Clamp-on vises are basically very light-duty bench vises. They usually have smooth jaws for wood, plastic and light metalworking, but some have serrated jaws for getting a better grip on metal. Some unique vises combine these features in a rotating design. They also help to secure an object while working on the object.

The vise is often used to hold objects in place when working on a piece. There are two main categories of vise (vice in UK English sp.) : vises on the end of the bench and vises on the front of the bench. End vises (also called 'tail vises') are usually mounted on the right side of the bench for right-handed workers. They can typically hold work in two ways: between the jaws and along the top of the bench using moveable 'dogs' in place of jaws.

Vises that combine the functions of a pipe vise with a metalworker's vise do exist, and are quite common. Some vises have a rotating design to provide both bench and pipe jaws. These are often used by plumbers.

Some engineer's vises marketed as "Homeowner Grade" are not made of steel or cast iron, but of pot metal or a very low grade of iron, typically with a tensile strength of under 10 ksi. Most homeowner's bench vises have an exposed screw. Aluminum soft jaw shown holding five parts at a time in a CNC milling machine.

Some bench designers have adapted face vises for use as tail vises - with differing levels of success. Unfortunately, we are most likely to find the continental style vise used this way, and it's really least suited to the task. When used as a tail vise it has a strong tendency to "wrack" (twist or distort) because of the side forces. It isn't long before the hardware begins to show wear.

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 workbench vises are commonly either face vises, attached to the front of the workbench, near the left end (for a right-handed worker) or end vises, attached to or forming part of the right end of the bench. One common variety of face vise is the leg vise, which has a long extension down to the floor, with a provision to adjust the spacing of the bottom of the leg, to keep the clamping surfaces of the jaws approximately parallel, even though the work to be clamped may be of various thicknesses.

Woodworker's vise with entirely wooden jaws Woodworking vises are attached to a workbench, typically flush with its work surface. Their jaws are made of wood or metal, the latter usually faced with wood, called cheeks, to avoid marring the work. The movable jaw may include a retractable dog to hold work against a bench dog. "Quick-release" vises employ a split nut that allows the screw to engage or disengage with a half-turn of the handle.

In later years the Yankee name would become synonymous with the spiral ratchet screw driver invented by Furbish but it was originally seen on everything from bench vises to cutting tools. Building upon the line of tools originally made by Forest City, North Bros. soon expanded their selection of offerings. Screwdrivers were joined by push drills, breast drills, hand drills (also called egg beater drills), hand powered bench drills, bit and braces, ratcheting tap wrenches, vises, cutting tools and small tool kits.

Commercial production machining now makes use of increasingly advanced chucks which have not only indexable positioning but also indexable clamping.. Both functions are typically hydraulically controlled. The clamping is often done with each pair of jaws consisting of one fixed jaw and one movable jaw (hydraulically actuated), thematically similar to advanced milling vises. This method of clamping brings the high precision and repeatability of such vises to a chucking application. Such chucks offer the centering precision of traditional independent-jaw chucks with the chucking speed and ease of traditional three-jaw self-centering scroll chucks.

The vise consists of two upright planks, one rigidly fixed to the base and the other hinged via a pair of short distance pieces. This can be clearly seen in the small vise on the left of the illustration "Making Shaker brooms". The handle of the broom can pass between the distance pieces, the length of the handle imposing a minimum size on the fixed upright. Larger vises may have the movable jaw hinged at the base and do away with the distance pieces, see the illustration "Shaker broom vises".

Many of the commercial European benches have a front vise that uses a wooden jaw with a metal screw and built-in anti-racking hardware. These vises are also available as inexpensive kits that can be mounted on almost any bench.

It is often used for small castings requiring good tensile strength and the ability to flex without breaking (ductility). Uses include electrical fittings, hand tools, pipe fittings, washers, brackets, fence fittings, power line hardware, farm equipment, mining hardware, and machine parts. Before the widespread use of malleable iron in everyday items, heavy- duty bench vises were made from cast steel. The use of cast steel has rapidly declined in most application due to its poor castability, and hence high- quality cast vises (as opposed to forged ones), among other tools and machine elements, are now almost exclusively made of malleable iron.

Machine vises are mounted on drill presses, grinding machines and milling machines. Abrasive chop saws have a special type of machine vise built into the saw. Some hobbyists use a machine vise as a bench vise because of the low cost and small size.

Not all benches have tail vises. A front vise (also called 'face vise' or 'shoulder vise') is typically mounted on the left front side of the bench. They may be used for holding a board to be edge jointed, or sometimes for sawing out dovetails and the like.

Otherwise changes in temperature and humidity will stress the structure out of shape or it may even break. The most common use for exotic woods in bench construction is for auxiliary parts such as oil cups, bench dogs, vise handles, sawing stops and the parts of wooden vises.

The boards were measured to fit the victim's leg. Once the leg was enclosed, wedges would be hammered between the boards, creating pressure. The pressure would be increased until the victim confessed or lost consciousness. Newer variants have included iron vises—sometimes armed with spikes—that squeezed feet and metal frames employed red-hot.

E. C. Stearns & Company was a manufacturer of tools and hardware in Syracuse, New York and was organized in 1864 as George N. Stearns Company by George N. Stearns, a wagon maker. During the early years, the company was principally involved in the production of hollow iron tools and specialties, hollow augers, and saw vises.

It was known for the manufacture of engines, boilers, grinders, threshers, boring machines, bolt cutters, wood and iron workers' vises, nut facers, etc. There were also foundries and machine shops and manufacturers of lumber products. Some local companies included Frick Company, Geiser Manufacturing, Waynesboro Knitting Mill, Connie's Sportwear, Freeman's Shoes, Landis Machine Company, and Landis Tool Company.

Some vises have a cast iron body but a steel channel bar. Cast iron is popular because it is typically 30,000 psi grey iron which is rigid, strong and inexpensive. 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.

A miniature vise for model assembly with a suction cup base A vacuum vise is a hobbyist's tool, commonly used to hold circuit boards, model airplanes and other small work. They are mounted with a suction cup and often have an articulated joint in the middle to allow the vise to pivot and swivel. Jewelers also use vacuum vises to hold jewelry.

Probably the first such device used two stops - at least one of which was adjustable for position - and wedges between them and the work to fix it in place. This is still a cheap and effective method for holding the work. A screw is really just a wedge in the round. Today, most vises use a big screw to apply the clamping force.

Finally, there is some sort of horizontal beam at the bottom to act as a fulcrum. This beam may take the form of a board that can be adjusted by means of holes and pegs, or it can even be another screw. The leg vise is probably the simplest and least expensive of the front vises, and it is very strong.

The jaw opening of an engineer's vise is almost always the same size as the jaw width, if not bigger. An engineer's vise is bolted onto the top surface of a workbench, with the face of the fixed jaws 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.

These multi-use fixtures tend to be very simple themselves, often relying on the precision and ingenuity of the operator, as well as surfaces and components already present in the workshop, to provide the same benefits of a specially-designed fixture. Examples include workshop vises, adjustable clamps, and improvised devices such as weights and furniture. Each component of a fixture is designed for one of two purposes: location or support.

Visalia is thought to be named for Nathaniel Vises' ancestral home, Visalia, Kentucky. Early growth in Visalia can be attributed in part to the gold rush along the Kern River. The gold fever brought many transient miners through Visalia along the way and when the lure of gold failed to materialize, many returned to Visalia to live their lives and raise families. In 1858, Visalia was added to John Butterfield's Overland Stage route from St. Louis to San Francisco.

According to Sherline, their line of OEM accessories (chucks, vises, rotary tables, and so on) is more comprehensive than that of any other builder of machine tools, regardless of machine size.. Sherline tools are often used by hobbyists for making nearly any kind of part that can be machined, as long as it fits within a miniature machine tool's limits of slide travel. Sherline's products are also used by industry. They provide an inexpensive way to build custom tooling using modular components (XY tables, machine slides, etc.). Sherline's sales are global.

Engineer's bench vise made of cast iron - image inset shows soft jaws A small machine vise used in a drill press A machine vise that can be rotated An engineer's vise, also known as a metalworking vise or machinist's 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. However, most heavy duty vises are 55,000 psi cast steel or 65,000 psi ductile iron.

Like the other simple machines a screw can amplify force; a small rotational force (torque) on the shaft can exert a large axial force on a load. The smaller the pitch (the distance between the screw's threads), the greater the mechanical advantage (the ratio of output to input force). Screws are widely used in threaded fasteners to hold objects together, and in devices such as screw tops for containers, vises, screw jacks and screw presses. Other mechanisms that use the same principle, also called screws, don't necessarily have a shaft or threads.

Junius was also implicated in the confessions of other suspected witches. Court documents describe how Junius at first denied all charges and demanded to confront his witnesses, and continued to deny his involvement in witchcraft after almost a week of torture, which included the application of thumbscrews, leg vises (Beinschrauben), and strappado. He finally confessed on July 5, 1628, in which he claimed that he had renounced God for the Devil and that he had seen twenty-seven of his colleagues at a sabbat. Junius was publicly burned to death one month later.

However instead of a hook being clamped in a vise, tube flies are tied using purpose built tube fly vises or adapters. The small diameter tubing is threaded on a tapered needle until secure allowing the addition of materials without the tube slipping or spinning. The ends of plastic tubes are flared with a heat source either before or after the addition of materials to prevent thread from coming off the end of the tube. Plastic or metal cones are sometimes added at the head of the fly to add weight and or create sonic disturbances in the water.

Tightening the fastener by turning it puts compression force on the materials or parts being fastened together, but no amount of force from the parts will cause the screw to untighten. This property is also the basis for the use of screws in screw top container lids, vises, C-clamps, and screw jacks. A heavy object can be raised by turning the jack shaft, but when the shaft is released it will stay at whatever height it is raised to. A screw will be self-locking if and only if its efficiency \eta \, is below 50%.

A traditional Japanese vise from Japanese homes and their surroundings by Edward S. Morse The traditional Japanese vise was a wedge of wood tied to a post with a coil of rope. The wood was inserted under the wedge and the wedge hammered down. Vises of any sort are used far less in traditional Japanese carpentry than would be the case for equivalent tasks in the traditional crafts of the West. Many tasks in Japanese carpentry associated with building, involve very large pieces of timber, and in general, the weight of the timber and of the carpenter are used to stabilize the piece on which the carpenter is working.

Care must usually be taken to ensure that pressure is applied to the proper bearing race to avoid transferring the pressure from one race to the other through the balls or rollers. If pressing force is applied to the wrong race, brinelling can occur to either or both of the races. The act of pressing or clamping can also leave brinell marks, especially if the vise or press has serrated jaws or roughened surfaces. Flat pressing plates are often used in the pressing of bearings, while soft copper, brass, or aluminum jaw covers are often used in vises to help avoid brinell marks from being forced into the workpiece.

Some crashes may not ever overload any axis or spindle drives. If the drive system is weaker than the machine structural integrity, then the drive system simply pushes against the obstruction and the drive motors "slip in place". The machine tool may not detect the collision or the slipping, so for example the tool should now be at 210mm on the X axis, but is, in fact, at 32mm where it hit the obstruction and kept slipping. All of the next tool motions will be off by −178mm on the X axis, and all future motions are now invalid, which may result in further collisions with clamps, vises, or the machine itself.

Buttress threads have often been used in the construction of artillery, particularly with the screw-type breechblock. They are also often used in vises, because great force is only required in one direction. It is obvious on inspection that a buttress thread with perpendicular face, operating in a split nut, generates minimal disengagement force when tightened in the normally loaded direction, and thus it is possible to derive quick release devices to, for example, allow rapid repositioning of the movable jaw of a vise without having to rotate the screw by many turns. A screw profile, such as acme, where the thrust face is not perpendicular to the axis, generates a significant disengagement force on a split nut, therefore a more robust controlling mechanism would be required.

After Hoffman abducts them to an abandoned zoo, William and his janitor Hank are suspended in chains with large metal vises that will crush their bodies each time they breathe in their oxygen masks. The vise kills Hank as William proceeds to his other three tests to unlock the remaining bomb shackles from his limbs. The second test at an aquarium forces William to save his elderly secretary Addy over his file clerk Allen who hangs to death from his barb-wired noose. At the boiler room, William unwittingly releases his lawyer Debbie who attacks him to retrieve a key inside his body and unlock a speargun attached to her harness but he manages to fight her off until the device kills her.

In CNC, a "crash" occurs when the machine moves in such a way that is harmful to the machine, tools, or parts being machined, sometimes resulting in bending or breakage of cutting tools, accessory clamps, vises, and fixtures, or causing damage to the machine itself by bending guide rails, breaking drive screws, or causing structural components to crack or deform under strain. A mild crash may not damage the machine or tools, but may damage the part being machined so that it must be scrapped. Many CNC tools have no inherent sense of the absolute position of the table or tools when turned on. They must be manually "homed" or "zeroed" to have any reference to work from, and these limits are just for figuring out the location of the part to work with it, and are not really any sort of hard motion limit on the mechanism.

He was born in Bergen, and together with Reidar Bøe Kurt Foss created the hugely popular duo "Radiofantomene" ("The Radio Phantoms") that was active throughout the 1940s, 50s and 60s. Their biggest success was the song "Blåveispiken" ("The Liverwort Girl") with lyrics by Arne Paasche Aasen and which was released in 1950 selling 100,000 records. They later produced humorous songs and tender vises, among these were "Tre yndige små mus" ("Three Cute Little Mice") in 1950, composed by Kristian Hauger, "Nordlandsnetter" ("Nordland Nights") in collaboration with Jens Book- Jenssen in 1952, "Det ringer, det ringer" ("It's Ringing, It's Ringing") in 1953, "Kallen og katten" ("The Old Man and the Cat") in 1954, which was one of several adaptations into songs of the poetry of Jakob Sande, and also "De nære ting" ("The Things Near") in 1951, that song was also with lyrics by Arne Paasche Aasen. After the death of Reidar Bøe in 1969, Foss didn't thrive in the limelight as he had used to.
