectly round circle or cylinder.
counterbored	A hole that has been slightly widened from one end to a particular depth. A counterbored hole typically provides space for a recessed bolt or screw head.
flat clamp	A small clamp with a flat edge that is used to lock a bushing in place.
ground	A surface that has been machined with an abrasive to improve finish and achieve accurate dimensions.
gun drill bushing	A special type of bushing that is used to guide a drill for deep-hole drilling operations.
head press fit bushing	A basic type of bushing with a rim or collar at the top for extra loads. Head press fit bushings are permanently installed.
headless press fit bushing	The most basic type of bushing. A headless press fit bushing is simply an accurate, hardened metal tube. These bushings are permanently installed.
interference	The degree that the diameter of an internal part exceeds the diameter of the external part when being fitted in a hole.
jig	A workholding device used to position and hold a workpiece while guiding the location of the cutting tool. Jigs are the only workholding device that use a bushing to guide the tool.
knurled	A surface that has been marked with small diamond-shaped impressions. Knurled surfaces are easier to grip.
liner bushing	A type of bushing that acts as a sleeve or receptable for slip and slip-fixed renewable bushings.
load	The weight or burden that is supported by a material.
oil groove bushing	A special type of bushing that contains interior grooves to encourage the flow of cutting fluids during machining operations.
reaming	The use of a cutting tool to smooth or enlarge a previously drilled hole.
removable bushing	Another term for a slip renewable bushing.
replaceable bushing	Another term for a slip-fixed renewable bushing.
slip renewable bushing	A type of bushing that can be inserted or removed between operations and held in place with a lockscrew or clamp. These bushings are replaced after excessive wear.
slip-fixed renewable bushing	A type of bushing that can be installed and held in place with a lockscrew or clamp. These bushings are replaced after excessive wear.
soft material bushing	A special type of bushing with a serrated or grooved exterior that helps hold the bushing in place when installed in softer materials.
tolerance	The unwanted but acceptable deviation from the desired dimension.
tool steel	A type of steel designed with high wear resistance, toughness, and strength.
workholding device	A device used to position and hold a workpiece. The workholding device references the tool performing the operation on the part being held.
