process of turning into a cylindrical object
spinning
a machine used to rub against something till it turns into a powder
Grinder
to increase the diameter
Taper
a substnace used for cleansing or polishing a hard substance
Abrasive
Shear cutting
bends a metal without changing the surface area
A device used to cut or shape a tool, especially a rotating edge.
Milling
Applying power and heat to form metal
Flame spraying
Abrasives are blown against an object
Sandblasting
Coating applied by dipping metal in molten alliunium
Hot Dipping
Uses wedging action of the screw thred to camp parts together
Threaded fastener
Assemble parts not requring close tolerances
Machine Bolts
Semi permanent fasteners to prevent slippage of a shaft in a race or shaft
Sets screws
Headless bolt threaded entire lenght
Stud bolt
Removed using an extracor.drill a hole in remaking exctartor
Broken bolt
Fastening device put on bolt or screw. ( unfishined except for screw)( Mahcined on beairng face)
nut( Regular)(semiregular)
Provide increased beairng surface for bolt heads and nuts
Washers
(Produce thread as they are driven) ( cut threads as they are driven)(Hammered into a drilled or punched hole)
(Thread forming screws, Thread cutting screws, Hammer screw/drive screw)

lathe bed
supports outer end of work on lathe
dead center
a movable fixture on the lathe that mounts in ways to accommodate different fixtures
Tailstock
This part of lathe conrols and support the ecutitng tool.
Lathe Carriage
After drilling slightly undersize, a blank is
used to make a hole accurate in diameter and
finish.
