A vise or vice (British English) is a mechanical apparatus used to secure an object to allow work to be performed on it. Vises have two parallel jaws, one fixed and the other movable, threaded in and out by a screw and lever. The jaws are often flat but may have grooves, [1] adapt to the shape of the workpiece or be custom made. [2]
A vise grip is not a vise but a pair of lever-actuated locking pliers.
The etymology of vise can be tracked via Middle English vys Anglo-French vyz from Latin vitis "vine". [3] The tight grip of the mechanical device was likened to that of the twines of the plant.
A face vise is the standard woodworking vise, always securely attached to a workbench flush with its work surface. Its jaws are made of wood or metal, the latter usually faced with wood, called cheeks, to avoid marring the work. [4] The movable jaw may include a retractable dog to hold work against a bench dog.
A "quick-release" woodworker's vise employs a split nut that allows the screw to engage or disengage with a half-turn of the handle. When disengaged the movable jaw may be moved in or out throughout its entire range of motion, vastly speeding up the process of adjustment. Common thread types are Acme and buttress.
Traditional woodworking workbench vises are commonly either face vises, attached to the front of the workbench near the left end of its long side (for a right-handed worker), or end (or tail) vises, attached to or forming part of the right side of the narrow end of the bench.
An engineer's vise, also known as a metalworking vise, machinist's vise, or, informally, a "bench vise", is used to clamp metal instead of wood. It is used to hold metal when filing or cutting. It is sometimes made of cast steel or malleable cast iron, but most are made of cast iron. The jaws are often separate and replaceable, usually engraved with serrated or diamond teeth. Soft jaw covers made of aluminum, copper, wood (for woodworking) or plastic may be used to protect delicate work. The jaw opening of an engineer's vise generally equals its jaw width, though it may be wider.
An engineer's vise is bolted onto the top surface of a workbench, [5] with the face of the fixed jaw just forward of its front edge. The vise may include other features such as a small anvil on the back of its body. Most engineer's vises have a swivel base. Some engineer's vises marketed as "homeowner grade" are made of pot metal or a very low grade of iron.[ citation needed ] Many homeowner's bench vises have an exposed screw.
A combination-vise combines an engineer-style vise with a subsidiary set of curved serrated jaws below the main for clamping pipe. A pivoting base is standard.
A clamp-on vise is a light-duty bench vise secured to a board, table, or bench by a vise-type screw on its base which rarely is able to pivot.
A vacuum-mounted vise is a small engineer's vise secured by a suction cup base and is typically used by hobbyists for very light-duty work.
Machine vises are mounted on drill presses, grinding machines and milling machines. Abrasive chop saws have a coarse-threaded or cam-actuated machine-type vise built into the saw.
A pipe vise is used by a plumber to hold pipes for threading and cutting. There are two main styles, yoke and chain. [6] The yoke uses a top-mounted screw to clamp the pipe between two fixed angled jaws at its base; the chain style secures the pipe by wrapping it within a chain designed to adjust to length by link, tightened by a cam lever.
Other kinds of vises include:
A lathe is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis.
Limelight is a non-electric type of stage lighting once used in theatres and music halls, and was the first solid-state lighting device. An intense illumination is created when a flame fed by oxygen and hydrogen is directed at a cylinder of quicklime, which can be heated to 2,572 °C (4,662 °F) before melting. The light is produced by a combination of incandescence and candoluminescence. Although it has long since been replaced by electric lighting, the term has nonetheless survived, as someone in the public eye is still said to be "in the limelight". The actual lamps are called "limes", a term which has been transferred to electrical equivalents.
A collet is a segmented sleeve, band or collar. One of the two radial surfaces of a collet is usually tapered and the other is cylindrical. The term collet commonly refers to a type of chuck that uses collets to hold either a workpiece or a tool but has other mechanical applications.
A chuck is a specialized type of clamp used to hold an object with radial symmetry, especially a cylinder. In a drill, a mill and a transmission, a chuck holds the rotating tool; in a lathe, it holds the rotating workpiece.
A bench dog is a removable clamp used on a woodworking workbench to hold an item fast while being worked. It is characteristically used in concert with an adjustable dog on a bench vise, allowing an item compressed between the two to be held fast on each end, and if offset in both directions.
A lathe center, often shortened to center, is a tool that has been ground to a point to accurately position a workpiece on an axis. They usually have an included angle of 60°, but in heavy machining situations an angle of 75° is used.
A bench hook is a workbench appliance used in woodworking to hold a workpiece in place while crosscutting with a hand saw. A bench hook is a simple method used to improve accuracy and safety.
Julián Palacios Gutiérrez was a Spanish mining engineer and businessman who was recognized as the 1st President of Real Madrid from 1900 until 6 March 1902.
A pipe clamp is a type of clamp often employed in woodworking, piping or cabinet shops. When referring to woodwork or cabinet shops, pipe clamps are usually composed of commercially manufactured clamp heads or "jaws" and a length of common threaded pipe. The capacity of the clamp is determined by the length of the pipe used. When referring to piping, pipe clamps are used to connect the pipe to the pipe hanger assembly.
A holdfast or hold fast is a form of temporary clamp used to hold a workpiece firmly to the top or side of a wooden workbench or the top of an anvil.
Jack Betts, also credited as Hunt Powers, is an American character actor. He has acted in film, on stage, and on television. He starred in several Spaghetti western films such as Sugar Colt.
Sadarang (1670–1748) was the pen name of the Hindustani musical composer and artist Naimat Khan, who was active in the eighteenth century. He and his nephew Adarang changed the Khayal style of Hindustani music into the form performed today. Naimat Khan composed Khyal for his disciples and he never performed Khyal.
Shahzada Muhammad Yusuf, sometime called S M Yusuf, was a field hockey player who represented two countries namely British India and Afghanistan.
A workbench is a specialized workbench table used by woodworkers. Features include a flat, solid work surface and one or more means of holding the material being worked on.
Jerold T. Hevener was an American film actor and director. He appeared in 36 films and directed a further 18 between 1912 and 1917. He was born in Philadelphia, Pennsylvania. He was married to the actress Grace Clack. He died at Middlesex General Hospital in New Jersey in 1947.
A shaving horse is a combination of vice and workbench, used for green woodworking. Typical usage of the shaving horse is to create a round profile along a square piece, such as for a chair leg or to prepare a workpiece for the pole lathe. They are used in crafts such as coopering and bowyery.
Olney Arnold was the United States Ambassador to Egypt from 1913 to 1916. In 1908 he was a member of the Rhode Island House of Representatives.
A woodworking vise is a type of vise adapted to the various needs of woodworkers and woodworking. Several types have evolved to meet differing primary functions, falling under the general categories of front and end vises, reflecting their positions on a workbench.
